more brown and hind ones darkened beyond the base of the 
femur; wings distinctly yellowish, venation light brown. Front 
quadrate; median line and ocellar tubercle distinct; four large 
postantennal bristles, the lower ones slender, close together; 
upper ones widely separated, as far from the median line as 
from the eye-margin, well above the lower ones and on a level 
with the inner bristte of the lower reclinate row which is close to 
the eye margin and directly below the lateral bristle; next row 
of four equidistant and distinctly bowed downward medially. 
Antennae small, arista nearly bare, scarcely one half longer than 
than the head-height. Palpi with strong bristles below. Cheeks 
each with two downwardly directed bristles and a row of several 
smaller ones extending toward the antenna. Mesonotum sub- 
shining, with one pair of dorsocentral bristles and a strong bristle 
at the lateral margin just anterior to them; scutellum one-half 
broader than long, with only two bristles. Propleura with a few 
scattered minute hairs and three bristles at the base of the an- 
terior coxa; mesopleura finely bristly above, with one large 
backwardly directed bristle inserted at the upper posterior 
angle. Abdomen with the third segment elongated, one-half 
longer than the second which has a small tuft of long bristles at 
the sides; fourth segment not abbreviated; ovipositor pale yel- 
lowish. Anterior tibise without setulse, their tarsi slender; mid- 
dle tibise weakly setulose inside the seam and with a row of 
setula3 outside the seam on the basal half; posterior ones siniiliar, 
but the setulse are moderately strong in both rows, numbering 
seven or eight and being over half as long as the width of the 
tibia. Wings very narrow; costal vein extending well beyond 
the middle, with very short and fine, closely placed bristles; 
first section as long as the second and third together, the third 
nearly half as long as the second. Third vein running nearly 
parallel to the costa, but approaching it more rapidly beyond 
the fork which forms a very acute angle; fourth vein curved 
only at the base, ending no nearer to the wing-tip than the fifth; 
fifth, sixth and seventh nearly straight. Halteres yellowish 
white.
