Though a single male specimen of this species was included in Dr. Van Patten’s 
Costa-Rica collection, Messrs. Butler and Druce believed it to have been obtained in 
Colombia*. It can hardly be doubted, however, that the species does occur in Costa 
Rica, as we have the excellent testimony of the late Mr. Belt of its presence at 
Chontales, some distance further north. We also have specimens from the State of 
Panama, sent us direct from that country; and the late James M‘Leannan informed us 
that individuals might not unfrequently be seen flying high in the opening of the 
trees cut for the Panama railway. Owing to the great difficulty of catching them, 
he only secured a single specimen. 
There is some variation in Central-American individuals of this species. Those from 
Nicaragua seem quite similar to the usual type of the Colombian insect. The specimen 
from the Panama railway is a small one with rather short primaries, and the white band 
on the secondaries much narrower. These differences, however, are of no specific value. 
We have one female specimen from Nicaragua which is of the yellow type as figured 
by Hewitson?; but we believe the form with the blue shade also occurs there. This 
form is well figured by Dr. Felder 3. 
[Morpho sulkowskii, Westw. This species was mentioned in Messrs. Butler and 
Druce’s collection of Costa-Rica butterflies with doubt as to the origin of Dr. Van 
Patten’s single specimen. We have no confirmation of the occurrence of this species 
within our limits; and though it may possibly be found there, being a Colombian 
insect, we hesitate to include it formally in our list. ] 
d. Wings rich metallic blue; primaries rather falcate, with the apex black.
