[j. c] [f. v. t.]Ceutorrhynchus assimilis (Turnip-seed Weevil) inhabits the flowers of the turnipand cabbage, and bores a hole in the incipientpods to lay its eggs in them. The maggots arefound doing much mischief by feeding on theseeds. When they are full grown, they gnawa hole in the pod, and, falling to the ground,bury themselves to construct cells in the earth,in which they change to ochreous pupae withblack eyes, and from these weevils issue. Theyare of a slate-black, clothed all over with veryshort white hairs; the proboscis is long andcurved, the antennse are slender and elbowed ;there is a, tubercle on each side of the trunk,and a grey channel down the back; a tooth.

C. contractus (the Charlock Weevil) is a muchsmaller species, which is bred from the rootknobs of the charlock (Sinapis arvensis), andpowerfully assists in injuring the young turnipcrops by puncturing the leaves with its ros-trum. It is from f to 1 line in length, blackwith a coppery tinge; the wing cases are oftengreen or blue, with punctured furrows, andlines of minute hairs between them.
