338 Mr. H. W. Bates on the Nymphalinze 
whole order of Lepidoptera. I met with it at different points on the 
Upper Amazons ; always in sunny openings in the primeval forests, 
in hot, gleamy weather between the dry and the wet seasons. Its 
evolutions on the wing are similar to those of the Prepone, and it is 
utterly impossible to capture it except when settled. The first ex- 
amples I saw were attracted by a sweet sap exuding from the trunk 
of a felled tree, where a large number of Cetoniade Coleoptera were 
daily congregated. A dense crowd of other handsome butterflies was 
assembled on the same tree—Prepone, Paphice, Siderones, Gyncecie, 
Ectine, and others; but the frequent shifting of the eager creatures 
had rendered the gorgeous Agriades unusually wary, so that I was 
unable to capture them. When found alone, settled on ordure in 
the pathway, they were less difficult to secure; but it was only on 
three or four occasions, during as many years, that I was so lucky 
as to find the species in such situations. Agrias Sardanapalus is 
closely related to A. Claudia, a rare species inhabiting Southern 
Brazil. The two, indeed, may be considered as local forms of one and 
the same stock ; the Amazonian variety, however, surpasses its South 
Brazilian cousin in splendour.

I found this species only in one locality—namely, at Villa Nova, 
on the Lower Amazons. In the rear of this village the forest is 
traversed by broad alleys, overarched only at rare intervals by trees. 
The sides of the alleys form lofty walls of varied greenery, the 
favourite resort of many handsome species. Agrias Phalcidon de- 
lights to settle on projecting branches, at a height of from 15 to 
20 feet from the ground; and to obtain it I was obliged to lash my 
net to a long pole. When settled it was easy to capture, and so in 
the course of three or four months I obtained a fine series of ex- 
amples. In colour it resembles much Callithea Leprieurti, a common 
insect in the same locality.

One example only, taken at Villa Nova, in company with A. Phal- 
cidon. It differs from this species only in the colours of the upper 
surface of the wings.
