 PREFACE. 
 
 In the present revision, the American species of the genus 
 Lithocolletis* are divided into several natural and easily definable 
 groups, based upon structural differences, not sufficient, however, 
 to warrant the establishment of new genera. 
 
 Of necessity, this work is far from complete ; the West remains 
 practically unexplored, and it is to be expected that a large number 
 of species are still awaiting description. It is hoped that this syste- 
 matic arrangement, and the collection of scattered descriptions, 
 rendering identification less difficult, will result in increased effort 
 on the part of those having an opportunity for breeding and collect- 
 ing in little known regions. 
 
 It was the original purpose to give illustrations of every species. 
 The plates contain figures of all of which I was able to see speci- 
 mens. The figures were in all cases sketched by the author from 
 authentic specimens, most of them bred, and often from the types 
 themselves. It will be noticed, however, that the figures of six 
 species are lacking : of one of these, L. alni Wlsm. (= alnivorella 
 Cham.), I have seen no specimens and no type is'in existence; the 
 types of the other five are in the possession of Lord Walsingham, 
 and I regret that my efforts to secure figures of these have been 
 unsuccessful. 
 
 In a number of cases, where the original descriptions are accu- 
 rate and have proved adequate for the identification of the species 
 and varieties, the original is reprinted. Where the species were 
 described in German, translations following as closely as possible 
 the original text are often given. In these cases, I have added my 
 notes collected by breeding and by the examination of additional 
 specimens. Where the original description might have proved mis- 
 leading through peculiarities of the specimen described or through 
 the omission of certain characteristics, new descriptions are printed. 
 The necessity of constant reference to detached fragments, some- 
 
 * Lord Walsingham, in the "Microlepidoptera of Tenerife" (Proc. Zool. Soc. 
 Lond., 976, 1907), has revived the name Phyllonorycter Hb. for this genus.

 times inaccessible, has also been a reason for- giving new, complete 
 descriptions. 
 
 Three European species, formerly included in our fauna, are 
 omitted in the present revision, viz. : alniella Zell., blancardella 
 Fab. and faginella Zell. There is no authentic record of an Ameri- 
 can specimen of alniella; blancardella was included in our lists on 
 * the ground of the supposed synonomy of Clemens' cratcegella with 
 this species ; the occurrence of faginella was based upon the deter- 
 mination by Lord Walsingham of a specimen in Dr. Riley's collec- 
 tion. An examination of this specimen in the National Museum 
 discloses the fact that although a closely related species, it is very 
 distinct from the true faginella of Europe. 
 
 In many cases, where species feed upon plants having a wide dis- 
 tribution, and are known to occur in widely separated localities, it 
 is probable that the range of the species coincides with that of its 
 food plant, and no specific localities have been given for such spe- 
 cies. This is especially true where the distribution of the food plant 
 covers the territory included in the Alleghanian, Carolinian and 
 Austroriparian areas, the "Atlantic States" of Dyar's List. 
 
 My thanks are due to Mr. W. D. Kearfott for the loan of a large 
 number of specimens with notes on their life history, for literature 
 upon the genus, and for the encouragement and assistance which 
 have made my work possible. 
 
 To Dr. Edward Meyrick of Maryborough, England, to whose 
 consideration the proposed division of the genus was submitted, I 
 arn indebted for the expression of his opinion on the establishment 
 of the subgenera, and also for the comparison of several American 
 species with closely related European ones. 
 
 Through the kindness of Dr. Henry Skinner of the Academy of 
 Natural Sciences of Philadelphia, and Prof. Samuel Henshaw of the 
 Museum of Comparative Zoology at Cambridge, Mass., I was given 
 every opportunity to examine and sketch the many valuable types 
 of species of this genus. 
 
 Dr. James Fletcher has sent me a number of Canadian species 
 for examination, for which privilege I return thanks. 
 
 I am under obligations to the U. S. National Museum for the loan 
 of material, and to Dr. Harrison G. Dyar and Mr. August Busck 
 for their courtesy while examining the collection at Washington. 
 
 Mr. G. R. Pilate has kindly sent me mines of a number of spe- 
 cies from California. 
 
 I gratefully acknowledge the assistance I have received from the 
 University of Cincinnati, and my thanks are due to Dr. M. F. 
 Guyer for his interest and suggestions during the progress of my 
 work. ANNETTE F. BRAUN.

 Genus L.ITHOCOLL.ETIS. 
 
 This genus was originally established for a number of European 
 species, which conform to the conception of the genus as defined by 
 Dr. Meyrick in his " Handbook of British Lepidoptera," p. 733. 
 Among our species there are in addition to the typical Lithocolletis, 
 two other groups, distinguished by structural differences, not great 
 enough to warrant the establishment of new genera. In accordance 
 with the opinion expressed by Dr. Meyrick in response to questions 
 regarding the value of these variations in the division of the genus, 
 the solidaginis group and that represented by desmodiella have been 
 ranked as subgenera, but the flat larval group is treated as "a nat- 
 ural and definable group of the genus." 
 
 In order to include all of the American species, the definition of 
 the genus must be somewhat broadened, and it may then be charac- 
 terized as follows : 
 
 Head (Plate XX, fig. 9). Face smooth, crown rough tufted. 
 Labial palpi porrected or drooping, moderately long, pointed. Max- 
 illary palpi rudimentary. Tongue moderate. Antennae nearly 
 attaining the wing length, simple in the male, basal joint thickened, 
 bearing a pecten (without a pecten in subgenus Porphyrosela). 
 
 Forewings elongate, lanceolate, acuminate. 
 
 Hindwings about one- half the breadth of the forewings, linear 
 lanceolate, cilia 4-5. 
 
 Venation (Plate XX, Figs. 1, 2, 3, 4, 5, 6, 7, 8). Forewings : 
 16 simple, 3 absent, 4 absent, 5 absent (typical Lithocolletis and 
 Porphyrosela), 5* and 6 stalked (subgenus Cremastobombycia), 7 to 
 costa, 8 absent, 10 absent, 11 absent (subgenus Porphyrosela). Hind- 
 wings : 3 absent, 4 absent, transverse vein absent between 2 and 5, 
 6 absent (typical Lithocolletis and Porphyrosela), 5 and 6* long 
 stalked (subgenus Cremastobombycia). 
 
 Posterior tibioe with appressed hairs (except in subgenus Porphy- 
 rosela). 
 
 All of the species of which the life history is known are leaf 
 miners throughout their entire larval existence, and all, with the 
 exception of ostensackenella, pupate within the mine. 
 
 The three divisions may be separated by the following characters : 
 
 * Discovery of more primitive forms, with more complete venation, may neces- 
 sitate a change in the interpretation of this venation.

 Our representatives fall naturally into two distinct and well de- 
 fined groups, identical, however, in structural details of the imago. 
 The first, comprising those species having a cylindrical larva, agrees 
 closely with the European species in embryonic stages and in type 
 of markings of the imago. The second group includes all those 
 species having a flattened larva, and is characterized by a definite 
 type of wing marking. 
 
 Most of the species are included in this division, which is well 
 represented in all parts of the country. A very few of the species 
 occur throughout the entire country ; others are of comparatively 
 wide distribution ; a few appear to be confined to a very limited 
 area. 
 
 The following characters will separate the two groups : 
 
 Larva cylindrical; white streaks and fasciae dark margined internally. ..Group I. 
 Larva flattened ; white streaks and fasciae dark margined externally.. .Group II. 
 
ANNETTE F. BRAUN. 273 
 
 GROUP I. 
 
 The larva of the first group (Plate XX, fig. 11) is cylindrical or 
 subcylindrical in form, and has, beside the thoracic legs, four pair 
 of prolegs, on 7, 8, 9 and 13. It is usually of a pale greenish or 
 yellowish color. 
 
 The mine may be placed upon either the upper or lower surface, 
 but in either case the loosened epidermis is lined with silk, causing 
 it to contract, thus producing a roomy, tent-like mine. The mine 
 is at first narrow, somewhat winding, but soon spreads out into a 
 blotch, which sometimes includes the earlier winding portion. The 
 outline of the loosened epidermis represents the final size of the 
 mine, no further increase taking place. The mine may be oval or 
 circular, or in a few cases, nearly rectangular in shape, sometimes 
 limited by two veins. Usually the larva feeds from the circumfer- 
 ence inwardly; sometimes it begins at one end, and sometimes it 
 feeds irregularly in spots. 
 
 With the exception of ostensaclcenella, which leaves the mine to 
 pupate, the pupa is formed within the mine, and may or may not be 
 enclosed in a cocoon. In the latter case, it is usually suspended in 
 the mine by a thin meshwork of silken threads. Where a cocoon 
 is present, several varieties may be distinguished. It may be rather 
 small, ovoid, formed of frass and silk ; large, loosely woven, semi- 
 transparent, occupying sometimes nearly one-half the mine ; or an 
 oval ring with outlines formed of frass. 
 
 The forewings of the imagoes are usually of some shade of yellow 
 or brown, sometimes, however, with the basal two-thirds almost 
 pure shining white. Upon this yellowish ground color, the more or 
 less white markings appear. The transverse markings consist of 
 costal and dorsal streaks, usually curved and oblique, slightly curved 
 or angulated fasciae or combinations of these. These streaks or 
 fasciae are usually margined with darker scales toward the base ; the 
 internal margins of some of the streaks are sometimes lacking. In 
 a few species some or all of the streaks or fasciae may be more or 
 less margined externally also, but in no case is the external margin 
 heavier than the internal one, and in no case is an external margin 
 present, when the internal one is absent. Longitudinal markings, 
 when present, consist of a median streak from the base, sometimes 
 accompanied by streaks along the costal and dorsal margins. The

 apex sometimes contains a well-defined, regularly shaped black dot, 
 formed of closely overlapping scales. In other species, these scales 
 are more or less scattered. 
 
 In the synoptic table, and as a factor in the sequence of the spe- 
 cies, the use of the term "apical spot" or "apical dot" has been 
 restricted to those species in which the apical dot is circular or 
 nearly so, and is not connected with a streak of scattered scales ex- 
 tending along the middle of the wing before the apex. L.fitchella 
 and L. lucidicostella possess typical apical dots. Typically, this dot 
 is placed at the apex of the wing membrane. In intermediate 
 forms, such as morrisella, uhlerella, gemmea, the apical spot may be 
 so increased in size as to occupy the entire apical portion of the 
 wing. 
 
 The white costal and dorsal streaks occupy the interspaces be- 
 tween the veins. The veins then, within certain variable limits, 
 determine the position of these marks. The first costal streak is 
 placed beyond vein 12, and is the most variable in position ; the 
 second just before 11 ; the third between 11 and 9; the fourth be- 
 tween 9 and 7 ; rarely a fifth between 7 and the apex. In those 
 species with but three costal streaks, the one between 9 and 7 is 
 absent, and vein 9 reaches the costa nearer the apex, permitting the 
 third costal streak to be shifted backward. 
 
 Of the dorsal streaks those at the tornus and beyond it are the 
 most constant in position. Those along the dorsal margin have no 
 defined position. 
 
 The species may be separated as follows : 
 
 A. Ground color of the forewings pure white, marked with fuscous irrorated 
 
 bands and bars bataviella. 
 
 A A. Ground color of the forewings not entirely pure white.

 streaks, all black-margined internally except the first, which is very oblique and 
 continued along the costa to the base of the wing. All the costal streaks are 
 short except the first. On the inner margin are two conspicuous silvery dorsal 
 streaks, dark-margined internally, the first very large, and placed near the mid-

 these scales. Within the basal fourth is an angulated fascia, sometimes consist- 
 ing only of the line of black scales which forms its outer border, and sometimes

 interrupted beneath the angle; sometimes the gray scales extend to the base of 
 the wing. Just before the middle is a second angulated fascia, with its dorsal 
 arm more nearly perpendicular than that of the first fascia, also dark margined 
 on its outer side. Beyond this is a somewhat Y-shaped mark, with its arms rest- 
 ing on the costa and enclosing between them a small inwardly dark margined 
 white costal streak. The outer margin of this mark is angulated or interrupted, 
 emitting at the angle a streak of gray scales. This streak unites with an out- 
 wardly concave fascia near the apex. The apical part of the wing is dusted with 
 gray scales, with a few black scales at the apex. A marginal row of gray-tipped 
 scales passes around the apex to the tornus. Cilia pale gray. Expanse 7-7.5 mm. 
 Hindwings and cilia gray. Abdomen gray above, with paler anal tuft, whitish 
 beneath. Legs pale grayish, tarsi tipped with black. 
 
 Described from eight specimens, Cincinnati, Ohio, April 13-29th. 
 
 Not closely related to any described American species, but

 Palpi, face, tuft and antennae glistening snowy white; antennae faintly annu- 
 late above with ocherous. 
 
 Thorax and basal two-thirds of the forewings glistening white, below the fold 
 somewhat suffused with yellow; apical third of the wings pale golden. A pale 
 golden basal streak begins on the costa, extends nearly parallel to the costa for

 fold into the golden apical portion of the wing. In the apical portion there are 
 two costal white wedge-shaped streaks and a similar dorsal one just before the 
 tornus, opposite the first costal streak ; all are internally margined with pale 
 fuscous. A black apical spot. A pale fuscous marginal line in the cilia. Cilia 
 whitish, faintly tinged with yellow. Alar expanse 5 mm. 
 
 Hindwings and cilia whitish. Abdomen pale grayish ocherous above, whitish

 Face, palpi, tuft and antennae white, extreme tips of antennae dark brown. 
 Thorax and basal two-thirds of the forewings shining white ; apical third suf- 
 fused with golden. A rather broad golden basal streak begins at the base on the 
 costa and extends parallel to the fold, to the middle of the wing. In the apical 
 golden portion of the wing, there are three costal white streaks, all dark mar- 
 gined internally, and nearly perpendicular to the margin. Opposite the first 
 costal streak a dorsal white streak, dark margined internally; opposite the sec- 
 ond costal streak is a second indistinct dorsal streak. A black apical spot. CilH 
 whitish, tipped with fuscous around the apex. Marginal line in the cilia dark

 The larvae make tentiform mines on the underside of the leaves of

 Fitch in his description says " three or four costal streaks," mak- 
 ing the description applicable to two species, argentifimbriella Clem, 
 and quercialbella Fitch. Lord Walsingham (Ins. Life, iii, 326, 
 1891) distinguishes quercialbella from argentifimbriella by its hav- 
 ing three instead of four costal streaks. In order to avoid needless 
 confusion, the name quercialbella should be retained for the species 
 having three costal streaks, although Fitch's supposed type of quer- 
 cialbella in the U. S. Nat. Mus. collection is a specimen of argenti- 
 fimbriella.

 The above is Chambers' description of the species. It is common 
 at Cincinnati, Ohio, and may be bred from tentiform mines on the 
 underside of leaves of sugar maple. The pupa is suspended in the 
 mine by a few silken threads. The expanse of the imago is 6-6.5 
 mm.

 "Antennae silvery, annulated with darkish brown. Head, front and thorax 
 silvery-white. Anterior wings silvery, pale golden from nearly the middle to 
 the tip, with a long basal dark brown streak margined above with golden, ex- 
 tending nearly to the first costal streak. There are four silvery costal streaks, 
 all dark margined, the first very oblique, the second convex toward the base of 
 the wing. The first costal dark margin is decided and extended on the costa 
 toward the base. Two silvery dark margined dorsal streaks, the first opposite 
 the second costal streak. The apical spot black, hinder marginal line dark 
 brown, cilia silver-gray. Hindwings silver-gray, cilia the same." 
 
 The above is Clemens' description. 
 
 The larva makes a tentiform mine on the underside of leaves of 
 oaks. The pupa is suspended in the mine in a thin web. 
 
 The imago may easily be distinguished from L. lucidicostella, 
 which it most closely resembles, by having a less portion of the wing 
 golden ; and by differences in the basal streak, which in L. argenti- 
 jimbriella is longer, narrower and dark brown, margined above by 
 a narrow golden line. In L. lucidicostella the basal streak is 
 entirely golden. Expanse 6.57 mrn. 
 
 The type of longistriata F. & B. at the Museum of Comparative 
 Zoology, Cambridge, Mass., is identical with argentijimbriella Clem.

 The above is Clemens' description. As noticed by Stairiton, the 
 statement, " the first costal streak not decidedly dark margined," is 
 an error. This streak is decidedly dark margined, as is also the 
 first dorsal. The extent of the wing suffused with golden also 
 varies ; in some specimens being merely a golden line extending 
 from the golden apical half of the wing along the fold toward the 
 base ; in others the entire basal half of the wing below the fold is 
 golden. Expanse 6.5 mm.

 Antennae white, dark brown at the apex. Face and palpi shining snow-white. 
 Tuft white, mixed with pale yellowish brown scales. 
 
 Thorax shining white. Forewings pale golden brown. There is a broad white 
 basal streak ending in a point at about two-fifths of the wing length and black 
 margined toward the costa. At the basal third is a very oblique costal streak, 
 with its internal black margin produced along the costa to the base. Opposite to 
 its apex is the apex of the larger first dorsal streak, which is continued as a 
 broad band along the dorsal margin to the base. Near the base it is confluent 
 with the basal streak, leaving only a narrow streak of the ground color between 
 its apex and the basal streak. The black margin at the apex of the first dorsal 
 streak extends along its upper edge toward the base for a greater or less distance. 
 In the apical half of the wing are three costal and one or two dorsal streaks. 
 Second costal and dorsal streaks opposite each other, sometimes meeting, and 
 their oblique dark internal margins often uniting in the middle of the wing. 
 Third and fourth costal streaks nearly perpendicular, the fourth sometimes un- 
 margined, the third opposite the third dorsal streak, which is often small or indi- 
 cated by its dark margin only. A black apical spot with a few silvery scales 
 before it. A dark marginal line in the cilia, which are pale golden around the 
 apex, with a gray streak below the fourth costal streak, shading to grayish white 
 toward the tornus. Expanse 6-7.5 mm.

 on their anterior edges. 
 
