XX. On the Papilio Telamon of Donovan, with Descriptions 

 of two other Eastern Butterflies. By J. O. Westwood, 

 F.L.S. 



[Read 3rd March, 185!.] 



The Papilio Telamon, figured by Donovan in his " Insects of 

 China," has up to the present time continued to be known only 

 by the figures in that work, no specimen existing in any Con- 

 tinental or British Cabinet. Specimens of the insect having how- 

 ever been recently sent from Shanghai, in China, by R. Fortune, 

 Esq., of which both sexes have been obtained for the British 

 Museum Collection, I have been enabled to examine the species, 

 and find that it belongs to a genus distinct from Papilio, and the 

 other genera of Papilionidce, differing at once from Papilio in its 

 elongated palpi. It approaches very near to Thais Cerisyi in 

 general form, but in that insect the antennae are much more cla- 

 vate, with more numerous articulations, the space between the 

 second and third branches of the post-costal vein of the fore 

 wings is much more elongated, the palpi much more hairy, the 

 hind wings without the small prediscoidal cell, and not furnished 

 with a single elongated tail. The female is destitute of the ab- 

 dominal pouch of Doritis. In the arrangement of the veins of 

 its wings it is nearly similar to Teinopalpus ; the middle disco- 

 cellular vein in that genus is however nearly straight, and not 

 angulated, the hind wings in both genera have the small pre- 

 discoidal cell, but the upper disco-cellular vein in Teinopalpus is 

 much more transverse, and the lower one is short, oblique, and 

 almost continuous with the space between the second and third 

 branches of the median vein ; whereas in Telamon the upper disco- 

 cellular vein in these wings is very oblique, and the lower one nearly 

 transverse. The antennae of Teinopalpus also differ considerably 

 from those of Telamon, the basal portion being quite cylindrical, 

 so that the joints are not distinct (as they are in Telamon, each 

 being slightly thickened at the tip) ; the clava of the antennae 

 is very distinct in Teinopalpus, and the front of its head is pro- 

 duced into a thick conical hairy tuft. The following are the 

 characters of the new genus which is accordingly required for the 

 reception of P. Telamon.
