Lateral ocellus separated from the eye by about 3.5 its diameter; clypeus with 

 a subapical row of about 4 to 8 long suberect hairs, above which are many 

 shorter suberect hairs which are more than half as long as the subapical row; 

 long suberect hairs of head and thorax abundant; dorsal longitudinal carina 



on hind tibia subserrate 1. toussainti (Banks) 



3. Base of forewing infuscate for a distance equal to 0.5 or more the length of the 

 anal lobe; base of hind wing infuscate for a distance equal to 0.6 or more the 

 length of the anal lobe; forewing averaging about 23 mm. long. 



2a. ustulata ustulata Dahlbom 



Base of forewing infuscate for a distance equal to 0.4 or less the length of the 



anal lobe; base of hind wing infuscate for a distance equal to 0.3 or less the 



length of the anal lobe, the anal lobe itself mostly or entirely infuscate (pi. 



1, fig. 3); forewing averaging about 21 mm. long.

1. Hemipepsis toussainti (Banks) 



Mygnimia toussainti Banks, 1928, Studies on Cuban insects (Harvard Univ. 

 Press), vol. 1, p. 5, c?. Type: d", Port au Prince, Haiti (Cambridge). 



Forewing 17 to 20 mm. long in the male, 23 to 27 mm, long in the 

 female; long suberect hair on basal part of male clypeus about 0.6 

 as long as the apical width of the clypeus; nerveUus beyond the 

 cubiteUa by 0.2 to 0.35 the average width of the submediellan cell; 

 median ventral row of bristles on last segment of female tarsi restricted 

 to its basal 0.5 to 0.65. Otherwise structurally similar to H. ustulata. 



Colored as in H. ustulata ustulata except that in the male the basal 

 and apical infuscation of the wings is a little broader and that in the 

 female the flagellum is orange, with the basal 0.4 ± of its first segment 

 infuscate, the mesoscutum has only a very small amount of greenish 

 blue iridescence visible at some angles, and the apical part of the 

 forewing is a little less abruptly infuscate. The male flagellum is 

 sometimes tinged with orange beneath.
