REMARKS ON THE DISTINCTIVENESS OF CERTAIN SPECIES OF 
ERYCINA. 
BY A. G. BUTLER, F.Z.S. 
I find in the " Annalea de la Societe Entomologique de France," 
Tom. VI., p. 419 (1837), that Erycina Butes of Clerck, and E. Bhetus 
of Cramer, are placed by M. Morisse as synonyms of E. Licarsis of 
G-odart. 
In the " Grenera of Diurnal Lepidoptera," E. Butes being the 
older name, has been adopted as the specific title, and E. Licarsis 
placed as the synonym, E. Bhetus of Cramer being very properly con- 
sidered as a distinct species. 
Although the Licarsis of Godart may be identical with E. Butes, 
I do not think that the Licarsis of Fabricius can be the same, as his 
description does not suit that insect ; and, moreover, he quotes E. 
Bhetus of Cramer as his species : with regard to the Licarsis of Morisse, 
I am fully convinced, from a careful examination of the two insects, 
that it is quite distinct from E. Butes. 
It is very probable that Fabricius' species may be distinct even from 
Cramer's insect, as the description does not at all agree with his figure ; 
it runs as follows : — 
" Alee anticcB supra atrce, fasciis duabus alhis, suhtus concolores, 
lineola punctoque baseos rubris. Posticce supra atrce fasciis duabus 
obliquis, albis, posterior e obsoleta. Cauda elongata, obttisa, punctis aliquot 
ohsoletis, albis. Ad angulum ani puncta duo rubra. 
Subtus concolores at inter maculas anales p)uncta duo parva cyanea." 
This description more nearly approaches E. Butes than the other 
species. Fabricius, however, makes no mention of the brilliant blue 
which is always found upon the hind-wings of that insect, and his 
description of the anal spots is rather vague. 
M. Morisse evidently considers his Licarsis to be the Brazilian 
form of Butes. He says — 
" Les individus du Bresil ont les bandes blanches, un peu plus 
larges et moins teint^es de bleu," 
There are, however, several specimens of Butes from Rio Janeiro 
in the National Collection, and it is impossible to distinguish them 
from Venezuelan specimens. 
The species figured by Dr. Boisduval, iSp. Gen. Lop. pi. 20, f. 6, is 
undoubtedly the true Butes. 
The following description of the insect will, I think, show how very 
distinct E. Butes and E. Licarsis are from one another : —
