The Graspedosomatidse of North America. 7*1 



N. M. No. 3; Truitt's Cave, No. 234; Neal's Cave, No. 235; 

 Coon's Cave, Nos. 236 and 443; also Nos. 419 and 447, with no 

 locality given. McNeill's types were from Mayfield's Cave, five 

 miles northwest of Bloomington. The species is reported by 

 BoUman from all the above localities and from Phitt's and Done- 

 hue's Caves, Bedford, Indiana, and said to be abundant. 



Conotyla leilbergi sp. n. 



Plate VI, figures 102-104. 



Eyes svibtriangiilar, the posterior dorsal side straight, other sides curved, 

 beginning at posterior dorsal side arranged 9-)-6-|-5+3+l=24, the first row 

 with two small ocelli. 



Antennse subclavate, length 1.7 mm., 6th joint thickest, .16 mm. in diam- 

 eter; ratio of lengths of joints, beginning with the seventh, 2: 4: 7: 6.5: 10: 

 5:5. 



Gnathochilarium differing from that of the three preceding species in the 

 possession of a small, broadly triangular promentum. 



First segment anteriorly nearly semicircular, posteriorly slightly emargin- 

 ate, margined anteriorly to the lateral angles; a fine dorsal line posteriorly; 

 the three tubercles located as in C. fischeri. 



Subsequent segments with gradually swollen carinoe of moderate size, pro- 

 portionally not so large and abruptly elevated as in C fischeri. The lines 

 and reticulations as in that species, but more pronounced. 



Anal segment broadly truncate, more so than in C. fischeri. Bristles ar- 

 ranged as in that species. 



Anal valves subequal to anal segment, the angle more pronounced than in 

 C. fischeri; moderately convex, margined, with three bristles, arranged as in 

 C. fischeri. 



Anal scale small, nearly semicircular; two tubercles, with long setae ap- 

 pressed to the anal valves. 



Color: Dorsum dark fuscous-brown, nearly black, a fine median line, a line 

 along the tubercles, the ventral portions, feet and extremities of the body 

 paler, horn-brown or sordid. Antenn£e dark brown. On some paler speci- 

 mens the darker color of the posterior subsegments gives the appearance of a 

 series of transverse dark bands and a row of dark spots along the sides. 



The carinae of this species are proportionally not so large and abruptly ele- 

 vated as in C. fischeri. 



Length 14 mm. ; width 1.4 mm. 



Habitat: Lake Pend d'Oreille, Idaho. 



We have examined three female specimens collected on " dry 

 granite ledges, in tufts of moss." The material was sent us by 

 Mr. J. B. Leiberg, for whom we take pleasure in naming this 

 species.
