Diptera of St. Vincent (West Indies). 391 



blackish dots and of a more greyish colour ; on the upper side, 

 near the eyes, with an elongated, more blackish triangle. Meso- 

 notum and scutellum greyish-yellowish, with numerous, in part 

 coalescent, small, dark-brown dots, giving the mesonotum a brown 

 appearance ; in the middle may be distinguished two entire, narrow, 

 brown stripes. Pleurte and metanotum densely light-grey, without 

 the dots of the mesonotum. Abdomen opaque, light yellowish-grey ; 

 second segment with a small, semi-oval, coffee-brown spot on each 

 side anteriorly, and in the middle a slender incomplete stripe ; third 

 and fourth segments each with a continuous narrow stripe and on 

 each side a large semi-oval anterior spot united with it, of the same 

 coffee-brown colour ; the gi'ey thus forms interrupted cross-bands, 

 broader on the outer ends ; fifth segment with the spots on the side 

 small, and the median stripe narrow ; in the female marked like 

 the fourth ; fifth segment of the male a little shorter than the pre- 

 ceding. Legs black, greyish-pollinose ; front metatarsi at the base 

 and the basal portion of the four posterior tarsi yellow. Wings 

 lightly tinged ; second section of the costal vein more than twice 

 as long as the third. Length 3-4 mm. 



Numerous specimens. St. Vincent. This species must 

 be closely allied to P. append iculata, Loew, but difiers 

 in lacking the stump of a vein on the fourth vein of the 

 wing.