 Ohio, Kentucky (Chambers), Texas (Boll). Chambers records 
 it on Quercu.s nigra L. ; Boll bred it from Quercus maerocarpa 
 Michx. in Texas. I have bred it at Cincin- 
 nati on Quercus maerocarpa and Quercus 
 platanoides. The rather small tentiform 
 mine may be placed either at the edge of 
 the leaf or between two veins, the loosened 
 epidermis being thrown into numerous longi- 
 Mine of L. aibanoteiia. tudina ] wr j n kles. The pupa is enclosed in 
 
 in a rather large semi-transparent ovoid silken cocoon. 
 
 The type of Chambers' aibanoteiia at Cambridge consists of abdo- 
 men and hind wings only, which are pale grayish ocherous. His 
 description of the species was made from a rubbed specimen, but 
 agrees with that of subaureola in all details, with the exception of 
 " basal fourth of the costa white." As Chambers' type was a 
 female, and in the female the costal portion of the wings toward the 
 base is much paler, this error in the description was probably due 
 to the condition of his specimen.

 "Antennae yellowish, unspotted. Palpi white. Face white, frontal tuft white, 
 with a few saffron scales. Thorax white. 
 
 " Forewings pale saffron, with a rather golden tinge; a broad white basal 
 streak on the upper half of the wing, running parallel to the costal margin for 
 one-third the wing length, thence deflexed and confluent with the middle of the 
 upper edge of the first very broad white dorsal streak. The basal streak is some- 
 times extended at the base across the fold reaching to the dorsal margin, thus 
 leaving between itself and the first dorsal streak a small curved oblique saffron 
 streak; sometimes it is not thus projected across the fold, but upon the dorsal 
 margin beneath it is found a separate short dorso-basal white dash. Above and 
 slightly beyond the point at which the broad basal streak is deflexed there is a 
 very oblique costal streak, somewhat triangular, with its apex reaching nearly 
 to the apex of the much larger first dorsal streak below it; beyond this the sec- 
 ond streak, situated just beyond the middle of the costal margin, is of about the 
 same size, also triangular, a little less oblique, and corresponding with a wider 
 and more conspicuous white dorsal patch opposite to it. The third and fourth

 costal streaks, of which the former points slightly outwards. The latter is per- 
 pendicular, reaching nearly (or in some specimens quite) to a white patch on the 
 dorsal margin before the apex, which seems to consist of two confluent white 
 dorsal streaks. At the extreme apex is a minute black apical spot, surrounded 
 by a semi -circular dark line at the base of the apical cilia, which are tinged with 
 golden saffron at the extreme apex. Beneath the apex the cilia are white, 
 blending into saffron-gray about and before the anal angle ; all the white mark- 
 ings are distinctly dark margined on all sides. The white streaks on the fore- 
 wings of this species are so large and conspicuous as in some cases to almost 
 obliterate the pale saffron ground color, and different specimens vary much in 
 the proportionate space occupied by one and the other. 
 
 "Hindwings and cilia pale gray. Abdomen and anal tuft grayish white. 
 Hind tarsi whitish, spotted above with gray. Expanse alar, 9 mm." 
 
 This species was described as above by Lord Walsingham from 
 specimens collected in California in 1871, in Lake and Mendocino 
 Counties in June, and on Mt. Shasta, Siskiyou County, in August. 
 In Mr. Kearfott's collection, there is a specimen of this species from 
 Carmel, California, taken in June (A. H. Vachell, collector).

 Face, head and thorax white. Palpi white. Scales of the tuft mixed with 
 gray. Antennae remarkably dark gray, with the basal joint white. Upper side 
 of the abdomen dark gray. Anal tuft somewhat lighter, tinged with yellow. The 
 underside of the abdomen is brownish white; as are likewise the legs, the tarsi 
 on the outside being obscurely dark spotted. The ground color of the forewings 
 is a deep saffron brown. The white spots are greatly developed on the dorsal 
 margin, but, on the contrary, only slightly on the costa. Here, beginning just 
 before the middle of the costal margin, are four white streaks dark margined on 
 both sides. The first is placed very obliquely, the second less so, the two last 
 are placed transversely on the wing, are bent, and their apices point toward the 
 tornus. At the base of the dorsal margin there is a very large white spot. It 
 forms an irregular quadrilateral, which approaches the costa, extends parallel to 
 it, and is prolonged to a point on the fold. An obliquely placed transverse band 
 of the saffron brown ground color, very much darkened, borders this spot behind. 
 Then follows a second white mark, in the shape of an irregular triangular, whose 
 broad base rests upon the dorsal margin. There follows a second, also very much 
 darkened shorter transverse band. It ends at one-half the wing length. Behind 
 this at the tornus, we see finally the last white triangle. At the apex of the 
 wing there is a black dot. A well defined black streak extends from this dot 
 into the whitish cilia. A peculiar glistening blue line extends along the base of 
 the cilia. This line becomes very noticeably slightly concave before the tornus.

 The hindwings moderately dark gray, their cilia somewhat lighter. Underside 
 brownish dark gray. The second white dorsal spot usually shows through as a 
 lighter shade. 
 
 The larvae have almost the same habits as those of quercitorum on the under- 
 side of leaves of Quercus Prinus L. and Quercus Castanea Willd. However, the 
 mine is more wrinkled, and hence the leaf is more strongly drawn together and 
 is somewhat gray. 
 
 The imagoes emerge in April and May. 
 
 The above is a translation of Frey's original description (Stett. 
 ent. Zeit., xxxiv, 208, 1873). 
 
 The tuft is saffron brown at the sides. Thorax white, except a 
 narrow brown stripe across the anterior edge of the patagia. The 
 position of a fourth dorsal streak above the torn us is indicated 
 by its dark margin. On large specimens a fifth small white costal 
 streak is sometimes present. The apex of the large white basal 
 dorsal streak is above the fold, not on the fold. Alar expanse 
 7.5-10 mm. 
 
 I have bred this species from mines on the underside of Quercus 
 platanoides (Lam.) Sudw. The pupa is suspended in a few silken 
 
 threads.

 Male. Antennae whitish, annulate with gray. Face and palpi yellowish 
 white. Tuft brown, mixed with ochreous and white scales. 
 
 Thorax whitish, with the anterior portion darkened with grayish brown 
 scales. Forewings pale reddish ochreous. At the basal fourth of the dorsum, 
 there is a curved oblique line of brown scales, uniting at a very acute angle with 
 a shorter curved costal line, thus enclosing a white basal patch, suffused with 
 pale ocherous toward the base and costa and darkened along the costa, with 
 grayish brown scales. There is a small patch of similar dark scales on the dor- 
 sum near the base. Just before the middle of the wing is an oblique white cos- 
 tal streak dark margined on both sides. Nearly opposite it is a large oblique 
 curved dorsal streak also dark margined on both sides, the dark margin being 
 continued from the apex along the middle of the wing to the apex of the second 
 dorsal streak. The anterior margin of the second very broad dorsal streak is 
 formed by a line of brown scales beginning on the dorsum a little anterior to the 
 apex of the first dorsal streak, bent backward along the fold, then directed up- 
 ward. The nearly perpendicular external margin of this streak is formed of a 
 few scattered scales. Second costal streak very long, narrow and oblique, mar- 
 gined internally only, and ending just above the apex of the second dorsal 
 streak. From here to near the apex, the middle of the wing is dusted with 
 whitish scales. Third costal streak triangular and inwardly oblique. Fourth 
 costal streak small. A small patch of brown scales in the apical portion of the 
 wing, from which an indistinct line of brown scales extends to the tornus. A 
 brown line in the cilia passes around the apex from the fourth costal streak to 
 the tornus. Cilia pale grayish. Alar expanse 8 mm.

 streak at the basal third is placed very obliquely, and is produced along the costa 
 to the basal fourth. The first dorsal streak at the basal fourth is very large and 
 very oblique. Near the costa its apex sometimes unites with that of the first 
 costal streak, forming a very acute angle. The remaining three costal streaks 
 are placed at equal distances from each other and from the first costal streak. 
 The second costal streak is almost perpendicular to the costa and wedge-shaped. 
 Opposite to it on the dorsum, before the tornus, is the larger almost perpendicu- 
 larly placed wedge-shaped second dorsal streak. The third costal streak is 
 inwardly oblique, curved, its apex pointing toward the apex of the third dorsal 
 streak, which is small, wedge-shaped and placed beyond the tornus. The fourth 
 costal streak is very oblique and curved. A large black apical dot. A brown 
 line in the cilia extending from the fourth costal streak around the apex to the 
 third dorsal streak. Cilia grayish. Just below the fourth costal streak there is 
 a darker brownish streak in the cilia, giving the appearance of a hook, as in L. 
 fitchella Clem., but not as distinct. Alar expanse 7 mm. 
 
 Hindwings pale grayish, with a slight ocherous tinge. Cilia whitish gray, 
 tinged with ocherous. Abdomen dark gray above, silvery white beneath. Anal 
 tuft grayish ocherous. Legs silvery white slightly shaded with ocherous, tibiae 
 and tarsi of the first pair very dark brown. 
 
 Three specimens, Montclair, N. J., bred by Mr. W. D. Kearfott, 
 from mines on chestnut collected in October, 1901. The imagoes 
 appeared in the following spring. 
 
 I have specimens from Powell Co., 
 Kentucky, on chestnut; and there are 
 a number of specimens in the Nat. Mus. 
 collection bred by Mr. August Busck 
 on chestnut at Washington, D. C. 
 
 The rather small elongate mine of 
 this species is found upon the lower 
 side of the leaf, where it is placed 
 between two veins. The pupa is en- 
 closed in a loose, semi-transparent silken cocoon.

 A single specimen of this very distinct species was bred by Dr. 
 Harrison G. Dyar at Kaslo, B. C. Record number 21563, the food 
 plant being given with some doubt as birch, which is, however, 
 probably correct, as the species bears a close relationship to the 
 European birch feeding species, ulmifoliella Hb.

 Thorax and forewings deep shining reddish saffron. A very narrow line 
 across the patagia is continuous with a broader basal streak, which is white with 
 a golden lustre. The basal streak, ending at one-third the wing length, is dark 
 margined above and indistinctly so beneath. On the dorsal margin, just before 
 the apex of the basal streak is a small broad white spot. Just before the middle 
 of the wing, is a nearly straight fascia, distinctly margined on its inner side with 
 black, and with a few scales on the outer side. Beyond the fascia are two pair 
 of streaks, of which the two costal and the first dorsal are black margined inter- 
 nally. The first pair of streaks are large, triangular and placed nearly perpen- 
 dicular, the dorsal just before the tornus with its apex between the first and sec- 
 ond costal streaks. The second dorsal streak above the tornus is small and oppo- 
 site the second costal streak. Beyond them, the apical portion of the wing is

 Thorax and inner margin of the fore wings beneath the fold dark brown, some- 
 times more golden beyond the fascia. Remainder of the wing golden brown, 
 markings bright shining silvery. In the fold is a silvery basal streak, uniting 
 with the upper side of a nearly perpendicular white dorsal streak at one-third. 
 A little beyond this on the costal margin is a somewhat oblique streak dark mar- 
 gined on both sides. About the middle of the wing, is a slightly convex or 
 obtusely angled fascia dark margined internally and, on its costal half, exter- 
 nally. Beyond this are two perpendicular costal streaks dark margined inter- 
 nally and the former also externally. Opposite to the first of these costal streaks 
 is a dorsal streak whose apex sometimes meets that of the costal. In the fold 
 -between this streak and the fascia is a velvety black streak. Opposite the last 
 costal streak, there is sometimes a small silvery dorsal streak. Apical spot

 white fascia, dark margined internally and toward the costa externally. Beyond 
 this are two nearly perpendicular white costal streaks, dark margined internally, 
 of which the former is opposite a white dorsal streak, just before the tornus. In

 Uhlerella may be distinguished from robiniella by the presence 
 of the first white dorsal streak, the complete median fascia, and the 
 less oblique position of the streaks. It differs from morrisella by 
 the absence of a white basal streak.

 Head saffron brown, face lighter, antennae light brown, annulate with darker, 
 the apex whitish. 
 
 Thorax and forewings shining saffron, rather light, legs yellowish gray, un- 
 spotted ; abdomen dark gray. The marks of the forewings have a strong me- 
 tallic lustre, which is between the color of gold and silver. There are four pair 
 of streaks. The first costal streak is at the basal fourth of the wing length and 
 is obliquely placed. The first dorsal streak is shorter, and nearer the base than 
 the costal streak. Almost in the middle of the wing, th re follow, placed one 
 directly above the other, two more marks, which are tall narrow triangles, some- 
 what dark margined internally, whose apices touch each other. The third pair 
 of markings at three-fourths of the wing length, are very similar to the preced- 
 ing pair, except that the dorsal triangle lies nearer to the base than the costal 
 .triangle. The fourth pair of markings, just before the apex of the wing, consists 
 of a small costal streak, which has inwardly a few dark scales, and a small dorsal 
 streak, which is placed so far back that it is beyond the hind angle. In the apex 
 is a black dot, toward the base overlaid with metallic scales. Cilia light; a dark 
 curved line extends through them at the apex. 
 
 Hindwings and cilia gray. 
 
 On the underside the forewings are dark brownish gray; the marks reappear 
 brownish white. 
 
 The larvae live in fall toward the end of October on the underside of the leaves 
 of Alnus serrulata Willd. The mine is roundish, the loosened epidermis is much 
 wrinkled, resulting in the leaf being rather arched at this place. The imagoes 
 appear in May and June.

 Head, face, palpi and tuft snow white. Antennae white, faintly annulate with 
 ochre-yellow; basal joint ochre-yellow. Tegulse snow white, thorax pale golden 
 yellow. Abdomen whitish gray; legs whitish, tarsi annulate with brown. 
 
 Forewings pale golden brown, marks white. There is a broad basal streak 
 without any dark margining extending for more than two-fifths of the wing 
 length. It begins rather broad, and ends in a long point directed toward the 
 costa. Behind the middle of the wing there is a small, bent, very oblique costal 
 streak, faintly blackish margined toward the base. There is a similarly bent 
 but broader dorsal streak beginning nearer the base and pointing toward the first 
 costal streak. On the costa follow very small, faintly inwardly dark margined 
 streaks. A fourth one is indicated by a few white scales. At the hind angle is 
 an inwardly blackish margined white dorsal triangle. It apex extends between 
 the second and third costal streaks. From this, a line of blackish scales extends 
 toward the terrnen. Cilia whitish, with a blackish basal line. The latter only 
 extends around the apical part of the wing. [Expanse 6 mm.] 
 
 Hindwings light, yellowish gray, cilia whitish. 
 
 This species, the habitat of. which is given as Texas, is an under- 
 side miner on scrub oak. A peculiar characteristic of the mine, as 
 noted by Frey and Boll, is its transparent appearance, when mature, 
 allowing the pupa to be plainly visible through the epidermis.

 The pale golden brown (approaching the color of L. faginella) faintly shining 
 forewings have peculiar white markings. There is a short narrow basal streak 
 dark margined toward the costa, ending just before the two-fifths of the wing 
 length. The first costal streak beginning at two-fifths is placed very obliquely, 
 is dark margined toward the base, sharply bent at an angle in the fold, and is 
 then prolonged as a very short spur toward the dorsum and base. Beginning 
 under the apex of the basal streak, and extending toward the costal streak, is a

 rather small and bent dorsal streak, also placed very obliquely. It does not 
 attain tbe fold, and ends at some distance from tbe short. spur of the costal 
 streak. In the apical half of the wing there are three more small costal streaks, 
 dark margined toward the base. On the dorsum there is a considerable sized 
 streak of the shape of an equilateral triangle, whose apex, covered with black 
 scales, projects between the second and third costal streaks. There are a few 
 white scales in the apical portion of the wing. The cilia at the apex of the wing 
 are shining and of the wing color, with a blackish basal line. Toward the hind 
 angle they become yellowish gray. 
 
 Hindwings light gray. Cilia lighter. The underside of the forewings is 
 brownish gray. 
 
 The mines, which produced the specimens, from which Frey and 
 Boll described the species, were found by Boll in eastern Texas on 
 the underside of leaves of Quercus rubra L. They are roundish, 
 small and slightly wrinkled. 
 
 No exact expanse is given, but the statement is made that the 
 species is small.

 Of medium size; however, several specimens are considerably smaller; rather 
 broad-winged. The ground color of the head, thorax and forewings is a peculiar 
 light yellowish brown. This color is similar to that of a flown specimen of L. 
 connexella Z. The forewings are finely scaled. Head and palpi brownish white. 
 Antennae brownish white, annulate with darker. The legs are brownish white, 
 the tibige of the first pair are striped with black. Thorax concolorous with the 
 wings, with a median whitish line. Patagia whitish. Abdomen gray, lighter at 
 the tip. 
 
