In this species the prothorax is evidently less convex than in 

 most of its allies (e.g., creher, Blackb., gravicollis, Blackb.) 

 which may be readily seen if specimens be looked at from in 

 front, and which moreover causes the pronotnm viewed from 

 the side to appear not so high from the lower to the upper 

 (as sesn from that point of view) outline as in creher, etc.

This species is distinguishable among its immediate allies 

 by the hind angles of its prothorax entirely rounded off, in 

 combination with comparatively strong and not very close 

 puncturation of its pronotum, which is about as close and 

 fine as — but a little stronger than — the corresponding sculp- 

 ture in the species which I regard (and which stands generally 

 in collections) as Sericesthis ( MelolontliaJ 'pruinosa, Dalm. I 

 am in some doubt of the sex of the specimens before me, but 

 am disposed to think them males on account of the compara- 

 tive stoutness of the tarsi, which are certainly more slender in 

 some specimens of at least one allied species.
