portion scarlet ; except on eighth segment, where the base 

 of spine is white and from thence springs a broad oblique white 

 stripe pointing forwards and terminating at the spiracular region ; 

 a row of black spines just below the spiracles ; upon third, fourth, 

 and fifth segments an additional spine between the subdorsal and 

 spiracular row ; a short black blunt tubercle on second segment 

 upon each side of the face ; a short black spine above each leg and 

 claspers, which are shining black. The chrysalis, which is of an 

 amber brown colour, is slightly angulated, with a blunt subdorsal 

 black-tipped spine on each side of the abdominal segments, and 

 some small black spines on back of thorax ; a large and almost 

 triangular orange-yellow blotch upon back of anterior abdominal 

 segments ; wing sheaths dark reddish-brown, with the nervures 

 well-marked. 



These larvse differed in no way from larvae I have taken at the 

 Duke of York Islands and New Britain, and which produced the 

 blue variety Urvilliana, Guer., and the usual golden-green form, 

 and I feel quite convinced that Kirby is correct in referring the 

 fi.ve Australian varieties, and several others from New Guinea, 

 Woodlark Island, Batchian, &c., to Papilio Priamus, Linn., of 

 which there is little doubt that they are merely local varieties. 

 The Chrysalids are also indentical. Those I found were attached 

 to the midrib of a very large leaf of some forest tree, and some- 

 times at a considerable distance from the food of the larvse. 

 Before suspending itself the larvse takes care to securely fasten the 

 stem of the leaf at its base to the branch of the tree with strong 

 threads of silk. 



Papilio Polydorus, Linn. One of the most abundant species 

 met with. It flies in a light airy manner, generally quite straight 

 like Eurycus or Acrcea and appears to be a particularly easy 

 butterfly to catch, nevertheless it has a trick of dropping suddenly, 

 or twisting to one side, as one makes a stroke at it, and instead of 

 having it in your net, as you confidently expected, you see it 

 hurrying ofi" among the brushwood or careering aloft far out of 

 reach 



Papilio erithoneus. Cram. One or two seen.
