increasing uniformly in width, almost similar in form; ninth 3^-^, tenth %y 

 wider than long; eleventh still stouter, oval, as long as the two preceding, 

 ogival and feebly oblique at apex. Prothorax conic, the sides very feebly arcu- 

 ate, about as long as wide ; apex scarcely more than }4 as wide as the base, the 

 latter % wider than the head ; surface perfectly even throughout. Elytra 3^ 

 longer than wide, barely twice as long as the prothorax and about % wider, 

 widest and with the sides rather more arcuate well before the middle; apex 

 somewhat acute ; humeral plica narrow and pronounced, moderate in length, 

 the subhumeral impression rather large and conspicuous; fovese distinct; sub- 

 Butural impressions almost obsolete, the suture not at all beaded toward base. 

 Under surface pale throughout. Legs moderate, the four anterior femora 

 moderately, the posterior rather feebly, clavate. Length 1.0 mm.; width 

 0.45 mm.

The type and only specimen known to me is a female. The 

 species may be known among its immediate neighbors by the 

 strongly clavate antennEe, wholly unimpressed pronotum and 

 other characters. 



31. C pallidum n. sp. — Narrowly suboval, polished and impunctate, 

 rufo-testaceous throughout, the antennse concolorous, the legs still paler and 

 more brownish ; pubescence only moderately abundant, coarse, pale in color, 

 rather short and recurved on the elytra. Head moderate, slightly transverse, 

 subcircular behind the rather inconspicuous eyes; clypeus not visibly ridged 

 along the middle, the tooth very minute, acutely triangular. Antennae slender, 

 rather longer than the head and prothorax, the club strong but not abrupt, its 

 joints increasing in width; second joint subcylindric, distinctly shorter and 

 narrower than the first, % longer than wide and subequal in length to the 

 next two; three to six distinctly narrower, subequal among themselves and 

 not quite as long as wide; seventh about }{ wider than the sixth, nearly 3^ 

 wider than long; eighth nearly }4 vdder than the seventh, % wider than long, 

 rounded at apex from the middle; ninth and tenth subsimilar, about 3^ wider 

 than the eighth, % aD<i % wider than long respectively; eleventh short, not 

 longer than wide, much shorter and somewhat stouter than the two preceding, 

 obtusely, rapidly ogival and scarcely at all oblique at apex; joints eight to 

 eleven almost uniformly increasing in width. Prothorax conic, the sides 

 almost straight, not longer than wide; apex ^ as wide as the base, the latter 

 % wider than the head; surface perfectly even throughout. Elytra nearly %. 

 longer than wide, barely twice as long as the prothorax and nearly % wider, 

 rather acutely rounded behind, widest near basal third, the sides almost evenly 

 arcuate; humeral plica small, narrow and inconspicuous, the subhumeral im- 

 pression small and feeble; fovese small; subsutural impressions very feeble, 

 the suture not or scarcely elevated near the base. Legs moderate, the anterior 

 femora clavate, the posterior four quite feebly so. Length 0.9 mm.; width 

 0.35 mm.
