11. Male hypopygium with the notch of the ninth tergite V-shaped, the lateral 

 margins with small denticles (Fig. 30, B) ; posterior margin of inner disti- 



stvle at base with an acute spine entomophthorae 



Male hypopygium with the notch of the ninth tergite transversely U-shaped, 

 shallow, without lateral denticles (Fig. 30, M) ; posterior margin of inner 



dististyle not spinous trivittata 



12 Male hypopygium with basistvle produced dorsad into a long slender process 



stylifera 

 Male hypopygium with basistyle simple, not produced 13 



13. Praescutal interspaces with brown setigerous punctures entomophthorae 



Praescutal interspaces not dotted with brown 14 



14. A dark spot in cell C opposite midlength of Rs ; white band before cord 



extending unbroken from veins R to Cu ; male hypopygium with tergite 

 deeply notched medially, the lateral angles produced caudad into long acute 



points (Fig. 30, C) huron 



No distinct dark spot in cell C near outer end; white band before cord more 

 or less interrupted by a dark clouding in posterior portion of cell R 

 adjoining vein M, restricting the band to isolated areas in cell M and at 

 midlength of Rs ; male hypopygium with caudal border of tergite truncate, 

 with a small quadrate median notch, at base of which is a small denticle 

 (Fig. 30, A) 15 



15. Pale crossband beyond cord incomplete, extending about to midlength of 



cell Ms ; antenna! flagellum clearly bicolorous, light yellow, the basal en- 

 largements black huntsmaniana 



Pale crossband beyond cord complete, attaining the wing-margin in cell Mx ; 

 antennal flagellum indistinctly bicolorous, brownish yellow to brown, the 

 basal enlargements still darker, brownish black to black angulata

Antennae relatively long, if bent backward extending to beyond 

 base of abdomen; in cases, the antennal flagellum is so dark that the 

 bicolorous nature is almost lost. Centers of praescutal stripes re-
