-the preceding, globular ; tenth still slightly thicker, not quite as long as -wide ; 

 eleventh slightly broader than the tenth, gradually, acutely pointed but not 

 obviously oblique at apes, not quite as long as the two preceding. Prothorax 

 about as long as wide and y^ wider than the head, feebly narrowed at base, 

 broadly rounded anteriorly, the transverse impression distinct and crossed by 

 a fine but distinct carina near each side but not in the middle ; fovese ob\'ious. 

 Elytra % longer than wide, only slightly more than twice as long as the pro- 

 thorax and about twice as wide, widest but little before the middle, where the 

 sides are rather more strongly arcuate ; humeral plica long and strong, the 

 subhumeral impression large, elongate and deep ; fovese approximate and 

 deep ; subsutural impressions obsolete, the suture strongly beaded subbasally, 

 the bead rather gradually expanded toward the basal margin. Legs well de- 

 veloped, the femora quite strongly clavate, the posterior only just visibly less 

 so. Length 1.25-1.45 mm. ; width 0.55-0.6 mm.

The male, which serves as the type of the above description, 

 has the secondar}^ modifications of the third and fourth segments 

 rather feeble, the former having two very small subapical denti- 

 form projections, separated bj^ scarcely more than a tenth of the 

 total width, the latter with a short suberect dense comb of 

 spicules having the same lateral extent and limited at each end 

 by a very minute corneous tooth much shorter than the spicules. 

 The female is a little larger and slightly more ventricose, with 

 rather shorter antennae, but does not differ otherwise. 



4. E. varicornis n. sp. — Somewhat ventricose, polished and impunc- 

 -tate, black, the elytra dull and translucent rufous ; legs blackish, the tarsi and 

 basal parts of the tibise pale ; antennae pale testaceous, the outer five joints 

 T)lackish ; pubescence sparse but coarse, pale, rather long and suberect on the 

 elytra, shorter and less sparse on the head, abundant and stiff on the prothorax. 

 Head orbicular, not quite as long as wide, the eyes moderate in size and not 

 prominent ; clypeus simple, with the usual short transverse sulcus at base. 

 AntennaB moderately slender and scarcely more than % ^s long as the body, 

 the club rather strong and distinctly incrassate ; second joint about as long as 

 the first but thinner, feebly obconical, twice as long as wide, shorter than the 

 next two and distinctly thicker ; three to six equal in width, feebly obconical; 

 third and fifth subequal, barely }4, fourth I4', sixth }^ longer than wide ; 

 seventh much thicker, suboval, narrowed at base, % thicker than -the sixth, 

 % longer than wide ; eighth distinctly shorter and % wider than the seventh, 

 scarcely }^ longer than wide ; ninth nearly }<^ thicker than the preceding, sub- 

 globular, as long as wide ; tenth scarcely visibly thicker, oval, not quite as 

 long as wide ; eleventh elongate, very gradually pointed, almost as long as the 

 two preceding and distinctly thicker. Prothorax as long as wide and ^4 wider 

 iihan the head ; sides parallel and broadly arcuate, sinuate toward base ; trans- 

 verse impression feeble at the middle, crossed near each side by a fine carina
