SUBGENUS TRICHAPION — KISSINGER 315 



sparse, white and slightly coarser on sides and apex of elytra, on sides 

 of prothorax, mesothorax, and metathorax still coarser and somewhat 

 more conspicuous. Beak shorter than head and prothorax combined, 

 one-third longer than prothorax, moderately, evenly curved; in 

 lateral view attenuate from antennal insertion, apicalUhh-d nearly 

 parallel-sided, in dorsal view attenuate from antennal|insertion to 

 apical third, there slightly compressed then expanded, apical third 

 nearly parallel; basal three-fourths pubescent, basal two-thirds dull, 

 alutaceous, punctured, apical third shining, sparsely punctured. 

 Antennae inserted at basal fifth of beak at distance from eye about 

 equal to width of frons; first segment and second segment each equal 

 to next two segments combined, club 0.20 by 0.07 mm. Eyes promi- 

 nent; frons slightly wider than dorsal tip of beak. 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 nearly flat; punctation 0.03 mm. in diameter, moderately 

 deep, interspaces narrov/er than diameter of punctures; basal fovea 

 shallow, punctiform. Elytra at humeri one-third wider than pro- 

 thorax at base, 2.65 times as long as prothorax, length to width as 

 4:3; intervals nearly flat, twice as wide as striae, generally with two 

 rows of fine scales; striae deep, fine. Scutellum elongate-triangular, 

 0.08 by 0.05 mm. Front femora 3.3 times as long as wide. Claws 

 with acute basal tooth. 



Special male characters: Tibia 2 armed with long, thin, curved 

 mucro; first segment of fore tarsi with outer apical angle produced 

 into a short spine. 



Female is not known. 



Types: Holotype male (USNM 63422), Huauchinango, Puebla, 

 Mexico, June 1954, D. G. Kissinger. Four male paratypes: 3 

 (BMNH, CAS, DGK) with same data as holotype and 1 (DGK) 

 from El Salto, San Luis Potosf, Mexico, Jan. 22, 1953, D. G. Kissinger. 



Remarks: Specimens from Huauchinango, Puebla, were taken 

 while beating in a scrub oak and pine forest at about 5,000 feet 

 elevation,

Description: Length, 1.56 mm.; width, 0.77 mm. 



Moderately robast. Black; base of antennae yellow; pubescence 

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

 sparse, on head, basal two-thirds of beak, sides of prothorax, meso- 

 thorax, and metathorax very coarse, more conspicuous. Beak 

 shorter than head and prothorax combined, one-sixth longer than pro-
