 genus of Curculionida' exceeds it in the nundjer of its representatives in 

 the American Tcrtiaries; no less than ei;^ht species are roiiiid in Florissant 

 alone, and two in the Gosiute fauna; no species is I'oinid in i)otli. 'I'ln- 

 species found in our western 'I'ertiaries are abundant and vary somewhat 

 in size and stoutness. They agree in having' circular or nearl)' circular 

 eyes, which are not approximate above, aWdoininal segments of etjual or 

 subequal length, a punctureil ])rothorax, and jjunctato-striate elytra, the in- 

 terspaces also usuall}' punctate. In very few are the antennae jjreserxed, 

 and when they are they overlie otherpartsorareotherwi.se obscure, so that 

 it can only be said that they closely resemble in general appeai'ance the 

 living forms, but whether the funicle is in any case six or seven-jointed 

 can not be determined with certainty.
