94 On new Races and Aberrations of Heliconius. 



Tliis subspecies of cydno strong-ly recalls o/dno hroneus, 

 Sticli., from Peru and Eciiafior. It is practical I j idenrical on 

 the fore wing and only different on the hind win^ by the 

 absence of wiiite spots on the margin. iSiicli a form mi^ht 

 easily occur with hroneus as an aberration ; but, on the other 

 hand, it miglit as likely occur as a race and be comparable to 

 cydno zeJinde, which is practically an identical form, but 

 white-banded instead of yellow. Tiiis latter occurs as a race 

 in some western valleys of Colombia, such as the Rio San 

 Juan and Rio Dagua. 



Heliconius elevatus jyerchlora, subsp. n. 



Fore wing above black, with a large part of the basal half 

 of the wing red. On inner margin a red streak detached 

 from the large red area. Adjoining the red area wiihin and 

 above the cell is a largf- roundish \ellow diseal area extendin<i: 

 down beyond vein 2, where it is suffused with black scaling. 



Hind wing with streaking rather heavier than in elevutus 

 elevatus. 



Hind wing below like elevatus elevatus^ except that the 

 peculiar streak inside the costal vein is more strongly yellow 

 and considerably extended. 



Hub. Bolivia. 



The locality is very vague, but the specimen suggests that 

 its origin is correct, as it matches H. melpomene ptnelope^ a 

 typical Bolivian form.
