AET. 8 REVISION OF THE FLY GENUS BELVOSIA ALDRICH 9 



color, which extends to the oral margin; frontal bristles in a single 

 row, the lowest two or three extending almost transversely toward 

 the eye. Antennae black, second joint more than one-half the third; 

 arista missing. Palpi black. The parafacial hairs below the frontals 

 are black and rather strongly developed; the hairs of the cheek are 

 also black. The hair on the back of the head and the beard are 

 rather dark brown in color, a very unusual mark. 



Mesonotum damaged with glue so the pollen is spoiled. Sterno- 

 pleural four on one side and three on the other. Calypters brown. 



Abdomen uniformly black on the first and second segments; the 

 third and fourth uniformly and densely covered with pollen of a 

 peculiar deep reddish orange or burnt orange color, which extends to 

 the tips of the segments including the rows of bristles. The color of 

 this pollen is very characteristic and quite unlike the common forms. 



Legs black. 



Wings brown with a distinct yellowish tinge along the front part 

 near the base and becoming subhyaline around the anal angle. Bend 

 of fourth vein slightly oblique, its distance from the margin only a 

 little less than from the cross vein. Third vein with two bristles at 

 base. 



Length, 13 mm. 



Redescribed from the type specimen, now in the University of 

 Kansas collection; it is from San Domingo, West Indies. 



BELVOSIA FERRUGmOSA Townsend 



Belvosia ferruginosa Townsend, Trans. Amer. Ent. Soc, vol. 22, 1895, p. 71. 

 The original description is as follows: 



Length nearly 12 mm. Eyes green in life; front brownish red on each side, 

 more or less silvery poUinose; frontal vitta soft brownish golden; facial depres- 

 sion, sides of face and cheeks, rich silvery white pollinose, cheeks hairv. Antennae 

 dark brown, the third joint linear and nearly three times as long as second; 

 arista brown; palpi brownish black, yellowish on tips; vertex somewhat yellow- 

 ish; posterior orbits silvery white. Thorax and scutellum brownish red, the 

 former thinly pollinos before, leaving tlie beginnings of four narrow vittae; poste- 

 rior corners of mesoscutum yellowish, also a little yellowish behind humeri. Abdo- 

 men of a beautiful iron-rust yellow, in the first and second segments the yellow 

 shade predominating, in the third and fourth the iron-rust Jshade; first segment 

 brownish under scutellum; a median pair of macrochaetae on first and second, 

 a marginal row on third and fourth segments. Legs soft blackish, pulvilli and 

 claws yellow. Wings uniformly pale fuscous; tegulae same color. 



Bath, Jamaica (E. M. Swainson); bred from a lepidopterous chrysalis; one 

 male. A beautiful species. Type in coll. Townsend. 



The type of this species appears to be lost, as it is not in the Uni- 

 versity of Kansas collection where the other early types of Town- 

 send's are deposited. I have not found any specimens which I could 

 identify as belonging to this species.
