Hob. Mexico 12 (Beppe z % Jalapa (P. JD. G.), Orizaba {H. J. Elwes, Salle), Oaxaca 

 (Fenochio). 



This fine species was first figured by Hiibner, in the third, incomplete, volume of his 

 ' Sammlung exotischer Schmetterlinge,' from Mexican specimens — one which he calls 

 Heraclides aselepius, male, the other, a female, Euphoeades garamas, both in reality 

 representing females, the latter a dimorphic female of the former. The male was first 

 made known by Hopffer, who described it under the name of P. abderus, from Mexican 

 specimens obtained by Deppe, which are now in the Berlin Museum. For some time 

 we were under the impression that P. abderus and P. aselepius were distinct species, 

 and that P. electryon of Bates was referable to the former ; but with our present series 

 we are convinced that P. abderus and P. aselepius are male and female of the same 

 species, which has a purely Mexican domicile, P. electryon being slightly different and 

 inhabiting a different country. 



P. aselepius is probably restricted to the forest-regions of Southern Mexico. We 

 have no positive evidence that it occurs on the mountain-slope of the western range.

P. asclepio similis, fascia mediana per cellulam attenuata costam haud attingente, fascia posticarum extrorsum 

 minus profunde serrata ; posticis subtus lunulis internis nigris introrsum vix fulvo marginatis, lunulis 

 submarginalibus fulvis saturatioribus baud flavo limbatis. 



Hob. Guatemala, Central valleys 1 , Polochic valley (P. B. G. & 0. S.), Purula 

 (Champion). 



During our visit to Guatemala in 1861-62 we obtained a single male specimen of 

 this species, which served as the type of Mr. Bates's description l . A few others were 

 subsequently sent us from the valley of the Polochic, and Mr. Champion captured two 

 males in the upland forest-region near Purula. Unfortunately the female is unknown 

 to us at present, and we are therefore unable to say whether it possesses submarginal 

 yellow lunules to the secondaries, as in P. aselepius, or is without them, as in P. syedra. 



The differences between P. electryon and the male of P. aselepius are slight, but, so 

 far as we can see, quite constant,
