pepsinae: tribe macromerini 167 



forest floor"; and a male reared May 9, 1911, from a mud cell found 

 under a stone on golf links at Lawrence, Kans., by F. X. Williams. 

 My own collecting experience indicates the typical habitat to be on 

 or near the ground in rather open woods or along the edges of woods, 

 usually in sunny spots. 



This species appears to occur in most of the United States, southern 

 Canada, and northern Mexico. Definite records from many of the 

 southeastern states, and from the Northwest, except for a single 

 capture in Oregon, are lacking. Adults occur on or near the ground 

 in open woods or along the edges of woods. They are on the wing 

 from late spring to early fall. 



Genus Ageniella Banks 



Clypeus of moderate size, the apical margin truncate, somewhat 

 concave, or convex, often with a median blunt point; mentum of 

 female with a few long, slender, weakly curved hairs; front tibia with- 

 out one of the apical bristles specialized; dorsal edge of hind tibia 

 smooth in the male, smooth or serrate in the female; last tarsal seg- 

 ment with or without preapical bristles beneath; propodeum without, 

 or sometimes with a few long erect hairs; first tergite without a line 

 separating off the epipleuron; female without a pygidial area; sub- 

 genital plate of male rather narrow. 



This genus is best developed in the Neotropics, with a considerable 

 body of species occurring in the southern portion of the Nearctic 

 Region. It seems not to occur in the Old World, unless the oriental 

 Meragenia should be included as a subgenus. Ageniella leucippe Banks 

 1941, described from the Solomon Islands, is a species of Auplojms 

 (new combination). The species have considerable structural diver- 

 sity and may be separated into natural groups, the more distinct of 

 which are treated here as subgenera. 



Keys to the subgenera of Ageniella 



MALES 



1. Propodeum with long erect sparse hairs, in addition to the short pubescence; 



third cubital cell receiving the second recurrent vein near its basal 0.35. 



Ameragenia (p. 215) 



Propodeum without long erect hairs or with only a very few such hairs; third 



cubital cell receiving the second recurrent vein near or beyond its middle. . 2 



2. Sixth sternite with a median apical rounded eminence; face and clypeus black, 



the face on each side with a narrow longitudinal white or yellowish mark 

 (this mark sometimes obsolescent) ; spurs of fore and middle tibiae usually 

 stramineus or dusky stramineus (exception: A. reynoldsi); spurs of hind 



tibia fuscous; forewing 4.5 to 8.5 mm. long Leucophrns (p. 168) 



Sixth sternite without a median apical rounded eminence; face and clypeus 

 usually black and without pale markings; tibial spurs variously colored; 

 forewing 3.3 to 10.0 mm. long 3
