pression long, very deep and conspicuous ; fovese small and very approximate ; 

 subsutural impressions obsolete ; suture feebly beaded for some distance basally, 

 the bead gradually slightly wider toward base. Legs moderate, the femora 

 feebly clavate, the anterior pair more strongly. Length 0.9 mm.; width 

 0.45 mm.

This species is allied quite closely to fatuus, as indeed are all 

 the species of this subgenus, but may be distinguished at once by 

 the strongly inflated hind body, much paler antennal club, slightly 

 larger head and other structural characters. Sexual marks are 

 not discernable in the four specimens before me.

Moderately stout and feebly ventricose, polished, impunctate, 

 piceous-black with slightly paler elytra ; legs and antennae testa- 

 ceous, the latter with the club blackish ; pubescence moderately 

 abundant, short, fine and not directed backward on the head, 

 somewhat bristling with long and finer and short and thicker 

 hairs on the prothorax throughout, rather short, sparse and re- 

 curved and without erect setse on the elytra, pale in color. Head 

 rounded, not quite as long as wide, the eyes moderate, anterior 

 and scarcely prominent ; antennal tubercles subobsolete; clj^peus 

 truncate or very feebly sinuate at apex. Antennae slender, a little 

 longer than the head and prothorax, the club abrupt and parallel ; 

 second joint as long and wide as the first, very feebly obconic, 

 nearly twice as long as wide, noticeably longer than the next two 

 and much thicker ; three to seven equal in width, similarly 

 smooth, feebly obconic; third just visibl^^ fourth ^, fifth -|, sixth 

 ^ and seventh ^, longer than wide ; eighth very slightly wider, 

 quadrate, just visibly darker in color; ninth nearly -f wider, a 

 little longer than w:ide ; tenth scarcely visibly wider than the 

 eighth and obviously wider than long ; eleventh not thicker, but 

 little shorter than the two preceding, gradually and obliquely 

 pointed. Prothorax subquadrate, not quite as long as wide, \ 

 wider than the head, parallel and broadly rounded at the sides, 

 narrowed slightly toward base, the surface with two feeble sub- 

 median fovese near the base, connected by a feeble transverse im- 

 pression, and with two small and sublateral fovese adjoining the 

 sablateral carina externally, one at the basal margin, the other|in 

 advance. Elytra f longer than wide, much more than twice as
