The above name was proposed for the genus Hyria of Desvoidy, the 
latter name having been previously used in the Mollusca and also in the 
Lepidoptera. Our single species is black, including the palpi; front of 
female as wide as either eye, two pairs of-orbital bristles, and behind the 
posterior pair a pair of outwardly curving macrochetie slightly in front of 
the lowest ocellus; frontal bristles descending to basal fourth of the see- 
ond joint of the antennae, face golden yellow pollinose, cheeks nearly one- 
third as broad as the eye-height, vibrissee on a level with front edge of 
oral margin, ridges bristly on the lowest fourth, antennie nearly as long 
as the face, the third joint one and one-half times as long as the second, 
arista thickened on the basal two-fifths, the penultimate joint broader 
than long; thorax gray pollinose, marked with three black vittz, three 
postsutural and three sternopleural macrochietie, scutellum bearing 
three long marginal pairs, abdomen gray pollinose and with darker 
reflecting spots, hairs depressed, first segment bearing a marginal pair 
of macrochetie, second with two discal and a marginal pair, third with 
thiee discal pairs and a marginal row; middle tibiz each bearing three 
or more on the front side near the middle; wings hyaline, third vein 
bearing two bristles near the base, fourth vein beyond the bend arcuate; 
calypteres white, narrowly margined with brown; Jength, 9 mm. No 
locality, but evidently from the United States. A single female speci-

“This species is referred by Schiner to the Tachina longicornis of Fallen, but judg- 
ing from the description the two species are very distinct, a conclusion already 
reached by Brauer and Bergenstamm.
