4. PHRUDOPAMERA gen. nov. {gjpovdo?, Pamera, nom. gen.). 



Head rounded, of about equal length and breadth, rather broader than 

 the apex of the thorax, more or less produced in front of the antennfe; eyes 

 situated at the outermost limits of the head, a little in advance of the base, 

 of moderate size, subglobular ; antennae as long as the head, thorax, and 

 scutellum together, the basal joint barely or not surpassing the front of the 

 head, the three succeeding joints subequal, the last incrassated so as to be 

 half as broad again as the middle of the second joint. Thorax scarcely 

 longer than the head, half as broad again as long, tapering forward from 

 the posterior limit of the anterior lobe, the sides ampliated ; posterior mar- 

 gin truncate or slightly convex, the anterior margin similarly concave. 

 Legs moderately stout, the middle femora not more than two-thii'ds the 

 width of the body at their insertion. Abdomen moderately full, well 

 rounded. 



Two species occur in the shales of Florissant.