 The markings of the forewings are somewhat indistinct, but are characteristic 
 because of the great accumulation of black scales in the region of the fold. They 
 are as follows: there is a rather straight basal streak ending at one-third tbe 
 wing length, where it is slightly dilated. It is margined with blackish around 
 the apex. The first pair of streaks are placed very obliquely. Of these, the 
 costal is the smaller and is triangular. The dorsal is of very peculiar form, in 
 that it is strongly constricted on the fold. Both are black margined internally. 
 Usually the extent of the black scales on the inner edge of the dorsal streak is 
 so greatly increased as to form a considerable sized black spot, which extends to 
 the apex of the basal streak. (Less frequently these black scales are almost 
 lacking). The next pair of streaks are at the middle of the wing length, and are 
 also inwardly black margined. (These black scales are also increased so as to 
 form a spot.) The costal streak is narrow, almost perpendicular; the dorsal 
 forms a broader triangle, placed just before the tornus. Toward the apex are

 two very narrow, slightly curved streaks. At the apex is a black dot or a streak, 
 bordered with white scales toward the base. Cilia light, darker toward the tor- 
 nus, with a blackish marginal line around the apex. 
 
 Hindwings dark gray. Cilia somewhat lighter. 
 
 The last three light costal streaks are visible on the dark brownish underside 
 of the fore wings. 
 
 The larvae are abundant in October and November on several species of Ralix. 
 The mine is on the underside between the veins. It is elongate-oval and some- 
 what wrinkled. The imagoes emerged in April and May. 
 
 The above is a translation of Frey's description of L. scudderella. 
 The second costal streak is placed rather beyond the middle than at 
 the middle. In some specimens, there is also a third dorsal streak 
 above the tornus. The apical black marking, when a streak, is 
 often margined not only before with white scales, but also above for 
 its whole length. Alar expanse 7.5-9 mm.

 Lithocolletis salicivorella Braun, Ent. News, xix, 101, 1908. 
 
 Antennae pale grayish ocherous, faintly annulate with darker, somewhat 
 darker at the tip. Palpi shining white. Face white. Tuft pale gray, with an 
 ocherous tinge. 
 
 Thorax and basal third of the forewings ocherous gray. Wings becoming 
 more ocherous towards the apex. A white band across the anterior margin of 
 the thorax extends aeross the patagia and is continuous with a median basal 
 white streak on the forewings. There is a short dorso-basal white streak some- 
 what dilated posteriorly. The median basal streak is curved downward and 
 extends for two-fifths of the wing length where it is confluent with the first dor- 
 sal streak, its upper edge uniting with the apex of the first dorsal streak. A few 
 dark brown scales extend around the apex of the angle thus formed. There are 
 four costal and three dorsal white streaks. The first dorsal streak at the basal 
 fourth is very large, oblique and curved. Internally it is dark margined just 
 before it unites with the basal streak, the dark margin being continued around 
 the angle and for a short distance along the lower side of the basal streak. The 
 extreme edge of the costa is dark brown for about one-third of the wing length, 
 where the dark line is deflexed and continues as the dark margining of the first 
 costal streak, which is narrow, very oblique, its apex extending to a point just 
 beyond the apex of the first dorsal. The second costal streak is large, nearly 
 perpendicular, its apex opposite to that of the second dorsal streak, which is also 
 very large, and placed slightly nearer the base than the corresponding costal 
 streak, and is somewhat oblique. The next pair of streaks, of which the dorsal 
 is placed just above the tornus, are nearly opposite to each other, slightly oblique 
 toward the base and curved ; their apices nearly meet. These two pair of 
 streaks are margined internally with brown scales. Fourth costal streak oblique, 
 curved and unmargined. A narrow line of black scales extends from below the 
 apex of the last costal streak to near the apex of the wing, and is margined above 
 by a line of white scales. Marginal line in the cilia dark brown, extending 
 around the apex from the fourth costal streak to the third dorsal. Cilia grayish 
 ocherous. Alar expanse 7 mm. 
 
 Hind wings grayish. Cilia gray, with a fulvous tinge. 
 
 Abdomen dark gray above, whitish beneath. Anal tuft grayish ocherous. 
 Legs whitish, banded and striped with gray.

 Face, palpi and antennae white; antennae faintly annulate with brownish. 
 Tuft pale brownish ocherous, mixed with white. 
 
 Thorax and forewings pale golden brown. Three longitudinal white streaks 
 on the thorax, the median one continuous with a short narrow dorso-basal white 
 streak, the other two uniting with the unmargined median basal streak, which 
 curves downwards and unites with the upper edge of the slightly oblique nearly 
 square first dorsal streak, which is faintly margined internally by a darker shade. 
 The first costal streak, a little beyond it, is triangular, somewhat oblique, and 
 dark margined on both sides. Second costal streak nearly perpendicular and 
 opposite the larger triangular second dorsal streak, both faintly dark margined 
 before. Last two costal streaks small, oblique and faintly internally margined. A 
 third dorsal streak above the tornus is indicated by its dark margin. Beginning 
 under the apex of the third costal streak is a dark brown streak of scales, extend- 
 ing to the apex. A brown marginal line extends around the apex, at the base of 
 the cilia, which are pale whitish ocherous. Expanse 6 mm. 
 
 Hindwings and cilia pale grayish, slightly fulvous. Forelegs pale, tibiae and 
 first tarsal joint reddish.

 This species has been made a synonym of blancardella (Walsing- 
 ham, Trans. Am. Ent. Soc., x, 202, 1882). An examination of 
 Chambers' type shows it to be a distinct species, not closely related 
 to .eratcegella or the other apple feeding species. It differs from 
 cratcegella in the less oblique first costal streak ; in the confluence of 
 the unmargined basal streak with the first dorsal streak, which is 
 entirely different from the first dorsal streak of eratcegella; and in 
 the absence of any very distinct dark margining of the streaks.

 to one-third the wing length, and a shorter streak of the same color follows the 
 dorsal margin from the base to half the length of the one ahove it; the first dor- 
 sal streak is broad, outwardly oblique, and reaching nearly to the smaller trian- 
 gular costal streak above it; in some specimens it actually attains to it, forming 
 an angulated fascia; the point of the second dorsal, also somewhat triangular, is 
 directed a little beyond the point of the second costal streak above it; these are 
 both nearly perpendicular; the third dorsal very small; arising opposite the 
 space between the third and fourth costal streaks; it reaches to the apex of the 
 former; the end of the wing is enclosed by a dark semi-circular line at the base 
 of the cilia, within which is an elongate blackish spot ; cilia are grayish, with a 
 faint saffron tinge. 
 
 "Hindwings and cilia pale grayish. Abdomen gray above, anal tuft scarcely 
 paler. Posterior tibiae, whitish, unspotted. Expanse 6 mm." 
 
 "Two specimens were bred from larvae found mining the upper 
 sides of leaves of Alnus incana on Mount Shasta, Siskiyou Count} 7 , 
 Cal., in August, 1871, in which month the perfect insects emerged. 
 Three other specimens were met with on the wing, also in the 
 neighborhood of Mount Shasta."

 "Palpi and antennae rather short for this genus, and tuft on the vertex also 
 small ; face, palpi, under surface of the thorax and abdomen and the legs silvery, 
 the palpi a little darker on the outer surface; antennae and tuft silvery fuscous, 
 or perhaps as correctly ash-brown ; upper surface of thorax and forewings egg- 
 yellow, varying to golden with change of light. There is a short basal, silvery 
 white streak along the dorsal margin of the forewings, and a longer median 
 basal streak of the same color, and dark margined toward the costa. A silvery 
 white fascia immediately before the middle, posteriorly obtusely angulated about 
 the middle of the wing, and dark margined before, the dark margin becoming 
 more diffuse along the dorsal margin, where it is produced forwards until it meets 
 the basal dorsal white streak ; the point of the angle of the fascia is sometimes 
 margined behind by a small dark brown spot, and the fascia is widest on the 
 dorsal margin ; just behind the middle is a costal silvery white streak, and oppo- 
 site to it is a dorsal one, both strongly dark margined before, and both pointing 
 a little obliquely backwards, this dorsal streak is placed immediately before the 
 cilia, and a little further back is a small triangular dorsal silvery spot, dark mar- 
 gined before; opposite to the space between these two is a straight silvery costal 
 streak, also dark margined before, which sometimes bends backwards and unites 
 with the second of the dorsal streaks referred to above; whilst its dark margin 
 bends forwards and unites with the dark margin of the first one; further back 
 is a third costal streak, which is small, straight and dark margined before.

 The larva is cylindrical, and makes a large tentiform mine on the under surface

 The above is Chambers' description. This species is apparently 
 close to alnicolella Wlsm., the principal difference being in the lar- 
 val habits, as noted by Lord Walsingham, under his description of 
 alnicolella. I have seen no specimen and no type is in existence. 
 
 Lithocolletis malimalifoliella Braun.

 Lithocolletis malimalifoliella Braun, Ent. News, xix, 101, 1908. 
 
 Antennae gray. Palpi silvery white. Face silvery white. Tuft golden brown, 
 tipped with dark brown. 
 
 Thorax and forewings golden brown. There are three longitudinal stripes on 
 the thorax, one median, the other two passing over the patagia and continuous 
 with a median white basal streak, ending at one-third the wing length and dark 
 margined above and around the tip behind. The dorsal margin is also white for 
 a short distance. There are three costal and two dorsal white streaks of which the 
 dorsal are the larger, all dark margined before, and the first pair dark margined 
 at the tip behind. The first costal at the basal third is small, oblique. The first 
 dorsal at the basal fourth is very large, oblique and curved, ending just before 
 the apex of the first costal. The second costal streak is small, nearly perpendic- 
 ular, and opposite the second dorsal, which is triangular, and placed just before 
 the tornus. The third costal streak, at the same distance from the second as the 
 latter is from the first, is somewhat oblique, pointing forward. A third dorsal 
 streak is indicated by the dark margin. An elongate black apical spot, witb a 
 few scattered brown scales before it. Marginal line in the cilia blackish with a 
 distinct blue lustre around the apex. Cilia gray, brownish around the apex. 
 Alar expanse 5.5-6 mm. 
 
 Hindwings dark gray. Cilia gray. Abdomen very dark gray above, silvery 
 white beneath. Legs gray, hind tarsi blackish, grayish at their bases. 
 
 I have bred this species from small tentiform mines on the under- 
 side of leaves of apple, Mains Mains (L.) Britton. The appearance 
 of the mine is entirely different from that of L. cratcegella Clem. 
 The mine is much wrinkled, and the leaf is strongly folded. The 
 parenchyma is eaten in spots, giving the leaf a speckled appearance 
 on the upperside. The pupa is suspended in a few silken threads. 
 I also have flown specimens from Montclair, N. J., which are identi- 
 cal with the bred specimens. 
 
 There are two specimens of this species in the Museum of Com- 
 parative Zoology at Cambridge, Mass., bred by Chambers on quince, 
 in Kentucky. 
 
ANNETTE F. BRAUN. 301 
 
 The mine also occurs on Cratcegus mollis Scheele, and then the 
 parenchyma is almost completely consumed. 
 
 Occasionally, specimens of cratcegella occur in which the fourth 
 costal streak is wanting, but malimalifoliella may be distinguished 
 from these by the relative position of the third costal streak, which 
 is placed farther back, almost equally dividing the space between 
 the second costal and the apex.

 Antennae dark silvery gray. Face and palpi silvery. Tuft dark brown, mixed 
 with whitish scales. 
 
 Thorax and forewings brownish golden, with a silvery basal streak continuous 
 with a white line on each side of the thorax and extending for two-fifths of the 
 wing length, black margined toward the costa and around its pointed apex. 
 Dorsal margin narrowly white toward the base. Four costal and two or three 
 white dorsal streaks, of which the first costal and the first two dorsal streaks 
 are dark margined on both sides, the others internally only. The first costal 
 streak, beginning at two-fifths, is oblique and rounded beneath, its internal mar- 
 gin produced along the costa to the base. The other three costal streaks are 
 nearly perpendicular. The first dorsal streak, somewhat nearer the base than 
 the first costal streak, also oblique, its apex a little beyond that of the first costal 
 streak, which it also touches. Second dorsal streak triangular, just before the 
 tornus and opposite the second costal streak. From the space between the second 
 pair of streaks, a streak of dark scales extends to the apex. Marginal line in 
 cilia blackish, with a decided bluish lustre. Cilia grayish ocherous. Expanse 
 6.5-7 mm. 
 
 Hindwings and cilia gray. Abdomen dark gray above, silvery beneath, with 
 more ocherous anal tuft. Legs grayish, hind tarsi spotted with fuscous above. 
 
 An underside miner on several related plants, viz. : Cratcegus

 rather small, usually lying between two veins. A common species 
 in the eastern United States. 
 
 This species is distinct from any of the apple feeding species of 
 Europe. It has been made a synonym of L. blancardella Fab., 
 from which it differs in the much smaller size, more pointed basal 
 streak, and less oblique first pair of streaks.

 Thorax brownish golden, with a white line across the. anterior margin, passing 
 over the patagia and continuous with the basal streak on the forewings. Fore- 
 wings brownish golden in the male and darkened with brownish scales along 
 the middle and in the dorsal half; more golden in the female. The rather broad 
 basal streak, pointed at the apex, ends at about two-fifths of the wing length 
 and is black margined above and around its apex. Dorsal margin narrowly 
 white toward the base. Four costal and three dorsal white streaks. First costal 
 just before the middle, very oblique, and dark margined internally and around 
 its tip behind. The other three costal streaks nearly perpendicular and dark 
 margined internally only. First dorsal streak commencing much nearer the 
 base than the first costal, long and oblique, its apex reaching beyond that of the 
 first costal, sometimes almost to the space between the second costal and dorsal 
 streaks. It is dark margined on both sides. In the male its internal dark mar- 
 gin is indented on the fold, in the female it is almost regularly inwardly convex. 
 An accumulation of blackish brown scales, densest in the male, between the sec- 
 ond pair of streaks extends backward along the middle of the wing to the apex. 
 Marginal line in the cilia blackish, with a bluish metallic luster. Cilia grayish 
 ocherous, less gray in the female. Expanse 8-9 mm. 
 
 Hindwings and cilia grayish, with a fulvous tinge. Abdomen 
 dark gray above, silvery beneath. Anal tuft grayish in the male, 
 ocherous in the female. Legs grayish ocherous, tarsi gray above.

 A much more common species than L. cratcegella Clemens, and 
 more closely related to the European blancardella,i'rom which, how- 
 ever, it is distinct. It differs from cratcegella in the much larger 
 size and the more oblique first dorsal streak, which is also relatively 
 much nearer the base of the wing than in cratcegella.

 and reaches a little beyond the costal streak beyond it; the second costal streak 
 is small and points slightly outwards; the third is nearly perpendicular; the 
 fourth points slightly inwards from a little before the apex ; these three are all 
 dark margined on their inner edge; opposite to these are the second and third 
 dorsal streaks; the second is triangular, wider at the base and dark margined 
 internally, its black dusting communicating with a patch of similar blackish 
 scales at its apex, extending to the second costal streak above it; the third dorsal 
 streak is short, pointing inwards and. dark margined on both sides, its outer mar- 
 gin being continuous with a dark line at the base of the cilia, which encircles the 
 tip of the wing, reaching to the exterior costal streak ; within this line, but sep- 
 arate from it, is an elongate apical spot of somewhat disconnected blackish 
 scales, the cilia pale grayish. 
 
 "Hindwings and cilia pale grayish. Abdomen dark gray above, anal tuft 
 somewhat paler. Hind tarsi white, tipped with grayish and two grayish saffron

 " The larva feeds in mines on the underside of Alnus incana 
 toward the end of June in Colusia County, Cal., the perfect insects 
 emerged in July, 1871. Seven specimens were bred, and the species 
 was also met with on the wing at Burney Creek (near Pit River), 
 Shasta County, Cal." 
 
 The above is Lord Walsingham's description. 
 
 The mines also occur upon the upperside of the leaf. I have bred 
 a large series of specimens on a species of Alnus from Alameda 
 County, Cal., where the mines are very common on the upperside 
 of the leaf, but appear very rarely on the lower side. Some speci- 
 mens have the basal streak faintly margined above, especially 
 toward the apex.

 "Palpi, head, tnft, antennse, under surface of the thorax, legs, and abdomen 
 pure snowy white; upper surface of abdomen and forewiugs pale golden ; there 
 are three white longitudinal streaks on the thorax (one median, and continuous 
 with a dorso-basal white streak on the wings, the other two passing over the 
 tegulse, and continuous with a median basal white streak on the wings) ; there 
 is also a costo-basal white streak on the foi'ewings, and these three basal wing 
 streaks are of about equal length, and less than one-fourth of the length of the 
 wings. Immediately behind the dorso-basal streak, and scarcely distinct from it 
 (probably sometimes confluent with it), is the first dorsal streak, which ap- 
 proaches a square form, and is dark margined before and above. Almost oppo- 
 site to this dorsal streak, bu^ a little behind it, is the first costal streak ; it is 
 oblique, not pointed, and is dark margined before. The second costal and second

 dorsal are opposite each other, the costal one being the largest of the two, trian- 
 gular and dark margined before. The third costal and third dorsal are nearly 
 opposite, the costal being perhaps a little farther back, and being larger than the 
 dorsal, and larger also than the second costal ; both are dark margined before. 
 These are the only three dorsal streaks. The fourth costal is just before the 
 apex, points a little obliquely forward, and is margined behind by a small apical 
 patch of brown dusting. Cilia white, with a brownish hinder marginal line at 
 their base. Alar expansion one-fourth of an inch. Ohio and Kentucky." 
 
