Grenada — St. George's (Leeward side); and Canonan 

 Isle, Grenadine. Described from eight $ specimens. 



This species is evidently allied to U. vicin'us, Cress., 

 described from Cuba, but differs decidedly in having the 

 face and labrum black, the different coloured pubescence, 

 and by the dorsal abdominal fasciae being all widely 

 interrupted at the middle. 



Genus Melissa, Smith.

 velvety black pubescence, the face and tliorax above, in certain

 times the liind trochanters are narrowly margined with yellow at 

 apex ; tarsal joints 2-4 in certain lights, show a piceous or rufo- 

 piceous tinge ; the middle tibial spur is :|:"ufous, long and forked, the 

 anterior fork being serrated ; the first joint of the middle tarsi has 

 its apical hind angle produced into a spine ; while the hind tibial 

 spurs are finely serrate within. Wings hyaline, the anterior pair

 a triangular tuft of golden pubescence on the inner orbits 

 just above the antenme, while the hind femora are pro- 

 duced into a triangular lobe at base beneath. Three
