XIV. Catorama Guer. 1850. (Gr\, ' ' downward + to view. ") 



A large genus of small, broadly to narrowly oval, convex species, 

 clothed above and below with short appressed pubescence. An- 

 tenna? 10-jointed; first joint larger, second much smaller, obconic; 

 third to seventh very small, about as long as wide; eighth large, 

 triangular, as long as the six preceding united; ninth similar to but 

 slightly smaller than eighth; tenth longer, oval. Thorax evenly 

 convex; moderately strongly curved each side at middle, sinuate 

 each side, front angles acute, hind ones broadly rounded; elytra 

 irregularly punctate, usually with two marginal stria? extending 

 from middle to apex, one or both of these often lacking. Meta- 

 sternal process produced into a stout acuminate hook, curved back- 

 ward and clasped by the mandibles in repose ; first ventral segment 

 excavated for the reception of the hind feet and nearly concealed 

 by them; segments 2-4 decreasing a little in length, the fifth longer. 

 Seven species have been taken in Indiana, while three additional 

 ones may occur.
