This widely distributed and common Tropical-American insect is very variable in 
colour ; and in some specimens the lines crossing the primaries are very distinct, while 
in others they are almost obsolete. We are now able to trace the species as far north 
as Mexico, where it appears to be not uncommon. Walker has described the species 
three times, and on each occasion he placed it in a different genus. I fail to detect 
the slightest difference between his types. 
Examples were captured by Mr. H. H. Smith in various localities in Mexico, between 
April and October 1888.
