purplish iridescence and forewing and hindwing with considerable 

 reddish-brown mottling on undersides. Hindwing light reddish 

 brown, paler basally; cilia ferruginous apically, gradually becoming

Male genitalia (slide 10368) : In addition to the larger size of the 

 genitalia of holographa, they differ from brachystigma by the sharp 

 angle formed between the uncus and posterior margin of the tegumen. 

 In brachystigma the lateral edges of the uncus are confluent with the 

 posterior edge of the tegumen.
