SUBGENUS TRICHAPION — KISSINGER 285 



expanded at antennal insertion, attenuate to apical two-fifths, nearly 

 parallel to tip; basal two-fifths sparsely pubescent, moderately punc- 

 tured, a line of punctures appears as a slight sulcus above antennal 

 insertion and extends to apical two-fifths; tip smoother, bare. An- 

 tennae inserted at basal fifth of beak, at distance from eye one-third 

 greater than width of frons; first segment equals next two, second 

 segment shorter than next two; club 0.18 by 0.06 mm. Eyes promi- 

 nent; frons mder than dorsal tip of beak, with a shallow median sulcus 

 and two lateral rows of punctures. Prothorax at base one-fourth 

 mder 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 surface nearlj^ 

 flat; punctation moderately deep, 0.03 mm. in diameter, interspaces 

 generally narrower than punctm'es; basal fovea shallow, punctiform. 

 Elytra at humeri one-third wider than prothorax at base, nearly three 

 times as long as prothorax, length to width as 10:7; intervals twice 

 as wide as striae, slightly convex, with two rows of punctures bearing 

 scales. Scutellum elongate-triangular, 0.07 by 0.04 mm. Front 

 femora 3.3 times as long as wide. Claws with acute basal tooth. 



Special male characters: Tibiae 2 and 3 armed with moderately 

 long, subangulate mucrones. 



Holotype: Male (USNM 63419) from Frontera, Tabasco, Mexico, 

 in Thomas Lincoln Casey Collection.

Figure 3,/-?: 



Description: Length, 1.75 to 1.94 mm.; width, 0.87 to 1.05 mm. 



Moderately robust. Black, elytra slightly aeneous. Pubescence 

 white, fine, scant on dorsal surface, denser on mesothorax. Male beak 

 equal in length to head and prothorax combined, two-fifths longer than 

 prothorax; slightly curved, more noticeably deflexed at apical fourth; 

 apical third is nearly cylindrical; in dorsal view moderately expanded 

 laterally at antennal insertion, attenuate to apical third; somewhat 

 alutaceous, punctures arranged in rows, a moderately strong series of 

 punctures above antennal insertion, tip somewhat more shining; basal 

 two-thirds sparsely pubescent. Female beak longer than head and 

 prothorax combined, four-fifths longer than prothorax; more strongly 

 deflexed at apical third; in lateral view subparallel throughout, in 

 dorsal view moderately strongly expanded laterally at antennal inser- 

 tion, attenuate to middle, tip strongly expanded; dull, alutaceous, 

 shallow punctures arranged in rows similar to male, tip smoother, 

 slightly more shining, glabrous distad of antennal insertion. An- 

 tennae inserted at basal fourth of beak at distance from eye one-half