 The above is Chambers' original description. The second and 
 third costal streaks can scarcely be said to be larger than their cor- 
 responding dorsal streaks; usually they are about the same size. 
 There is also some variation in the amount of apical brown dusting ; 
 sometimes it only consists of two or three scales. The expanse is 
 6-7 mm. 
 
 I have bred this species from tentiform mines on the underside of 
 the leaves of the silver leaf poplar, Populus alba L., the same food 
 plant from which Chambers bred this species. The mines are ex- 
 ceedingly small, oval, 9-10 mm. long, and 4-5 mm. broad ; an indis- 
 tinct fold extends through the long axis. They are scarcely visible 
 on the lower side, owing to the peculiar tomentose texture of the 
 leaf, and on the upperside may be distinguished by the speckled 
 appearance of the leaf, caused by the larva eating the parenchyma 
 in spots. The pupa is not enclosed in a cocoon, but its anal end is 
 attached to a small button of silk toward one end of the roof of 
 the mine.

 Face and palpi white; antennae whitish, darker at the tips; tuft very pale

 Thorax and forewings very pale golden. Four costal and three dorsal white 
 streaks (the third dorsal obscure and sometimes wanting); of these the first two

 While very closely allied to ceriferella Clem., sexnotella may be 
 distinguished by its paler color, the pure white dorsal and costal 
 streaks, and by having its second dorsal streak opposite the space 
 between the second and third costal streaks. The internal margins 
 of the corresponding costal and dorsal streaks never unite in the 
 middle of the wing.

 "Antennae dark brown above, white beneath. Front silvery white; tuft dark 
 brown. Forewings pale reddish saffron, with a golden hue, especially from the 
 middle to the base, with four silvery costal streaks, the first on the middle of the 
 costa, and all, except the lust, black margined toward the base, the third but 
 faintly, and the costa black from the base to the first costal streak. Three sil- 
 very dorsal streaks on the inner margin, the first two large and the third small, 
 the first black margined internally and around the tip behind, the second by a 
 line curved above. Apical spot small and black, with the scales behind it having 
 a bluish splendent lustre; hinder marginal line blackish; cilia dark grayish, 
 with a fulvous hue. Hind wings dark gray, cilia fulvous. 
 
 "The larva may be found in the leaves of oaks in September and early in 
 October. It makes a small mine on the under surface, and the leaf is thrown 
 into a fold previously to pupation and the cuticles folded and corrugated. . The 
 pupa is contained in an ovoid cocoon, within the mine, composed of "frass" 
 and silk. The imago appears in May. The body of the larva is cylindrical. 
 The head is pale brown; the body yellow, with a broad, vascular, reddish 
 brown band." 
 
 The above is Clemens' description. 
 
 The white color of the costal and dorsal streaks, especially the 
 first pair, is often suffused with pale golden. The margins of the 
 second and the third costal streaks, in the middle of the wing, 
 where they are of a dull leaden color, unite with the margins of 
 their opposite dorsal streaks. In some of my specimens bred at 
 Cincinnati from mines on Quereus imbricaria Michx., the dark mar- 
 gin of the second dorsal streak is very heavy and conspicuous.

 "Antennse silvery. Front and tuft silvery. Thorax pale reddish saffron, with 
 a rather short, unmargined, silvery basal streak, with, five costal and four dorsal 
 streaks of the same hue. The first costal and dorsal streaks unmargined, the 
 first dorsal being near the inner angle of the base, tapering to a point in the mid- 
 dle of the wing from a very broad base ; the first costal streak rather slender, and 
 only one-half as long as the first dorsal; the second costal and second dorsal con- 
 nected about the middle of the wing, and dark margined toward the base by a 
 line much curved in the middle; the third costal and third dorsal opposite, and 
 each dark margined internally; the fourth dorsal about midway between the 
 fourth and fifth costal streaks; sometimes the fourth costal and dorsal streaks 
 with a few dark internal scales, sometimes unmargined. At the apex is a small 
 patch of scattered black scales; the hinder marginal line rather indistinct; cilia 
 saffron, paler on inner margin. Hindwings shining silver-gray, cilia rather 
 darker."

 A white transverse band across the anterior margin of the thorax, 
 crossing the patagia, continuous with the basal streak, is not men 
 tinned in the description. The tuft is golden at the apex. Abdo- 
 men yellowish fuscous above; anal tuft yellow. Legs whitish, 
 spotted with brown. Alar expanse 6.5-8 mm.

 Face and palpi white; tuft white, with a few brownish scales; antennae whit- 
 ish, faintly annulate with yellowish; legs whitish, spotted with brown. Abdo- 
 men gray. 
 
 The thorax (with a white line across the patagia) and the forewings are deep 
 saffron. They are lustreless, and their markings are pure white. At the base 
 of the wings in the fold there is a very short white streak. At the basal fifth 
 there begins on the dorsal margin a broad, back ward ly bent, oblique cross streak, 
 whose pointed apex does not reach the costal margin. At the middle of the 
 wing length there is a narrow, slightly horse-shoe shaped complete fascia, 
 inwardly narrowly dark margined. A third similarly formed fascia appears at 
 three-quarters of the wing length. Each of these is darkened or interrupted in 
 its costal half, as in the middle by a group of brown scales. In the apical part 
 of the wing there are some more scattered brownish scales. The cilia around the 
 apex are saffron gray, around the hind angle entirely light yellowish gray. 
 
 The hindwings and cilia are whitish. 
 
 According to Frey and Boll, whose description is given above, 
 this species may be bred from an underside rather arched mine on 
 Ulmus fulva Michx. 
 
 Hab. Texas. 
 
 J have had no opportunity of examining specimens of this spe 
 cies. Further study and breeding of a large series may show that 
 it is not specifically distinct from argentinotella Clem.

 Thorax and forewings pale grayish ocherous. Markings ocherous white and 
 usually very indistinct and ill-defined. When distinct, they consist of a pale

 middle an oblique costal and a dorsal streak, faintly or not at all dark margined 
 internally, which sometimes unite to form an angulated fascia; three more 
 nearly perpendicular costal streaks; a dorsal streak before the toruus, oblique 
 and pointing toward the third costal streak; sometimes two more dorsal streaks 
 above the tornus, which unite with the third and fourth costal streaks respec- 
 tively, thus enclosing the apex, which then contains a small patch of blackish 
 scales. Usually, the last two dorsal streaks are wanting, and the black scales are 
 so increased as to occupy the entire apex, a line of them extending to the tor- 
 nus. Often all of the marks are very ill-defined and the entire thorax and dor- 
 sal portion of the wing below the fold is of the pale color, and the black area 
 at the apex is very pronounced. Alar expanse 6.5-7.5 mm. 
 
 Hindwings and cilia pale grayish ocherous. Abdomen pale gray, with silvery 
 anal tuft. Legs pale silvery ocherous. 
 
 Described from a series of specimens bred from mines on the 
 underside of leaves of a species of Salix, received from Mr. G. R. 
 Pilate, Mills College, Alameda Co., Cal., and from two captured 
 specimens in the U. S. Nat. Mus., from Seattle, Wash. (Prof. T. 
 Kincaid, collector).

 "Antennae silvery. Front silvery, tuft fulvous, mixed with silvery. Thorax 
 pale, reddish golden, with a white streak on each side, and one in the middle. 
 Forewings shining ocherous saffron, with a slender unmargined white basal 
 streak in the fold, a white basal streak along the costa, narrowly dark margined 
 on the extreme costa, extended to the first costal streak, which is silvery white, 
 very oblique and unmargined ; behind this are three small costal streaks of the 
 same hue, the two central dark margined internally. Opposite the first costal 
 streak is a long, very oblique, silvery white dorsal streak, extending along the 
 inner margin to the base, with dark brown scales between their hinder ends, or 
 exterior to the tip of the dorsal streak, but sometimes absent. Nearly opposite 
 the third costal streak is a dorsal silvery streak dark margined internally. No 
 apical spot, sometimes with dispersed brown scales beneath the last costal spot. 
 The hinder marginal line blackish ; cilia pale fulvous. Posterior wings gray; 
 cilia gray, with a fulvous hue." 
 
 The alar expanse, omitted in the original description, is 8 mm. 
 
 The mines of this species are very common on the underside of 
 leaves of oaks. The mine lies between two veins and is nearly rec- 
 tangular in shape and unwrinkled. At the time of pupation, the 
 
ANNETTE F. BRAUN. 309 
 
 frass, which has been deposited along the edges of the mine, is col- 
 lected and made into an oval ring-like wall of the cocoon, leaving 
 the cuticle transparent, through which the pupa is plainly visible. 
 It ranges throughout the entire United States. Specimens collected 
 by Lord Walsingharn in California and Oregon (of which there is 
 a specimen in the U. S. Nat. Mus.) are identical with the eastern 
 specimens, but somewhat larger and the white streaks are a little 
 broader and more distinct.

 "Face, palpi and under surface silvery white, the under surface and legs 
 tinged with yellowish ; antennae silvery, annulate above with dark brown. Tuft, 
 thorax and anterior wings saffron yellow, with a white patch in the center of 
 the tuft and the usual white line across the anterior margin and sides of the 
 thorax, which, however, as in other species, is sometimes wanting. When pres- 
 ent it is confluent with the rather long narrow median basal white streak, which 
 is faintly dark margined towards the dorsal margin. Just before the middle is 
 a white fascia, angulated near the costa and produced backwards at the angle, 
 and strongly dark margined internally. Near the base of the cilia is another 
 straight white fascia not definitely bounded, anteriorly margined with dark 
 brown and with many dark brown scales interspersed in the white, and some- 
 times divided into two or three rather indefinite spots. The apex of the thorax 
 is white, and from it a narrow white line passes along the posterior margin of 
 the wing to the first fascia, and sometimes is faintly indicated to the base of the 
 cilia and is margined with dark brown. Apex dusted with dark brown on a 
 white ground, the dusting margined by an oblique white line internally. Some- 
 times the dusting is not thick, and the whole apical half of the wings is sparsely 
 flecked with dark brown scales. The markings of the apical half of the wing are 
 all indefinite, the colors not being separated by distinct well-marked lines, but to 
 some extent running into each other. Alar expanse less than one-fourth inch. 
 Kentucky. Very abundant. There is some variation in the intensity of the 
 color, some species being much paler than others, and one specimen in my pos- 
 session has the thorax entirely white." 
 
 In the original description, which is reprinted above, Chambers 
 says that the basal streak is "faintly dark margined toward the 
 dorsal margin." In all my specimens (bred), the streak is mar- 
 gined toward the costa and not at all on the dorsal side. The first

 fascia in celtisella occupies nearly the same position as the second in 
 celtifoliella. 
 
 This species has been made a synonym of celtifoliella, but an ex- 
 amination of specimens of each and a comparison of the early stages 
 shows that celtisella and celtifoliella are specifically distinct. 
 Food plant, Celtis occidentalis L. 
 
 The larva, of the cylindrical type in the later stages, enters the 
 leaf on the lower surface, and makes a narrow linear mine, then 
 
 cuts through the parenchyma 
 to the upper side, where the 
 mine broadens into an elon- 
 gate blotch, made tent-like by 
 a longitudinal ridge in each 
 epidermis. The larvse eat the 
 entire parenchyma, leaving 
 merely the dark discolored 
 cuticles of the leaf. 
 The mines and imagoes of this species are very abundant. Its 
 range is wide, and probably coincides with that of its food plant.

 Antennae, palpi, face and tuft shining white. Thorax and basal half of the 
 forewings shining white. Apical part of the forewings suffused with golden. A 
 golden costal streak from the base, not extending to the middle. At about the 
 middle is a silvery white fascia, broadly margined with golden on its inner side, 
 and with a black spot on the costa internally. This fascia is also sometimes mar- 
 gined internally towards the dorsal margin with a few black scales. In the 
 apical portion of the wing are two white costal streaks; the first margined inter- 
 nally by a black spot; the second near the tip and unmargined. Nearly oppo- 
 site the first costal streak is a large dorsal streak dark margined internally by 
 an oblique black line. Cilia golden around the apex, becoming silvery white 
 toward the tornus. Expanse 6-7 mm. 
 
 The hindwings and cilia are silvery gray. Legs white, first pair shaded with 
 gray. Abdomen dark gray in the male, silvery in the female; anal tuft silvery. 
 
 The mines of this very distinct species are common in the Atlan- 
 tic States on the underside of leaves of Tilia Americana L. The 
 
ANNETTE F. BRAUN. 311 
 
 larva is pale greenish yellow, with a darker head. The mine is 
 rectangular, often nearly square, and placed between two veins and 
 uuwrinkled. When complete, the mine is transparent, and the 
 pupa, which is contained in an oval cocoon, is plainly visible.

 Antennae grayish, broadly annulate with dark brown. Face and palpi shining 
 yellowish white. Tuft reddish golden. 
 
 Thorax and (brewings shining brownish golden. Pale markings shining with 
 a faint golden lustre. There is a short indistinct median basal streak. Just 
 before the middle is a slightly curved fascia, inwardly margined with blackish 
 scales and outwardly shading into the ground color of the wing. At the begin- 
 ning of the cilia is a second fascia, sometimes divided into a costal and an oppo- 
 site dorsal streak by a line of dark scales. Just preceding the dusted apex is a 
 rather indistinct costal streak. Cilia around the apex, of the wing color, becom- 
 ing gray at the tornus. Alar expanse 5.5-6 mm. 
 
 Hindwings and cilia gray. Abdomen gray. Legs shining gray, tarsi spotted 
 with whitish. 
 
 The form described by Frey and Boll is that in which the pair of 
 streaks at the beginning of the cilia do not unite to form a fascia. 
 
 While only reported from Ohio, Kentucky and Texas, its range 
 is probably co-extensive with that of its food plant. 
 
 The larvae form very small tent mines on the underside of leaves 
 of Symphoriearpos Symphoricarpos (L.) MacM. The mine is placed 
 between two veins, and when mature is much wrinkled. Just 
 before pupation, one half of the mine is lined with silk, and par- 
 titioned off, thus forming an ovoid silken chamber in which the 
 pupa is formed. When the imago emerges the pupa case is thrust 
 through the upper epidermis.

 Antennae dark brown. Face and palpi silvery white, with a purplish and 
 golden iridescent lustre. Tuft small, dark brown. Ground color of the thorax 
 and forewings brilliant golden brown ; that of the thorax a shade darker. Two 
 silvery fascise, margined internally with dark brown ; and beyond them two pair 
 of opposite streaks, also internally dark margined, of which the first pair some- 
 times unite to form an interrupted fascia. The basal fourth of the wing is dark 
 brown, more golden below the fold toward the base. The first fascia is at the 
 basal fourth, and shades gradually into the ground color of the wing. It is fol- 
 lowed at about the middle by a second similar fascia. At the beginning of the 
 costal cilia is a silvery spot, and opposite it a larger dorsal spot. At the apical 
 fifth is a similar costal spot, and opposite it a small dorsal one. Marginal scales 
 at the base of the apical cilia dark brown. Cilia silvery gray. Expanse 5.5-6 mm. 
 
 Hindwings and cilia gray. Abdomen dark gray, with a purplish golden lustre. 
 Legs gray. 
 
 The mine is a yellow blotch, occurring upon either the upper or 
 lower surface of leaves of Robinia pseudacacia L. and Robinia his- 
 pida L. The leaf is but slightly contracted and the larva is some- 
 what more flattened than is usual in the cylindrical group. The 
 larva leaves the mine to pupate, spinning a flat, oval, yellowish 
 brown, silken cocoon. 
 
 The species is abundant wherever its food plant occurs.

 Thorax and forewings pale reddish saffron. Three white fasciae, each narrowly 
 margined internally with dark brown scales ; the first at about the basal fourth, 
 the second near the middle. The third midway between the second and the 
 apex, is the narrowest and is slightly angulated in the middle. An indistinct

 mixed with a few white scales. Cilia slightly paler than the ground color. Ex- 
 panse 7-8 mm. 
 
 Hindwings and cilia gray. Abdomen reddish brown. Legs and tarsi whitish ; 
 tarsi slightly tipped with black. 
 
 The larvae form rather large tent mines on the upper side of 
 Ostrya Virginiana (Mill.) Willd. At first the mine is a flat blotch, 
 and the loosened epidermis is white, sparsely speckled with brown. 
 Later, by contraction of the epidermis, the mine becomes roomy

 and ten ti form ; and the leaf is completely folded over. The larva 
 is green and of the cylindrical type, and spins a thin ovoid silken 
 cocoon, fastened to the leaf above and below. Mr. Chambers (Can.

 the mistaken impression that they belonged to his L. virginiella,

 The head, thorax and forewings are of a uniformly dark reddish saffron. Face 
 and palpi shining white, legs whitish gray. The tarsi of the first pair have dis- 
 tinct blackish bands. The second pair are spotted with blackish, the last pair 
 are lighter, marked with brownish black. The dorsal side of the abdomen is 
 dark gray, the ventral side whitish. 
 
 The feebly shining forewings have three fasciae, at the basal third, at the mid- 
 dle, and at three-quarters of the wing length respectively. All the fasciae are 
 faintly dark margined toward the base, the first straight, the second slightly 
 concave, the third feebly angulated. Before the apex there is a white costal 
 streak, without any dark margining. The cilia are of the ground color. 
 
