Owing to a typographical error the length of the species is given in 

 the original description as 8 mm. instead of 3 mm. I have seen a male 

 specimen of this species, submitted by Prof. O. A. Johannsen, from 

 Ithaca, N. Y., and another taken at Swarthmore, Pa., submitted by Mr. 

 Cresson. The male agrees with the description of the female as given 

 by Coquillett in being entirely yellow, in having the tarsal claws small 

 and subequal. and in venation. The antenna is one and a half times as 

 long as head and thorax together, the plumes are yellow with brownish 

 apices, and the legs have many long setulose surface hairs. A female 

 from Polk Co., Wis. (Aldrich), has the setulose hairs on the legs 

 weaker than those of the male. 



Originally described from three females taken at Biscayne Bay, 

 Florida, by Mrs. A. T. Slosson. The species probably occurs in Illinois,

I have not seen this species. It was originally described from 

 Alaska and has not been subsequently recorded. I have some doubt as 

 to its generic position, and have included it in the key given for species 

 of Johannscnomyia as well as in the key to species of the present genus.
