whereas in A helva it is much smaller and more isolated. The female is very different 

 from that of A. helva. It may be noted that in A. myron the wings in both sexes are 

 similarly coloured beneath, though they are very dissimilar above. A pair from 

 Atoyac are figured. The two males we have dissected are respectively from Fortin, 

 Mexico, and Roraima, Guiana; these agree perfectly in the structure of the genitalia, 

 see Tab. XCIV. fig. 22.

Through the kindness of Dr. Staudinger we have been enabled to examine the types 

 of P. helva and P. sethos, and we have little hesitation in treating them as belonging 

 to one species, the chief difference being the narrower and more elongate shape of the 

 second spot of the oblique series on the primaries in the female, and the more distinct 

 subapical spots in this sex. We have seen a female from Coatepec agreeing with 

 P. helva, and we have males from Chontales, Chiriqui, and Santa Marta agreeing with 

 P. sethos. The base of the costa of the secondaries in both sexes is clothed with very 

 long blackish hairs. The type of P. sethos, a male, from Chiriqui, and a female from 

 Coatepec, agreeing with the type of P. helva, are figured. The genitalia of two males 

 have been dissected, see Tab. XCIV. fig. 27.
