 one-half their own diameter from the eye margin; antennal scrobes 

 shallow; front, vertex, and eyes with a sparse, fine pubescence. 

 Antennae and wings very nearly as in A. alhopleuralis Ashmead, but 

 the club is proportionately a little wider, and the basal hairless 

 streak on posterior margin of wing extends but a short distance be- 

 yond the end of the oblique hairless streak. Length: 1.0 to 1.2 mm. 



Front and vertex orange yellow, the mesonotum clay yeUow; 

 face, cheeks, and occiput colored nearlj^ like the front and vertex l)ut 

 more pinkish (apparently discolored by immersion in alcohol, in
