Parasyntormon 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. 1), arista 
inserted on the upper edge at the point where the excision begins, 
shorter than the third joint; orbital cilia black 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 antennal joint much smaller.
