The costa of the fore wing is greatly distorted in this species, 
curving outwards near the apex; with this structure is connected a 
contraction of the space between the cell and apex of the wing, and 
a great thickening of the nervures at the end of the cell. Otherwise 
the direction of the nervures differs only slightly from that seen in 
the ¢ A. Amphinome. 
I met with this handsome species only at St. Paulo, where it was 
a common species about tree-trunks on the borders of the forest.

A common and widely distributed species, ranging from South 
Brazil to Guatemala. It has been recorded also as found in Cuba.

A, Arinome, Lucas, Rev. et Mag. Zool. 1853, p. 310. 
This species has been generally confounded with A. Amphinome. 
The difference in colour and markings above is very slight: beneath, 
the red colour of the hind wings is reduced to two basal and a sub- 
marginal row of four or five spots. The shape of the fore wings, 
however, differs a little, the costa being much more curved near the 
apex, and the space between the first and second median branches 
being greater. These characters seem constant ; and I believe it to 
be a species distinct from A. Amphinome. 
A,. Arinome is found in company with A. Amphinome throughout 
the Amazons region.

3. Ageronia Arete, Lucas, Rev. et Mag. Zool. 1853, p. 310. 
Found at many places on the banks of the Amazons and its tribu- 
taries ; Cametd, Obydos, and Ega. It seems also to be common in 
Guatemala, from which country I have seen a long series of examples 
captured by Mr. Osbert Salvin. The species appears to be the same 
as the A. Arete of Lucas (Rev. et Mag. Zool. 1853, p. 310, and Dr. 
Felder, Ein neues Lep. p. 18), who seems to apply Cramer’s name 
to an allied species having many more blue spots on the upper sur- 
face of the fore wings; but Cramer’s species is evidently the one 
which has a clear black space and few spots on the centre of the fore 
wings. The species may also be known by having three red spots
