REVISION OF ELEODIINI BLAISDELL. 375 



General observations. — The mentum is small and more acute at 

 apex than in other species; the surface is rather strongly convex at 

 middle, finely and not strongly punctured, not noticeably setose. 



The prosternum is variable. Feebly widened or subparallel be- 

 hind the coxa\ more or less arcuate antero-posteriorly, frequently 

 subtruncate behind or feebly nuicronate; surface usually distinctly 

 grooved at middle. 



Mesosternum vertically arcuate or obliquely declivous, and more or 

 less distinctly concave. 



The metasternum laterally between the cox;r is as long as the widtli 

 of a metatibia at apex. 



The abdominal process is quadrate (male) or slightly transverse 

 (female) and a fifth (male) to a fourth (female) of its width broader 

 than the metasternal salient, subequal in length to the second segment 

 (male) or equal to that of the post-coxal portion of the first segment 

 (female). 



In the male the post-coxal part of the first segment is a little shorter 

 than the process and about a half longer than the fourth. 



In the female the second segment is about twice as long as the 

 fourth. 



The protarsi are about two-fifths (male) or a half (female) of 

 their length shorter than a mesotarsus. 



The mesotarsi are about a seventh (male) of their length shorter 

 or subequal (female) to a metatarsus. 



The metatarsi are about a fourth (male) or about two-thirds 

 (female) of their length shorter than a metatilna.

Suboblong-ovate, somewhat robust, shining, about twice as long as 

 wide; pronotum transverse and with reri/ short erect setae laterally 

 on the disc and propleura\ 



Head twice as wide as long, feebly convex, usually impressed lat- 

 erally and along the frontal suture, the latter more or less evident, 

 coarsely and irregularly punctate, frequently with impunctate areas 

 on the frons and vertex, punctures crowded laterally and on the epis- 

 toma. Antenna' moderate in length and stoutness, outer three or four 

 joints slightly compressed and noticeably dilated, third joint about 

 equal in length to the next two coml)iiied, fourth and fifth subequal, 

 sixth and seventh apparently just the least shorter and subequal, 

 eighth a little shorter, broader, and subtriangular, ninth and tenth 

 transversely oval, eleventh ovate, apparently broader than long.
