fectly and has the three purple stripes on the dorsum of the thorax 

 well defined. Length, 16.5 mm.; length of proboscis including 

 basal shield, 23 mm. 



The smaller specimen (Plate II, fig. 10) is more blue green and 

 less purple. The infuscation of the wings is paler and there is 

 none of the black pile on the thorax at the base of the wings, and 

 on the pleura. The femora are blackish purple instead of black

 Antennae blackish brown, second joint with a few short hairs, 

 third joint pointed and yellowish at the extreme base. Squamae 

 purplish brown with black rims. Genitalia clothed with yellow- 

 ish pile, longer than on the rest of the abdomen, and about the 

 same color and length as that on the venter. The venter is en- 

 tirely metallic purple. Length, 14.5 mm.; length of proboscis, 

 16 mm.

 with black pile. Pleura and humeri with long fine black pile. 

 Venter shining brown with purple and coppery green reflections,
