314 Miss Cora B. Sanders on the Rhopalocera 



first-named species (37 and 38) and upon one of the last- 

 named (40). But the group also includes another less nearly- 

 related species which Burchell failed to separate. The 

 number 335 is found upon P. hemixanthe (38) and Iletero- 

 scada yanetta (130), indicating that they were taken for the 

 same species on the same day visiting the same flowers, 

 accompanied by Pteronymia sao (53) and Dircenna dero (67, 

 68), both of which were recognized as distinct. Furthermore, 

 in the note-book we find the numbers " 335 . . . (3/7)," indi- 

 cating a second time that the latter, P. euritea (39), was 

 considered to be the same as hemixanthe, and, in this case, the 

 same as II. yanetta also. 



Burchell was able to penetrate the disguise of other ex- 

 amples of mimicry, such as the resemblance of certain Hemi- 

 ptera for the Hymenoptera ; but in the remarkable synapo- 

 sematic likeness between the nearly allied species of Ithomiinae 

 there was nothing to arrest his attention. — E. B. P.] 



Specimens not sexed by Weshvood. His determination 

 agrees. He gives the dates of six additional specimens of 

 euritea which cannot now be found. One of these bore the 

 same date as 42, 43, two the same as 44, 45, one the same as 

 48. One was dated 4. 11. 25 (Minas Geraes, near Nepo- 

 mucena, Francisco Manoel's. The notes show that the 

 specimen might have been captured by tl some tropeiros from 

 the rancho"). One was dated 31. 12. 25 (Rio; on the 

 Corcov^do Mountain, and in the Valley of Laranjeiros). 



Pteronymia sao, Hiibn. 



Bz. 33$. J. 15. 10. 25. ? = 53. Minas Geraes. " Pap[ilio'] 

 cum 335." (As 36. The whole note applies to 53.) 

 Agrees in all respects with Westwood's notes. 



Pteronymia nr. artena, Hew. 



8. 2. 26. ? = 54. Organ Mountains. (As 10-12.) 

 14. 2. 26. S = 55. ,, „ (As 18.) 



Compared with Hewitson's type of artena in the British 

 Museum, 54 and 55 appear to be a less heavily marked form 

 of the same species. 



On 55 Westwood had written " artena but with only a 

 minute white stigma instead of a larger 4-patch," and as 

 regards 54 a difference in venation is alluded to and explained 

 by reference to a rough diagram. The sexing agrees. 



Pteronymia sylvo, Hiibn. 

 12. 11. 25. S = 56. Minas Geraes. " At Mandioca."
