in a minute puncture; in front of wing-base a group of 8-10 stout 

 black setulae ; scutellum with about six marginal setula^, disc with many 

 microscopic hairs. Abdomen almost parallel-sided, the surface with 

 very weak hairs. Legs strong, fore femora slightly stouter than hind 

 pair, one stout thornlike bristle at middle on ventral surface and an- 

 other midway between it and the apex ; other femora unspined ; hind 

 tibiae without strong hairs ; basal joint of hind tarsi as long as next 

 three together; fifth joint twice as long as fourth, without ventral 

 bristles ; claws rather short, equal in length, and w'ith a small median 

 inner tooth. Third vein to three fourths the wing-length, first to two 

 fifths the length of third; media forking at cross vein; cubitus forking 

 almost directly below cross vein. 



Length, 3 mm. 



Type locality. Modern, Col., May 28 (T. D. A. Cockerell). Named 

 in honor of the captor. 



This species has not been taken in Illinois.

Ceratopogon venustulus Williston, Trans. Ent. Soc. LoncL, 1896, p. 278. 

 Beszia vennstnla (Williston) Malloch, Jour. X. Y. Ent. Soc, Vol. 22, p. 282. 



Described from St. Vincent, British West Indies, and not subse- 

 quently recorded. 



4. Bezzia feavitarsis Malloch 



Bez2ia flavitarsis Malloch, Jour. N. Y. Ent. Soc, Vol. 22, 1914, p. 283. 



This species w^hile almost the same in color as cicnfata Malloch is 

 readily separated from it by the different bristling on the legs and by 

 the venation. In flaritarsis there are 4-5 spines on the apical half of 

 the ventral surface of the fore femora only, the other pairs being nude 

 except for a short spine at the apex on the anterior surface. The tibial 

 bristles are also much less numerous and less conspicuous than in dcu- 

 tata. The third vein extends to less than three fourths the wing-length. 



Originally described by the writer from female specimens obtained 

 at Monticello, 111., June 21, IQ14, on the bank of Sangamon River. In 

 addition to this localitv, specimens have since been obtained in Illinois 

 by the writer at Muncie, July 5. Mr. Hart collected specimens, July 

 IS, 1914, from two Michigan localities, namelv. Little Bear Lake at 

 Grand Junction, and South Haven. 



At Little Bear Lake Mr. Hart took a single male specimen. It dif- 

 fers from the female in having the flagellum of the antenna,^ yellow ex- 

 cept on the apical third, the antennal plumes golden yellow, the entire 

 length of antenna nearlv twice that of head and thorax combined, the 

 tibiffi more stronglv setulose, the third vein to about two thirds the 

 wing-length, and the first to middle of third.
