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 certe P. Bella at differt alis haud falcatis, — 
et dentatis.” Now it appears from the preceding details that our insec 
should have rather been compared with P. Coc, ytus, with which it its 
originally associated. ‘This oversight of Fabricius has called forth a very 
severe censure from the authors of the Encyclopédie. ary 
The description of the P. Wymphalis Cocyta of Fabricius, itch 3 is 
now offered with the name of Aconthea Cocytina, 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 Cocytina in the systematic catalogues.
