Bz. 13. 3. 2Q. = 1291. Rio de Janeiro. 



19. 3. 26. = 1292. Rio de Janeiro. " In the valley of 



Catombf." A Westvvood's label reads, " Heliconia 



Eucrate [Isabellina] V The parentheses are Westwood's. 



21. 3. 2Q. = 1293. Rio de Janeiro. " Along the Carioca 



Aqueduct." 



"YVestwood's list records one other specimen of this date. 

 10. 12. 29. = 1294. Paid. Data erroneous. 



This date is omitted from YVestwood's list and from his 

 labels on 1287 and 1290. It is erroneous, not only on the 

 evidence of Westwood's records, but because the date indicates 

 a locality considerably to the north of that in which all the 

 other captures of this species were made by Burchell, as well 

 as to the north of the locality (South Brazil) given by 

 Stichel 2 . 



In attempting to reconstruct Burchell's original labelling, 

 assistance may be derived from 104, a specimen of Mechanitits 

 poh/mnia, now bearing the date 30. 10. 25, indicating a 

 locality considerably to the south of that in which the other 

 individuals of this species were captured. Reasons were 

 given in Ann. & Mag. Nat. Hist., April 1904, p. 320, for 

 believing this label to be probably erroneous, and it was, 

 moreover, suggested that the date on one of the additional 

 specimens of M.polymnia, recorded by Westwood, viz. 3. 3. 28 

 or 10. 12. 29, was originally borne by 104. Now the latter 

 of these dates is at present erroneously borne by the JJeli- 

 conius 1294, to which it may have been accidentally trans- 

 ferred from 104. If we furthermore suppose that 1285 (type 

 form) bore the date 30. 10. 25, now on 104, and 1294 (variety) 

 bore 29. 10. 25, now on 1285, the labelling of these three 

 specimens would agree with Westwood's records and with 

 the probable localities of both Heliconius and Mechanitis. 



Westwood's list and labels on 1287 and 1290 give the 

 following dates not now to be found on any existing specimen 

 of H. narccea : — 30. 10. 25, Minas Geraes (see above) ; 

 1. 4. 26, Rio. Two other additional specimens are referred 

 to under 1290. 



Opposite to the data " No. 580 ; 30. 10. 25 ; 8. 2. 26 ; 

 7. 3. 26; 19. 3. 26," Westwood had written in the list: 

 " Jleliconia Eucrate {Isabellina) : al. ant 8 , dimid . basali fulvo 

 fascia obliqua nigra ad apicem cellulse — macula subapicali 

 alba." Similarly opposite to the data "29. 10. 25 ; 7. 11. 25 ; 



1 H. W. Bates's isabellinus is placed by Stichel as a subspecies of 

 numaius, Cram., allied to narccea. 



- Bahia and Espinto Santo are the actual localities in S. Brazil cited 

 by Stichel.