 Hindwings rather dark gray, their cilia lighter brownish. 
 
 Frey and Boll have thus described the species. 
 
 Found in Texas, where the larvae make underside mines on a 
 species of Lonicera, and on" a species of Symphoricarpos. 
 
 The absence of any dark dusting in the apex of the wing distin- 
 guishes the imago of this species from that of tritcenianella Cham.

 The tentiform mine of this species occurs on the lower surface of 
 leaves of Symphoricarpos vulgaris Michx. Pupation takes place 
 within an ovoid white silken cocoon. Mr. Chambers (Gin. Quart.

 "Glistening, snowy white; middle portion of the anterior wings from near 
 their base to the base of the cilia pale golden, which is produced along the costa 
 to the base three broad silvery white fasciae dark margined internally ; the 
 dark margin of the third fascia widely interrupted in the middle, and the pale 
 golden very indistinct, sometimes not visible, behind it; the second fascia is 
 about the middle of the wing. Alar expanse one-fourth inch." 
 
 Chambers has sufficiently characterized this species by the short 
 description above. 
 
 The larvse belong to the cylindrical group and form almost cir- 
 cular tent mines on the upper side of Tilia Americana L. The mine 
 is white, densely speckled with dark brown. The pupa of the sum- 
 mer brood is suspended in a very slight silken web ; in the brood 
 remaining through the winter in the pupal state, a denser cocoon is 
 spun, which is attached above and below. 
 
 The species is common throughout the Atlantic States.

 the cilia on tbfe costal and dorsal margins; the first fascia is situated within one- 
 fourth the wing length, the dorsal portion of it commencing nearer to the base 
 than the costal portion and proceeding obliquely outward to a little above the 
 fold, the shorter costal portion only being conspicuously dark margined inter- 
 nally ; the second fascia, just before the middle, is distinctly curved, almost an- 
 gulated outwards, and has a conspicuous margin of black scales on its inner 
 side; the third fascia, commencing before the costal cilia, is less curved than the

 second, but its black inner margin interrupts it in the middle by a short line of 
 black scales; the fourth fascia, at the apical fifth of the wing, is also internally 
 black margined, but the black scaling is almost interrupted, becoming very slen- 
 der at the middle of the wings; the apical spot is black, encircled by white as 
 already described ; the cilia are grayish, tinged with fuscous about the anal 
 angle, and with a short golden saffron dash from the black apical spot; there is 
 no line along their base. 
 
 Hind wings and cilia pale grayish. Abdomen gray. Hind tarsi whitish,

 Antennae dark brown, narrowly annulate with pale gray. Face and palpi 
 pale golden. Tuft on the vertex reddish orange, with a few brown scales inter- 
 mixed. 
 
 Thorax and forewiugs deep reddish saffron. On the forewings are three 
 faintly indicated narrow whitish fasciae situated at the basal fifth, two fifths,and 
 three-fifths of the wing length, respectively. 
 
 The two former are bent outward above the middle, the third is nearly straight. 
 These fasciae are sparsely dusted internally on the dorsal half with blackish 
 scales, densely so on the costal half, where the margin broadens into a triangular 
 area, that of the first fascia sometimes being produced along the costa to the 
 base. The internal margin of the third fascia interrupts it in the middle with 
 a tooth-like projection. At three-fourths of the wing length on the costa is a 
 patch of dark dusting forming the internal margin of a pale costal streak, oppo- 
 site to which on the dorsal margin above the tornus is a smaller patch of dusting. 
 Just before the apex is a second whitish costal streak, dusted internally with a 
 few dark scales. Apex sparsely dusted with black scales. Cilia of the wing 
 color becoming gray toward the tornus. Alar expanse 8.5-9 mm. 
 
 Hindwings and cilia gray, with a fulvous tinge. Abdomen dark brownish 
 gray, anal tuft with an ocherous tinge. Legs brownish, tarsal joints blackish, 
 tipped with white.

 The following is Chambers' description of the forewings in Can. 
 Ent., vii, 126, 1875 : 
 
 " Thorax and primaries bright golden or saffron yellow, according to the light, 
 or even sometimes dull brownish yellow, the thorax and basal portion of the 
 dorsal margin of the forewings being largely intermixed with white, and dusted 
 more or less with black. Sometimes the inner angle is of the general ground 
 hue, scarcely dusted or marked with either white or dark brown, and then there 
 is a median white basal streak which meets at an acute angle with a dorsal white 
 streak about the basal fourth of the wing length. Both of these white streaks, 
 and all other white markings on the wings are more or less dusted with dark 
 gray-brown, sometimes so much as to obscure the white. Before the middle of 
 the costa is a long white streak, which attains the middle of the wing, curving 
 backwards; a little behind this, on the dorsal margin, is a large dorsal white 
 streak, wide on the margin, but shorter than the first costal streak, like which it 
 curves backwards along the middle of the wing, being usually confluent, or very 
 nearly so with the first costal streak; a little further back, about the middle of 
 the costal margin, is another white costal streak shorter than the first, but like 
 it curving back along the middle of the wing, and usually confluent with the 
 first costal and first dorsal streaks. Then follows another narrower and some- 
 what oblique costal white streak, opposite to which is a triangular white dorsal 
 spot separated from it by some brown scales; just before the cilia is a curved 
 white fascia concave towards the apex and sometimes interrupted in the middle, 
 and just before the apex is another similar fascia, which, however, sometimes 
 does not attain the dorsal margin, and behind it in the apex is a short brown 
 streak. All these white streaks and fasciae are decidedly dark margined before, 
 and more or less dusted with grayish brown. There is a brown hinder marginal 
 line at the base of the cilia, which latter are stramineous." 
 
 Expanse 7-8 mm. 
 
 The hindwings are gray, with ocherous tinged cilia ; pale ocher-

 ous in the summer form. Abdomen gray, with ocherous apex. 
 Legs varying from pale whitish ocherous to gray, their tarsi whitish 
 at the bases, grayish brown toward the apices. 
 
 This species is probably found over the whole of the United 
 States. In the U. S. Nat. Mus. is a series bred by Dr. Dyar at 
 Denver, Colorado, on cotton wood in July, 1901, and a specimen 
 from California on Salix (collection C. V. Kiley). 
 
 The food plants are various species of Salix and Populus, the 
 mine being placed on the lower side of the leaf. The imagoes of 
 the fall brood, which appear in October, hibernate. 
 
 This is an exceedingly variable species, so variable in fact, that 
 specimens of the different broods may easily be mistaken for distinct 
 species. The differences are due to a variation in the extent of the 
 white markings, and in the black dusting, some specimens lacking 
 entirely the black dusting typical of the species. 
 
 I have bred series of this species in successive broods from tenti- 
 form mines on the underside of leaves of Populus balsamifera L. 
 In the imagoes which appear in August, the black dusting is almost 
 or entirely lacking. One of these is represented on Plate XXIII, 
 Fig. 3. Such specimens are identical with those bred by Dr. Dyar 
 in Colorado. In this form the tuft and thorax are often pure white, 
 and very often the first dorsal streak is widely separated from the 
 first costal streak, with which it is usually confluent in the dusted 
 specimens. 
 
 Zeller, in his description of atomariella, and Chambers, in his 
 earlier description (Can. Ent., iii, 163, 1871), regarded white as the 
 ground color of the wings. Zeller's two types at Cambridge are 
 identical with Chambers' specimens, which represent the dusted 
 form of the species (Plate XXIII, Fig. 2). The Zeller type at the 
 U. S. Nat. Mus. (Plate XXIV, Fig. 24) has a greater extent of 
 the wing occupied by the white markings.

 streak, both thickly dusted with blackish scales, and uniting with the first dor-

 sal streak. There are five costal and five dorsal white streaks, all dark margined 
 internally and more or less dusted with blackish scales, the last two pair, how- 
 ever, not dusted. These streaks are situated as follows: a large oblique white 
 costal streak at the basal fifth, attaining the middle of the wing and prolonged 
 backward ; nearer the base an oblique dorsal streak, almost meeting the first 
 costal before the middle; the second costal streak also oblique; the second dorsal 
 streak nearer the base than the second costal, large, oblique, strongly constricted 
 just below the fold, and uniting with the apices of the first and second costal 
 streaks; third costal and dorsal streaks nearly opposite, less oblique, their apices 
 separated by a narrow prolongation of the blackish internal margins. The 
 fourth costal and dorsal streaks, of which the costal is at the apical fourth, the 
 dorsal at the tornus, form an inwardly convex white fascia. Fifth costal and 
 dorsal streaks also form a curved white fascia. An irregular blackish apical 
 spot. Marginal line in the cilia blackish, with a bluish lustre. Cilia gray. Alar 
 expanse 9-10.5 mm. 
 
 Hindwings gray. Cilia gray, with a reddish tinge. Abdomen dark gray 
 above, grayish white beneath. Anal tuft grayish ocherous. Legs dark gray, 
 tips of the tarsi lighter. 
 
 Described from specimens bred by Mr. W. D. Kearfott from 
 tentiform mines on the underside of leaves of Populus tremuloides 
 Michx., received from Mr. J. W. Cockle, Kaslo, B. C., August 26, 
 1907. The imagoes appeared during the same month. The mine 
 is large (for an underside Lithocolletis mine), oval, and with a fine 
 fold through its long axis. It closely resembles the mine of L. 
 salieifoliella on poplar, but is very much larger. 
 
 There is considerable variation in the extent of the white mark- 
 ings ; sometimes the fascia formed by the fourth pair of streaks is 
 interrupted, and the fascia just before the apex does not reach the 
 inner margin. 
 
 This species is very close to L. salieifoliella in the character and 
 arrangement of markings ; but may be distinguished from it by the 
 much greater expanse, the slightly shining and more reddish ground 
 color of the forewings, the slightly less oblique position of the white 
 streaks, and by the noticeable bluish lustre of the marginal line in 
 the cilia. The specimens which appear in August are densely 
 dusted, in this respect differing from the corresponding brood of L. 
 salieifoliella. 
 
 By some mistake, this species has been referred to as Lithocolletis 
 populiella Chambers by Mr. Busck in his paper, " Tineid Moths 
 from British Columbia" (Proc. U. S. Nat. Mus., xxvii, 770, 1904), 
 and by Dr. Harrison G. Dyar in " Lepidoptera of the Kootenai 
 District" (Proc. U. S. Nat. Mus., xxvii, 937, 1904).

 "Face and palpi silvery white, the palpi on their outer surface saffron, flecked 
 with brown. Antennae brown, annulate with white, and flecked with blackish 
 scales. Tuft reddish saffron, with white scales intermixed. Thorax reddish 
 saffron anteriorly, passing into brown toward the apex, sparsely flecked with 
 white, and with the usual white line (sometimes absent), across the anterior mar- 
 gin produced backwards over the tegulse and on to the wings, where it is con- 
 fluent with a narrow median white basal streak which is strongly dark margined 
 dorsally, the dark margin being produced beyond it nearly to the middle of the 
 wing. Anterior wings reddish saffron, the dorsal margin nearly to the cilia, 
 thickly dusted with dark brown on a white ground, and with a streak of dark 
 brown extending to the basal streak not far from the base. Three fasciae, rather 
 indefinitely bounded, of dark brown upon a white ground ; all strongly angula- 
 ted posteriorly about the middle, the third one slightly interrupted near the 
 costa and passing gradually into a costo-apical patch of dark brown on a white 
 ground. The first fascia is just before the middle; the second is about the mid- 
 dle, and each sends a white streak from its angle nearly to the next fascia. 
 There is a dorso-apical patch of dense dark brown dusting on a white ground, 
 larger than the costo-apical one above mentioned. Cilia pale reddish saffron, 
 with a dark brown hinder marginal line in the cilia. Sometimes almost the 
 entire thorax and dorsal margins of the wings are densely dusted with dark 
 brown on a white ground, whilst the first and second fasciae blend with each 
 other near the dorsal margin, and the third fascia blends with the dorso-apical 
 dusting. It varies in the extent and intensity of the dusting. Under surface sil- 
 very white, with a patch of dark brown dusting on each side of of each abdomi- 
 nal segment. Legs silvery white, with the anterior tibiae and tarsi reddish saf- 
 fron, dusted thickly with dark brown, and the intermediate and posterior tibiae 
 and tarsi spotted and annulate with dark brown. Alar expanse one-fourth inch. 
 Kentucky. Not common. The larva is cylindrical, yellowish, and makes a tent 
 mine on the under surface of the leaves of the hackberry (Celtis occidentalis L.)." 
 
 The above extract from the Can. Ent., iii, 128, 1871, is Chambers' 
 original description of the species with his note upon the larval stage. 
 
 There is great variation in the density of the dark dusting ; in 
 one specimen the white fasciae are distinctly present as narrow white 
 lines, beyond what would in this case be considered their internal 
 dusting (the three dark brown fasciae of which Chambers speaks). 
 The first of these fasciae reaches the costa at about the basal third. 
 Often the basal streak is overlaid with black dusting, which then 
 occupies the basal portion of the wing below the fold. This species 
 is much less common than L. eeltisella Chambers, which mines the 
 upper surface of Celtis.

 Chambers records this rare species from Kentucky. I have 
 taken it at Cincinnati, Ohio, and Mr. W. D. Kearfott has collected 
 the mines in the early part of September in Jefferson County, West 
 Virginia. 
 
 The mine, which is of the usual underside type, lies between two 
 veins, and is somewhat variable in shape. The pupa is suspended 
 in a few silken threads. The imagoes appear during the latter part 
 of September.

 This is a name given to a species in the larval state, whose tenti- 
 form mines were found on the underside of Lysimachia lanceolata 
 Walt. (Steironema lanceolatum (Walt) A. Gray). No imago was 
 ever bred. I have never seen a mine of a Lithocolletis on this plant. 
 
 GROUP II. 
 
 The larva of the flat group (Plate XX, Fig. 10) is very much 
 depressed, almost flat, with the sides of the segments projecting, thus 
 giving the entire larva a beaded appearance. The head is flat, 
 somewhat triangular in shape, usually of a shining reddish brown 
 color, with the mouth parts projecting in front. The first three 
 segments of the body are broader than the others ; the body tapers 
 toward the posterior end. While the legs are of the same number 
 and occupy the same position as in the cylindrical larva, all are 
 very rudimentary, appearing as small tubercular projections. Upon 
 the upper and lower side of most and sometimes all of the body seg- 
 ments are distinctly outlined, shining, darker spots the maculae. 
 These vary in shape on the different segments, being elliptical or 
 trapezoidal, but are constant for a given species in each stage. 
 After the seventh or last moult, the larva assumes a more cylindri- 
 cal shape, the legs are better developed, and the dark maculae grad- 
 ually disappear. 
 
 All of the species are miners on the upper side of leaves, where 
 they make a flat, sometimes irregularly shaped blotch, or a rather 
 broad, linear tract. The larva feeds from the centre outwardly, 
 thus gradually increasing the extent of the mined portion of the 
 leaf. This mode of feeding is a necessary accompaniment of the 
 
ANNETTE F. BRAUN. 321 
 
 flattened head, the larva being able to consume but a few layers of 
 parenchyma cells directly in front of it. 
 
 The mine retains its flat blotch-like character until after the sev- 
 enth moult. The larva then lines the loosened epidermis with silk 
 and by contraction produces from one to three narrow folds or 
 ridges. Beneath this folded portion the floor of the mine is thinly 
 covered with silk. Then the larva, lying on its back, spins a flat 
 semi-transparent sheet of silk, oval or nearly circular in shape, 
 attached around its edges to the floor of the mine (Plate XX, 
 Fig. 12). Beneath this, along its long axis, the pupa is formed. 
 The pupa, which is protruded from the mine in emergence, is thrust 
 through a transverse slit near one end of the flat cocoon. Such a 
 cocoon is formed in all but a few of the species of which the life 
 history is known. 
 
 In almost all of the species, however, this cocoon is only made in 
 the brood of which the imagoes are to appear in the same summer. 
 In a later brood, the hibernating period, with one or two exceptions, 
 is passed in the larval state. In a number of species, hibernation 
 takes place beneath the folded epidermis. In most cases, however, 
 an especially prepared silken-lined chamber is formed. After the 
 floor of the mine is loosely covered with silk, the upper epidermis is 
 fastened down in a circular or oval outline, and the whole cavity is 
 then lined with silk. Ample space is provided by a characteristic 
 oval or hemispherical projection upon the underside of the leaf. 
 The change to pupa occurs in the spring. 
 
 The moths of this group may easily be recognized by the fact that 
 the white markings of the forewings are always externally dark 
 margined, often densely dusted with black scales behind. In some 
 cases there is, in addition, a slight internal margin consisting of a 
 few dark scales near the costa. The markings consist of white cos- 
 tal and dorsal streaks, usually oblique. Opposite streaks may unite 
 to form a fascia, either outwardly angulated or straight. Where 
 the fasciae are straight, they are nearer the base on the dorsal mar- 
 gin. The apex of the wing is often densely dusted with black 
 atoms, this effect being produced by the black tips to whitish scales. 
 Sometimes these black tips form a distinct marginal line, which 
 passes around the apex and usually extends to the tornus. This 
 line is always present, but where the apex is not dusted, is not

 length.

 beyond which are one dorsal and two costal streaks ; there is no basal streak ; the 
 first fascia at one-fourth the wing length is but slightly angulated, margined

 This species, of which the above is Clemens' description, is the 
 the common miner on the upper side of hickory in the eastern 
 United States. The mines are irregular blotches ; often two or 
 more mines are confluent. The pupa is formed under an oval 
 silken flat cocoon. The mine occasionally occurs on leaves of wal- 
 nut and butternut. 
 
