specific characters; we therefore prefer to use the name C. eurylochus for our specimens, 
including those from South Brazil, which Dr. Felder proposed to call Pavonia bra- 
siliensis *. Should the Central-American insects ultimately prove to be distinct, 
M. Deyrolle’s title C. galba may be applied to them. This name was attached to two 
plates, representing the upper and underside, which were published in the ‘ Revue de 
Zoologie’ for 1874, but unaccompanied by any letterpress. We have, however, a 
specimen from M. Deyrolle marked as the type of C. galba, and with the locality 
‘“‘Colombie” attached to it. This specimen presents no material differences from our 
Central-American ones. 
C. eurylochus appears to be a rare insect in Guatemala, as the only specimens we 
possess from that country are one taken by ourselves, in the year 1861, in the valley of 
the Motagua, and another recently sent to us from San Juan, in the Polochic valley, by 
Mr. Champion. We have never seen it in the vast collections sent us from Vera Paz 
and elsewhere. In Nicaragua and thence to South America it is much more abundant.

This species seems most nearly allied to C. ewrylochus, but is usually a much smaller 
insect. The mottling of the undersurface is not so uniformly distributed, and is 
altogether interrupted between the costal and the largest ocelli of the secondaries. 
This part of the wing is rich brown, with strong black very sinuated lines. The 
character is well shown in Dr. Felder’s plate®. C. otlews was originally described from 
Venezuelan and Colombian specimens!. We now trace it through Central America as 
far north as Mexico (whence we have a single specimen) and Guatemala, where we 
obtained a male in the forest near Yzabal in September 1861. It must be rare in 
Mexico and Guatemala, as no other specimens have come to us from there. Nor does 
it seem much more common elsewhere, as the three Panama specimens mentioned by 
Mr. Bates in his paper on Butterflies of that district? are the most we have from any 
one place. Its home seems to be the northern parts of Colombia.
