386 THE CANADIAN ENTOMOLOGIST 



apex of the wing brown including the apical half of cells R^ and 

 R^, the apical two-thirds of cell R^ and all of cells M^ and 27id 

 M^; remainder of the wing grayish brown with a large, white 

 cross-band beyond the stigma extending clear across the wing 

 except the apex of cell M ^; a broad cross-band before the stigma 

 and beyond the origin of the sector extending into cell M; a large 

 white blotch in the base of M and the basal half of cells Cu and 

 1st A. Venation: R^ persistent for its entire length; petiole of 

 cell M ^ short, a little longer than m; m-cit short but evident. 



Abdomen dull yellow, the tergites and sternites with a broad » 

 median brown line. Pleural region and sides of the sternites 

 brownish. Hypopygium brown. Male hypopygium with the 

 ninth tergite large, sub-quadrate, the caudal margin with a deep 

 U-shaped notch, this latter medially with a still smaller but similar 

 notch ; lateral angles obliquely truncated. Ninth pleurite complete, 

 large, the ventral portion with dense long setae; outer pleural ap- 

 pendage narrow at base, expanded into a flatted blade which is 

 covered with numerous long stiff setae; inner pleural appendage 

 terminating behind in a scoop-like lobe that is two-toothed, the 

 inner tooth longest and acutely chitinized, the convex lower sur- 

 face with long, pale hairs; anteriorly the blade is white, very flat- 

 tened, the outer edge heavily chitinized, jet-black, the tips ex- 

 panded, in a position of rest lying beneath the ninth tergite. Ninth 

 sternite with a deep, median notch behind which is a membra- 

 naceous area; margin of the sternite adjoining the pleurite 

 setigerous, the posterior portions smooth. 



Habitat. — North Carolina. 



Holotype. — cT, Cranberry, N. Car. (Roland Thaxter.) 



Paratopotype. — cf, in the author's collection. 

 - This species is related to T. angulata Lw, T. penohscot Alex., 

 T. subfasciata Lw., etc., but is separated from all by the structure 

 of the male hypopygium and from the last two species by the com- 

 plete vein R^. The material was heavily infested with the type- 

 material of Entomophthora caroliniana Thaxter. The type and 

 two additional specimens have been placed in the M.C.Z. collec- 

 tion by Dr. Thaxter.
