They are often found in the seeds of pease and beans, and, in company with the Bruchus granarius, and the larvae of a species of saw-fly, work sad destruction in the stock. The Bruchus granarius is thus described in the " Cottage Gardener," vol. iii. p. 13:—" These holes in the peas and beans are made by this beetle, which is produced from a grub or cater- pillar, which has eaten away the vital parts of the seed; and when it has passed through the chrysalis state, and given birth to this beetle, the latter makes the hole in order to escape into the open air, there to perpetrate more mis- chief upon the growing crops. The body of the beetle is a dull brown, but the elytra?, or wing- covers, are black, dotted with white, but scarcely perceptibly so, unless magnified, as in our draw- ing. Naturally it is the size of the smaller figure, and is scarcely two lines long. The antennas are eleven—jointed, black, and thinnest near the head, where they are also tinged with red. The head droops, the eyes are prominent, the fore-legs are rusty coloured. The female pierces through the pod of the pea or bean whilst very young, and often deposits an egg in each ; This insect may be destroyed by the American mode of dipping the seed in boiling water, as noticed above. The pupse of the fly Phytomyza nigricornis, the black-horned leaf-miner, fig. 11, feed on the Fig. BLACK-HORNED LEAF-MINER. parenchyma of the leaf, causing minute brown spots in it. The only mode of riddance ap- pears to us to be picking off the infected leaves and burning them, to prevent the further breed- ing of the insect. The cross lines show the natural size of the insect. The next serious enemies to the pea are mice and rats. As preventives, rubbing the pease with powdered resin, placing over them in the drills chopped
