apical pale areas are joined along the inferior border; 4-6 

 similar to 3, but in each the basal and subapical pale areas are 

 separated by the lateral extension of the subbasal dark area, 

 this separation progressively longer (i. e., the pale areas below 

 more reduced) posteriorly; 7-10 as in dorsal view, 8-10 

 with the lower border paler than the dorsum, most distinct on 

 9 and 10. Superior appendages brown, paler at base, darken- 

 ing sometimes to black at apex; inferior appendages dull 

 yellow. 



Legs light brown or gray, very lightly clouded or shaded 

 with darker; a more or less distinct brown subapical area on 

 each femur. 



Wings clear or brownish tinged; stigma dark brown or 

 black, covering from two minus to two plus cells ; two to two 

 plus postquadrangular cells in the front wing and two minus to 

 two plus in the hind wing; postnodals in front wing 15 to 

 18, in hind wing 14 to 16; in the front and hind wings the 

 arculus is distal to the cubito-anal cross-vein from .3 to .5 

 mm. ; in the front wing the anal vein separates distad to the 

 cubito-anal cross-vein from about .4 to .6 mm., in the hind 

 wing from .6 to .8 mm. 



Female. — Head similar to that of the male, especially the 

 . younger and paler males, and variable as in that sex; the 

 frons above is never black, but varies from light to very dark 

 brown, except at the lateral extremities which are black; the 

 vertex is largely brown, a black area on each side opposite 

 the antenna, a black area in front of and on either side 

 of the median ocellus, between the antennae, and a black 

 occipital crest are always present ; the pale area on either side 

 of the median ocellus varies in extent and clearness but is 

 always present; the same is true of the median pale area in 

 front of the median ocellus, except that it is apparently want-
