SUBGENUS TRICHAPION — KISSINGER 319 



striae moderately deep, fine. Scutellum elongate-triangular, 0.08 

 by 0.04 mm. Front femora 4.5 times as long as wide, claws with 

 acute basal tooth. 



Special male characters: Tibia 2 armed with fine mucro; first 

 segment of fore tarsus elongate, nearly four times as long as wide, 

 ventral surface clothed with long cilia. 



Female is not known. 



Types: Holotype, male (USNM 63424), 20 miles east of Morelia, 

 Michoacdn, Mexico, Mar. 7, 1953, D. G. Kissinger. Five male para- 

 types: 4 (BMNH, CAS, AMNH, DGK) with same data as holotype 

 and 1 (DGK) from near Huauchinango, Puebla, Mexico, June 1954, 

 D. G. Kissinger. 



Remarks: Material from 20 miles east of Morelia, Michoac^n, 

 was taken on oak leaves. The specimen from Huauchinango, Puebla, 

 was taken while beating in a scrubby oak and pine forest at about 

 5,000 feet elevation. 



A specimen taken with the type series from Morelia shows (fig. 9,i) 

 even stronger development of the male secondary sexual modification 

 of the fore tarsus. The first segment is slightly longer and about 

 twice as broad as that of the typical specimens and the second segment 

 is much longer and broader. This specimen is thought to be an indi- 

 vidual variant and is not included in the paratype series.

Description: Length, 2.00 mm.; width, 0.87 mm. 



Moderately robust. Black; pubescence white, on dorsal surface 

 fine, inconspicuous, under eyes, on sides of pro thorax, meso thorax 

 and metathorax coarser and more conspicuous. Beak of male shorter 

 than head and prothorax combined, one-seventh longer than pro- 

 thorax, slightly curved; in lateral view attenuate from antennal 

 insertion to apex; in dorsal view apical half nearly parallel-sided; 

 with sparse, fine punctures and scales in basal two-thirds. Antennae 

 inserted at basal fourth, at distance from eyes equal to width of 

 frons; first segment shorter than next two, second segment slightly 

 longer than third; club lacldng on specimen. Eyes prominent; frons 

 wider than dorsal tip of beak, with rather deep, narrow median 

 sulcus and one lateral row of subconfluent punctures. Prothorax 

 at base one-fourth wider than long, middle slightly wider than base, 

 apex three-fourths as wide as base; sides beyond acute basal lateral 

 expansion rather strongly diverging to middle, rather strongly rounded 

 from base to constricted apex ; in profile dorsal surface slightly arcuate ; 

 punctation 0.03 mm. in diameter, moderately deep, interspaces 

 narrower than punctures; basal fovea moderately deep, wider at
