Coleopfera, Part II.

to him, nevertheless referred them all to Chlamydopsis, and in this 

 I was content to follow him. But, as the species are now rather 

 numerous, and are certainly allied together in clusters, it seems 

 desirable to propose several new generic names for some of them; 

 as it is certain that other entomologists will not be satisfied to leave 

 them all in the typical genus. I therefore purpose apportiijning 

 them as follows : — 



Orectoscelis. 

 This genus is unknown to me. To it Mr. Lewis referred humeralis 

 and duhoulayi : also, somewhat doubtfully, sternalis. The last 

 named species, liowevei', I pui'pose transferring to Plieidoliphila. 



CItlami/dopsis. 



Regarding striatella as the type of the genus, the species may 

 all be distinguished by the prothoracic margins being narrowly, 

 usually unevenly, raised in front, and frequently at the sides. The 

 elytra are widely depressed near the base, with the depression ex- 

 tending to the sides, but towards the margins concealed by raised 

 humeral processes. Of these some species have each shoulder in the 

 form of an epaulette, Avith two projections behind it; others have 

 the epaulettes split into two projections, which almost meet two 

 subhumeral ones, the raised parts having fascicles or pilose mem- 

 branes. Hind legs, more or less elongate, and not entirely fitted 

 into grooves. 



To this group comata and tuberculata are now referred as 

 aberrant species, for which, at present at least, it is not desirable 

 to propose new generic names.
