The Graspedosomatidse of North America. *79 



The triangular ej^es, dark color and larger size indicate that this 

 species has more characters in common with Conotyla than with 

 Trichopeialam, thongh when males are found it is likely to prove 

 distinct from both genera. 



We examined the type specimen, TJ. S. Nat. Museum Xo. 440, 

 and made the following notes : — 



Eyes (fig. 101) triangular, the ocelli in diagonal rows beginning posteriorly 

 1+6 + 5 f 3+1^16. Three ocelli border on the lateral margin of the head. 



First segment with posterior margin convex, otherwise as in C. fischeri. 



Subsequent segments with the median bristles longer than the exterior ones, 

 at least on posterior segments. The tubercle on which the interior bristle is 

 located is just mesad of the much swollen carina. An elevated ridge runs 

 above both the exterior tubercles. Segments of the middle of the body short, 

 bristles rather close together, the median pair located well ahead. Anterior 

 subsegments with four or five rows of small, oblong elevations set close to- 

 gether. The usual median furrows and ridge jjresent, but faint. On the pos- 

 terior segments the carinse gradually disappear, and the protuberances tend to 

 become arranged in a straight line. 



Penultimate segment equal in length to the antepenultimate. 



Anal segment contracted posteriorly, viewed from above it appears squarely 

 truncate. The usual eight bristles present. 



Anal valves not prominent, margins scarcely raised; above slightly exceed- 

 ing last segment, and faintly angled; each with three bristles, the superior one 

 close to the apex of the anal segment. 



In September 1893 two female specimens of a species bearing 

 a general resemblance to wijandotte were collected in a swampy 

 pasture at Grass Lake, near Jackson, Michigan. 



Habitat: Known only from the vicinity of Bloomington, 

 Indiana.
