oil this account it is easily recognized. Tliis species has been taken 

 during the past summer as follows: Logansport, June 25; Negreet, 

 May 19; Cameron, August 23; New Orleans, August 29. A discussion 

 of this species and its habits was given on a previous page. 



TABANUS AMERICANUS Forster (American Horsefly). This is 

 our largest Xorth American species. It is restricted in its distribu- 

 tion to the southeastern United States. The color is red, the wings 

 are hyaline with a narrow front border which is pure brown. Its bite 

 is severe, but the species does not usually appear in numbers suffi- 

 cient to make it as serious a pest as some of The smaller species. 

 Specimens were taken m .Montgomery, .lune 29.

TABANUS BENEDICTUS Whitney (Brown Horsefly). This 

 species was but recently described from specimens taken in Missouri. 

 It is a large species, about the size of /'. airalux, which it resembles 

 somewhat, but the body is dark-brown and' the wings are subhyaline. 

 It does not appear to be as abundant as some of the other species, 

 but has been reported as injurious to driving-horses. Taken at Crow- 

 ley, June 17; Montgomery, June 29: Frierson, July 14. 



TABANUS SULCIFRONS Macquart (Autumn Horsefly). This is 

 somewhat smaller in size than the species of Tnhiiinis named above 

 The thorax is marked with narrow gray stripes, the abdomen is red- 

 dish above, with a median longitudinal row of white triangles, and 

 the wings are subhyaline with a number of small brown spots. It 

 is distributed generally over eastern North America and is one of the 

 most abundant nnd annoying pe'sts of the Family Tabanidae. It is 

 one of the late-appearing species, being abundant when many other 

 species have nearly disappeared. Speeimehs were taken at Lecompte.
