Hob. Minas Geraes? Coll. Saunders. 



The most beautiful Pericopis I have seen, and unlike any 

 other species. 



Genus Phaloesia, Walker. 

 Phaloesia Olympia, n. sp. 



Alae supra nigro-fuscse : anticae cella discoidali basique nitide caeru-

Hah. Brazil. Coll. Saunders. 

 A lovely new species. 



Amongst the other Pericopides in Mr. Saunders's collection

 described : — 



'■'' Antlwmyza Salvinij''' Felder, MS. Polochic Valley (Salvin). 

 " AntJiomyza mimica^'' Felder, MS. Upper Orinoco. Mimics 



Heliconius Timareta. 

 " Anthomyza htstrio,-^ Felder, MS. Villa Nova [St. Paulo, in 



B.M.]. Mimics Melincea Mcdus. 



P. Salvini comes nearer to P. Kenara than to any other 

 species, but differs considerably, in the front wings especially. 



P. mimica is a fair imitation of Heliconius Timareta^ and 

 consequently is not nearly allied to any other Pericopis. 



P. histrio is allied to P. angulosa. 



It is an interesting fact, in connexion with the dispute re- 

 specting the date of publication of the second volume of the 

 ' Voyage of the Novara,' that the plates on which the above 

 species are figured are all antedated. I received a letter from 

 the late Dr. Rudolph Felder, dated Weidling, near Kloster- 

 neuburg, August 5, 1869, in which he says : — " Provisional 

 copys of our Heterocer. plates you will receive soonly by Mr.
