 scribed the habits of two European spe- 

 cies, the Apple-weevil, A. pomorum, 

 Fab., and the l*ear-weevil, ^'l. pyri., Kol- 

 hir, which deposit their e^gs in the 

 fruit buds of these trees. The Apple 

 curculio, A. quadrifjihbii.s, of Say, (Fif^. 

 (>5) and the Phnu-gouger, A. prunivida^ 

 of Walsh, are well known American spe- 

 cies. Both of these deposit their egfjs 

 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-famil}- belong to the genus AuthonomuSy Germ., of 

 which 15 species have been described.

Sub-faiuily ORCHESTIDES. 



From opxr^ffzTj-, a dancer or jumper. These resemble the Anthonomides 

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

 swollen, with a corresponding musculardeveloptnent which gives to them 

 the power of jumping. The prostemum 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 laivje. They are somewhat flattened, and i)ointed 

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

 ai)odal character of other curculioiiide larva'. l>ut the most anomalous 

 circumstance is that these larvi\; are leaf-miners, a habit of which there 

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

 ous analogy to the larva' of many of the 31icro-Lepidoi)tera ; and this 

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

 change to pupa», enclosing themselves in silken cocoons. Two X. A. 

 si)ecies have been described by ]Mr. Say belonging to the genus Orchestc.s, 

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



Sub-family ATTELABIDES. 



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

 [Fig. 67.] superior, large and pit-shaped. Antenna' 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 

 Curculionida*. They are divided into two groups : the 

 Attelabidos proper, with short, thick bodies, tibia' un- 

 guiculate at the end, and claws soldered together ; and 



* Othor examples are found in Hispa and Haltica.
