Our description of this variable species is taken from a male from Nicaragua agreeing 

 closely with Cramer's figure, and this form is found wherever the species occurs. With 

 these we find a very dark form in which the black colour is increased at the expense of 

 the diaphanous spots. This may be a seasonal variety, for it is so universally spread 

 with the more typical insect that we cannot believe the differences are of specific value. 

 Mr. Kirby's Entheus marshalli 4 from Trinidad is somewhat intermediate between the 

 two forms just referred to. We have precisely similar specimens from Guatemala and 

 elsewhere, and we have no doubt that it is only a variety of P. vitreus. 



P. vitreus is not a common insect at the extreme northern limits of its range, and we 

 have seen but few specimens from Vera Cruz and Guatemala, and those all from the 

 hot lowlands of the eastern side of the mountains. It becomes more abundant as we 

 proceed southwards, and in South America must be one of the most numerous in 

 individuals of the Hesperiidee. 



The male genitalia have the end of the tegumen rather tumid, cleft at the end, 

 the arms diverging, and each terminating with a double or appendiculate claw ; the 

 scaphium is well developed ; the harpes are drawn to a blunt point, the dorsal edge is 

 raised at the highest point in a truncate lobe, separated from the edge by a shallow 

 fissure on the proximal side and a deeper one on the distal side. (See Tab. LXXXI. 

 fig. 26.)

Mr. Watson properly restricts this genus to the type E. peleus and its immediate 

 allies, numbering in all about seven species. The sexes, so far as we know them, of 

 most of the species are so different in their coloration that from the earliest times males
