iNTRonncTORY Note.
Tlio I'ollowinjjj revision has owuiiicd all tho tiino which I njukl curi-
veiiiently spare f'roiu uiy professional duties tor the past four inoiiths, and
has involved more labor than \ anticipate d. My design was u, lmvc de-
scriptions and H<.'ures, — drawn as carefully as )Missil)le from the insects
themselves. — of every species known to our fauna, not oidy in order to
facilitate the identification of cabinet specimens, but to sliow as plainly as
possible the wonderful and very varied structures to be met with in this
•rroup of fienera. I trust that my objects have been accomplished with
at leasi partial success.
The descriptions of nenera have for the irreater part been drawn from
Lacordaire's (rcnera des Coleopt^res, with such additions and adaptations
a.s were found necessary for our species. The jreneral scope of the family
is that triven in the classification of the Col. of N. A. by Drs. ficOonte
and Horn. Tiie synonymy of Iltini/iip/iis has been drawn from Dr.
Horn's paper on that subject. The position of the genus X<irf/irrii(s at
the head of the Cucujinae was first proposed by Mr. Crotch in some
unpublished manuscript notes; the same distinguislied entomologist also
recommends the fusion of SifroiiKs and Xmixiftins. but I think uiuieces-
sarily.
I have to give my most sincere thanks to Drs. Le(\)nte and Horn, as
well as to Mr. E. A. Schwarz for the utdimited use of their cabinets and
libraries.
As is well known it has long been a disputed (piestion whether the Sil-
vaninae pn^perly form a part of the Cucujidae or Cryptophagidae, but as
the group possesses characttirs common to both and, as it were, forms a
connecting link between them, it is a matter of very little importance to
which family we attach it. The differential characters, however, do not
appear to me to be sufficiently important to warrant us in considering
them a distinct family.
As at present organized, therefore, we have the following general
characters :

hind, separated hy the prostcriuini.
.Mesosti'rniim moderate, sometimes the portion lietween the middle

Anterior coxae variahle in size and sometimes closely ajtproximate —

triaiiiiular. I'osterior coxai- transverse, nearly conti<:-uous
JiC^s rather short, femora lariic tihiae slender, terminated hy two
s|iurs. 'i'arsi very variahle. soiucliiues heteromeroiis in the males, and
pcniamerous in the females. iis\ially with the first joint small, and pen-
tamerous in hoth sexes.
The family is comp(tsed of a comparatively iarii(' luimtier of genera,
which, as may he seen from the ahove analysis, are very heteroiicneous
in niauv respects, hut which jirescrve in common, except in Sifnnnts. a
certain licneral fucits. The species are irenerally flat and eioiij>ated ;
sometimes excessively so. and of a somhre tint. They are found L;(>n<>rally
under hark, and are usually moderate in tluiir movements, idthou^h
Trlt'ithdiiiiH rrto.r runs with the most remarkahle swiftness.

This species mtiy be distinguished from tlu^ preceding by its partly
shining surface, thiit of the former being of perfect opacity, without a
trail- of lustre. The prothorax is much wider, with more imperfectly
developed teetii, and with the sides much less sinuous. Less punctured,
slightly smaller, and lighter colored specimens of this species from the
Pacific Sloj)e were niimed S. iii(i</iiliis, by Dr. LtK'onte, but I hardly
think there is a doubt tis to their identity with j>/(iii((/ii:i. Locality in the

Differs from the European )ii(ni(/if/ii/iiriii in the followinnj particulars :
The mandibles are much longer, and tin; anteiiniic are less roliust than
in that species; the color of our species is deeper, smd tlie prothorax has
a well-marked median furrow which does not appear — from the single
specimen which I have had under examination — to be developed in the
first. But it is in thejugtihir pii'ces that the greatest diff"erenc(! exists,
those of our .species being very long, slender, and attaining the tips of
the mandibles, while in the Kuropean species these plates do not approach
the tips within one-fourth of their length.
Howtiver, with till these differences, which nuist be admitted to be of
minor value. I can only regard (niirrirniKi ,> a variety of minnUhiilnris,
[f the genus contained a liirge nundier of species, the above differences
might be regarded as specific, but in the present cii.se tiiere is but one
form known, and as the tv o races resemble each other so closely we are
warranted in a.ssuming iiiat these differences are only those due to local
influence.

