and A. myron, the costa of the secondaries at the base is clothed with long projecting 

 hairs, which are more conspicuous in the male than in the female. The genitalia of 

 the males of A. vitellius, A. myron, and A. rolla differ considerably from those of the 

 other species, as will be seen by a reference to our Plate. The sexes of A. myron and 

 A. zabulon have the wings very dissimilarly coloured on the upperside. The females 

 of all the species appear to be very much rarer than the males. The genus is repre- 

 sented all through Tropical America. Pamphila perfida, Moschl., from Colombia, 

 belongs here. According to Mr. Scudder and Dr. Skinner, the North-American 

 A. hobomok (Harris) has two forms of female — one very like the male, the other a dark 

 form (Hesperia pocahontas, Scudd.) closely resembling the same sex of A. zabulon.

We refer three males from Mexico and Guatemala with some hesitation to this 

 species. They agree, however, with others of the same sex from Pennsylvania and 

 Florida in our collection, and also with Edwards's fio-ures. 



A. delaware differs from A. vitellius (Fabr.), as understood by us, in having the 

 primaries of the male more pointed at the apex and without a distinct fuscous 

 patch beyond the end of the cell. The females, from Florida, have the base and outer 

 margins of both wings broadly marked with fuscous, the primaries also having a fuscous 

 streak at the end of the cell. The male of A. delaware is also very like the same sex 

 of the South-American A. perfida (Moschler), but it is paler, and has a narrow fuscous 

 margin to the primaries, the veins in these wings are also much less distinctly marked 

 with fuscous. A specimen from Rincon is figured. 



We have examined the genitalia of a North- American specimen only see
