 third wider than prothorax at base, 2.6 times as long as prothorax, 

 length to width as 10:7; intervals flat, more convex toward base,

 deep. Scutellum 0.06 by 0.06 mm., with slight median furrow. 

 Claws with acute basal tooth.

Description: Length; 1.50 to 1.83 mm. 



Robust. Black; base of antennae and fore femora and tibiae 

 reddish brown ; middle and hind femora and tibiae piceous ; pubescence 

 on dorsal surface of prothorax and elytra fine, yellowish, very sparse; 

 white, coarser and denser laterally. Beak of male much shorter than 

 head and prothorax combined, slightly longer than prothorax, slightly 

 curved; in side view attenuate to apex, ventral margin nearly straight; 

 in dorsal view slightly expanded at basal fourth, apical two-thirds 

 nearly parallel-sided; moderately shining, with line punctures arranged 

 in rows, becoming sulciform laterally; basal three-fourths sparsely 

 pubescent. Beak of female as long as head and prothorax combined, 

 one-half longer than prothorax, moderately, evenly curved; in side 

 view attenuating to apex; in dorsal view nearly parallel-sided to apex, 

 antemial insertion minutely prominent; with sparse, fine punctures 

 throughout, moderately shining. Antennae inserted at basal fourth of 

 beak at distance from eye slightly greater than width of frons; first 

 segment equals next three, second slightly shorter than next two ; club 

 0.21 bj^ 0.07 mm. Eyes prominent ; frons narrow, not as wide as dorsal 

 tip of beak, with one lateral row of moderately coarse punctures and a 

 moderately wide, flat median interval. Prothorax at base one-third 

 wider than long, middle slightly narrower than base, apex two-thirds to 

 thi'ee-sevenths as wide as base; sides beyond basal lateral expansion 

 slightly converging to middle, rounding to constricted apex; in profile 

 dorsal surface slightl}^ arcuate, apical margin slightly raised; puncta- 

 tion 0.03 mm. in diameter, moderately deep, interspaces narrower 

 than diameter of punctures; basal fovea short, moderately deep, 

 narrow. Elytra at humeri one-third to two-fifths wider than pro-
