(J ? . This form only has been dissected by us: the above description of the 

 strnctnre of the sexual armature applies, theref(U'e, to the present subsi)ecies. The 

 third antemediau line of the forewing, above, is undulate, the brown marginal area 

 of the upjierside does not reach binder angle, and that of the underside is of nearly 

 the same tint from tlie apex of the forewing to the anal angle of the hindwing. The 

 dot at the base of the forewing is mostly double, or the dots are fused to one; 

 seldom is one of them absent.

 antemediau line almost straight, first discal line less straight than in i/iri/// ; brown 

 marginal area extending to hinder angle, its inner edge almost evenly curved ; 

 marginal area of underside of both wings not distinctly browner than disc, except 

 below apex of forewing and at anal angle of hindwing. Structure of the eighth
