Readily separated from B. badia by its less prominent an- 

 tennal process, the black middle and posterior femora, and 

 the large yellow triangular markings on the third abdominal 

 segment, especially in the male. It is a species belonging to 

 the Canadian zone, while B. badia practically belongs to the 

 transition zone and is only occasionally taken in areas fre- 

 quented by a few species found in both zones. 



Thirteen specimens of B. badia show the following distri- 

 bution: Northeast Harbor, Maine, July 19, 1909 (Dr. C. S. 

 Minot) ; Franconia. New Hampshire (Mrs. Slosson) ; Man- 

 chester, Vermont, June 9; Auburndale, June 15, North

(Dipt.). 



By T. D. A. CocKERELL, Boulder, Colorado. 



Anthomyia (sens, lat.) atavella n. sp. 

 Length nearly 6 mm., of wing 4.25; robust, bristly; the head, thorax 

 and legs were apparently black ; the abdomen as preserved is warm 

 reddish, with the sutures pallid, it was probably brown ; wings per- 

 fectly clear, veins dark. Top of head with large bristles directed for- 

 ward, as in Lispa uliginosa; palpi about 480 /* long and 80 broad near 

 end, feebly clavate, with bristles not longer than diameter of palpus 

 (these palpi are essentially as in Hyetodcsia leucorum) ; thorax ele- 

 vated, scutellum prominent, dorsal thoracic macrochaetae very large, 

 one near base of wing over 640 t^ long, the long bristles and short 

 hairs apparently practically as in Hyetodesia, but the precise arrange- 

 ment cannot be made out ; four very large macrochaetae can be seen 

 in the longitudinal subdorsal row. before the scutellum ; abdomen with 

 thinly scattered bristles, the largest in a row near the hind margins of 

 the segments, these being about 350 /^ long, the arrangement very 

 nearly as in the Muscid Myiospila meditabunda; legs bristly, the hind
