The females described, of which two were received with the males from the Rio 

 Sucio, seem to belong here, though they are scarcely separable from the same sex of 

 A. zabulon.

There is a good deal of confusion as to what is the true Hesperia vitellius, Fabricius, 

 the type of which is said to come from the West Indies. We have four male 

 examples, including both sexes, from St. Thomas, which seem to us to answer the 

 brief description of this insect, and with these we associate two males from Guatemala 

 and a female from the Amazons. Hubner's figures show very clearly the characteristic 

 angulation of the inner edge of the dark costal border of the secondaries, as well as 

 the wider interrupted band at the anal angle of these wings. 



Two males have been dissected, one from St. Thomas and one from Guatemala, and 

 we find that the genitalia in both are similarly formed. Dr. Staudinger has lent us a 

 pair of P. insularis, Mab., from St. Thomas. A specimen from Duenas is figured. 

 For the genitalia of the male, see Tab. XCIV. fig. 13.

We have seen twelve examples of this species, including one from Southern Mexico 

 and three from Chiriqui, all males. It is a close ally of A. perfida, Moschler, from 

 Colombia, but differs from it in having the fuscous margins on the upperside broader, 

 and there is an interrupted longitudinal stripe of the same colour along the median
