former with H. primularis of the latter. We see no way at present of accounting for 
this singular state of things. : 
Of the present species we have figured one of the type specimens, a male from 
Choctum in Northern Vera Paz, Guatemala.

H. galantho similis, sed litura alba anticarum angustiore, posticis albo marginatis (venis divisis); subtus ut

Hab. Panama, Chiriqui, Santa Fé and Calobre (Arcé), Lion-Hill station (IZ‘Leannan’). 
—CoLomBiA, Frontino. 
A single example, which we now figure, was the type of Mr. Bates’s description of 
this species. This was sent us by the late James M‘Leannan from his station on the 
Panama railway. He subsequently sent us a few other examples; but the species does 
not appear to be so abundant on the line of railway as further to the westward in the 
State of Panama, whence we have received a good supply of specimens. In this 
direction it spreads as far as the neighbourhood of Chiriqui; but in Costa Rica its 
place is taken by H. galanthus. In Colombia it occurs near Frontino in the Cauca 
valley. 
There is some slight variation in members of this species, chiefly affecting the inner _ 
margin of the white band of the primaries. The submarginal band, too, of the secon- 
daries is nearer the margin in some specimens than in others; but in all it is a 
feature by which they may at a glance be distinguished from H. galanthus. 
Note.—The Colombian Heliconius cydno is included by Messrs. Butler and Druce* 
in their list of Dr. Van Patten’s Costa-Rica collection, on the faith of a single specimen 
contained in it. In default of further evidence of the occurrence of the species within 
our limits, we are inclined to think that this specimen had been accidentally introduced 
into the collection from another source, as seems to have happened in other instances.
