ADELPHA. 307 
We have examined a very large series of this insect not only from Central America 
but also from various parts of the Southern continent, and a selection of these, some 
sixty in number, present no tangible differences that we can detect. We are therefore 
obliged to place Mr. Bates’s name as a synonym of that of Linneus as represented by 
Drury 5. 
A. iphicla is a very common species wherever it is found. In Guatemala it may be 
met with nearly everywhere from the sea-level up to an elevation of 4000 feet. 
23. Adelpha basiloides. (Tab. XXVIII. figg. 15, 16.) 
Heterochroa basiloides, Bates, Journ. Ent. ii. p. 8327. 
Heterochroa lydia, Butl. Ann. & Mag. N. H. ser. 3, xvi. p. 898°. 
Heterochroa lemnia, Feld. Reise d. Nov. Lep. p. 417°. 
A, iphicle persimilis, sed fascia alba anticarum ultra venam medianam extendente distinguenda. 
Hab. Mexico! (Sallé*), Cordova (Riimeli); Guarmmata, San Gerénimo (F. D. G. & 
O. S.); Honpuras?; Nicaragua, Chontales (Belt, Janson); Panama, Volcan de 
Chiriqui (Champion), Calobre (Arcé). 
Mr. Bates’s description of this species was based upon a single female specimen from 
Mexico, from which country we have several other examples, including a male. The 
latter is destitute of the small elongated white spot between the radial nervules of the 
primaries, and thus exactly resembles another male from Calobre in the State of Panama, 
which was examined by the late Rudolph Felder and pronounced by him to belong to 
the species described as H. lemnia, with the type of which he compared it. Felder’s 
description, however, was based upon a female example from Mexico, and attention is 
expressly drawn to the presence of the white spot in question, thus making it certain 
that the names 1. lemnia and H. basiloides both refer to the same butterfly. It must 
be remarked, however, that none of our females from the State of Panama have this 
white spot; but in one of our Guatemalan examples it is almost obsolete, and we are 
therefore unwilling to admit of the existence of two species on so slight and evanescent 
a character. 
A. basiloides, thus considered, probably ranges throughout our region, but we have 
not yet seen specimens from Costa Rica. 
24. Adelpha felderi. (A. falcata, Tab. XXVIII. figg. 13, 14.) 
Heterochroa felderi, Boisd. Lép. Guat. p. 45°. 
Adelpha falcata, Godm. & Salv. P. Z. S. 1878, p. 270”. 
A, iphicle quoad paginam alarum superiorem similis, sed anticis magis falcatis, et macula posticarum anali 
absente ; subtus omnino magis ferrugineis maculis ad basin disjunctis griseis utrinque nigro marginatis; 
serie subapicali macularum unica et intra eam fasciola obscura notatis.
