 ground; they leap to distances of twenty times their diameter, making a 

 noise like the patter of rain. Larvse of Carpocapsa .taliita7-is (larva, pupa 

 and imago here described) occur, in Peru, Mexico and California, in cap- 

 sules of an Euphorbia? (hei-e described), and by their motions (here de-