 Imagoes vary greatly in the distinctness of the fasciae and the 
 dark dusting ; often the first fascia does not extend to the costa. 
 There is a faintly indicated pale basal streak from the inner angle 
 to the fold. 
 
 Alar expanse 6-7 mm.

 Plate XXIII, Fig. 9. 
 
 Antennae grayish, broadly annulate with dark brown. Face and palpi whit- 
 ish, sometimes with a golden tinge. Tuft reddish saffron, mixed with whitish 
 scales behind. 
 
 Thorax and forewings deep reddish saffron. A narrow white line on each 
 side of the thorax is continuous with an indistinct curved whitish basal streak 
 at the inner angle. This streak is sometimes absent, its position being indicated 
 by the few black scales which form its external margin. There are two angu- 
 lated white fasciae, the first at about the basal third, the second at the middle of 
 wing length, both strongly margined externally, and on the costa internally 
 with black scales. The first of these fasciae sometimes consists only of a costal 
 and a dorsal streak, not connected, but of which the black dusting is continuous. 
 At the apical third is a white costal spot, margined on both sides, and beneath 
 with black scales. Beginning a little farther from the base is a long oblique dor- 
 sal streak, strongly margined behind with black scales. Oppo'site its apex is a 
 small white costal spot overlaid with black scales. Apex of the wing densely 
 dusted with black on a whitish ground. A dark brown line runs through the 
 middle of the cilia, which are grayish ocherous, becoming gray toward the tor- 
 nus. Alar expanse 6.5-7 mm. 
 
 Hindwings gray. Cilia gray, with an ocherous tinge. Abdomen dark gray 
 above, pale reddish beneath. Anal tuft reddish. Hind tibiae reddish toward 
 their apices, tarsi white, annulate with black.

 The mine on Ostrya is very characteristic and easily distinguished 
 from that of any other species of the flat group by the numerous 
 longitudinal folds in the loosened epidermis at maturity, causing the 
 opposite halves of the leaf to approach one another.

 Antennse pale ocherous, beyond the basal third annulate with dark; several 
 joints toward the tip dark. Palpi shining white. Face shining white. Tuft 
 whitish, golden toward the sides. 
 
 Thorax and forewings ocherous. A white stripe on each side of the middle 
 of the thorax is continuous with a very oblique curved white streak at the 
 inner angle of the forewing. This streak, which is sometimes dark margined 
 behind, extends to the fold and is usually prolonged along the fold to unite with 
 the first dorsal streak. The first dorsal streak begins at the basal fifth, is oblique 
 and curved, and extends slightly more than halfway across the wing. The sec- 
 ond dorsal streak, at about the middle of the dorsal margin, is also oblique and 
 curved, and near the costa its apex meets that of the first costal streak, which is 
 short, oblique and placed slightly beyond the middle, thus forming an acutely 
 angled, interrupted fascia. The second costal streak at the apical fourth is some- 
 times almost overlaid with black scales. Above the dorsal cilia is a long oblique 
 white streak. All the streaks are dark margined externally. Apical portion 
 white, dusted with black. There is considerable variation in the extent of the 
 black dusting, which sometimes extends to the tornus. Marginal line in the 
 cilia brownish ocherous. Cilia pale ocherous. Alar expanse 5-7 mm. 
 
 'Hindwings pale grayish ocherous. Cilia pale ocherous. Abdomen gray above, 
 pale ocherous below. Anal tuft ocherous. Legs whitish. Hind tarsi faintly 
 tipped with black. 
 
 Described from specimens bred at Cincinnati, Ohio. I also have 
 specimens taken in Essex Co. Park, N. J., by Mr. W. D. Kearfott. 
 
 The mines of this species are very com- 
 mon on sugar maples, Acer saccharum 
 Marsh, and Acer nigrum Michx., as 
 many as 25 or 30 mines sometimes occur- 
 ring on one leaf. The mine is a small 
 irregular blotch on the upper side. The 
 pupa is not enclosed in a cocoon. The 
 imagoes appear from May to June and

 Face, palpi and underside of the antennae white, antennae above annulate with 
 brown ; tuft white, mixed with brown and saffron scales. 
 
 Thorax brownish saffron, with its apex and two longitudinal stripes white. 
 Sometimes almost the entire thorax is white. Forewings brownish saffron, very 
 feebly shining. A broad curved basal streak from the inner margin to the fold 
 is densely dusted behind with blackish scales. Two white fasciae angulated near 
 the costa, one at the basal third, the other at the middle of the wing length ; the 
 dorsal arm of each slightly curved. Each fascia is internally margined by a few 
 black scales near the costal and the dorsal margins. On the outer side the costal 
 arm of each has a few black scales near the costa; the dorsal arm is densely 
 dusted with blackish scales, which are produced backward at the angle. A 
 white costal streak at two-thirds is dusted with blackish scales. Opposite it is 
 an oblique curved dorsal streak, dusted behind with blackish scales, running 
 into the dusted apical portion. Before the apex is a white costal streak with a 
 few black scales before it on the costa. Apical part of the wing dusted with 
 black on a white ground. Hinder marginal line in the cilia brownish, with a 
 few blackish scales intermixed. Cilia around the apex of the wing color, gray- 
 ish toward the tornus. In the cilia, extending outwards from the apex, is a 
 small pencil of dark brown scales. Expanse 8.5-9 mm. 
 
 Hindwings brownish gray, with somewhat lighter cilia. Abdomen in the 
 male dark gray, in the female lighter, somewhat ocherous. Anal tuft ocherous 
 brown. Legs and tarsi whitish, spotted with dark brown. 
 
 This species was originally described by Frey and Boll from 
 specimens from mines on the upperside of leaves of Quercus macro- 
 earpa Michx. in Texas. I have a series of specimens bred by Mr. 
 W. D. Kearfott from blotch mines on the upperside of leaves of 
 chestnut, Montclair, N. J. The density of the black dusting varies 
 somewhat, and in one specimen the basal streak is confluent with 
 the dorsal arm of the first fascia. 
 
 Very close to L. cincinnatiella Chambers, but distinguished from 
 it by the larger size, darker and less shining ground color of the 
 forewings; the more oblique and slightly curved dorsal streaks; and 
 the tuft of dark brown scales in the apical cilia, which is wanting in 
 cincinnatiella. 
 
 The mine of macrocarpella also differs from that of cincinnatiella, 
 being of the usual upperside blotch type and containing but a single 
 larva.

 "Face, palpi, under surface and legs silvery white, the legs marked on their 
 anterior surface with golden and brownish spots and bands: tuft white, golden 
 at the sides; antennae silvery white beneath, above golden brown, faintly annu- 
 late with whitish ; thorax and anterior wings bright golden ; upon the wings is 
 a short snow-white median basal streak strongly dark margined behind and 
 within. (Sometimes the anterior margin and sides of the thorx are also white.) 
 Two snow-white fascise, one at about the basal one-fourth, the other about the 
 middle, both strongly dark margined behind, and sometimes slightly so inte- 
 riorly; and both strongly nngulated posteriorly near the costa; with the first 
 sometimes slightly interrupted at the angle, and the dark margin of the second 
 posteriorly produced. A long oblique snow-white dorsal streak at the base of 
 the dorsal cilia posteriorly dark margined, and a smaller costal one a little behind 
 it at the base of the costal cilia, similarly dark margined. This dorsal streak is 
 sometimes posteriorly produced, and confluent with a straight dorso-apical 
 streak, which is faintly dark margined behind, but is sometimes entirely want- 
 ing. When present it forms the interior border to the apical dusting. Some- 
 times the costal streak is produced so as to be confluent with it also, and opposite 
 to it there is sometimes a costo-apical white spot which is separated from it by 
 the apical dusting, which extends thence to the apex and is black upon a white 
 ground. Hinder marginal line in the cilia dark brown. Cilia golden. Alar 
 expanse one-fourth to one-third inch." 
 
 The species, of which the above is the original description, is 
 common in the eastern United States. 
 
 The larvae form large blotch mines on the upper surface of leaves 
 of white oak, Qaercus alba L. One mine will often contain from 
 several to a dozen larvse. The loosened epidermis is brownish yel- 
 low, somewhat puckered, and often covering nearly the entire leaf.

 basal third and margined internally with dispersed blackish scales, sometimes 
 interrupting it in the middle; the second just behind the middle and margined 
 internally with dispersed scales which are produced in the middle, dividing it 
 into two parts. In the space between the fasciae are a few scattered ocherous 
 scales and an irregular line of blackish scales through the middle. Near the 
 apex is a costal and a dorsal ocherous patch, sometimes meeting, with the space 
 between them and the second fascia more or less marked with a line of irregular 
 dusting, and separated from each other by a more or less dense cloud of dusting, 
 sometimes connected with the produced margining of the second fascia. Apical 
 portion white, mixed with ocherous, and densely dusted with black scales con- 
 nected with the line separating the costal and dorsal ocherous patches. Basal 
 third, of the wing more or less dusted with black and marked with ocherous; a. 
 small patch of black scales on the costa near the base, followed by a black dust- 
 ing sometimes arranged into two irregular bands upon an ocherous ground, of 
 which the more basal one is the broader. Hinder marginal line of blackish 
 scales. Cilia tinged with saffron. Expanse 6.5-8.5 mm., the usual size about 
 8 mm. 
 
 Hindwings and cilia gray, the latter tinged with fulvous. Abdomen gray, 
 with ocherous anal tuft. Legs white, tibiae and tarsi spotted with black. 
 
 Very common throughout the Atlantic States. The larva, which 
 is of the flat type, forms an irregular whitish blotch mine on the 
 upperside of oak, most commonly upon Quercus alba L. While 
 the species is usually confined to oak as the food plant, I have speci- 
 mens bred from Magnolia (District of Columbia) and Ostrya Vir- 
 giniana (Cincinnati), which cannot be separated from those on oak.

 "Antennae white, evenly dotted with brown along their upper sides, the five 
 brown spots towards the apex being larger and more widely separated than the 
 others. Palpi shining white. Face shining white, frontal tuft yellowish in the 
 middle, saffron brown at the sides. Thorax golden saffron, whitish behind. 
 
 " Forewings golden saffron, somewhat shining, a short white patch at the base 
 of the dorsal margin reaches to the fold and is exteriorly dark margined, the 
 dark margin of a somewhat similar white spot on the costal portion of the wing, 
 also reaches to the opposite side of the fold a little beyond it ; at one-fourth the 
 wing length is a waved white fascia running nearly straight from the dorsal 
 margin to the fold, and bulging outwards beneath the costa; this is distinctly 
 dark margined externally throughout and briefly so internally; immediately 
 adjoining the costal margin at half the wing length is a broad, very oblique, 
 white costal streak dark margined on both sides and freely dusted with blackish 
 scales around the apex; the black dusting is continued along the outer side of 
 an opposite less oblique dorsal streak, the apex of which reaches as far as the 
 edge of the costal streak above it; at three-fourths the wing length is a white 
 costal spot slightly margined with blackish atoms, and opposite to this is another

 white dorsal streak, very oblique, externally margined at the apex with dusky 
 atoms, which are continued so as to form a large patch of blackish dusting, at 
 the apex of the wing, on the upper side of which patch lies a sickle-shaped white 
 costal streak, concave towards the costal margin ; cilia pale saffron, with a brown 
 line running through the middle and reaching around the apex nearly to the 
 anal angle, where they become paler, inclining to grayish.

 " Mendocino County, CaL, found and bred in the month of June,

 the upperside of leaves of Umbellularia californica Ntittal ; the pupa 
 being inclosed in a semi-transparent flat oval silken web, within the 
 mine, like that of eincinnatiella Chamb., to which species it is some- 
 what allied. Its nearest ally in America is probably macrocarpella 
 Frey and Boll, but it differs in the possession of a dark margined 
 costa basal spot and in the comparatively straight first fascia." 
 These characters also serve to separate it from eincinnatiella Chamb."

 Lithocolletis agrifolidla Braun, Eut. News, xix, 105, 1908. 
 
 Antennae pale ocherous, spotted with brown above, the last five spots more 
 widely separated. Palpi yellowish white, dark brown externally. Face yellow- 
 ish white. Tuft yellowish in the middle, brown at the sides. Thorax reddish 
 ocherous, with a few dark scales on the patagia. 
 
 Forewings reddish ocherous, somewhat shining. At the basal fourth is a per- 
 pendicular white dorsal streak dark margined externally, and reaching to the 
 fold. A little farther back is a nearly perpendicularly placed white costal streak, 
 convex outwardly beneath the costa and also attaining the fold slightly beyond 
 the dorsal streak ; it is strongly dark margined externally ; its short internal 
 straight dark margin is opposite the external dark margin of the first dorsal 
 streak. Near the base the costal portion of the wing is of a smoky hue. Placed 
 diagonally across the wing toward the base on a line with the internal edging of 
 the first costal streak are two black transverse spots, the first just above the fold, 
 and the second nearer the base just below the fold ; sometimes with a few whit- 
 ish scales internally. At about the middle of the wing length is a broad oblique 
 costal streak, internally dark margined near the costa, and its external dark 
 dusting continued as the external dusting of a much narrower dorsal streak, 
 whose apex just meets that of the costal. At the angle the dusting is very dense 
 on a white ground and is continued backward as a broad band, nearly one-half 
 the breadth of the wing, to a point between the third costal and dorsal streaks. 
 The third costal streak, which is sometimes a spot, not touching the costa, is 
 inwardly oblique, and externally dark margined. Opposite it is a long oblique

 dorsal streak, whose external dark margin is continued into the dusted apex, 
 and which usually unites with a sickle-shaped costal streak lying above the 
 dusted apex, and concave toward the costa. The dark margin of the third costal 
 streak is sometimes continued along the costa to this last streak. Cilia ocherous, 
 with a dark brown hinder marginal line through their middle. Alar expanse 
 7.5-9 mm. 
 
 Hindwings gray, with a bluish metallic lustre. Cilia fulvous. Abdomen dark 
 bluish metallic above in the male, pale yellowish beneath, with a median line 
 and diagonal marks on each segment dark. In the female with the last two or 
 three segments and tuft ocherous, pale ocherous beneath and marked as in the 
 male. Legs whitish, the first two pair annulate with black ; hind tibise shaded 
 with ocherous and black scales, tarsi tipped with black.

 Described from specimens bred from leaves of Quercus agrifolia 
 Nee. received from Mr. G. R. Pilate. The mine is a whitish, some- 
 what irregular blotch on the upperside of the leaf. The pupa is 
 formed under a flat nearly circular semi-transparent web, the upper 
 epidermis, as is usual, being thrown into a longitudinal fold. 
 
 This species is very near to umbellularice Wlsm. The most 
 marked difference is the absence of the costal and dorsal basal white 
 patches characteristic of that species.

 Thorax saffron yellow; head lighter, with whitish face and palpi. Autennse 
 closely annulate with brown, annulations obsolete toward the base. Fore and 
 middle tarsi white, spotted with black ; hind tarsi pure white. Of the size of an 
 average quercifoliella. Forewings dull saffron yellow. On the costa there are 
 two very short oblique streaks and a dot, at one-third, one-half and two-thirds 
 the wing length, all three of a lustreless white color. The two former are exter- 
 nally blackish margined, the second being the longer and dusted around its apex 
 with black scales. A narrow white line extends along the dorsal margin, becom- 
 ing less distinct opposite the first costal streak, beyond which it is almost obso- 
 lete, until it reaches a place between the second costal streak and the costal spot, 
 where it is broadened and deflexed,and extends as the inner margin of the black 
 apical dusting, nearly to the apex of the wing in an outwardly convex line be- 
 coming narrower. uch is the case in but one specimen ; in the second it stops 
 entirely after the broadening, which makes a short streak, and as an indication 
 of its continuation, there is an indistinct dot above the dusting, somewhat behind 
 the costal streak. Toward the dorsal cilia and partly on them is a broad trans- 
 
ANNETTE F. BRAUN. 333 
 
 verse streak, made up of a cloud of black dusting, narrowly separated from the 
 dusting of the second costal streak. Cilia yellowish gray, yellowish around the 
 dusted portion, and without lustre. 
 
 Hindwings gray, their cilia lighter. None of the markings reappear upon the 
 underside of the forewings. 
 
 ID addition to the above description, Zeller has noted another 
 form of this variable species, in which the dusting, especially that 
 in the apical portion, is much less dense. 
 
 Very widely distributed, occurring from New Jersey to Ohio, 
 southward and westward to Texas and California. 
 
 The larvae form blotch mines on the upper side of leaves of vari- 
 ous species of oak. The pupa is formed under a flat, nearly circu- 
 lar silken cocoon. I have a series bred from live oak, Quercus Vir- 
 giniana Mill, from Fortress Monroe, Va., showing all intergrades 
 between specimens having the deflexed dorso-basal streak extending 
 unbroken nearly to the costa, and those in which it is nearly over- 
 laid with black dusting. The figure represents a specimen of the 
 former variety. There is a median white streak on the thorax not 
 mentioned in the description. The character "hind tarsi pure 
 white" is by no means constant or reliable, as several specimens 
 have the first tarsal joint very distinctly tipped with black. 
 
 A series in the National Museum, bred by Mr. Busck on live oak 
 from Willis, Texas, is darker, more densely dusted, and has the 
 antennal joints very distinctly annulate all the way to the base.

