In warm countries, such as those of southern Europe, there are many broods during the year, and the loss caused is corres- pondingly great. The beetles penetrate some distance into the heap of grain ; the female lays her eggs singly in the grains, and in a few months there remains nothing but a heap of empty husks, tenanted by grubs and beetles. At an entomological meeting in Eng- land, April 1870, it was stated that 74 tons of Spanish wheat when sifted yielded over half a ton of weevils, and 145 tons of American grain gave one and three-quarter tons. Fortunately these beetles do not thrive without heat, and cannot carry on their depreda- tions in the cold of our winter, hence grain can be stored here for many months without loss. The Apionidce are a group of small pear-shaped weevils the minute larvae of which infest different seeds. Besides these we might mention as destructive the quince curculio (figure 40), Cono- trachelus crataegi, which is injurious to quinces ; the imbricated snout beetle, Upiccerus.
