easily scared away. The Paph'ice and Prejwnce are exactly simi- 

 lar in manners. The larvae, I have no doubt, are of the same 

 form as that of Apatura Iris. I have bred a Prepona, the larva 

 was naked, and the head of similar shape to Apatura. These 

 genera and their allies form a very natural group in the Nympha- 

 lidce. 



CaU'ithea Sapphira. — At the end of the dry season (end of De- 

 cember) this butterfly became very scarce on the wing, and the 

 specimens were worn and faded. About the 12th of January its 

 larvae appeared in great numbers in the woods, feeding upon the 

 leaves of young trees of various species. The larva is very 

 beautifully banded with metallic violet colour and orange-red, 

 and bristled with long, branching spines of the metallic colour, 

 two of which, arising from the head, are three times the length of 

 those arising from the body. At the beginning of February they 

 generally changed into the pupa state, and about the middle of 

 the month the perfect butterfly appeared, in beautiful dress and 

 in great profusion, but only for a few days, for, with the continua- 

 tion of the heavy rains in February and March, it disappeared 

 again. I reared both the C. Sapp/iira and the C. Leprieurii. The 

 larva of the latter is in the same way as that of the former spinose, 

 but its colours are different, being banded with bluish black and 

 greyish pallid green. The pupa is distinguished from that of 

 Sapphira by having a few black spines. 



The flight of C. sapphira is slow in comparison with all other 

 Nymphalidce. It settles frequently, and seeks the foliage of trees 

 at a height of from ten to twenty feet from the ground. The 

 female settles lower, but is very wary, and apt to escape into the 

 thicket on being disturbed. The male is quicker in flight, and 

 very rarely descends within reach of a moderate-sized net. 



The Catagrammce are more rapid and arrowy in flight than the 

 Callithece. They repose on the trunks of trees, and are very 

 much attracted by odours and filth on the ground, also by the 

 sugary sap on the trunks of standing trees ; they are much more 

 wary than the Agrias, but still, in certain states of the weather, 

 are not so difficult of approach as many other kinds of Ni/mpha- 

 Udes, as the Epicalice and Cybdeles, especially C, Caslalia, which 

 is the wariest butterfly I ever knew. 



Cybdelis (1) Pharsalia, Hewhs. — This is not a Cyhddis ; it is 

 a new generic form coming near Callithece. Its habits and mode 

 of flight are very much like those of the Callithece. It frequents,
