DESCRIPTIO^'": Length, 1.44 to 1.75 mm.; width, 0.68 to 0.87 mm. 



Moderately robust. Black, elytra somewhat aeneous; pubescence 

 on dorsal surface yellowish, fine, sparse, somewhat coarser and white 

 at base of interval 3, laterally and ventrall}^ white, slightly coarser 

 there, not noticeably denser than on dorsal surface. Male beak 

 slightly shorter than head and pro thorax combined, one half longer 

 than prothorax, moderately, evenly curved; in lateral view apical 

 half nearly parallel-sided; dorsal view with moderate lateral expansion 

 over antennal msertion, attenuate to beyond middle, slightly com- 

 pressed, then expanding slightly, apical fourth parallel-sided; basal 

 half dull, alutaceous, sparsely pubescent, sparsely punctured, with 

 slight furrow above antennal insertion, apical half shining, glabrous, 

 very sparsely punctured. Female beak nearly one-half longer than 

 head and prothorax combined, twice as long as prothorax; moderatel}^ 

 evenly curved; nearly cylindrical throughout, slightly expanded 

 laterally at antennal insertion, dull, alutaceous, with a row of 

 punctures above antennal insertion, with fine, sparse scales in front 

 of antennal insertion. Antennae inserted at basal fifth of beak at 

 distance from eye slightly less than width of frons of male, of female 

 inserted at basal sixth of beak at distance from eje equal to width 

 of frons; fij'st segment of male equals next two, of female equals next 

 three; second segment of male shorter than next two, of female equal 

 to next two; club 0.15 by 0.06 mm. Eyes moderately prominent; 

 frons wider than dorsal tip of beak, with slight median furrow and 

 two irregular lateral rows of fine punctures. Prothorax at base one- 

 fourth wider than long, middle narrower than base, apex five-sevenths 

 as wide as base; sides beyond basal lateral expansion nearly parallel 

 to middle, rounding to constricted apex; in profile dorsal surface nearly 

 flat; punctation 0.02 to 0.03 mm. in diameter, moderately deep, 

 interspaces generally narrower than diameter of punctures, alutaceous; 

 basal fovea moderately deep, short. Elytra at humeri one-third wider 

 than prothorax at base, 2.75 times as long as prothorax, length to 

 width as 15 : 11; intervals nearly flat, somewhat convex toward base, 

 in part with two rows of fine punctures bearing scales, smooth, trans- 

 verse rugae fine, sparse, not conspicuous; striae fine, moderately deep.
