Genus Basilarchia 



is most common in the region where the insect is found. The 

 species mimicked is Danais cbrysippus, of which at least three 

 varietal forms or local races are known. The American butterfly 

 conforms in the female sex to the typical D. cbrysippus, to which 

 it presents upon the upper side a startling likeness. On the 

 under side it is marked much as the male. Expanse, $, 2.50 

 inches; ?, 3.00 inches. 



Early Stages. — What has been said as to the early stages in 

 the description of the genus must suffice for the species. But 

 little is as yet accurately known upon the subject. 



The range of H. misippus is southern Florida, the Antilles, 

 and the northern parts of South America. It is not common on 

 this side of the Atlantic, but very common in Africa, tropical 

 Asia, and the islands south as far as northern Australia.

 pitted with large hexagonal cells (see p. 3, 

 Fig. 1).
