their slender beaks. On hatching from the egg the young grub at once 

 begins to feed on the contents of the kernel, completes its growth and 

 turns to a beetle inside the same grain, which does not show any sign of 

 injury until the beetle emerges, when it is found that the greater part of 

 the inside has been consumed. In wheat and other small cereals a single 

 larva inhabits a grain, but a kernel of corn furnishes food for several 

 individuals. The mature beetles also feed upon the grain, and live for a 

 long time, so that in warm places where grain is kept in store for a length 

 of time, the injury may be considerable. In the course of a single year 

 it has been estimated that one pair of these weevils will produce 6,000 

 descendants, so it can be readily seen that they are capable in a short 

 time of doing much damage. 



The Rice Weevil (Calandra oryzce, L.). 



This insect differs somewhat in size and general appearance from the 

 Granary Weevil. Unlike that species, it possesses fully-developed wings, 

 has two yellowish blotches on each wing-case, is slightly smaller and of a 

 pale brown colour. The life-history of this insect is similar to that of the 

 preceding species, except that in very warm climates the beetles are often 

 found in fields away from any granary, and in the extreme South and in 

 the Tropics the females lay their eggs in standing grain. The Rice 

 Weevil is often found injuring stored grain in company with the Granary 

 Weevil. 



The Angoumois Grain Moth (SitoU-oga cerealella, 01. j. 



In Canada the Grain Moth has never developed sufificiently to be 

 considered an important enemy of stored grain. In Southern climates, 

 however, where it is very abundant, this insect is a bad pest. The moths 

 fly from the granaries to the field and lay their eggs upon standing grain. 

 The eggs, or young caterpillars are thus carried with the threshed grain 

 into the granary, where they develop and, cause great loss. The moths, 

 however, have not so far been recorded as laying their eggs upon standing 

 grain in Canada, and where damage has occurred, it has been to infested 

 grain which had been imported. The eggs are deposited in groups of 

 from 15 to 25, generally upon the under side of the grain or in the crease 

 of the kernel. They are while at. first, turning pink before hatching. The 

 young caterpillar is a minute creature, slender, and covered with long 

 hair. When n\ature it is 2-5 of an inch in length, and of a dirty white 

 colour. As a rule only one larva enters each grain, but when corn is 

 attacked, two or three larvae may be found in a single kernel. After
