There is a small $ of this species at Tring without locality and with the

Castnia (Nasca) pelasgus (Cram.) 



Papilio pelasgus Cramer, Pap. Exot. vol. iii. part xvii. p. 16. pi. ccii. fig. D (1779) (Surinam), 



Messrs. Houlbert & Oberthiir treat pelasgus and unijasciaia Felder as 

 distinct species, while they describe a third form from the Upper and Peruvian 

 Amazons as fulvofasciata. The Tring Museum possesses 1 pelasgus and 1 unv- 

 fasciata (type), and whereas it would require a long series from all localities of 

 aU these 3 forms to ascertain definitely their exact status, I shall treat them 

 for the present as distinct.
