Swine and domestic fowls are fond of the grubs, andwill destroy them when allowed to have access to the infested field. From experiments made by Mr. W. B. Alwood, it is probable thatkerosene emulsion may be used successfully for the destruction ofthis insect wliile in the ground, but it is necessary to thoroughlydrench the ground, for the purpose of reaching the grubs. This planis well worth a trial on lawns, but it is doubtful if it would pay infields. THE PLUM CURCULIO. Conotrachelus nenuphar (Herbst.). The plum curculio belongs to the group of snout-beetles or weevils,and is very injurious to cherry, quince, peach, and apple trees, aswell as plum trees. The perfect beetle, fig. 8, c, is about one-fifthof an inch long, grayish-brown or black in color, while on the wing 17 covers is a black shining hump behind which is a dull yellow bandand a few white markings. The thorax and wing covers are rough-ened and uneven, and the snout is about as long as the thorax. There is only one brood in a year. The beetles pass the winter inthe perfect state, hiding under the loose bark of trees, rubbish, andin other convenient places ; and are first seen in May or June whenthe fruit is fairly set. The female at once lays her eggs, from fiftyto a hundred in number, in the young fruit, making a small hole withher snout, and depositing only one egg in a single plum. She thencuts a crescent shaped slit in front of the hole, fig. 8, d, thus under-mining the egg and preventing the growing fruit
