STATE HORTICULTURAL SOCIETY. 201 



It is a dark brown color, but the thorax is sparsely and the wing-cases 

 densely covered, especially toward the tips, with yellow hair, thereby giv- 

 ing it a rusty yellow appearance. 



This is supposed to be the weevil that attacks the hazlenut, in which 

 it spends its larval state. 



Spec. Char. Inia<^o. — Snout very long, nearly equal to the length of the body, and 

 very slender and cylindrical, almost as fine as a bristle, strongly curved, somewhat de- 

 flexed. Thorax cone-shaped, much narrowed in front, and slightly dilated in the mid- 

 dle; considerably narrower behind than the elytra. Elytra broadest in front and taper- 

 ing posteriorly; the shoulders very prominent; stri;x- numerous and very slender, punc- 

 tured very minutely. Posterior tibia; suddenly enlarged at the tip. Snout dark reddish 

 brown, naked ; thorax and elytra covered thickly with short depressed rusty yellowish 

 hairs, palest near the posterior extremity. The length, exclusive of the snout, is about 

 one-third of an inch ; width across the base of the elytra about half the length. 



Anthonomus quadrigibbus , Say. Apple-curculio. 



This curculio -is readily distinguished by the following characters : 

 It is usually of a uniform rtisty brown, but occasionally the thorax and 

 front portion of the wing-cases are ash, gray ; four tubercles on the wing- 

 cases, two on each, situated on the posterior half, on a line nearly parallel 

 with the middle suture ; the snout varies in length from half to the length 

 of the body, according to the sex. Length, exclusive of the snout^ from 

 a little over one-twentieth to two-twentieths of an inch. From Prof. 

 Riley, who has studied tlie preparatory states of this species, we learn 

 the following facts: The female punctures the fruit with her snout, 

 enlarging the incision at the bottom, and having deposited an egg thrusts 

 it to the bottom, I presume as does the plum-curculio, with her snout. 

 This &gg is about four-twentieths of an inch long, the diameter being about 

 one-third the length, and of a yellowish color. As soon as the larva is 

 hatched it usually goes to the heart of the fruit and feeds around the core, 

 producing a rust-red excrement. When fully grown it is about two-fifths 

 of an inch in length, soft, and white, curved, and transversely wrinkled, 

 longest in the middle ; head almost perpendicular, yellowish brown with 

 darker mandibles; it has no bristles, like the larva of the plum-curculio, 

 except a few weak ones on the first joint beneath ; a blueish line is some- 

 times visible along the back ; is footless. 



Unlike the plum-curculio, this species undergoes its transformations 

 in the fruit it inhabits, which does not prematurely fall, as is usual with 

 that infested by the plum-curculio, or the codling-moth worm. 



The wild crab appears to be its favorite fruit, but it also attacks the 

 cultivated apple occasionally, doing considerable injury ; the pear also 

 appears to be subject to its attacks. 



It appears to be more common in the southern part of the State, 

 than in the central or northern portions. 



It winters in the perfect or beetle state, and makes its appearance 

 and commences work about the latter part of May, and from that time 

 probably until July. 



So far no sufficient experiments appear to have been made in refer- 

 ence to remedies suggested, to enable us to decide in regard to their
