This species varies slightly. Dr. Staudinger informs me that his specimen from 
Chiriqui was named by Guénée; it is darker in colour than the figure.

This genus includes a large number of species, chiefly American. It is well repre- 
sented in North, Central, and South America, and also in the Antilles. Many of the 
species are extremely variable; and it is more than probable that when they are better 
known the sexes of some of them will prove to have been treated as specifically 
distinct.

This variable species is very common and widely distributed in North and Central 
America and the Antilles; but I have not as yet seen a specimen from south of the 
Isthmus of Panama. The large number of examples before me vary from almost black 
to pale brown, but in no one locality do they appear to be constant in colour or mark- 
ings. We have not as yet received from within the limits of our fauna a specimen 
agreeing with the typical North-American H. edusa, all our numerous examples 
belonging to the variety /unata.
