collected Ly W. J. Barchell in Brazil. 317 



" All of this date were from off plants, mostly up the 

 Valley of Catumbi." 

 The specimen was named by Westwood epidero.

 Burchell wrote " 475 . . . (340) " in his Brazilian note-book, 

 indicating his recognition that the four specimens 67-70 

 belonged to the same species.

 between Jundiahy and Capivary. " Iter faciendo." 

 Burchell's manuscript labels are reproduced to the right of 

 the three figures on PI. VI. (5-7) to which they respectively 

 refer. That accompanying fig. 6 was written in Brazil, the 

 others in England. 



Westwood, in his complete list, mentions two individuals 

 captured on 28. 10. 25. He also gave a list of captures on a 

 label attached to 70, and this agrees with the numbers and 

 dates here recorded. It is therefore probable that the former

 viduals. On 68 Westwood had written " This is the only 

 individual with the veins of H. W. suffused with black." 

 The specimen is shown on PI. VI. fig. 6, where the feature 

 mentioned by Westwood can be clearly seen when comparison 

 is made with figs. 5 and 7. Westwood does not note the 

 sexes. He employs the name dero only. 



[I have followed H. W. Bates in regarding D.rhoeo, Feld., 

 as a form of dero, differing " only in the greater breadth and 

 irregularity of the dusky black border of the hind wing, 

 especially in the female, and in the nervures which traverse 

 the disk of the same wing being of a yellowish colour instead 

 of black. In the female the discocellulars and the terminal 

 parts of the median branches are accompanied by dusky 

 streaks." D. dero, on the other hand, " has the hyaline
