James S. Hine. 



Tabanus annularis n. sp, 



E\-es hairy. General color nearly black, thorax very hairy and 

 obscurely striped, abdomen dorsally with the posterior margin of each 

 segment narrowh^ reddish gray, wings hyaline with the veins dark, 

 first two segments of the antenna and tip of the third dark, remainder of 

 the third segment brown with a prominent basal process. Length, 10 

 to 12 nuillimeters. 



Male — Eyes very distinctly hair^^ legs black with the exception of 

 the tibiae, each of which has the basal half or more reddish brown. 



Female — Eyes plainly hairy, front of nonnal width, sides parallel, 

 frontal callosity as wide as the front and shining black, ocelligerous 

 tubercle present, denuded; otherwise front and the face gray pollinose.

Holotype male, one other male and a female in the Ohio 

 State University collection, taken at Ocean Springs, Mississippi, 

 April 18, 1916, by Max Kisluik. The female is a poor specimen 

 of rather diminutive size. Both sexes have the color of the 

 body exactly the same.

 basal process of the third antenna! segment. In this respect the 

 species agrees with hirtioculatus Macquart.

 in others, wings brownish hyaline; abdomen brown with a dorsal black 

 stripe and venter darkened towards the apex. Length, 14 millimeters. 



Female — Frontal callosity nearly square not so wide as the front, an 

 unconnected line above and ocelligerous tubercle shining black. Other- 

 wise front and the face gray pollinose. 



Male — Like the female in coloration, head small, eyes distinctly 

 hairy.
