MALE. — Length about 10mm. Head and thorax black; clypeus pale primrose-yellow, with two black spots; abdomen red and black; pubescence dull whitish, ochreous on front, occiput, and dorsum of thorax; build more slender than in prunorum.
This is in all respects closely similar to prunorum, but differs in being smaller, the antennae not ferruginous, the pubescence of the face relatively longer, the pubescence of the face, cheeks, pleura, and mesothorax greyish white instead of fulvous, the basal process of the labrum not emarginate, the tegulae dark brown, the mesothorax duller, the middle femora not so broad, the punctuation of the abdomen finer, the second abdominal segment black at base.
The flagellum is black, not fulvous beneath as in modesta. The scape shows only the slightest rufous stain in front, the mandibles are wholly black, bituberculate at base, the second segment of the abdomen is not entirely ferruginous as in fastuosa, which must however be closely similar.
HABITAT. — College Farm, Mesilla Valley, NM, April 9,1895, on plum (J. E. Casad, 164).