 "Face and palpi silvery white, tuft white, intermixed with golden. Antennae 
 silvery white, the apical two-thirds annulate with brownish. Legs and under 
 surface silvery white. Anterior wings bright golden, inclining to orange, with a 
 white streak along the dorsal margin from the base to the cilia, where it is de- 
 flexed and passes on to the dusted portion of the apex which is near the posterior 
 margin, and is dark brown on a white ground. There are three small costal sil- 
 very streaks, the first and second being near the middle of the costal margin, 
 and the second one the largest, while the third is small and near the apex. 
 There is some variation in the size of the third costal streak and in the extent of

 the apical dusting, and sometimes the costal streaks are faintly dark margined. 
 The abdomen and legs are very pale golden varied with white. Alar expanse 
 one-fourth to nearly one-third inch." 
 
 The larvse form irregular blotch mines on the upper side of leaves 
 of elms, Ulmus fulva Michx. and Ulmus Americana L. The pupa 
 of the summer brood is formed under a flat silken cocoon. A later 
 hibernating brood changes from the usual green color to a pale yel- 
 low color, and passes the winter in silk lined chambers. 
 
 The expanse of the imago does not vary as greatly as would 
 appear from Mr. Chambers' measurements, being 6.5-7 mm. The 
 original description, printed above, is accurate in all other details, 
 except that the second costal streak is often more than " faintly 
 dark margined " behind. 
 
 Although resembling L. conglomeratella Zell. very closely, it may 
 be distinguished from it by the uniformly smaller size, paler ground 
 color of the wings, slightly more oblique position of the costal 
 streaks, the absence of the tuft of scales in the apical cilia and 
 especially by the antennae. In ulmella the apical two- thirds only 
 are annulate with brown, while in conglomeratella the annulations 
 are always present for the whole length, although sometimes indis- 
 tinct toward the base.

 Face, palpi, tuft and antennae silvery white; sides of the tuft reddish orange ; 
 each joint of the antennae spotted above with dark brown, the spots becoming 
 small and indistinct toward the base. Thorax and forewings golden ; a median 
 white streak on the thorax is continuous with a dorso-basal white streak on the 
 forewing, which extends slightly beyond the middle of the dorsal margin. Its 
 end is usually bordered with two or three fuscous scales. There are three costal 
 white streaks, of which the first two are oblique. The first at one-third is dark 
 margined behind and sometimes on the costa before ; the second at the middle 
 of the wing length is dark margined behind and around the tip, and the dark 
 scales are produced backward for a short distance. The third is a spot before 
 the cilia dark margined on both sides. Opposite this is an oblique dorsal streak 
 densely margined with blackish scales behind, the dark margin passing into the 
 dusted apical part of the wing. Cilia silvery ocherous; hinder marginal line 
 dark brown. Expanse 6.5-7 mm. 
 
 Hindwings silvery ocherous, cilia concolorous. Abdomen pale yellow. Legs 
 whitish, shaded with ocherous. In the original description Mr. Chambers says 
 " tarsi annulate with black." The fore and middle tarsi are always annulate 
 with black, but more often the hind tarsi are silvery white.

 The species occurs probably throughout the entire eastern half of 
 the United States upon various species of oak. The mine is a flat 
 blotch upon the upperside of the leaf, similar to that of L. conglom- 
 eratella Zell. 
 
 Quercivorella is closely related to ulmella and conglomeratella but 
 may be distinguished from both by the fact that the dorso basal 
 white streak extends only a short distance beyond the middle. The 
 dorsal margin is of the ground color from here to the oblique streak, 
 which occupies the same position as the deflexed portion of the 
 dorso-basal streak in conglomeratella and ulmella.

 Plate XXIII, Fig. 19. 
 
 Antennae whitish, spotted above with brown. Face and palpi white. Tuft 
 whitish, ocherous toward the sides. 
 
 Thorax and forewings reddish ocherous. At the basal third is an oblique 
 white costal streak, black margined externally. A broad white stripe through 
 the middle of the thorax is continuous with a dorso-basal white stripe extending 
 to beyond the middle of the dorsal margin. From its end a white dorsal streak 
 extends obliquely upward uniting in the middle of the wing with a similar cos- 
 tal streak to form a somewhat interrupted angulated fascia of which the external 
 dark dusting at the angle is produced backwards on a white ground for a short 
 distance. At the apical third is a white costal spot, with a few dark scales exter- 
 nally, and opposite it is a long, oblique dorsal streak, dark margined externally 
 and uniting with a curved streak, concave toward the costa, which often extends 
 through the cilia, and forms the internal border to the dusting of the apex, 
 which is black upon a white ground. Cilia ocherous, becoming gray toward the 
 tornus, with a dark ocherous line through their middle. Expanse 7-8.5 mm. 
 
 Hindwings and cilia grayish ocherous. Abdomen grayish ocherous, with pale 
 anal tuft. Legs whitish, shaded with brown ; hind tarsi very faintly tipped 
 with black.

 Closely related to quercivorella Cham., from which it differs, how- 
 ever, by the presence of the oblique dorsal streak at the end of the 
 dorso-basal streak. It is also of somewhat greater expanse.

 " No basal streak nor apical spot on the forewings, which are pale golden (ahout 
 the color of L. argentinotella Clem.). There is no distinct hinder marginal line 
 in the pale yellow cilia. The marks on the wings are: first, a small, white, dor- 
 sal streak ; then an oblique, white costal streak about the basal third of the wing 
 length ; a silvery white fascia about the middle, which is posteriorly angulated 
 nearer to the costal than to the dorsal margin ; a small, silvery white costal spot, 
 immediately before the cilia, and a longer dorsal one opposite to it, extending 
 obliquely backward ; all of these marks are posteriorly dark margined, the dark 
 margin of the last costal and dorsal streaks almost meeting in the apical part of 
 the wing; apex dusted with dark brown on a white ground. Thorax pale golden, 
 with a white streak from its anterior margin to the apex. Head, tuft, palpi and 
 antennge silvery white, each joint of the antennae dotted above with brown, and 
 the basal joint pale golden above. Under surface of body, wings, and legs pale

 begins a long, oblique dorsal streak, which, behind the middle of the wing length, 
 becomes confluent with the second costal streak, and is strongly dark margined 
 behind. There is no basal streak, apical spot, or hinder marginal line. Legs 
 silvery white ; but the first pair of tarsi are marked on their anterior surfaces 
 with fuscous spots. Abdomen silvery white, stained with pale lead color be-

 Lithocolletis platanoidiella Braun, Ent. News, xix, 106, 1908. 
 
 Antennae whitish, banded with brown above. Palpi shining white. Face 
 shining white, with a slight golden lustre. Tuft golden. 
 
 Thorax and forewings deep shining ocherous. Extreme edge of the costa 
 towards the base black. The first costal streak at the basal fourth short, oblique 
 and outwardly dark margined. The second costal streak at the middle of the 
 wing length is also oblique, and its apex meets that of the longer corresponding 
 dorsal streak, which begins at the middle of the dorsal margin, somewhat nearer 
 the base than the costal streak. There is thus formed an interrupted, augulated 
 white fascia, of which the external dark dusting is continuous, and is prolonged 
 backward to the space between the third costal and the second dorsal streaks. 
 These latter streaks are placed opposite to each other, the costal at the apical 
 third, the dorsal at the tornus, and both are dark margined behind. Fourth cos- 
 tal streak somewhat oblique, pointing forwards, and dark margined behind by a 
 few black scales. Apical portion white, dusted with black scales. This dusted 
 portion forms an almost rectangular area. At the base of the costal cilia, but 
 not extending through them, and anterior to the dusted apex, is a small white 
 streak. Marginal line in the cilia brown. Cilia ocherous around the apex, be- 
 -coming gray towards the tornus. Alar expanse 6.5-8 mm. 
 
 Hindwings gray. Cilia gray, tinged with reddish. Abdomen gray above, 
 shining silvery ocherous beneath. Anal tuft ocherous. Front legs dark brown 
 above, with a narrow white stripe beneath. Tarsi white at their bases. Middle 
 and hind legs whitish ocherous, their tarsi tipped with black. 
 
 I have bred this species at Cincinnati, Ohio, from blotch mines 
 on the upper surface of leaves of several species of oak, viz. : Quercus 
 alba L., Quercus macrocarpa Michx., Quercus platanoides (Lam.). 
 The larva is of the flat type, and when mature spins an oval flat 
 cocoon. . The imagoes appear in August. The larvse of the fall 
 brood hibernate in silken lined chambers. There is a specimen in 
 the U. S. Nat. Mus. from New York (Beutenmiiller collection). 
 
 This species superficially resembles L. bethunella Cham., from 
 which it can be distinguished by the absence of the dorsal streak at 
 the basal fourth, and by the presence of two costal streaks beyond 
 the fascia, there being but one such streak in L. bethunella.

 streak and an opposite dorsal streak, both dull white, with a few blackish scales 
 on their outer edges. A group of black scales at the apex of the wing is preceded 
 on the costal and dorsal margins by dull white, not sufficiently conspicuous to 
 be called costal and dorsal streaks; cilia grayish, their bases tinged with saffron, 
 a slender blackish line along their middle, passing round the apex.

 Face and palpi snow-white; tuft saffron yellow. The antennae whitish gray, 
 annulate with brown, attain an unusual length. They fully equal the length of 
 the forewings. Thorax saffron ; legs whitish, with unspotted tarsi. Abdomen 
 dark gray, light underneath. 
 
 The moderately shining forewings have a true saffron color. They show the 
 following shining silvery white markings; on the costa at one-third of the wing 
 length there is a rather small, obliquely placed costal streak, imperfectly mar- 
 gined toward the base with a few black scales. The corresponding dorsal streak 
 is short, blunt, not well developed, placed at the basal fourth of the wing length, 
 and is externally more strongly margined with blackish scales. Then follows, 
 about in'^the middle of the wing, an angulated, interrupted fascia, inwardly 
 blackish margined, and with a shorter costal and a longer dorsal arm. At three- 
 quarters of the wing length is a pair of streaks, the dorsal placed at the hind 
 angle. The trace of a last costal streak appears just before the apex. The black 
 dusting extends in considerable breadth from the above-mentioned pair of 
 streaks to the hind margin, either in the shape of a broad spot, or to the unaided 
 eye as a dot suddenly ending. Base of the cilia saffron, tips whitish gray. At 
 the hind angle they become entirely of a uniform light gray. 
 
 Hindwings and cilia gray. The underside of the forewings dark ocherous gray.

 The description given above is a translation of that by Frey and 
 Boll, and appears to be somewhat inconsistent in several details. 
 While it seems to belong to the flat group of larvae, the internal 
 dark margin of the fascia, if the description is correct, is an 
 anomaly in the group. I have seen no specimen of the species, 
 and it is impossible to determine its position with certainty. It 
 was described from specimens bred from upperside mines on a 
 species of Carya in Texas, and is one of the smaller species.

 "Face and palpi silvery white; antennae silvery white beneath, brownish 
 banded with white above; tuft golden,. interspersed with white; thorax and 
 anterior wings reddish orange, with three costal and three dorsal silvery streaks, 
 all dark margined externally. First costal and first dorsal small, the dorsal 
 being the largest and nearer to the base, whilst the costal is a little oblique and 
 at about the basal one-third of the wing. The second dorsal and second costal 
 about the middle, opposite each other, and a little oblique, the dorsal being the 
 longest, and almost meeting the costal near the costa, whilst their dark margins 
 do meet and are posteriorly angulated and produced to the space between the 
 third dorsal and third costal. The third dorsal and third costal are a little 
 behind the apical one-third, opposite, straight, and the dorsal is the longest. 
 Apex dusted with blackish on a white ground. Cilia fulvous, with a dark brown 
 hinder marginal line at their base. Al. ex. a little over one-fourth inch." 
 
 The above is Chambers' original description. As noted by Cham- 
 bers, the opposite costal and dorsal streaks (except the first pair) 
 are sometimes confluent, forming fasciae. There is also, just before 
 the apical black dusting, a small white spot, which does not extend 
 through the cilia. Alar expanse 6.5-7.5 mm. 
 
 The larvae, of the flat type, form oval blotch mines on the upper 
 side of several species of oak, and spin flat, oval, silken cocoons. 
 The species occurs in the eastern half of the United States, west and 
 south to Texas. 
 
 The description of lebertella Frey and Boll in no way differs from 
 that of bethunella, and their life history is identical. The synonomy, 
 as above given, will doubtless stand, although there has been no 
 opportunity of comparing specimens of bethunella with the type of 
 lebertella in England.

 The external margining is in the males more distinct and of a

 scarcely darker than the ground color. 
 
 The upperside mines occur on several species of oak : Quercus 
 rubra L., Quercus alba L., Quercus acuminata (Michx.) Sarg. The 
 mine is a rather broad Y-shaped tract, sometimes crossing the mid- 
 rib. The flat, oval, silken- cocoon is spun in the leg of the Y. 
 Specimens bred from such mines are in every respect identical with 
 Clemens' type of obstrictella. Dr. Clemens was certainly in error 
 when he described the mine of obstrictella as a mine on the under- 
 side of oak leaves. The imago of this species is typically that of 
 the flat larval group. 
 
 Obstrictella may be distinguished from all other allied eastern 
 species by the character of the black scales which form the apical 
 dusting. These scales are more freely tipped with black than is 
 usual in the case of the scales forming the apical dusting of the flat 
 group, and hence the effect is a large black spot rather than a num- 
 ber of small dots. The silvery scales before the apex are also char- 
 acteristic of the species. 
 
 Chambers' type of bifasciella is identical with Clemens' type of 
 obstrictella; on one wing the third fascia is nearly complete. 
 
 The specimen from which Lord Walsingham described ceriferce 
 is identical with the series of specimens of obstrictella from the 
 Beutenmiiller collection in the U. S. Nat. Mus. All of this series 
 bear the breeding record number 114 (blotch mine on the upperside 
 of red and white oaks). The type of ceriferce is the only specimen 
 bearing on the pin the food plant label, " Myrica cerifera." This is 
 certainly an error.

 Thorax and forewings reddish ocherous. A short white streak from the inner 
 angle to the fold dark margined externally. Two white fasciae dark margined 
 externally ; the first at about the basal fourth, oblique, nearer the base on the

 nearly erect. At the apical fourth is a white costal streak, and opposite it a 
 nearly erect dorsal streak above the cilia; both are dark margined externally. 
 In the apical portion of the wing is an oblique white streak, not extending 
 through the costal cilia, dusted with fuscous scales behind and around its apex. 
 This dusting is sometimes almost lacking. Hinder marginal line in the cilia

 silken chamber in which the larva hibernates is of the usual type, 
 the epidermis not being raised in a circular ridge as in ostryarella. 
 
 The male specimen which Lord Walsingham described as bifas- 
 eiella Cham, is one of the series from the Beutenmuller collection, 
 bearing the record number 118, and bred on Corylus, and identical 
 with specimens of corylisella Cham.

 Thorax and forewings reddish ocherous. A white streak from the inner angle 
 to the fold, faintly black margined externally. Two white fasciae, the first begin- 
 ning on the dorsum at about the basal fourth, concave outwardly on the fold, 
 thence extending obliquely to the costa, which it reaches at about the basal third. 
 It is black margined externally. The second fascia, at about the middle, is 
 slightly oblique and black margined externally. At the apical fourth a costal 
 white streak black margined externally. Opposite it above the cilia is a very 
 oblique, long dorsal streak also black margined externally. Just before the apex 
 an oblique white streak on the line of the last dorsal, and not extending through 
 the cilia, is dusted behind with blackish scales. The scales in the apical third 
 of the wing are tipped with brown. Hinder marginal line in the cilia brownish. 
 Cilia ocherous, grayish toward the torntis. Expanse 6-7 mm. 
 
 Hindwings grayish ocherous. Cilia grayish, tinged with ocherous. Abdomen 
 gray, tuft ocherous. Legs whitish ocherous, hind tarsi sometimes tipped with black. 
 
 The larvae form irregular blotch mines on the upperside of Ostrya 
 Virginiana (Mill.) Willd. and Carpinus Caroliniana Walt. ; as 
 many as four or five sometimes occurring in one mine. The hiber- 
 nating larva? pass the winter in circular silken-lined chambers, the 
 outline appearing on the upper epidermis as a circular narrow 
 ridge ; a convex projection appears on the lower sid. 
 
 The brownish dusting of the apical third of the wing is the dis- 
 tinguishing characteristic of ostryarella. Corylisella may also be 
 distinguished from ostryarella by the dorsal streak above the cilia 
 being nearly erect, while in ostryarella it is oblique and nearly 
 parallel to the edge. The fascise, especially the first, are also less 
 oblique in corylisella.

 "Front silvery, tuft reddish orange and silvery mixed. Thorax reddish 
 orange. Forewings reddish orange, somewhat metallic, with a white streak, 
 black margined exteriorly, from the inner basal angle to the fold ; with two 
 oblique silvery bands, black margined behind, one about the middle of the wing 
 and the other midway between it and the base of the wing. Near the tip is a 
 costal silvery spot, black margined behind, with an opposite, oblique dorsal streak 
 of the same hue, likewise black margined behind, and an oblique costal silvery 
 streak continued on the line of the last dorsal, running into the cilia just before 
 the tip, black margined above, at the tip before, and below at the tip behind ; 
 scarcely with a hinder marginal line, cilia of the general hue. Hind wings plum- 
 beous, cilia with a fulvous hue. 
 
