the third intermediate broad and black. Beneath almost the only difference from 
P. feronia is the pale saffron ochreous hue of the hind wings. These differences are 
apparent when comparing Mr. Bates’s types with specimens of P. feronia; but with a 
more extensive series before us than Mr. Bates had access to we find that most of the 
distinctions alluded to above are of an unstable character. Asa rule, however, the 
submarginal ocelli of P. guatemalena have grey and not white pupils. The under 
surface of the secondaries too is suffused with buff instead of being pure grey. 
P. guatemalena is abundant in Mexico and Guatemala, where it is found in the 
hotter districts. It also occurs in Costa Rica and Nicaragua, but in Panama its place 
is taken by P. feronia.

The upper surface of the wings of P. iphthime have a strong general resemblance to 
those of P. feronia. ‘They are, however, of rather a more dingy hue; beneath all the 
dark marks are of a rich brown instead of being nearly black. Mr. Bates described 
this species from specimens obtained by us in Guatemala}, where it is by no means 
uncommon in the lowlying forests on both sides of the Cordillera. It is also found in 
Southern Mexico and, doubtless, in the rest of Central America, but no specimens have 
yet reached us from Costa Rica. Thence it spreads through Colombia to the valley of 
the Upper Amazons, where Mr. E. Bartlett found it on the Ucayali. In South Brazil 
a closely allied species, P. epinome, takes its place.

If, as we believe, the insects belonging to this genus are separable from Batesia, the 
name Pandora, having been already used several times in zoology, cannot be retained 
as their generic term. Mr. Kirby in his synonymic catalogue has already pointed this 
out; but he gets over the difficulty by placing all the species in the genus Latesia. 
Besides having the radial nervures of the primaries parallel as Mr. Bates has indicated, 
instead of the upper radial being curved as in Batesia, there are differences in the
