 of the last. The usual food is Zantlioxylum Rlietsa^ D, C. Prod.

We may discard the alias, P. Uomedon, Moore, under which we 

 described and figured the transformations of'this species in our former 

 paper (Journal Bombay Natural History Society, Vol. V,p, oGT^n. 75, 

 1890). It is not a rare butterfly in Canara, but more local than most, 

 owing perhaps to its feeding exclusively (so far as we i^know) ou 

 Acronychia laurifolia^ Bl. Bijd., a tree which is almost confined to the 

 tops of wooded hills. We have met with the butterfly chiefly from 

 August to October.

This magnificent butterfly is one of the two species of Papilio 

 which have as yet successfully defied us to find their larvas, but we 

 have no hesitation in putting it into this group. It can scarcely 

 belong to any other. It is found in many parts of the district as far 

 north as Castle Rock during the rains and also in March and April, 

 but it is very local. Like most of the. group it has a regular beat, 

 round and round vdiich it goes during the hottest hours of the day, 

 with little change ; so that, by taking your stand where one has passep, 

 you may make pretty sure of meeting it again every half hour or so, 

 that is, if you go on missing it. If you catch it that ends the fun. Of 

 ■course you get only males in that way. We do not know how females 

 ^XQ to be got. Two specimens have fallen into our hands by accident.

This species, which is even more splendid than the last, appears to 

 be spread over the whole district, affecting cultivated tracts as well as 

 forest, and is by no means rare in some parts ; but it is one of the most 

 difficult of all butterflies to come by. It usually flies vez'y high and 

 fast, and seldom alights or hovers over flowers. Yv'hen caught, if not 

 already broken, it often contrives to break off" a goodly bit of one 

 wing in the net. We had long been sure that it laid its eggs on 

 ■Zaniho.vi/lum rhetsa, D. C. Prod., already mentioned as the favourite 

 food of P. daksha, Moore, and at last, on 24th September^ 1892, we 

 got one larva. This died two days after of mere " cussedness," but we 

 liad got on the scent now, and hunted every accessible leaf of every 

 >kaown tree within some miles of Karwar. To realise the difficulues
