Following are the descriptions of one new genus and five new 

 species of Tachinidae taken in the United States, with several 

 notes upon species belonging to this family heretofore described. 



Hypochaeta eudryae, new species. 



Length 5 to 7 mm. ; black, bronzy gray pollinose species. Front in 

 each sex distinctly wider than either eye, frontal vitta varying from 

 faintly yellowish to golden gray pollinose, about three times as wide 

 as sides of front. Ocellar bristles reclinate, frontal bristles descending 

 nearly to the base of the third antennal joint, the sides of the front bear- 

 ing a few scattered bristly black hairs outside of each frontal row. Eyes 

 hairy. First two antennal joints yellowish, the third joint from four to 

 five times as long as the second. Arista thickened on the basal fourth to 

 one-third, the penultimate joint as broad as long. Sides of face about 

 one-fifth as wide as the facial depression, bristles on the facial ridges 

 ascending three-fifths of the distance from the vibrissae to the base of the 

 antennae. Vibrissae inserted on a level with the front edge of the oral 

 margin, palpi and tip of probosis yellow. 



Dorsum of the thorax bronzy gray pollinose, the vittae indistinct. 

 Three dorso-central and two sternopleural macrochaetae. Scutellum 

 bearing a discal pair of macrochaetae, three pairs of marginals and a 

 longer cruciate apical pair. Tibiate yellowish, the middle tibiae on the 

 outer side bearing two or more strong bristles near the middle. 



Hairs of the abdomen depressed, the second segment bearing a pair of 

 median discal and marginal macrochaetae, the third segment a discal 

 pair and a marginal row and the fourth a discal and marginal row. 



Wings hyaline, the apical cell ending but little before the extreme 

 wing tip, the first longitudinal vein bristly almost to the tip, the third 

 vein bearing two or three bristles at its base. Calypteres whitish. 



Described from one male and one female taken at Oswego, 

 New York, June 11, 1897, one female from the White Mountains 

 (Morrison) and one female (Holotype) reared from Eudryas 

 grata, April 12, 1911, from a larva taken at Newton, Mass. All 

 of the material placed in the collection of the U. S. N. M. from 

 which it was kindly loaned to me by Mr. Frederick Knab, with 

 the exception of the holotype which was reared at the Gypsy 

 Moth Laboratory. 



Holotype: Cat. No. 20175 U. S. N. M. 



Hypochaeta townsendi, new species. 



Differs from //. eudryae as follows: Length 6 to 7 mm. Abdomen coxae, 

 femora and tibiae reddish yellow, first two joints of the antennae, palpi
