This common and very variable insect is universally distributed in the warmer parts 
of America, and I have a series of about one hundred specimens before me. In no one 
locality is it constant in size or colour; and I am quite unable to separate even the 
most extreme forms from the typical one. The females are much more subject to 
variation than the males. The Mexican specimens are the smallest, and agree best 
with those from Paraguay; the largest examples come from the tropical lowlands of 
South America. I cannot but think that we have only one variable species, and not 
five, as Mr. Butler states, P. Z. S. 1878, p. 488.
