peas. 



The Genus Rhynchcenus has the snout 

 long and slender, and the antennae near 

 the middle of it. 



The White-Pine Weevil, R. strobi, 

 Peck, bores the pine when in the lar- 

 val state. 



The Long-snouted Nut-Weevil, R. nasicus, Say, attacks 

 nuts while it is in the grub state. 



The Genus Curculio contains the Plum- 

 Weevil, C. nenuphar, Herbst, about one 

 fifth of an inch long exclusive of the 

 snout, rough, dark-colored, and, when 

 shaken from the tree, appearing like a 

 dried bud. This beetle makes a crescent- 

 shaped incision with its snout in the 

 surface of the plum, and then lays an 

 egg in the wound ; and it goes from one 

 plum to another till the stock of eggs 



is exhausted, so that where the beetles are 

 plentiful not a plum escapes stinging. From 

 the egg there hatches a whitish grub, desti^ 

 tute of feet, and with a rounded light brown 

 head, which immediately burrows into the 

 fruit, and ultimately penetrates to the stone. 



^he GenUS Cdfattdn* Comprises beetles 



w hi c h attack stored wheat, corn, and rice. 

 They lay their eggs upon the grain, and the larvae, as 

 soon as hatched, burrow into the kernel, destroying every- 

 thing except the hull, which is left entire, so that the 

 inj ury done is not perceived till the lightness of the ker- 

 nel reveals it. 



The Grain Weevil, C. granarius, Linn., of Europe, is 

 about one eighth of an inch long, and pitchy-red. A 



Long-snouted Nut- 

 Weevil, R. nasicus, 

 Say.
