356 CHARLES T. BRUES. 



Palpi and proboscis reddish yellow, a strong bristle at the lower corner of the 

 eye. Abdomen opaque, the first segment margined with yellow, second segment 

 elongated, its lateral angles with long black hairs; sixth segment not elongated, 

 but usually with a yellow border which is also sometimes visible on the other 

 segments. Hypopygium of moderate size, with long hairs and a distinctly pro- 

 truding, yellow-black, hairy, sheath-like appendage. Legs pieeous, the trochan- 

 ters and knees, front tibiae and their tarsi reddish yellow; femora thickened. 

 Fore tibia with a bristle at the basal third ; middle ones with a pair at the b:ise 

 and a second outer bristle at the apical third, as well as a long apical spur. Hind 

 tibise clavately thickened, but without a groove, with short recumbent filiation 

 on the posterior face ; with an external bristle at the basal third, and another 

 just before tbeapex, which bears two spurs. Wings strongly tinged with fuligi- 

 nous brown ; costal vein attaining the middle of the wing, rather stout, especially 

 at the base, and pieeous; the other veins yellowish brown. Cilialion of costal 

 vein long and sparse, third vein not forked, finely bristly on its basal third ; first 

 segment of costal vein not much longer than the second ; fourth vein sharply 

 arcuate at base and straight at apex. 



The female has a somewhat smaller third anteunal joint and the 

 arista is a little more strongly pubescent. 



This species was recorded from North America by Coquillett. 

 I have seen no specimens from this country. 



Hypocera grenadensis sp. nov. (Plate vi, fig. 24.) 

 Female. Head black, front shining, two anterior frontal bristles small, reclin- 

 ate, next row large, arranged in a straight line, as are also the two upper rows. 

 No ocellar tubercle present, but the front bears a deeply impressed median lon- 

 gitudinal line. Antenna; somewhat obtusely pointed, dull ferruginous, darker 

 where the subapical feathered black arista is inserted. Palpi small, bristly, red- 

 dish brown. Dorsum rather shining, black, except for slightly yellowish anterior 

 margin and humeral angles. One pair of dorsocentral macrochsetse and two 

 distinct marginal scutellar bristles, besides two very small lateral ones. Halteres 

 reddish yellow. Abdomen yellowish brown except for small subtriaugular spots 

 laterally on each segment; apical segment black. Ovipositor long, exserted, 

 but not more heavily chitinized than usual. Legs honey yellow; anterior tibiae 

 with a bristle on the outer side at basal and apical third; middle tibiae with a 

 pair of stout bristles on outer side at basal third and another smaller subapical 

 one, besides a very long spur at apex. Posterior tibise witli a single external 

 bristle at basal third, another subapical one and two apical spurs. Hind tarsi 

 very long, the first joint bristly below. Wings hyaline, the costal vein black, 

 other nervures pieeous; costal vein reaching to the middle of the wing, velvety 

 black and considerably thickened throughout; third vein gradually thickened 

 toward tip, not clavate, and free from costa at tip; seventh vein distinct. 

 Length 1.8 mm., wing 1.7 mm. 



Described from a single female specimen collected by H. H. Smith 

 on the Island of Grenada, West Indies, (No. 57.) 



This is the smallest species of the genus which I have seen. It 

 is very distinct and not closely related to any described species.
