Parasyntorinon lepus sp. nov. (Fig. 1). 



$ Length 2.75 mm. Face narrow, with gray pollen; front brown 

 with brown pollen, wide: antennae black, nearly as long as the head, 

 third joint nearly straight above, rounded below with a pointed tip, 

 excised above so as to have the tip curved upward (Fig. i), arista 

 inserted on the upper edge at the point where the excision begins, 

 shorter than the third joint; orbital cilia Mack above, brown below. 



Dorsum of the thorax bronze black with brown pollen which forms 

 two slight vittae in front with a shining black space between; pleurae 

 black with gray pollen. 



Abdomen dark coppery almost black with a few very short bristles 

 at tip: venter yellowish: hypopygium small, its appendages are a 

 pair of slender, nearly straight, pointed, brownish lamellae which are 

 fringed with hair, back of these a short central filament about the 

 same length as the lamellae. 



Fore coxae yellow with their bases infuscated and with black 

 bristles; middle and hind coxae black; femora yellow, their tops black- 

 ish: tibiae yellowish, the hind pair darkened towards their tips; tarsi 

 darkened from the tip of the first joint; middle femora with a small 

 bristle on each side near the tip: fore femora with delicate hairs on 

 the lower side which are as long as the width of the femora; fore 

 tibiae with a small bristle before the middle; middle tibiae with two 

 strong bristles, one at first and the other at second third: hind tibiae 

 with several bristles; fore tibiae about as long as the first three joints 

 of their tarsi; first joint of fore tarsi with three small bristles at 

 base below, second joint a little widened below, third and fourth joints 

 about equal and without bristles. 



Halteres and tegulae yellow, the latter with black cilia. Wings 

 tinged with gray, slightly brownish in front of the second vein; 

 second and third veins slightly diverging: fourth vein parallel with 

 third and ending in the apex of the wing. 



9 Differs from the description given above in not having the 

 femora blackened above except the hind pair at tip: the front tarsi 

 are plain; the face wider: and third antcnnal joint much smaller.
