SUBGENUS TRICHAPION — KISSINGER 317 



thorax, slightly curved; in lateral view apical third nearly parallel, 

 in dorsal view slightly expanded laterally at antennal insertion, 

 attenuate to slightly past middle, beak not compressed or expanded 

 toward tip; basal two-thirds punctured and densely covered with 

 squamose pubescence, apical third shining, glabrous, nearly impunc- 

 tate. Antennae inserted at basal fifth of beak, at distance from eye 

 equal to width of frons; first segment equal in length to next two, 

 second segment shorter than next two, club 0.15 by 0.07 mm. Eyes 

 prominent; frons wider than dorsal tip of beak, with slight median 

 furrow, and two irregular, lateral rows of fine punctures. Prothorax 

 at base one-third wider than long, middle narrower than base, apex 

 three-fourths as wide as base; sides beyond basal lateral expansion 

 nearly parallel to middle, rounded to constricted apex; in profile 

 dorsal siu-face slightly arcuate; punctation 0.03 mm. in diameter, 

 moderately deep, interspaces somewhat narrower than diameter of 

 punctures; basal fovea shallow, punctiform. Elytra at humeri 

 one-third wider than base of prothorax, 2.5 times as long as pro- 

 thorax, length to width as 15:12.5; intervals twice as wide as striae, 

 somewhat convex, with one row of fine punctures bearing fine scales; 

 striae deep, fine. Scutellum elongate-triangular, 0.08 by 0.06 mm., 

 with obscure median furrow. Front femora 3.75 times as long as 

 wide. Claws with acute basal tooth. 



Special male characters: Tibia 2 armed with moderately long, 

 slender mucro.

Figure 9,a-c 



Description: Described from a unique specimen. 



Length, 1.50 mm.; width, 0.75 mm. 



Moderately robust. Specimen teneral, antennae and apices of 

 tibiae and tarsi paler; pubescence white, fine, inconspicuous on dorsal 

 surface of elytra, somewhat longer and very sparse on dorsal surface 

 of prothorax, somewhat denser on sides of mesothorax and metepister- 

 num. Beak slightly shorter than head and prothorax combined, 

 three-fifths longer than prothorax, moderately, evenly curved; apical 

 half nearly cylindrical, in dorsal view not attenuate beyond slight 

 lateral expansion over antennal insertion; basal two-thirds dull, very 

 sparsely pubescent, finely, shallowly punctured in rows, apical third 

 more shining. Antennae inserted at basal fifth of beak, at distance 

 from eye about equal to width of frons; first segment equal to next
