Foiialc. — Fulvous, slightly shining. Head brown on vertex ; an- 

 tennae fuscous ; face and palpi pale fulvous. Disc of mesonotum sub- 

 opaque, with very slight indications of pale pruinescence ; pleurae shin- 

 ing. Abdomen slightly brownish, shining. Legs, including the coxse, 

 pale reddish yellow ; knees of hind legs narrowly dark brown, apical 2 

 joints of tarsi slightly brownish. Wings clear, veins yellow. Halteres 

 fulvous. 



Eyes separated by about a fifth the width of head ; antenna about 

 as long as head and thorax combined, second joint of flagellum very 

 slightly longer than its diameter, the other joints becoming successively 

 longer to the eighth, apical 5 about 4 times as long as broad. Mesono- 

 tum covered with very short closely placed hairs, the usual longitudi- 

 nal rows of hairs almost indistinguishable ; 4-5 black setulose hairs in 

 front of each wing-base ; scutellum with a few marginal setulose hairs. 

 Abdomen slender, not noticeably spatulate, the apical segment very lit- 

 tle broadened. Legs slender, without setulae, hind tibial hairs weak ; 

 basal joint of hind tarsi slightly longer than the next 3 joints together ; 

 fifth joint without ventral spines ; tarsal claws rather small, subequal, 

 each with a short tooth near base on inner side. Third vein to five 

 sixths the wing-length ; first, to two fifths the length of third ; media 

 forking slightly before cross vein ; cubitus forking below cross vein. 



Male. — Slightly darker in color than the female. Antennal plumes 

 brown. 



Length of antenna slightly exceeding that of head and thorax to- 

 gether. Hypopygium small. Legs as in female except that the tarsal 

 claws are distinctly smaller in comparison with the fifth joint. Third 

 vein to two thirds the wing-length; first, to near middle of third. 

 Otherwise as female.

Type locality, Urbana, 111., July 7, 1914, on store windows in town 

 after the lights were turned on (C. A. Hart and J. R. Malloch). Mr. 

 Hart obtained 2 females at Little Bear Lake, Columbia, Mich., July 

 15. 1914. 



3. Probezzia pallida Malloch 



Proheszia pallida Malloch, Proc. Biol. Soc. Wash., Vol. 27, 1914, p. 138. 



This species was described from the female only, and I have not 

 yet been able to obtain the male. Muncie and Monticello, 111., are the 

 only localities from which I have seen this species, and June 28 is the 

 latest date on which it was collected.
