SUBGENUS TRICHAPION — KISSINGER 357 



fourth smooth, shining. Antennae inserted at distance from eye 

 one-half greater than width of frons, of male at basal third, of female 

 at basal fourth of beak; first and second segments each equal to next 

 two, club 0.17 by 0.07 mm. Eyes moderately prominent; frons wider 

 than dorsal tip of beak. Prothorax at base slightly wider than long, 

 middle about equal to base, apex three-fourths as wide as base; sides 

 beyond slight basal lateral expansion slightly expanding to middle 

 then rounded to constricted apex; in profile dorsal surface nearly 

 flat; punctures deep, 0.03 mm. in diameter, interspaces about one-half 

 diameter of punctures, slightly alutaceous; basal fovea deep, puncti- 

 form. Elytra at humeri one-third wider than prothorax at base, 2.6 

 times as long as prothorax, length to \vidth as 13 : 8.5; intervals 

 about twice as Avide as striae, rather convex, with one row of punc- 

 tures; striae fine, moderately deep. Scutellum triangular, 0.06 by 

 0.06 mm., with moderate median furrow. Front femora slightly 

 more than three times as long as wide. Claws with acute basal tooth. 



Special male characters: Tibiae 2 and 3 armed with long, simple 

 mucrones. 



Material examined: Five specimens including material in the 

 Fall Collection. 



Known distribution: 



United States: Iowa: Dickinson, Johnson, and Story Counties; Iowa City, 

 H. F. Wickham (USNM); Lake Okoboji, July 24, Aug. 26, 1916, L. L. Buchanan 

 (USNM). Mmowt(USNM). iVe6rasA;a (USNM). Kansas; Topeka (USNM). 



Remarks: No types of this species were found in either the J. L. 

 LeConte Collection or the U. S. National Museum, the two collections 

 containing most of Smith's types. It is necessary therefore to follow 

 Fall (1898) in his interpretation of this species. 



Fall (1898) did not list distribution records for this species, evidently 

 through an oversight. Leng (1920) gives the locality of this species 

 as Lower California, which is certainly an error.

Figure l5,d,o 



Description: Length, 1.75 to 1.80 mm.; width, 0.80 to 0.87 mm. 



Moderately robust. Black, prothorax and elytra aeneous; pubes- 

 cence inconpsicuous, white, very fine, slightly coarser and more 

 conspicuous on sides of prothorax, mesothorax, and metathorax. 

 Beak of male shorter than head and prothorax combined, one- third 

 longer than prothorax, moderately curved; in side view nearly parallel-
