of the second segment below greyish pollinose and witli a i'ew 

 short yellow hairs, a little yellow pile on the anterior angles 

 of the' first segment also ; central portion of the third segment 

 somewhat bluish, the band of black pile on the posterior 

 margin very conspicuous and sharply defined when the insect 

 is viewed obliquely from the front ; this band does not reach 

 the posterior angles of the segment below, while the ends are 

 divided by a tapering band of greyish pollen, on which the 

 pile is somewhat sparser, while in front of it there is a line of 

 hair projecting at a different angle from the rest, so that on 

 looking at the ventral surface we appear to see the margin of 

 an additional segment ; ground-colour of the fifth segment, 

 when viewed from behind, tawny, with a dull greyish pollinose 

 transverse band, divided in the median line and occupying 

 rather more than the anterior half of the segment ; this is 

 most conspicuous when the specimen is held so that the eye 

 looks directly at the edge of the hind margin of the fourth 

 segment; in certain positions a narrower greyish pollinose 

 band is also visible on the sides of the third and fourth seg- 

 ments, lying nearer to the anterior than to the posterior 

 margin, but not in contact with either, and dying away on the 

 dorsal surface before reaching the median line ; a narrow dull 

 median longitudinal stripe is faintly indicated when the 

 abdomen is viewed obliquely from behind ; the pile clothing 

 the fifth segment thicker and longer than elsewhere. Legs 

 clothed with black pile, the posterior surface of the last pair 

 of femora thinly clothed nearly to the tip with short silky 

 yellowish pile ; all the coxa3, the bases of the anterior femora 

 above, and those of the middle pair posteriorly also with some 

 yellow pile ; femora and tibiae reddish brown, the latter darker 

 than the former ; tarsi black, short and broad ; claws black. 

 Wings brown, somewhat lighter towards the posterior margin, 

 narrow and tapering to the tips, somewhat lancet-shaped j 

 alulce dark brown, of moderate size, subquadrate ; squamce 

 dark brown, fringed with short brown pile, and showing no 

 light margin. 



Para, Brazil {Bates) ; one specimen. 



This species presents no resemblance to any of those pre- 

 viously described : it is at once distinguished from Cutiterebra 

 analis, Macq. [api'calis, Guer.), by the thorax and scutellum 

 (with the exception of the anterior margin of the former) 

 being entirely clothed with black pile instead of with golden 

 yellow ; while the unstriped thorax and the shining metallic 

 abdomen, with its black transverse band, render it impossible 

 to confuse C. nigricincta with G. rufventris, Macq.
