SUBGENUS TRICHAPION KISSINGER 275 



tip; in the male it is pubescent to the tip and in the female is pubescent 

 to a point well in front of the antennal insertion. The A. griseum 

 group overlaps the range of the A. simile group particularly in Eastern 

 North America and extends into South America. It is interesting 

 to note that the superficial resemblance of A. sayi Gyllenhal (of the 

 A. griseum group) to A. simile is great enough that in at least two 

 cases in the material studied the two species were confused by com- 

 petent coleopterists.

Description: Length, 2.75 to 3.25 mm.; width, 1.33 to 1.50 mm. 



Moderately robust. Black; pubescence white, silvery, fine, long, 

 dense. Male beak equal to, to slightly longer than, head and pro- 

 thorax combined, three-fifths to four-fifths longer than prothorax, 

 slightly curved; subcylindrical throughout, slightly expanded laterally 

 at antennal insertion; rather densely, finely punctured, with minute 

 scales to near apex, tip slightly smoother. Female beak one-ninth to 

 two-fifths longer than head and prothorax combined, four-fifths to 

 2.25 times as long as prothorax, slightly curved, subcylindrical, 

 slightly expanded laterally at antennal insertion and at apex; punc- 

 tation and pubescence similar to male, tip polished, bare. Antennae 

 of male inserted at distance from eye 2.5 times width of frons, at 

 middle to slightly basad of middle; of female at distance from eye 

 three times width of frons, slightly basad of middle; first segment 

 equals next five, second segment slightly longer than third; club 0.27 

 by 0.10 mm. Eyes prominent; frons of male slightly narrower than 

 dorsal tip of beak, of fem.ale equal to dorsal tip of beak, with slightly 

 concave area medially. Prothorax at base about one-fifth wider than 

 long, middle slightly narrower than base, apex three-fourths as wide 

 as base; sides beyond acute basal lateral expansion subparallel to 

 middle, rounded to slightly constricted apex; in profile dorsal surface 

 nearly flat (slighth'^ convex in some females) ; punctation fine, moder- 

 ately deep, dense, uniform; basal fovea shallow, broad, short. Elytra 

 at humeri one-third v^ader than prothorax at base, about three times 

 as long as prothorax, length to width as 15:11 to 3:2; intervals 

 convex, about twice as wide as striae, with four to six rows of fine 

 scales; striae deep, coarse, scales in striae similar to those on interval.
