typical atratus. The series before me referable to nantuckensis 

 show the following distribution: 



N. H. Rochester, Sept. 8 (A. M. Wilcox). 

 Mass. Boston, July 10 (H. M. Parshley); Cohasset, July 24 

 (Owen Bryant); New Bedford and Horse Neck Beach, Aug. 

 9 (Dr. G deN. Hough) ; N. Tisbury, July 21 (Dr. J. A. Cush- 

 man); Tuckerneck, July 21 (Dr. G. M. Allen); Muskeget, 

 July 7 (W. S. Brooks); Hyannisport, July 4, Woods Hole, 

 July 25, and Wellfleet, Aug. 16 (C. W. Johnson). 

 R. I. Block Island, Aug. 28, 1891 (A. P. Morse). 

 In this same region, typical atratus has been taken at the follow- 

 ing places: Brookline, Auburndale, Sherborn, Framingham, Fal- 

 mouth, Chatham and Woods Hole, Mass. 



Tabanus atratus var. fulvopilosus var. nov. 



This is another interesting variety which Osten Sacken refers 

 to as follows: "The most remarkable variety, however, I received 

 from Florida (Indian River, E. Palmer; Haulover Beach, March 

 12-14, Messrs. Hubbard and Schwarz); the thorax on each side 

 bears a fringe of golden yellow hairs, not a trace of which is visible 

 in ordinary specimens. I have four specimens from Florida, and 

 two from some other southern locality not nearer defined, which 

 show this peculiarity." 



Fine examples of this variety were collected by Mr. S. E. Cas- 

 sino at Orlando, Fla., in April, and by the writer on Anastasia 

 Island, St. Augustine, Fla., April 21, 1919. I also collected a speci- 

 men at Avalon, N. J., July 19, 1891. Another specimen was cap- 

 tured at Cold Spring, near Cape May, N. J., June 24, 1903, by 

 Mr. H. L. Viereck. The specimens from New Jersey have wings 

 of a uniform dark brown approaching nantuckensis. A specimen 

 of nantuckensis (from Nantucket) shows a slight trace of yellow 

 pile above the base of the wings and lower edges of the post-alar 

 callosities. 



Another interesting variation of the more typical atratus, repre- 

 sented by two males and a female from Anastasia Island, Fla., 

 April 1'2-19, has the black of the wings confined to broad margins 

 along the veins, leaving subhyaline spaces between, giving the 

 wings a striped appearance. A male of nantuckensis from Muske- 

 get is similarly marked on the anterior half of the wings.
