slighter for its length than that of P. polytes. The larva is very- 

 much parasitised and does not use the osmeterium much. The 

 butterfly has a very quick and strong flight and is always 

 hurrying along whenever met with like, P. machaon at home, 

 though it is a faster flier than this latter. It does not rise very 

 much above the ground and is fond of flowers and the sun ; it is 

 commoner in the Plains than in the jungles and hills and may be 

 seen on the wing throughout the year. Its range is Kashmir to 

 Ceylon ; eastwards to Burma up to a moderate elevation in the 

 hills ; westwards to Persia ; it is found also in China and For- 

 mosa. The food-plants are belonging to the family Pvutacese 

 and it has been bred on Butco graveolens, L. ; Glycosmis pentaphylla, 

 Correa ; Murraya koenigii, Sprengler ; Citrus decumana, L. ; Aegle 

 Marmelos, Correa; all rutaceous ; on Chloroxylon swietenia DC, 

 one of the Meliacece. The last food-plant is very exceptional 

 and the larvas did not look very healthy that were found on it. 

 C. swietenia looks at first sight rather like a leguminous tree and 

 this most probably led to a statement made in " Notes on the 

 Larvee and Pupse of some of the Bombay Butterflies " by E.H.A. 

 that it had been found on " leguminous plant with aromatic 

 leaves." In that paper, published in this Journal in the year 

 1896, the butterfly is called P. erithonius. The figure on the 

 coloured plate is good.
