Genus Dircenna 
Early Stages. — Unknown. 
Reakirt says that this butterfly occurs about Los Angeles, in 
California, and the statement has been repeated by numerous 
authors, who have apparently based their assertions upon Reakirt’s 
report. I have no personal knowledge of the occurrence of the 
species within our borders. It is very abundant, however, in the 
warmer parts of Mexico and Central America, and it may possibly 
occur as a straggler within the United States. 
Genus DIRCENNA, Doubleday 
Butterfly. - Medium-sized butterflies, for the most part with 
quite transparent wings. The most characteristic features of this 
genus, separating it from its near allies, 
are the thread-like front feet of the fe¬ 
males,furnished with four-jointed tarsi 
(Fig.83), the very hairy palpi, 
and the wide cell of the hind 
wing, abruptly terminat¬ 
ing about the middle of the 
wing. Furthermore, in the 
male sex the hind wing is 
strongly bowed out about fig. 83.— 
the middle of the costal Fore leg of 
margin, and the costal vein klugii, 9, 
tends to coalesce with the greatly 
subcostal about the middle. 
Early Stages. — Very little is as yet 
known about the early stages of these 
insects, and what has been said of the 
characteristics of the caterpillars and 
chrysalids of the subfamily of the Ithomiinse must suffice us here. 
This genus numbers a large array of species which are found in 
the hottest parts of the tropics of the New World. They fairly 
swarm in wooded paths amid the jungle of the Amazonian region, 
and no collection, however small, is ever received from those 
parts without containing specimens belonging to the group.
