ing ill one specimen ; in older specimens the area between the 

 ocelli is largely black. i\ntenna and profile similar to the 

 male. 



Prothorax dingy white to lemon yellow, patterned as in the 

 male, the hind lobe as described for the palest males; the 

 posterior half or more of the middle lobe is more or less in- 

 definitely stippled brown or black. Propleuron white to light 

 yellow. 



Thorax patterned exactly like that of the male and only 

 slightly paler, in fact a bright colored female may be brighter 

 than a dull colored male, but in no females does the yellow 

 of coxae and under parts become as bright as in the brightest 

 males. 



The abdomen also is practically as described for the male, 

 except that it is slightly duller, the pattern not quite as defi- 

 nite ; segment 2 has the low^er lateral border pale, not black 

 edged as in the male; 8-10 instead of being progressively 

 darker posteriorly, as in the male, are progressively paler; 

 in some specimens 8 and 9 are more or less black on the sides. 

 Appendages unusually long, .8 to .9 mm., slender, dull yellow 

 or light brown at base, shading apically to dark brown. 



Legs as described for the male. 



Wings and stigma as in the male ; the postquadrangular 

 cells in the hind wings very variable, in the front wings, 15. 

 wings have two postquadrangular cells, and 10 wings have two 

 plus, but in 25 hind wings, 19 have from one to one and a half 

 cells, 6 have two minus and 9 have two cells; postnodals 15 to 

 18 in the front wing, and 13 to 16 in the hind wing; relations 

 of the cubito-anal cross-vein to the arculus and the separation 

 of the anal vein from the posterior border as in the male.
