458 Miss M. E. Fountaine's Notes on Papilio demolion. 



I much regret not to have been able to draw this larva 

 in its early stages, but on board ship this was impossible, 

 especially as when the boat was motionless at the various 

 ports, we were always much too busy on shore, searching 

 for orange and lemon trees, or indeed any kind of Citrus, 

 on which to feed, not only the P. demolion, but some fifty 

 or sixty large larvae of Papilio memnon,* besides eight 

 young larvae of some other Papilio, brought in on branches 

 of lime, at Macassar (Celebes). The first demolion to pupate 

 was on the very day we arrived at Brisbane, having there- 

 fore spent the whole of its larval existence at sea ; and 

 the others soon followed its example, but luckily not before 

 I had had time to make a drawing of one of them. (See 

 Plate LXVI, fig. 2.) 



The pupa of this remarkable butterfly is also very 

 distinct (see Plate LXVI, fig. 3), especially by the long 

 projection below the thorax. As usual, those that pupated 

 on the food-plant were green, and those which selected 

 the side of the cage were brown. 



* I was told by my friend Mrs. Walsh of Soekaboemi that P. 

 memnon in Java has no less than six different forms in the $, and 

 that was, of course, why we were breeding so many of them. Mrs. 

 Walsh also told me that she was not acquainted with the ova of 

 P. demolion, but had often found the larvae on lime trees, always, 

 however singly, which can no doubt be accounted for by the other 

 members of that group having fallen a prey to their innumerable 

 enemies. — M. E. F.
