collected hy W. J. Burchell in Brazil. 15 



14. 12. '2Q. ? = 1460. Cabat^o. No mention is made of 

 this date in any of BarchelPs records. But on Dec. 13tli 

 we find, both in the Cat. Geog. and in the Cat. pi. Braz., 

 that he was on the lower slopes of the Serra de Cubat^o ; 

 while on Dec. 15th the same two Catalogues state that 

 lie was at Rio das Pedras : hence it is probable that he 

 was back again at Rio das Pedras on Dec. 14th, perhaps 

 engaged in arranging his botanical and zoological 

 collections. 

 Westwood's " Catal. A. 9 " is on specimen, and his list 

 agrees with this label. 



It is very difficult to determine, from the nature of the 

 paper, whether the label borne by this specimen is English 

 or Brazilian : for though it has the wiiitish colour, it does not 

 exhibit the signs of age of the latter type of paper. Inas- 

 much, however, as it is a little larger than the average Bra- 

 zilian label, it seems probable that it is made of a different 

 type of English paper from tiiat ordinarily employed by 

 Burchell — most of the English labels having been written on 

 paper of a greyish tint. The same difficulty has been expe- 

 rienced with regard to the labels on 1458, 1459, 1462, and 

 1471. The two former, however, being a great deal larger 

 than the ordinary Brazilian label, are almost certainly 

 English, while the others are probably also English, for the 

 same reasons that were stated for 1460. 



Both spots are distinct, the lower being subtriangular, with 

 its apex directed towards the base of the wing. It is inter- 

 esting to note that the lower spot takes this form in all the 

 Burchell specimens that possess a well-marked rectangulated 

 band on the upper surface. Moreover, Hiibner clearly repre- 

 sents this feature as well as a portion of the band in his 

 figure of A.pellenea in the ' Zutrage zur exotischer Schmetter- 

 linge ' \ The degree of triangularity varies greatly in 

 ^eZ/e/jea-like as well as in other specimens, and in a large 

 number of cases the spot loses the triangular shape altogether, 

 and becomes rectangular or ovoid &c. I conclude, therefore, 

 that this character is of no more value in separating A. pel- 

 lenea from A. thalia than is the upper surface band. All 

 distinctions founded on pattern alone seem to break down ; 

 and {{pellenea be really separate from thalia, the evidence must 

 rest on structural characters as yet insufficiently investigated, 

 or on the results of breeding. 



The upper surface rectangulated band is only faintly indi- 

 cated, but as the hind wing is almost totally denuded of
