SNOUT-BEETLES OR WEEVILS.

[rig. C6.] being- iujnrious to fruits. Kollar has de- 



scribed the habits of two European spe- 

 cies, the Apple-weevil, A. pomorum, 

 Fab., and the Pear-weevil, A. 2>y>'h Kol- 

 lar, which deposit their eggs in the 

 fruit buds of these trees. The Apple 

 curculio, A. quadrigibhus, of Say, (Fig. 

 Go) and the Plum-gouger, A. prunicida, 

 of Walsh, are well known American spe- 

 cies. Both of these deposit their eggs 

 in the fruit. The larvae of these insects do not go into the ground to 

 pupate, like the common Plum-curculio and many others, but go through 

 all their stages in the buds or the fruit which they infest. All the N. A. 

 insects of this sub-family belong to the genus Anthonomus, Germ., of 

 which 15 species have been described. 



Anthonomus, 4-gibbu8, Say: — a, pupa; b, 

 larva, enlarged — after Riley. 



Sub-family OECHESTIDES. 



From op^T^ffTTj^, a dancer or jumper. These resemble the Anthonomides 

 iu most of their characters, but differ in having the hind thighs much 

 swollen, with a corresponding muscular development which gives to them 

 the power of jumping. The presternum is very short, permitting the 

 rostrum to be bent beneath in repose. Eyes large, oval, and nearly 

 meeting above. This little group is very remarkable for the structure 

 and habits of the larvas. They are somewhat flattened, and pointed 

 behind, and furnished with six feet, a remarkable departure from the 

 apodal character of other curculionide larva?. But the most anomalous 

 circumstance is that these larvse are leaf-miners, a habit of which there 

 are but few examples* in the order of Ooleoptera, and exhibiting a curi- 

 ous analogy to the larva? of many of the Micro-Lepidoptera ; and this 

 analogy is carried out by the larvae when fully grown and about to 

 change to pupoe, enclosing themselves in silken cocoons. Two IS". A. 

 si)ecies have been described by Mr. Say belonging to the genus Orehestes, 

 Illiger. They are only about a tenth of an inch in length. 



Sub-family ATTELABIDES. 



Eostrum more or less robust and enlarged at the extremity ; scrobes 

 [Fig. 67.] superior, large and pit-shaped. Antennfe straight, or not 

 elbowed, the first joint being but little longer than the 

 following ones. This character readily distinguishes this 

 and the following sub family from the great majority of 

 Curculionidse. They are divided into two groups : the 

 Attelabides proper, with short, thick bodies, tibiae un- 



ATTELABus. guicuUite at the end, and claws soldered together ; and 



* other examples are fouud in Hispa aud Ilaltica.