 " The larva mines the leaf of maple in September. It mines the upper surface 
 of the leaf, making a flat, rather broad tract, casting its frass along the middle of 
 the course of it.' Physical characteristics those of the second larval group. Head 
 pale brown ; body yellowish green, with oval, dorsal, brown maculse, darkest 
 on their margins; thoracic rings on their sides pale yellowish. The cocoon is 
 circular." 
 
 The above is Clemens' description and represents the typical 
 eastern form of the species. Specimens occur in which the white 
 streak at the base of the dorsal margin is replaced by a pale ocher- 
 ous shade, bordered externally by brown scales. The dorsal streak 
 above the cilia is also very variable, being in some specimens almost 
 erect, while in others it is oblique and parallel to the termen. The 
 usual expanse is about 7 mm., but specimens collected at Ottawa, 
 Canada, by Mr. C. H. Young expand 8-9 mm. Iri these specimens 
 the pale streak at the base of the wings is scarcely lighter than the 
 
 ground color. 
 
 The mine is common throughout 
 the Atlantic States on leaves of 
 red maple, Acer rubrum L., but is 
 rarely found upon sugar maple.

 Syn. hamamelis Smith's List Lep. Bor. Am., 1903, No. 6844. 
 
 Face and palpi whitish. Antennae whitish ocherous, annulate with dark brown. 
 Tuft reddish orange. 
 
 Thorax and forewings deep reddish orange. An oblique white streak from the 
 inner angle to the fold is black margined externally. There are two straight, 
 oblique, parallel, silvery bands black margined externally, the first at the basal 
 fourth, and the second at the middle of the wing length. At the beginning of 
 the costal cilia is a silvery spot, black margined externally. Opposite it is a long, 
 very oblique dorsal streak, parallel to the termen, also black margined behind, 
 and uniting in the apex of the wing with a short apical streak, dark margined 
 at its apex and above and below. Marginal line in the cilia of the wing color. 
 Cilia reddish, becoming gray at the tornus. Expanse 7 mm. 
 
 Hindwings and cilia reddish gray. Abdomen dark gray above, ocherous gray 
 beneath. Legs pale brownish red, tarsal joints white, tipped with black. 
 
 This species is distributed throughout the Atlantic States wherever 
 the food plant, Hamamelis Virginiana L. (witch hazel), occurs. The 
 mine is a whitish blotch, sometimes almost circular; the pupa of the 
 summer brood is formed beneath a flat silken cocoon. 
 
 Although it is very closely related to aceriella, it may be separa- 
 ted from that species by the deeper and more reddish color of the 
 tuft and wings, and by the more distinct marginal line in the cilia. 
 The hind tarsi of hamameliella are also very distinctly tipped with 
 black, whereas, in aceriella, they are either faintly blackish tipped 
 or entirely pure white. The oblique dorsal streak, which has been 
 used to separate hamameliella from aceriella, cannot be relied upon, 
 as this streak is often as oblique in aceriella as in hamameliella.

 "The larva belongs to the second larval group of this genus, but the body is 
 much more contracted than that of any other larva I have seen. Its form is 
 almost that of a flattened ovoid, the rings separated by the deep incisions, and 
 each forming in the sides a projecting mammilla.

 "The larva mines the upper surface of the leaves of oaks in September, and 
 doubtless also in tbe summer months. The mine is a linear tract, sometimes 
 curved or wavy, gradually increasing in breadth from the beginning to the end, 
 or, as the larva increases in length, with the frass deposited on each side of the 
 tract, and marking its outline by two black lines. The position of the larva 
 within the mine is likewise a peculiar one, as it is always placed transversely to 
 its course, and hence the deposition of the frass on the sides, and the gradual 
 increase in breadth, as the larva grows in length. Its head is blackish-brown ; 
 the body pale greenish, with pale brown dorsal maculae, darker on their edges. 
 It undergoes transformation in the end of the mine, preparing a circular cell or 
 slightly silk-lined cavity, and leaves the last larval cast outside of it. The fall 
 brood of larvse become imagoes about the middle of May." 
 
 The above is Clemens' complete description of the species. 
 
 The very characteristic mine can- 
 not be mistaken for that of any other 
 species. The mine is often branched, 
 the larva returning toward the begin- 
 ning of the mine, and starting out 
 anew in another direction. 
 
 In the apex of the wing, there is 
 sometimes a minute white spot, with a

 Originally described by Clemens as above from specimens from 
 tentiform mines on the underside of Desmodium viridiflorum L. It 
 has since been bred from mines on several allied plants, among 
 them Lespedeza capitata Michx. and Phaseolus pauciflorus Benth. 
 
 Frey and Boll (Stett. ent. Zeit., xxxvii, 227, 1876) made note of 
 the peculiar enlarged appearance of the apical third of the forewings. 
 
 The specimens described as gregariella were bred from large infla- 
 ted mines on the underside of Phaseolus pauciflorus Benth., a num- 
 ber of imagoes emerging from one mine. In all other respects, ex- 
 cept the gregarious larval habits, these are identical with desmodiella. 
 
 However, in a series bred by Mr. August Busck from similar 
 mines on Desmodium at Washington, D. C., all of the specimens 
 were noticeably smaller, the largest expanding but 3 mm., and 
 almost all lacked any indication of the white costal streak before 
 the cilia (Plate XXIV, Fig. 15). 
 
 On various species of Lespedeza, where both the gregarious and 
 solitary larval habit is exhibited on the same plant, I have bred 
 both varieties from the same mine. 
 
 CREMASTOBOMBYCIA,* new subgenus. 
 
 Cremastobombycia differs from Lithocolletis proper in the follow- 
 ing characteristics : terminal joint of the labial palpi a little longer ; 
 vein 5 of the forewings present, 5 and 6 stalked, vein 6 of the hind 
 wings present, 5 and 6 long stalked (Plate XX, Figs. 6, 7), some- 
 times borne on an independent stalk to near the base, where this 
 stalk is short stalked with the upper median vein. The stalk is 
 obsolete from the middle to the end of the cell (Plate XX, Fig. 6). 
 
 Larva cylindrical, without prolegs on 10, usually pale greenish or 
 yellowish becoming darker at maturity. All of the species, as far 
 as known, are miners in the leaves of various species of Composite, 
 the mines being found upon the lower side of the leaf, except that of

 grindeliella Wlsm., which is also sometimes an upperside miner. The 
 loosened epidermis is very much wrinkled longitudinally at maturity. 
 
 The species of this subgenus pupate in an elongate, dense, white 
 cocoon (Plate XX, Fig. 13), sometimes ornamented with longitudi- 
 nal ridges. This cocoon is suspended inside the mine by two slightly 
 diverging silken threads at the posterior end, and by either one or 
 two threads at the anterior end. 
 
 The markings of the forewings consist of a more or less distinctly 
 developed basal streak ; four white costal streaks, and two or three 
 dorsal streaks. There may be one or two more or less distinctly 
 angulated fasciae, formed by the confluence of opposite streaks. 
 
 The species herein included represent a more ancestral type, more 
 nearly related to the Gracilaria group of genera. 
 
 One species, solidaginis Frey and Boll, is found from the Atlantic 
 to the Pacific ; the other species have a more limited range. 
 
 The species may be separated by the following table : 
 
 A. Basal streak distinct, reaching almost to or beyond the basal fourth. 
 
 B. With an angulated fascia at one-fourth grindeliella. 
 
 BB. Without a fascia at one-fourth. 
 
 C. Basal streak narrow, pointed, unmargined solidaginis. 
 
 CC. Basal streak much dilated posteriorly ainbrosiella. 
 
 AA. Basal streak minute or wanting. 
 
 B. Markings with a brilliant silver lustre; costal and dorsal streaks at three- 
 fourths never confluent ignota. 
 
 BB. Markings not so brilliant; an angulated fascia at three-fourths.

 very indistinct, at about equal distances apart, the first and second of which are 
 outwardly oblique and are met at a somewhat acute angle on the middle of the 
 wing by two even less distinct dorsal streaks, faintly dark margined externally ; 
 the third is a mere spot, opposite which is a small spot at the base of the cilia at 
 the anal angle; immediately preceding the apex is a conspicuous curved white 
 costal spot divided from a smaller and less conspicuous one below it by the 
 cloudy streak of black scales which runs to the apex ; cilia with a ferruginous 
 tinge, becoming gray at and within the anal angle, and having a few black scales 
 below the apex.

 "Hind wings and cilia gray. Abdomen dull gray; anal tuft pale. Legs whit-

 With the exception of the omission of any mention of the basal 
 streak, which is confluent with the first fascia just below the fold, 
 the above description by Lord Walsingham is that of the typical 
 form of the species, in which the first fascia attains the dorsal mar- 
 gin. In another variety (Fig. 22, Plate XXIV), the first fascia 
 ends abruptly just below its angle and does not unite with the basal 
 streak. All gradations exist between these two varieties. 
 
 The species was originally described from a specimen from Ala- 
 meda Co. ; I have bred a large series from Mariu Co., California. 
 
 The mines occur upon either the upper or lower surface of leaves 
 of Grindelia robusta. In the upperside mines the leaf is more con- 
 tracted and the epidermis is thrown into more distinct folds than is 
 the case in the lower side mines. The elongate white silken cocoon 
 is attached at its posterior end by two fine threads, and at its ante- 
 rior end by a rather broad band of silk.

 Antennae grayish, distinctly annulate with dark brown. Face and palpi yel- 
 lowish white. Tuft brownish ocherous, white at the sides. Thorax and fore- 
 wings reddish ocherous; a white stripe on each side of the thorax continuous 
 with a rather indistinct whitish basal streak on the forewings below the fold, 
 ending at one-third. Four white costal streaks, of which the first two are oblique, 
 and situated at one-third and at the middle of the wing length respectively. The 
 third is at two-thirds, and nearly perpendicular and the fourth just before the 
 apex and inwardly oblique. All are dark margined externally with dark brown, 
 the margin of the last forming the dusting of the apex. A long, oblique dorsal 
 streak commences near the middle of the dorsal margin ; its dark margin usually 
 unites with that of the second costal ; sometimes the streaks themselves unite. 
 Opposite the third costal an oblique dorsal streak is indicated by a slightly 
 lighter shade and a few dark scales behind it. Hinder marginal line in the cilia 
 brownish, rather indistinct. Cilia ocherous. Alar expanse 7-9 mm. 
 
 Hindwings and cilia ocherous gray. Abdomen gray ; anal tuft ocherous. Legs 
 whitish, banded with ocherous; tarsal joints tipped with black. 
 
 A common species in the United States, making elongate, much

 dago. The dense white cocoon, marked with longitudinal ridges, is

 Antennge gray, annulate with dark brown. Face and palpi whitish, sometimes 
 with a deep blue-gray metallic lustre. 
 
 Thorax and forewings reddish saffron. A fine white line on each side of the 
 thorax is continuous with a short basal streak broadening toward the end, where 
 it is faintly dark margined. At the basal fourth is an oblique white costal 
 streak, dark margined externally. Very rarely there is a minute white spot on 
 the dorsal margin, with a few black scales behind it. About the middle is a 
 white fascia, sometimes angulated, margined with black behind and with a 
 slightly darker shade before. At the beginning of the cilia there is a white cos- 
 tal streak and a slightly oblique dorsal one opposite, both dark margined behind 
 and faintly so before. Just before the apex is a curved white streak, sometimes 
 attaining the dorsal margin, with a few dark scales behind it in the apex of the 
 wing. Cilia of the wing color, grayish toward thetornus. Expanse 5.5-6.5 mm. 
 Hindwings gray, cilia with a fulvous tinge. Abdomen gray, somewhat metal- 
 lic, tuft tinged with ocherous. Legs fuscous, tarsi white, broadly annulate with 
 black. 
 
 Widely distributed in the east, also occurring as far south and 
 west as Texas (Boll). The larvae mine the leaves of Ambrosia trifida 
 L. and Ambrosia artemisiaefolia (L.) Britton, and of Verbesina alter- 
 nifolia (L.) Britton (Actinomeris squarrosa Nutt.). The mine is very 
 small, placed upon the under suface, and is not visisble on the upper- 
 side as an inflated swelling, as is that of ignota. The dense white 
 fusiform cocoon, suspended hammock-like in the mine, has a smooth 
 surface, lacking entirely the longitudinal ridges characteristic of that 
 of ignota. 
 
 Easily distinguished from ignota in its early stages, the imagoes 
 may be distinguished from that species by the broad white basal 
 streak, which in the form described by Frey and Boll as amcena, 
 attains the dorsal margin ; by the absence of the brilliant silvery 
 lustre of the white markings. Amcena lacks the dark margins pres- 
 ent on the type of ambrosiella. Bred specimens show great varia-

 Antennae brownish gray, annulate with darker. Face and palpi pale golden. 
 
 Tuft reddish saffron, intermixed with white. 
 
 Thorax and forewings deep reddish saffron. A fine white line on each side of 
 the thorax is continuous with a very indistinct snd short basal silvery streak 
 beneath the fold, consisting of a few scales. At the basal fourth of the wing is 
 an oblique silvery costal streak, black margined externally, and sometimes on 
 the costa before; rarely entirely unmargined. On the dorsal margin, slightly 
 nearer the base, is .a small dorsal spot, sometimes represented by but two or three 
 silvery scales, rarely margined behind with one or two dark scales. At the mid- 
 dle of the wing is a silvery fascia, varying from nearly straight to acutely angled. 
 In the former case the fascia is broader, strongly margined externally and on 
 the costa before with black. In those specimens having a distinctly angulated 
 fascia, the fascia is narrower, sometimes interrupted at the angle, its external 
 black margin less distinct, and usually not dark margined internally. At the 
 apical third are two opposite rather large, perpendicularly placed silvery streaks, 
 black margined behind, and the costal one sometimes on the costa before. Just 
 before the apex is an outwardly concave silvery costal streak, sometimes attain- 
 ing the dorsal margin, and sometimes with a few black scales before. Behind it, 
 in the apical portion of the wing, are a few black scales. Cilia slightly paler 
 than the wing color, shading to gray toward the tornus. Expanse 6.5-7.5 mm. 
 
 Hind wings and cilia brownish gray, the latter with a purplish lustre. Abdo- 
 men above dark brown, with a metallic lustre. Legs fuscous, all the tarsi annu- 
 late with black. 
 
 Widely distributed, occurring from Massachusetts to Texas, and 
 feeding on various species of Com positsc. Among its recorded food 
 plants are Verbesina alternifolia (L.) Britton (=Actmomeris squar- 
 rosa Nutt.), Elephantopus Carolinianus Willd. and Verbesina Vir- 
 ginica L. These three are the food plants recorded by Boll from 
 Texas. Mr. August Busck bred the species from Elephantopus 
 Carolinianus Willd., at Washington, D. C., and Mr. Chambers on 
 Helianthus giganteus L. from Kentucky. 
 
 The rather large tentiform mine occurs on the lower surface of 
 the leaf. The loosened epidermis becomes much wrinkled in the

 later stages, and the mine is distinctly visible on the upper surface 
 as a tubercular swelling. The larva, which is pale in the earlier 
 stages, becomes dark brown just before pupation. The dense white 
 elongate cocoon, ornamented with longitudinal ridges, is suspended 
 in the mine at each end by two silken threads. 
 
 The series of specimens from which the above description was 
 made were bred from mines on Verbesina alternifolia (L.) Britton 
 at Cincinnati, Ohio. Frey's description of actmomeridis is applica- 
 ble to those specimens having the straighter fascia, and heavier 
 margins of the silvery marks. A specimen bred by Mr. August 
 Busck on Elephantopus Carolinianus Willd. is identical with these. 
 The description of elephantopodella agrees with those specimens 
 having the angulated fascia, and narrower and less distinctly dark 
 margined silvery marks. Frey has described ignota as having un- 
 spotted hind tarsi ; in none of my series is this true. This variation 
 in the markings of the tarsi occurs frequently, and cannot be con- 
 sidered of specific value. Chambers' types of helianthivorella all 
 have the hind tarsi distinctly annulate with black, show considera- 
 ble variation in the angulation of the silvery fascia, and have the 
 minute basal streak.

 "Antennae silvery white* with black annulations, last four or five joints white. 
 Labial palpi silvery white. Face golden iridescent white; tuft on head reddish 
 yellow, with a few white scales. Thorax and forewing deep golden yellowish 
 brown. At basal third is a silvery white costal streak directed outward, strongly 
 margined externally with black. At the middle of the wing is a silvery white, 
 outwardly angulated fascia, and at the beginning of costal cilia another similar 
 one, both strongly margined externally with black. Just before apex is a third 
 small silvery white fascia with a few scattered black scales externally. Cilia 
 light golden yellow. Hindwings dark silvery gray, cilia a shade lighter. Abdo- 
 men above dark gray; underside silvery and golden yellow. Legs silvery, with 
 broad black annulations. Alar expanse 6.4 mm." 
 
 Described as above by Mr. August Busck from a single specimen 
 bred from Verbesina Virginica, collected at Palm Beach, Florida, 
 by Dr. Dyar. 
 
 Mr. Busck has given the following note upon the early stages : 
 " The larva makes a roomy tent-shaped mine on the underside with 
 the lower epidermis much wrinkled longitudinally, and pupates in 
 an elongate white cocoon suspended at both ends like a hammock 
 inside the mine. Larva belongs to the cylindrical group."
