I.. M. «\I)KU\Vublished iu an appendix to the Eeport of Marcy's Exploring Expedition a description of Scolopindm hcros^the large "centipede" of the Southwest, with plate, together with two species of Juliiii supposed to be new. Three years later Sager published brief and indetinite de- scriptions of three new species, giving neither distinguishing characters to his species nor the localities from which he obtained his specimens. The lirst four decades since Say's first publication thus found us with a known Myriapod fauna of about thirty nominal species. *An alphabetic list of the literature relating to the Aiiieriean species is appended to this lutrodiii'tiou. 9 10 BULLETIN 46, UNITED STATES NATIONAL MUSEUM. In 18r»0 an extonsivo monofjraph of the Mexican ^Iyriapo I7iiited States and other jmrtions of America. This was soon followed (1803) by Koch's elaborate work, "Die Myria- poden," in which he described and ii^aired fifteen species from the United Stfites. Dr. H. C. Wood pnblished a series of papers from 18(51 to 18G7 which to this time are the most extensive series pnblished by a sinus families of the Diplopoda, and the next year his "Myriapoda of Xorth America," in whi(;h he described all the species then known to inhabit this country, comprising eighteen genera and ninety-two species. Two brief supplementary papers appeared in 1867 on sundry new species from California and Texas respectively.* A monograph of TAt hob ins by Ludwig Koch appeared in 1802, containing two species from the United States. During the years from 1809 to 187U E. D. Cope published, in three papers, descriptions of several (;ave myriai)ods, including the new genera Fseu^otrcmia, Anclrofpuifhus, Pctftserpcs, and Scolerpen. Hum- bert and Saussure published "Myriapoda Xova Americana" in 1869, which contains only Mexican species, many of which are likely, how- ever, to appear on our Arizonian borders when the Myriapod life of that region shall be studied. In 1870 Dr. Packard noted tin; discovery of Pauropus in Massachusetts, the first appearance of the order Pauro- poda in America. In the same and the following year Meinert desci ibed two species from New Orleans in his "Myriapoda Mus.Ti Hauniensis," I, II. In 1872 Oscar Harger descTibed a number of species with the new genus Trk'hopetahtm. During the same year the sixth part of the "Mission Scientifique au Mexique" appeared, consisting of De Saussure's elaborated ''Etudes sur les Myriapodes. In this work several species from the United States are described, and a very complete catalogue of all the described species from the American continent is appended. In Hayden's Geo- logical Survey of the Territories, Annual for 1873, Dr. Packard gives some notes on the Myriapods of Colorado, and describes, without assign- ing names, several new forms. In 1887 he described Pohfdesmus cavi- cola^ a cave-inhabiting species from T'tah. The travels in this country of Gustaf Eisen led to the collection of various groups of animal forms, besides the Vermes, in which he was particularly interested. The species of Lithohius collected by him were described by Dr. Stuxberg in 1875, amounting to seven species. Two *A8 Dr. Wood nowhere mentions the -^vork of either Panssnre or Koch it is more than probable that they were unknown to him. This is still more evident from the synonyms which have resulted. THE MYRIArODA OK NORTH AMERICA. 11 otlior papors, "G«Mieiii <'t species Tiitliobioidanim'' and " Lithohioidsr Anu'iicii' Iloiealis,*' were i)ubIisluHl by the same author t'roiu Stockholm the same year. These jiapers are vahiable from their full synonoiuy and notes on distribution. A translation of tlie latter pjiper was pub- lished in vol. VII of the Proeeedinjjs of the California Academy of Sciences. In 1S77 IlrnchyvyUe rosea, from (.'aliforn'a, was described by Andrew Murray in his volume oil ''Economic Entomolofry."

In ISSO Dr. Karsch, of Berlin, published three papers on the various families of I)ii»lop« ■ .. in \^hich six new spe<'ies from the United States are described.

To this genus have been referred our larger species of so-called Jiilns; from the latter genus it is easily separated by the number of man- dibulary combs, by the second pair of legs, and tlie tirst pair of the male. This genus is divisible into the following subgenera: *Male: Pnmi<*ntmii very large, ovate, nairowiiijn the lingual ]»lates; lirst segment enlarged, sides very broad, almost subriuadrate; first pair of feet very large, crassate, curving inwards and erossing each other, armed with numerous tuber- cles on the inner side, moderately pilose P.xka.ulus i. ** Promentum and first segment same size in both sexes; first pair of feet of male small, stumpy, crassate and straight, tubercles absent, sparsely pilose.
