distance from humeral vein to wing-tip, third vein to two fifths of the 

 distance from apex of first to wing-tip ; distance from cross vein to 

 apex of first, measured along costa, one third of that from apex of 

 first to apex of third ; last section of first vein little longer than the 

 cross vein connecting it with third ; the black spot on the posterior side 

 of apex of third vein takes the form of a slight callosity of the wing 

 membrane ; petiole of media as long as the lower branch of cubitus, the 

 latter forking in vertical lines with the apex of first vein and well be- 

 vond the cross vein. 



Fcuialc. — Color as in the male but the black marks on the abdo- 

 men generallv less coalescent, and those on the legs and wings more 

 distinct. 



The antennae are much more slender than those of the male, and 

 the joints more elongated, their combined length ecjualing two thirds 

 the length of the bodv, surface hairs numerous, but short and weak ; 

 head as in male except that the proboscis is stronger. Abdomen stouter 

 than that of male, the surface hairs weaker and paler. Legs similar 

 tc* those of male, differing principally in having the fifth tarsal joint 

 more elongate and with a transverse pair of bristles near its base on 

 ventral side ; tarsal claws unequal in size, the inner one being less than 

 half as large as the outer. In other respects agrees with male.

Illinois localities : L^rbana — a large series of specimens, represent- 

 ing both sexes in about equal numbers, taken by sweeping amongst 

 undergrowth and trees on the banks of the old channel of Salt Fork at 

 the fair grounds. May 20 and July 4, 1914; Monticello, June 28, and 

 Mahomet, August 6, 19 14, under same conditions as above (C. A. 

 Hart and J. R. Malloch). 



Originally described from Virginia. Male not hitherto described. 



Palpoiiiyia (S/^hccroiuyas) biniacula Kieffer* agrees in almost 

 every detail with the present species. The localities given for biniacula 

 are Calcutta and N. Bengal. P. viridivcntris Kieffer (1. c, p. 203) 

 also belongs to this genus but is more closely allied to viridis Coc{uillett. 

 The type locality for this species is Dawana Hills (1000 feet), Lower 

 Burma.
