Itis a quarter of an inch nennpliar Herbst,the Plum-Weevil (Fig. 466; a, larva; 6, pupa; c, beetle; d,plum stung by the weevil) is a short, stout, thick weevil,iind the snout is curved, rather longer than the thorax,and bent on the chest when at rest. It is dark brown,spotted with white, ochre-yellow and black, and the surface isrough, from which the beetle, as Harris sa3s, looks like a. CURCULIONID^. 489 •dried bud when shaken from the trees. When the fruit is set,the beetles sting the plums, and sometimes apples and peaches,with their snouts, making a curved incision, in which a singleegg is deposited. Mr. F. C. Hill shows tliut the curculiomakes the crescent-shaped cut after the egg is pushed in soas to undermine the egg, and leave it in a kind of flap formedby the little piece of the flesh of the fruit which she has undermined. Can her object be to Avilt the piece around the eggand prevent the growing fruit from crushing it? (PracticalEntomologist, ii, p. 115.) The grub hatched therefrom is alittle footless, fleshy white grub, with a distinct round lightbrown head. The irritation set up by these larvae causesthe fruit to drop before it is of full size, with the larva stillwithin. Now full-fed, itburrows directly into theground and there trans-forms during the last ofthe summer. In threeweeks it becomes a beetleIt also attacks many othergarden fruits, such as the
