eyes are very prominent ; the trunk is obversely funnel-shaped ; 

 and the tibiae, at the apex, are armed with a single crooked 

 spine : on the contrary, in At. Betula, curculionoides, and the 

 curculios of Mr. Marsham's first family, the antenna? have a 

 subperfoliate clava with very distinct joints ; the head has no 

 separate neck, nor is it elongate or obconical ; the trunk, in 

 most,issubglobose; and the apex of the tibiae without spines: but 

 in At. curculionoides, which seems intermediate between At. 

 Coryli and Betulce, Populi, &c. the trunk inclines rather to a 

 square form ; and the apex of the tibiae is armed with two spines. 

 But these insects are all more nearly related to each other than 

 they are to the tribe of which I am now speaking, although Fa- 

 bricius and most others have confounded them together. Mr. 

 Marsham and Herbst seem to be the only entomologists whose 

 penetration has detected the difference between them*. I shall

* The ingenious author of Entomologie Helvetique, whose work I had not had an. 

 opportunity of consulting when this passage was written, ha3 separated the species that 

 belong to Mr. Marsham's first and second families of Curculio from Attelalus, Fabr. 

 and given them, after Geoffroy, as a distinct genus (Rhinomacer) which he has divided 

 into three families. The first contains the greater proportion of the species of Apion; 

 the second, those that have a rostrum attenuate at the apex, like Ap. Craccce ; and the 

 third, the species that constitute Mr. Marsham's first family ; e. g. Cure. Populi, Bac- 

 chus, &c. 



M. Latreille also, in the work before quoted, (of which I had then only seen those 

 sheets which relate to my Monograph upon Apis, Linn.) divides Attelalus, Fabr. into 

 two families, each of which he further subdivides into two sections. Thus,
