Choctum (Hague). 
The eyes in this species are destitute of hairs, and the palpi more densely hairy than 
in almost any other Luptychia that we have examined. These and other less important 
characters induced R. Felder to place E. squamustriga in a genus by itself; and we 
should be glad to adopt this division, were we able to trace any well-defined group of 
insects possessing such characteristics. But the hairiness or smoothness of the eyes, SO 
far as we have been able to see, is subject to considerable variation in Euptychia, and 
still more so the hairiness of the palpi; so that we have not been able to make any 
satisfactory divisions resting upon these features. The neuration of the primaries 
places E. sguamistriga with the insects which here precede it, where it may rest 
pending a thorough examination of the whole genus. 
This species is apparently a rare one, as we have received but a single specimen from 
Guatemala, the type of Z. zabdi, now figured. In Mexico, besides the type obtained 
by Lieut. v. Hedemann at Huahuapam, near Cordova, Felder speaks of two other 
males in his collection captured at Cuernavaca. 
The names given by R. Felder and Mr. Butler to this butterfly were proposed within 
a few weeks of each other. The paper containing the description of the former author 
was read, but probably not published, prior to the issue of the part of ‘ Lepidoptera 
Exotica’ containing the description and figure of the latter. As Mr. Butler in his 
corrections places his name, £. zabdi, as a synonym of E. squamistriga, we follow him 
in so doing.

valleys (fF. D. G. & O. S.' & H. Hague); tNicaracua (Mus. Brit.2**). 
Though closely resembling E. pieria, this butterfly appears to be sufficiently distinct 
from that species to be recognizable. Besides the slight difference in the position of 
the second subcostal branch of the primaries, the chief differences observable are the 
position of the ocellus of the anal angle of the hind wings beneath (which in £. similis
