them in company on the flowers of Cep. occidentalis, Anona grandi- 
flora, &c., and on the muddy roads. Its flight is more powerful 
than that of Philenor. About equally diffused throughout the 
Union. 
P. Thoas. This certainly is not the same as the Brazilian 
species. I have a specimen from Mexico exactly like the 
N. American ones. This is Cramer’s Cresphontes. It is a rare 
and quite southern species. I took but three or four in Florida. 
It flies rapidly in the pathways of the woods, sailing with its 
wings expanded. It alights on the ends of projecting branches or 
on a projecting dead twig, sitting with its wmgs expanded, droop- 
ing, as we set lepidoptera in England, or rather more so ~~ ~~. 
than we commonly depress them; quite as much as the line 
above. I never saw it close its wings over its back. I saw it often 
in the streets of Savannah, Geo. It seemed common there. Abbot 
gives the larva on the orange. I found it on the Thorn-ash, or 
Stink-ash of the Florida people; Zanthoxylon fraxineum (‘fragrant 
groves of Zanthoxylon,’—Bartram). Boisduval’s figure of the larva 
is, I think, pretty correct. 
I used to be much amused with the groups of butterflies in the 
wet places in the roads. I have seen Turnus, Philenor, and Troilus, 
Col. Philodice, Tereas Lisa, Melitzea Tharos, Argynnis Cybele, 
Polyommatus Competor, Danaus Archippus (rarely so), and two 
or three Hesperiz, all clustered together on a few yards of mud. 
I have seen too in Illinois, in the autumn, Colias Philodice and 
Ceesonia, Terias Nicippe (?) and Lisa, and Callidryas EKubule, in 
groups, literally of hundreds (the first named insect generally 
making 42 of the company), on a space not 6 feet square. The 
Philodices sit with their wings over the back, in rows, quite close 
together, in fact sometimes touching each other, thirty or forty in 
arow. These things I hardly dare tell, for people won’t believe them. 
I have put a (2) to the Nicippe. I think there are two species 
confounded under this name, but am not sure which is the right 
one.
