As Dr. Staudinger, Lis .xi. p. 141 (1808), when cnrapariiig the females of 

 I'. jAzarro, bolivar, and cutorina with one another, did not tiiid any constant 

 character, except size, by which to separate bolirar and cutorina, and mentions 

 as a distinguishing character between cutorina. and pizarro, besides the greater 

 expanse of cutorina, otily a creamy spot situated in cutorina on the underside of 

 the hindwing at the abdominal margin, which character is not constant, we append 

 here a short exposition of those external charat;ters by which the females of the 

 three insects can be recognised. In the Godman collection there is a female 

 received from Staudinger as jnzarro, being labelled " original." Thi.s female is 

 bolivar.
