1921] Reinhard: New Species of Texas Tachinide 335 
Vibrissee cruciate, situated on level with oral margin; proboscis moder- 
ately long, palpi black. Cheeks white pollinose, covered with black 
hairs, width about one-seventh the eye-height. Eyes bare. Thorax 
black, white pollinose, marked with four black vitte. Three post- 
sutural and two sternopleural_macrochaetz.. Scutellum black, white 
pollinose on apical half, with three pairs of long marginal macrochaete. 
Abdomen ovate, first segment shining black, segments two, three, and 
four white pollinose on basal three-fourths, distal portions of each shining 
black. First segment destitute of dorsal or lateral marginal macrochaete, 
fourth with a marginal row of five, no discal macrochaete. Wings 
hyaline, veins yellow, costal spine minute, first vein bristly except 
at the base and apex, second vein bristly nearly to the small crossvein. 
First posterior cell open, terminating far before the extreme wing tip. 
Bend of fourth vein distinctly angulated, bearing a long appendage. 
Posterior end of hind crossvein nearer bend of the fourth than to small 
crossvein. Calypteres white, legs black, moderately bristly, hind tibia 
outwardly ciliate, middle tibia with one bristle on the front side near 
the middle. Length 7 mm. 
Habitat.—College Station, Texas. Described from a single 
female specimen collected by the author July 19, 1918. 
This little fly differs markedly from Coquillett’s genotype 
atripennis, which heretofore has been the only representative 
of this genus reported from our fauna. Coquillett’s form is 
black, almost destitute of pollen, and sub-shining, with clouded 
or smoky wings. This species is smaller and covered with 
silvery white pollen. The wings are hyaline. It differs from 
Tothill’s asiatica, described from India, Bull. Ent. Resch. 
Vol. IX, part 1, May, 1918—by the short second aristal segment; 
two sternopleural macrochaete; black palpi; and the bristles 
on the third longitudinal vein extending hardly to the small 
crossvein.
