68 Dr. Horsfield's Descriptions of 



referred to Jones's drawings with the name of Papilio Cocyta : the very 

 concise specific character has nothing but the following remark for its 

 illustration : "affinis carte P. Bella at difFert alis haud falcatis, ecaudatis 

 et dentatis." Now it appears from the preceding details that our insect 

 should have rather been compared with P. Cocytus, with which it was 

 originally associated. This oversight of Fabricius has called forth a very 

 severe censure from the authors of the Encyclopedie. 



The description of the P. J^ymphalis Cocyta of Fabricius, which is 

 now ofiered with the name of Aconthea Coeytina, has been made from 

 individuals brought by Sir Stamford Raffles from Sumatra. The name 

 has been modified in order to prevent a collision with the insect disco- 

 vered in Siam, to which the name Cocytus was applied among the Danai 

 festivi. The Banksian cabinet of insects, so frequently cited by Fabricius, 

 and now deposited in the Museum of the Linnean Society, still contains 

 the individual from which the description of the P. Cocytus appears to 

 have been made. The specimen, although in an indifferent state of 

 preservation, exhibits the peculiarities of this species, the most promi- 

 nent of which are the falcate wings, and the posterior brown band on the 

 under surface of the fore wings: but my object is not at present to 

 illustrate the Papilio Cocytus of Fabricius; I trust however, that the 

 preceding details, with the figure accompanying them, will procure a place 

 for the Aconthea Coeytina in the systematic catalogues.
