Goleopterological Notices, VI. 775 



The male sexual characters are extraordinarilj' developed, and 

 affect principally the entire surface of the abdomen and the pos- 

 terior legs. The basal segment of the abdomen is impressed and 

 more densely pubescent near each side of the bod}', apparently 

 in both sexes. The pronotum is evenly convex, not at all im- 

 pressed at any point, and is narrowed in front. The epistomal 

 suture is ver}^ coarse and deep. The thi-ee species known to me 

 ma}^ be recognized as follows : — 



Short pubescence of the elytra not forming a median fascia but more or less 

 condensed along the suture. 



Front very densely punctate and granulose; epistoraa densely pubescent; 

 eyes separated by their own width; body large and stout... 1. priiiceps 



Front sparsely punctate and with scattered minute, acutely elevated gran- 

 ules; epistoma smooth, with a few remote and feeble granules ; eyes much 

 more aj)proximate on the vertex, separated by scarcely three-fourths of 



their own width ; body smaller and narrower 3. basalis 



Short and pale pubescence forming a faint zigzag median fascia and an apical 



spot; last antenual joint elongate and bent, at least in the male; eyes still 



more narrowly separated 3. iiebulosus 



The elytral punctures in this genus are not only coarse but 

 Tery deep, and their floors are flat and highly polished. 



1. E. princeps n. sp. — Oblong, convex, dull, brownish-black throughout, 

 the tarsi, palpi aud base of the elytra, more broadly at the sides, pale testa- 

 ceous; pubescence short, moderately dense, the short hairs strongly condensed 

 along the elytral suture. Head wider than long, thick, convex, very densely 

 punctate and granulose, the antennaj thick, fully two-fifths as long as the 

 body, gradually incrassate from the third joint, the joints feebly obconical, 

 separated and perfoliate, transverse toward apex, the eleventh oblique and not 

 quite as long as the preceding two together. Prothorax distinctly narrower 

 than the head, a little wider than long; sides parallel and nearly straight in 

 basal half, then strongly convergent to the arcuate apex, which is scarcely 

 more than two-thirds as wide as the base, the latter very feebly arcuate; disk 

 evenly, moderately convex, densely sculptured like the head, each puncture 

 with an attached setiferous tubercle. Scutellum large, triangular, narrowly 

 truncate at apex. Elytra two-thirds longer than wide, not quite twice as wide 

 as the prothorax, parallel and nearly straight throughout at the sides, broadly 

 but evenly rounded at apex, the humeri narrowly rounded, well exposed at 

 base; disk feebly impressed at each side of the suture throughout the length, 

 also feebly so within the humeri, the punctures very coarse, deep and dense. 

 Abdomen finely, moderately closely punctate, finely pubescent, the legs com- 

 paratively short, not very stout. Length 3.0 mm. ; width 1.25 mm.
