thorax at base, from 2.25 to 2.50 times as long as prothorax, length 

 to width as 10 : 9; intervals nearly flat, twice as wide as striae, with 

 one occasionally irregular row of fine punctures with fine scales, 

 interval 2 with two rows of punctures, smooth, without transverse 

 rugae; striae moderately deep, coarse. Scutellum rounded, 0.06 by 

 0.06 mm., with broad, shallow median sulcus. Front femora 3.8

Description: Length, 1.42 to 1.50 mm. 



Moderately robust. Black; base of antennae piceous or yellow; 

 pubescence on dorsal surface of prothorax and elytra fine, white, 

 very sparse, denser and coarser on sides of mesothorax and meta- 

 thorax; male with ventral surface covered with scales much coarser 

 than those of female. Beak of male moderately stout, strongly 

 attenuate, much shorter than head and prothorax combined, one- 

 third longer than prothorax, moderately curved; moderately expanded 

 at antennal insertion, attenuate iu middle third, parallel-sided in 

 apical third, apical third slightly compressed, tip slightly expanded; 

 sparse pubescence in basal two-thirds, punctures slight, sparse, 

 mainly in basal two-thirds, apical region smoother; moderately 

 shining beyond antennal insertion. Beak of female slightly longer 

 than head and prothorax combined, three-fourths longer than pro- 

 thorax, moderately curved, more strongly deflexed in apical third; 

 in lateral view attenuate beyond antennal insertion to apical third 

 which is nearly parallel-sided; in dorsal view stout at base, slightly 

 expanded over antennal insertion, slightly attenuate to tip; dull, 

 alutaceous throughout, with shallow, very fine punctures; with a few 

 scales behind antennal insertion. Antennae of male inserted at 

 basal fourth of beak at distance from eye slightly greater than -width 

 of frons, of female inserted at basal fifth of beak at distance from 

 eye equal to width of frons; first segment of male equals next two, 

 of female somewhat longer than next two ; second segment somewhat
