(Beetles which have all the tarsi four-jointed.) 



Family XLI. CURCULIONIDiE (Weevils). 

 Head drawn out into a proboscis. Antennae nearly always 

 elbowed and thickened towards the extremity. The Weevils 

 form a very large family of beetles, all of which live upon 

 vegetable food, some being consequently very destructive. 

 The larvae are footless maggots, which also live upon the leaves, 

 stalks, and roots of plants. 



Genus Otiorhynchus, Germar. 

 Very convex beetles, usually of a black colour. Antennce 

 long, the flagellum extending beyond the eyes. Elytra of 

 variable length, oval, and rounded at the shoulders. The 

 species are numerous, and very difficult to distinguish. 



* 0. unicolor^ Herbst (Plate XIII., Fig. 1). This is a shining 

 black beetle. The pronotum is nearly as long as broad, and 

 the elytra are indistinctly punctured. It is found on wooded 

 slopes. 



* 0. ligustici, Linn. (Plate XIII., Fig. 2). Black, more or 

 less thickly covered with grey scales. The proboscis has a 

 raised median stria. It lives on the young shoots of the peach 

 trees and on vines. It is very rare in England. 



Genus Phyllobius, Schonherr. 

 These are winged beetles, with a very short, stout proboscis,. 

 and rather long and slender antennae, the first two joints of
