44. Cryptemra nemwa. Brown ; fourteen pairs of legs, the posterior pairs 

 verv long ; antenna nearly as long as the body , large segments gibbose, rounded 

 beliinrl, scutifbrm, sides notched i tail having two filaments as long as the body j 

 length over one inch— Found by Mr. Hayden in the cellars of Baltimore: seg 

 2ti< nts longer than broad. 



VIII. N. G. Stskomeha Differs from Crj/ptomera by narrow segments visible 

 not covered; the first segment is a narrow one; head oval, antenna setaceous, 

 thick and ar. proximated at the base.— Very near to Cryptomera : the name means 

 barrow parts. 



45. Stetiomera interrupt a. Antenna twice the length of the head; fourteen 

 pairs or l< gs, the post* riorones longer and thicker; sides deeply notched, tail bi- 

 dentate— I have found it near Hadley's, falls (in 1816) on the Hudson river, on 

 mushrooms, upon which it feeds probably. Length one and an half inches; co- 

 lour pule brown ; many of the large segments are slightly lunulate behind, all arc 

 bro Met than long. 



IX. X. V. MrcoTiiritKs Differs from Cryptomera by all the segments equal and 

 apparent, and head of various shapes, eyes lateral when visible, Etc. — This genus 

 differs from Julua by having only one pair of legs to each segment. The name 

 implies feeding on mushrooms, as most of the species do. There are many of? 

 them in the United States. I shall merely mention three at present. 



46. JMjyfotherea Ob'gopoda. Antenna one-third of total length, bent outwards; 

 head rounded ; bodj attenuated behind ; seven pairs of equal legs ; ta.il bifid. — 

 Found on the Luzerne mountains of New York, near filen's falls. Length one- 

 fourth of an inch, colour fulvous. It may be the type of a sub-genus, Erocerc. 



47. Mycotheres teitceputla, Antenna straight, one-fifth of total length ; head 

 truncate body linear, fulvous, about twenty pairs of white legs, the posterior one", 

 rather longer ; tail bisetose. Found in the knobs of Kcnt'y. length less than 1 inch. 



48. Jllrcoih r s trittata. Fulvous, a longitudinal brown streak on the hack ; an- 

 tenna momuform, longer than the head ; about fifty pairs of legs, almost equal ; 

 tail elongate oblu.se, with a lateral setaceous appendage on each side ; head oval, 

 pandurati , obtuse : eyes lateral, visible, round. — A. fine species about two inches 

 long and one-twelfth broad. It may form a sub-genus Neimpleura. Found in 

 (he highlands of New York. The antenna have about fifteen rounded articles. 

 Eyes black, almost inferior. The head and tail are not streaked.. 



X S. G. PLBunoLOHA. Body oblong, convex above, unable to contract into a 

 globe ; many narrow segments, the mid lie ones larger, each with a marginal scale 

 on each side and common!) two pairs of ventral legs, with four articles and a cili- 

 ated claw ; the first segment or neck nearly concealed and without scales or feet. 

 Head short ; antenna lateral moniliform, with six oblong articles, — A fine genus 

 next to Glomeris : the name me*ns lateral margin. Hind legs shorter as in all tin. 

 following three genera. 



4'.'. Pleurolomtijlavipes. Antenna grey, one-fifth of the body ; head brown, 



transversely oblong ; eyes black, back blackish shining, marginal scales reddish, 



eighteen segments and only thirty pairs of legs; bell), legs and tail yellow, tail

"-. I V f, N'jri rub. Body cylindrical, with many narrow segments, each with 



two pairs of geminate legs, except tile anterior segments which have only one 



pair. Head obln s with a visible neck; eyes anterior irregular ; antenna lateral 



he head, recurved behind in a lateral groove, with six depres- 



.-tirlas, the second longer, the last globular. Legs with four articles and a

bcncr.th.— Next XoJuhtt : the name is mythological. 



Blackish brown, ninety pairs of feet, pale purple ; the 



nts with a single pair ; (ail obtuse, split beneath ; length about 



- II is found in the woods of Kentucky. Winn handled it dves the
