Nature has so completely disguised this Butterfly in the 

 form and colours of a genuine Papilio, as to have deceived 

 the first entomologist now in Europe, and his most skilful 

 and accurate coadjutator. In the Ency. Methodique we 

 find this species recorded as a Papilio ; whereas it perfectly 

 agrees, in all the details of its structure, with the charac- 

 ters proposed in that valuable work for the genus Pieris. 

 Whether nature has employed this beautiful device to indi- 

 cate the group which next succeeds in her series, or whether 

 she has intended it to point out a strong analogy, are ques- 

 tions which, in our present imperfect knowledge of Lepi- 

 dopterous groups, cannot be answered. 



Of this group we possess several new and highly in- 

 teresting species. It is worthy of remark, that they were 

 all collected in one particular locality, and at the same 

 season. This was during a short residence at Mandioca, 

 the plantation of Dr. Langsdorff, among the woods at the 

 base of the Organ mountains, near Rio de Janeiro. 



We believe this group is restricted to tropical America, 

 where it probably represents the genuine Pieres, (as defined 

 at pi. 69,) of the Old World. The present species is sub- 

 ject to much variation in the size, proportion, and colour of 

 its spots : the white is sometimes pale yellow, and the rosy 

 becomes of a deeper and brighter hue.