As til the tarsi of this genus, sonic (lirterencc of opinion has been ex-
jirt'sscd. Kriehson niaintaininu' a tivc-joiiitcd tarsus with the lirst joint
small. Duval disseeted the tarsus and found four joints oidy. with the
first joint liilolied. On I'iate l\' will he found a representation of the
middle tarsus of our species as it apjiears to the writer under a power of
about fifty diameters; and I am inclined to agree with Krichson and
Laeordaire as to its five-joiiiied nature, both from analogy and ap-
pearance.
.Siili-family III.— CUCL'J1>.'AH
The chief point of distinction between this sub-family and the preced-
ing, is the absence of tlur corneous plates concealing the maxillae, these
,>;ing rejilaced by small projections not separated from the otlier portions
of the under surface by a sutur(^ Two tribes are indicated in our fauna

This sinf:;ular species was phiced hy LeContc in his genus Pnrdiulrita,
})iit tlicre is apj)arontly no valid reason for such separation. The reason
given in the classification, viz. ; the emargination of the labruni, will not
liold good, a.s thi.s is a peculiarity of many other specic^s acknowledged to
he genuine Liimojtfilai. It belongs ])rohiibly to the .same group mh
Wolliiston's (ixilfdris, from Miideira, and is still more closely allied to
Grouvelle's aipito from Mexico.
It seems to be (piite rare in collections; one specimen (Horn) — tliree
specimens (LeConte) — all from Southern California.

well marked; sides nearly straight; lateral striae moderately distinct; surface
covered sparingly with ])ubescence. Elytra a litth^ longer than the head and pro-
thorax together, of same width as the latter; entire and evenly rounded behind.
Metasternum very long, so that the abdomen is hardly one-half the length of the
elytra. Abdomiual segments sub-equal, the first u little longer than the others.
AnlenuHe short, slightly longer than the prothorax, first joint moderate; joints

It has usuidly been acccpteil as a fact that IIi'tnijHjilii.'i belongs to the

must therefore be with the general cliiiractei.>< of the ('iicujidai' on the

We have therefore two jrcneral and two special sexual characters, the

XoTK.— Lest some aniliiguity iriay be apparent in the use of the term "mar-
gined" as used with reference to the protliorax in the preceding pages, it mav be
stated that in all my writings it will be iimler.stood to mean that the protliorax is
limited laterally by a narrow surface, which is usually raised, but which in some
eases may be continuous in elevation with the gentTal surface and limited inter-
nally by a striated or grooved line.
Again when the term " edge" is employed in describing the pronotum. it will
have reference to the boundaries of that part when considering the vertical cross-
section, and the jihrase would then road "edges acute." or "edges rounded."
When the term " side" is sp.iketi of, it w'U relate lo thecimfortnation of the lateral
boundary of the pronotum with reference to its nature as a- line, this line being the
horizontal projection of the boundary as seen when viewed i)erpendicularlv, and
the i)liraseology to be employed will be "sides arcuate, straight or sinuate," or
various modifications of these terms.
These matters are brought uj) at this time in < rder, if possible, to render the
phraseology a little more concise and uniform. A striking example of this want
of uniformity, is seen in the use of the term " margined." Dr. Sharp using the
word as defined above, while one or two of our leading coleoj)terists have u.sed it
to indicate that the edges of the pronotum are a;ute. which is evidently an abnor-
mal use, and one. the meaning of which, would be decidcilly unintelligible to a
person not familiar with this particular employment, however well-versed he
might be with its usual signification as an English word.
In the case of Narthen'ii.i, as defined in the tabic i>t' gene-'a composing Grouj) I
of the Cucujinue, the expression " jirotliorax margined," has reference to the sur-
face included between the lateral striae and the sides of the pronotum, and per-
haps it would be less ambiguous to say in this case that the prothorax is striated
in Xartherius and not slr;ate<l in Pedianis, because of the comparatively great
distance between these striae and the sides in the former genus.
