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." The 

 disi'overy of a se«*ond sj>e<ies of Pauropoda in America was announ<'ed 

 in 1S7S, by Dr. John A. liyder, and in ISTO a third, forminu tlie new 

 jicnus KuryimuropuH: the same author also published (ISSl) a list of 

 the Lysi<>pefnU(l(F, addinj; a new jjenus and species, Zyyon<>pun whitei. 

 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. Kohlrausch, in ISHl, i)ublished his '"(rattunjicn und 

 Arten der Scolopendrideii," in which all the known species of this fam- 

 ily are <lescribe<l. Two Anierican species of Scolopetulra were described, 

 which had been briefly characterized in a preliminary paper published 

 in 187S. 



Three papers were i)ublished by Dr. Packard in 18.S3; the first was 

 a description of I*oly<ksmu» occJIntuH (afterwards referred to Craspedo- 

 soma hy Stuxberji); the second was a revision of the Lysiopetalida', 

 ffiving; a summary of the known information to date and describing 

 the new jjenus CryptotrUhus; the third was a mori)holofiical paper on 

 the appendages and mouth i)arts of the Myriapotla. 



In 18S4 Dr. Latzel ])nblished a valuable monograph of the Myriapoda 

 of Austro-IIungary in which a few notes are given on the American 

 species of the so-called Lysiopetalida*, most of which he referred to the 

 Chordeumidie; the work contains synopses of all the genera of Myria- 

 poda and a very complete bibliography of the subject, containing 611 

 titles. Dr. Meinert, of Coi)enhagen, published in 1.S.S4 an account of 

 the Chilopoda of the Museum of Comparative Zoology, describing 

 fifteen new species from the United States; and the year following 

 appeared the third part of his "Myria])oda Musa'i Ilauniensis," in 

 which two species of Liihohius were added to our fauna. 



In J^ovember, 1885, L. M. Underwood published a review of the 

 principal literature on the American si)ecies, with synoptic tables of 

 genca and a summary of the group as known to him; at that time, 

 however, some minor papers were overlooked, so that the summary 

 given should be somewhat increased. Twenty-seven genera with one 

 hundred and twenty nine species were recorded.* A subsequent paper 



*The <;eograi»hic distribution of the species as described Tip to that time is pecu- 

 liar. The State having the hirgest number was California, with 27; then followed 

 Pennsylvania, 25; Hlinois, 16; CJeorgia, 13; Oregon, 12; Virginia, 10; Texas, «; 

 New York, 7; and Florida, 7; all others falling below 5; 15 had no described 

 sjieeies. The report of Indiana with onlj' two species may have incited Mr. BoU- 

 mau to his study of local forms, which commenced soon after.
