of punctures more distinct basally, interspaces irregular, from one to 

 three times as wide as punctures; basal fovea absent. Elytra at 

 hum.eri one-third wider than prothorax at base, 2.6 times as long as 

 pro thorax, length to width as 6:5; intervals flat, twice as wide as 

 striae, with one row of distant, minute punctures bearing minute 

 scales; striae moderately fine, deep, with one row of scales larger than 

 those on intervals. Scutellum triangular, 0.08 by 0.08 mm., with 

 no median depression. Front femora four times as long as wide. 

 Claws with acute basal tooth. 



Special male characters: Tibiae 2 and 3 armed with short, trian- 

 gular-acute mucrones. 



Material examined: One male determined by Sharp,

Description: Length, 1.67 to 1.91 mm.; width, 0.78 to 0.94 mm. 



Moderately robust. Black, elytra and prothorax somewhat aeneous, 

 femora and tibiae piceous; pubescence very fine, white, inconspicuous 

 on dorsal surface, somewhat coarser and denser on mesothorax. Beak 

 of male slightly shorter than head and prothorax combined, four- 

 sevenths longer than prothorax, moderately, evenly curved; apical 

 third nearly cylindrical, in dorsal view attenuate from antennal 

 insertion to apical thhd; basal two-thirds moderately dull, alutaceous, 

 sparsely punctured and pubescent, apical third shining, minutely 

 punctured. Beak of female longer than head and prothorax combined, 

 nearly twice as long as prothorax, moderately, evenly curved; apical 

 half nearly cylindrical, somewhat depressed at tip; in dorsal view 

 attenuate from antennal insertion to middle; basal three-fourths 

 rather strongly punctured, a distinct row of punctures above antennal 

 insertion extends to middle; pubescence sparse at base. Antennae 

 inserted at distance from eye equal to width of frons, of male at basal 

 fourth, of female at basal sixth of beak; first segment equals next 

 two, second segment shorter than next two; club 0.20 by 0.07 mm. 

 Eyes acutely prominent; frons wider than dorsal tip of beak, with a 

 slight, broad median depression and one lateral row of fine punctures. 

 Prothorax at base one-fourth longer than wide, middle about as wide 

 as base, apex three-fourths as wide as base; sides beyond obsolete 

 basal lateral expansion subparallel in basal half, rounded to constricted 

 apex; in profile dorsal surface is nearly flat; punctation very shallow, 

 about 0.03 mm. in diameter, interspaces equal to or wider than 

 punctures; basal fovea shallow, short. Elytra at humeri one-half
