a? that have hatched from eggswhich have been dropped loosely, a habit adult females seem to haveafter they have laid a number of eggs in the same day. The larva? that hatch from eggs deposited in cavities burrow down-ward toward the center of the stalk, enlarging their tunnels as theyproceed. When the stalk is young and tender they seem to consumepractically everything in their tunnels as they come to it, but in theolder stalks the larva? tear off large pieces, which are reduced to frassand left in the tunnel behind them. As the larva grows older it seemsto tear off proportionally more and more of the stalk than it candevour, so that usually by the time it is ready to pupate the larvalburrow is pretty well filled with fragments of stalk in the immediatevicinity of the larva, and it is from these fragments that the pupalcell is constructed. The larva is capable of comparatively rapid movements when dis-turbed, but normally it does not seem to move very far from the end 70 The Bulletin
