Group C. The Microdice Group 



In tliese species the aedeagus is gradually arched with the distal 

 end hoodlike, this appearance caused by a very broad incision; there 

 is a distinct subapical tooth at either side of this hood which is some- 

 what flattened either dorsoventrally or sometimes lateralh^ 



Hind wings above as in Groups B and D. Hindwing below with 

 white or yellow ground color; with or without a submarginal series of 

 sagittate markings; v.'ithout orange streaks tlu-ough middle of in- 

 terspaces; with a white spot on lower discocellular vein (the chief 

 difference between this group and Groups C and D) or as mentioned 

 above with nearly the entire v/ing white.

 group.
