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 macrochjcta' slightly in front of 

 the lowest ocellus ; frontal bristles descending to basal fourth of the sec- 

 ond joint of the antenna', face golden yellow pollinose, cheeks nearly one- 

 third as broad as the eye-height, vibrissa? on a level with front edge of 

 oral margin, ridges bristly on the lowest fourth, antenna', 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 vitta', three 

 postsutural and three sternopleural macrochtetie, scutellum bearing 

 three long marginal pairsi, abdomen gray i)ollinose and with darker 

 refiecting spots, hairs depressed, first segment bearing a marginal pair 

 of macrocha^tie, second with two disc al aud a marginal i)air, third with 

 t hiee discal pairs an d a marginal row; middle tibia? each bearing three 

 or nu)re on the front side near the middle; wings hyaline, third vein 

 bearing two bristles near the base, fourth vein beyond the bend arcuate; 

 calyj)teres white, narrowly margined with brown; length,!) mm. No 

 locality, but evidently from the United States. A single female s[)eci-
