usually in a heap in the lower end of the mine ; in 

 Khamnus Cathartica and Clematis vitalba it appears to 

 be fluid, not granular." 



In more unexpected places we <3ome upon the larvae of 

 Moths. Those of the family Galleridce, in the group 

 Pyralidinae, inhabit in large numbers the hives of Bees, 

 where they, protecting themselves from attack by the 

 construction of silken galleries (hardened, it is said, with 

 wax), feed upon the waxen combs, occasioning such 

 mischief as sometimes to destroy the hive. 



Another family, in the same group, are aquatic, some 

 living under water in cases filled with air, while others, 

 furnished with fish-like breathing apparatus, breathe in 

 the water itself. 



The variety of food thus shown to be used by the 

 larvae of Moths may probably be new to the reader, who 

 it is likely has thought of Caterpillars as exclusively 

 vegetarian in their habits, excepting the little Clothes- 

 Moth grubs, with their taste for hair of all sorts, whether 

 in the form of woollen stuffs, fur, or horsehair stuffings. 

 But there are not only species which feed on dead animal 

 matter of very various kinds, as the hair aforesaid, 

 leather, grease, and butter ; but there are some which, 

 whatever their natural and usual food may be, will feed 

 also on other living insects. This is the case with the 

 large evil-smelling Caterpillar of the Goat Moth, and the 

 " Satellite," and it is on this account carefully watched 

 by the collector, as it will eat even its own species. The 

 larvae of the Puss Moth eat their >east skins, whilst some 

 larvae eat their own egg-shells on emerging from them. 

 These may be dainty, but can hardly be very nourishing 

 food. 



With regard to variation in food, it may be mentioned
