head Lake, Maine, July 14 and 19, 1907 (C. W. Johnson), in 

 the collection of the Boston Society of Natural History. 



Paratypes, Princeton, Maine, July 12, 1909; Franconia, New 

 Hampshire (Mrs. A. T. Slosson) ; White Mountains, near 

 Glen House (Dr. Geo. Dimmock) ; Ricketts, North Mt, Penn-

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 

 Adams, June 14, and Mt. Everett, Massachusetts, June 28; 

 Darien, Conn., June 10; Philadelphia, June 30; Edge Hill, 

 June 5, and North Mt., Pennsylvania, June 8 (C. W. J.). 



The First Fossil Anthomyid Fly from Florissant 



(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 uliyinosa ; 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 Hyctodcsia Iciiconun) ; thorax ele- 

 vated, scutellum prominent, dorsal thoracic macrochaetae very large, 

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

 hairs apparently practically as in Hyctodcsia, 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 P- long, the arrangement very 

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