Moderately robust. Black; tibiae, tarsi, and antennae dark 

 reddish yellow; pubescence conspicuous, elytral suture in basal third 

 behind scuteUum clothed with broad, dense, pearly scales, these finer 

 at base of intervals; cii'cular area from humeri to apical third clothed 

 with fine, yellow scales, giving area darker appearance, remainder of 

 elytra clothed with moderately coarse, sparse, white scales; head and 

 base of beak with sparse, coarse, pearly scales. Male beak one-fourth 

 longer than pro thorax, nearly straight; in dorsal view moderately 

 expanded at antennal insertion, attenuate strongly to middle, thence 

 cylindrical to tip, in lateral view expanded ventrally at antennal 

 insertion, attenuate to middle; dull, punctured and scaly in basal half, 

 apical half bare, polished, and subimpunctate. Female beak as long 

 as head and pro thorax combined, one-half longer than pro thorax, 

 slightly curved; apical two-thirds cylindrical, in dorsal view strongly 

 dilated at antennal insertion, in lateral view basal sixth stout, slightly 

 humped dorsally at antennal insertion; basal sixth dull, punctured, 

 and scaly, remainder bare, polished and subimpunctate. Antennae 

 inserted at distance from eye slightly less than Avidth of frons, of male 

 at basal fifth, of female at basal sixth; first segment equals next two; 

 second segment nearly equals next two; club 0.21 by 0.08 mm. Eyes 

 large, prominent; frons wide, with two irregular rows of punctures 

 separated b}^ a wide area with an indistinct median sulcus, base of 

 frons with moderate punctures. Prothorax at base one-third wider 

 than long, middle narrower than base, apex two-thirds as wide as 

 base; sides beyond basal lateral expansion slightly converging to 

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

 slightly arcuate; punctation 0.03 mm. in diam.eter, deep, interspaces 

 generally one-half as wide as punctures; basal fovea short, shallow, 

 wide. Elytra at humeri one-third wider than prothorax at base; 2.5 

 times as long as prothorax, length to width as 5:4; intervals convex, 

 twice as wide as striae, with two or three u-regular rows of fine punctures 

 bearing scales; striae deep, with a row of scales similar to those on 

 adjacent portion of interval. Scutellum triangular, 0.06 by 0.06 

 mm., with slight median sulcus in basal half. Front femora 3.3 

 times as long as wide. Claws with broad basal tooth. 



Special male characters: Tibiae 2 and 3 armed with small, curved 

 mucrones which are slightly angulate ventral!}^ at middle; tibia 1 

 with inner anterior surface with a flattened, striate area; tarsus 1 

 with outer apical angle of first segment produced into a short, blunt 

 spine.
