C. atreo similis, sed anticis fere omnino cyaneo suffusis et margine posticarum externo ab angulo apicali ad 
angulum analem late aurantiaco distinguendus. 
Hab. Mzxico18, Cordova (Hége) ; Guatemata, Quirigua, Polochic valley, forests of 
Northern Vera Paz and Retalhuleu (Ff. D. G. & O. 8.), Rio Naranjo and Mirandilla 
(Champion) ; Honpuras 2? 
As already stated, this species is closely allied to C. atreus, and takes the place of that 
butterfly in Southern Mexico and Guatemala. The most obvious difference is in the 
orange band of the secondaries, which here occupies the whole outer margin of the 
wing, including the apical angle; the primaries, too, have the blue gloss more exten- 
sively spread. 
C. wranus, besides being found in Southern Mexico, is not an uncommon butterfly in 
the hottest forests of Guatemala. We found it in such places, amongst the Indian ruins 
of Quirigua, in the Motagua valley, throughout the dense forests of Northern Vera Paz, 
on the track to Peten, and also in the forests of the Pacific coast, where also Mr. Cham- 
pion has recently met with it in several places. | 
Its habits are like those of its congeners. It flies a few feet from the ground in the 
forest, going a short distance when disturbed, and settling on the stems of the trees. 
ERYPHANIS. 
Eryphanis, Boisduval, Lép. Guat. p. 57 (1874). 
The members of this genus, of which EF. automedon, Cr., is the typical species, were 
placed in the genus Caligo until Boisduval separated them in 1874. This step seems 
to be justified, as a comparison of the following characters with those of Caligo will 
show :—The body is rather slender, the prediscoidal cell being, as in Caligo, quite 
small; there is a denuded patch on the submedian nervure of the secondaries of the 
male, but no central tuft of hairs; the male, too, has a peculiar oval patch of long 
closely felted scales near the anal angle. The coxa of the front leg of the male is 
rather slender and shorter than the femur. The tegumen of the male has a long 
slightly curved slender hook, and on the ventral surface on either side a rectangular 
lobe, the ventral edge of which is smooth, without serrations or spur as in Caligo; the 
harpagones are long, slender, and simple, without lobes, but strongly dentate on their 
dorsal edge. 
Hight or nine species are now known of the genus, which is a purely Neotropical one 
and spread over the whole of tropical America as far south as Brazil. Of these three are
