[LXIX., PT.] Byasa, Moore. B. philoxenus (Gray), the type of 

 this genus, much resembles Pcenasmia dasarada, but the wings 

 are broader and shorter, expanding only 4^ inches. The 

 body is red ; the fore-wings are coloured as in Pcenasmia 

 dasarada ; and on the hind-wings, the tail is short, almost 

 round, and much constricted at the base. Towards the tip is 

 a large white spot, divided in two by a line at its lower end ; 

 there is a red spot on the tail, one on the inner lobe, one at 

 the anal angle, and one on the inner-margin, one on the 

 hind-margin between the white spot and the outer lobe at the 

 base of the tail, and one between the curve beyond this and 

 the spot at the anal angle. 



The larva of B. philoxenus is pale purplish-brown, with 

 several short tubercles on each segment, and a short, broad, 

 white oblique band on the side of the seventh and eighth. 

 The pupa is broad, reddish ochreous in colour, with the head 

 bifid in front, the thorax curved above and beneath, the wing- 

 cases expanded laterally ; and the dorsal segments with folia- 

 ceous lateral appendages. The larva has been found feeding 

 on a creeping pitcher-plant, at an elevation of about 6,200 

 feet ; and the pupa is said to squeak when touched, an un- 

 usual habit in Butterflies, though well known in Manduca 

 atropos, and several other Sphingida. The pupa has not 

 been described. 



[LXXIIL] Menelaides, Hiibner. This genus includes a num- 

 ber of Indo-Malayan and Austro-Malayan Butterflies, most of 

 which are smaller and less peculiarly shaped than those which 

 we have just been considering ; several of them much re- 

 semble the female of Papilio polytes, Linn The type is M. 

 polydorus (Linn.), which is found in the Moluccas and Australia. 

 It has broad, black wings, three or four inches in expanse, and 

 the fore-wings are rayed with greyish-white, the rays towards 

 the hinder angle coalescing into a large blotch. The hind'
