NORTH AMERICAN DIPTERA. 305 



My specimens agree closely, and are doubtless of the same species 

 as the South American ones. I have a specimen from Minnesota 

 that has no spines on the anterior part of the second and third seg- 

 ments. It may be B. hicolor Macq., as " pas des soies au milieau des 

 segments" seems to be the only difference indicated in the description.

Hab. — Eastern States. 



A rather common species. Wiedemann's description of C. maero- 

 cera (Auss. Zw. ii, 290, 16, Tachina) applies very well to this species ; 

 V. d. Wulp has compared North and South American specimens, and 

 believes them to be different (Tijdschr. v. Ent. xxvi, 13). 



fSipliona cristata Fabricius. 



Specimens from the New England States agree so closely with the 

 descriptions of this European species that a comparison is needed. 



Roselia, Plagia, Ifl.yobia. 



These European genera, not hitherto recorded from North America, 

 I believe I recognize with sufficient certainty in specimens from the 

 Eastern States. 



MEIjAXOPHRYS gen. uov. [TacMninarum.) 



Head in profile nearly square. Front long, gently inclined, broad 

 in the female, about one-third of the width of the head in the male ; 

 in the male with a single row of not very strong bristles reaching to 

 but not below, the base of the antennae. Face in profile very gently 

 retreating, nearly vertical and straight, deeply excavated, and with 

 sharp, smooth, free and bare lateral ridges ; sides of face broad in 

 the side view, wholly bare. Oral opening elongate ; palpi slender, 

 proboscis not elongate. Cheek nearly horizontal, gently convex 

 below, broad, bare ; fringed along the lower border with a row of 

 fine bristles, not perceptibly stouter, or longer in front and not as- 

 cending on the side ridges ; epistoma but very little projecting. An- 

 tennae elongate, the third joint in the male four or five times as long 

 as the second, in the female shorter ; arista thickened, not elongate. 

 Eyes rather small, elliptical, thinly pilose in the male (I do not dis- 

 tinguish any hairs in the female). Occiput convex. Abdomen 

 short, broad, convex, bristles not abundant nor strong. Front tarsal 

 joints of female slightly dilated. Neuration as in Echinomyia ; pos- 

 terior cross-vein gently bisinuate, posterior angle of first posterior 

 cell rectangular and with a stump of a vein.
