The following interesting notes upon this subject are taken from a paper recently received from Mr. L. de Nicéville, of Calcutta:

“The larvæ of many kinds of butterflies will, when they cannot get vegetable food, eat each other or soft, newly-formed pupæ. Mr. Bell has found that the greatest cannibals in this respect are the larvæ of certain Lycænidæ, and the worst among these, again, are the larvæ of Zesius chrysomallus, Hübn., for these will at times, even when plentifully supplied with their proper vegetable food, eat any larvæ which may be in a fit state to be eaten; i.e., which are either on the point of casting their skins, have just cast them, or are just going to pupate. The Lycænid larvæ, which are most addicted, after that of Z. chrysomallus, are those of the Amblypodia and Tajuria groups, those of Arrhopala and Rapala being nearly as bad.
