of the historical basis for the nomenclature (used extensively in the

tem here and in future systematic work.

Description 
Fore and hind wings similar in size and shape, but markedly 
different in venation. 
Fore wing: length 35-55 mm, and apparently not coriaceous; cos- 
tal area broad in basal region, SC simple, terminating in C; R 
parallel to SC, terminating at wing apex; RS originating from base
