'Tliis genus, abundantly represented in Kurope, ratlier feebly in Amer- 

 ica, where it is found in the United States, and ;ir high elevations in Cen- 

 tral America, seems to have lived at Florissant, a couple of species, one of 

 them tolerably common being found there; yet they certainly differ from 

 modern types in the brevity of the antenna- and blnntness of the head, 

 and are considerably slenderer than anv American species known to me. 

 They may be placed here at least provisionally.

Head triangular, rounded, slightly broader than long, the ungulate

 second joint longest, the .succeeding joints successively shorter. Thorax 

 with convex sides, the anterior about three-fourths the length of the poste- 

 rior border, the former slightly concave, the latter as slightly convex, tin- 

 surface faintly punctate, though this does not appear on all individuals 

 Hemelytra with the corinm reaching the middle of the abdomen, strongly 

 infuscated with pallid markings, consisting of a broad, pale subcostal stripe 

 which does not reach the membranal suture, and a median triangular patch 

 seated on the same suture, besides which a pale, slender stripe follows the 

 sntura clavi. Abdomen full and rounded.
