Latreille's name for this species was based upon Brazilian specimens obtained by 

 Langsdorff 2 . Both Fapilo simplicius and P. dorantes of Stoll were included as 

 synonyms, though the detailed description applies only to the present insect as figured 

 by Hiibner as the male of P. dorantes 1 . Later writers have usually considered 

 Latreille's title to be a synonym of Stoll's P. simplicius ; but this view is quite untenable, 

 for not only is the male of the present species destitute of the costal fold on the 

 primaries, but the secondaries have the outer margin less curved, and the transverse 

 hyaline band of the primaries (though a variable character) is always more clearly 

 defined. Of the other names quoted above, T. sumichrasti of Scudder 5 seems to be 

 certainly referable to E. eurycles ; and G. simplicius of Butler and Druce 6 also belongs 

 here from the evidence of the specimens before us. 



The most characteristic figure of this species is that of Heer Snellen, accompanying 

 his paper on the Lepidoptera of Curacoa 4 . 



As will be seen from our list of localities, this species has an exceedingly wide range 

 over the whole of Tropical America. It is a common insect in Southern Mexico on 

 both sides of the Cordillera from the sea-level up to an elevation of 4000 or 5000 

 feet. 



The male genitalia are almost exactly like those of E. simplicius, so that absence of
