120 EHOPALOCEEA. 



Hal. Costa Rica ( Van Patten 5 ), Cache (Bogers) ; Panama, Bugaba, Volcan de Chiriqui 

 (Champion).— Colombia to Bolivia. 



We have a specimen of this species from Peru which we have compared and found 

 to agree with the type of E. telasco in the Paris Museum ; this does not differ from a 

 large series of males in our collection from Costa Rica and the State of Panama. We 

 should employ this name of Lucas were it not practically certain that Fabricius's title 

 P. sisamnus is applicable to the same species, as Mr. Butler has already been at some 

 pains to demonstrate. Judging from Felder's figure, E. pitana is also a synonym of the 

 same insect. 



The male specimens are very constant in their markings, and may be distinguished 

 from the species which follows by the broad black margin to the secondaries, which 

 reaches to the end of the cell and has a sharply defined inner edge. The females vary 

 as to the colour of the common band of the wings : in the majority of cases this is 

 yellow, in others it is white, and we can trace a gradual transition from one into the 

 other. 



E. sisamnus occurs at a lower elevation than most of its congeners, and we have an 

 example from the Isthmus of Panama taken at only a little above the sea-level. We 

 have a pair of this species taken together by Mr. Rogers in Costa Rica.

Hob. Costa Rica (Van Patten 1 ); Panama, Veraguas, Chiriqui (Arce), Volcan de 

 Chiriqui (Champion). — Colombia ; Ecuadoe. 



We have specimens of both sexes of this species, and there can be little doubt but 

 that it is specifically distinct from E. sisamnus, for not only are the discal spots of both 

 wings larger, but those of the secondaries are confluent with the transverse band ; the 

 outer margin is thus very much narrower, and its inner edge is very irregular, almost 

 serrate. The female is very similar to the male ; and so far as our specimens go the 

 central band is white and not yellow, as in the majority of that sex in the allied 

 form. 



We have figured a male and female from Costa Rica.
