is reproduced below the figure)* Rio de Janeiro. 

 Bz. 105£. II- 17. 3. 26. = 350. Rio de Janeiro. (As 

 216, 217.) " Both these Papiliones were caugiit in the 

 forest down the hill." The Brazilian number and later 

 copy without date on 350. 

 *U§.+ 7. 9. 28. 2= 351, 352 (fig. 11 ; Burchell's reference 

 number and date are reproduced to the right of the 

 figure). Between Jaragua and Cavalcanti ; near Rio 

 Maranhao. Fe Guarda Mor. " At twilight in deep 

 shady wood, where we slept this night. Has a hovering 

 motion and settles on the ground. p.m." Brazilian 

 label and later copy on 351. 

 Westwood's list agrees. He separated out 351, 352, evi- 

 dently on account of the character described below. 



The Burchell specimens from Rio Maranhao (351 and 352) 

 show a rufous border on hind wing altogether absent from the 

 long series of this species in the Hope Collection. This 

 character becomes common in Central America. Thus we 

 read in the Rhopalocera of the ' BiologiaCentrali-Americana ' 

 (vol. i. p. 97) : — " The rufous margin, however, is more com- 

 monly seen in specimens from northern localities." The 

 occurrence of the character in a pronounced form in both speci- 

 mens from a locality near the opposite end of the range of the 

 species may therefore indicate a local change or replacement 

 of form in seventy-five years. It is much to be hoped that a 

 traveller who has the opportunity of retraversing this part 

 of Burchell's route may enable us to compare the two 182tf 

 specimens with a good series from the same locality. 



The striking ditierence as regards the hind marginal border 

 of the hind wings between 351, 352, and the specimens from 

 Rio (348-350) is well shown in figs. 11 and 12 on Plate VI.
