Campinas, Brazil (Hempel). The yellow marks at sides of face 

 are not on clypeus. Hair of thorax above gray. Male with short, 

 thick scape. Female with bright orange spot at end of mandibles; 

 the spots on sides of face may be almost obsolete.

 a variable orange band on apical part, abdomen beyond middle of 

 second segment ferruginous; eyes dark greenish, diverging below;

 apex of liugellum reddened; third antennal joint about as long as 

 the next two together; hair of head dark chocolate; hair of thorax

Guanajuato, Mexico, two collected by Dr. A. Duges. They bear 

 the numbers 763 and 524. Closely related to X. gabhi (Cresson), 

 from Costa Rica, but distinguished by the very dark wings and dark 

 basal half of second abdominal segment. X. fuliginosa Gribodo, 

 from Venezuela, has the abdomen colored as in X. dugesi, but the 

 wings are quite differently colored. The legs of one specimen of 

 X. dugesi carry large pollen grains, apparently of some Cucurbi- 

 taceous plant.
