262 CLASSIFICATION OF INSECTS. 



legs, and having occasionally in their place small mammillary 

 processes ; inhabits and feeds on the flowers, fruits, seeds, 

 leaves, stalks, bark, wood, pith, and roots of vegetables. 

 Pupa changes in the same situations, sometimes naked, 

 sometimes in a hard compact case, sometimes in a silken 

 cocoon. Imago with antenna generally twelve -jointed, 

 incrassated externally, the basal joint generally very long, 

 the others bending forwards at a right angle, forming an 

 elbow ; these antenna are placed on a long rostrum, which 

 proceeds from between the eyes, and has the mouth at its 

 extremity ; mandibles generally obtuse ; blade and galea 

 of the maxillae united and indistinct; tarsi four-jointed. 

 Mostly diurnal ; feeds on vegetables. Curculio : Balaninus 

 Nucum, a very long-nosed weevil, produced from the well- 

 known grub which infests nuts and filberts, is represented 

 on the opposite page. 



Short-nosed weevils or Anthribites. Larva in form like 

 the preceding ; feeds on wood. Pupa changes in the chan- 

 nels made by the larva. Imago with antenna generally 

 twelve-jointed, the basal joint not particularly elongate, 

 therefore not elbowed, moniliform, incrassated externally, 

 not situated on a distinct rostrum, much elongated in the 

 males ; mandibles and maxilla nearly as in the preceding 

 order ; tarsi four-jointed. Inhabits the bark and wood of 

 trees. Br achy tarsus, Platyrhinus, Anthribus. 



False-weevils or Salpingites. Larva and pupa as in the 

 preceding orders ; the former feeds on the wood and bark 

 of trees. Imago with antenna shorter, moniliform, some- 

 what incrassated externally, and situated on a rostrum; 

 mandibles and maxilla obtuse ; fore and middle tarsi five- 

 jointed ; hind tarsi four-jointed. Found in the same situ- 

 ations as the larva, and also among the leaves of trees. 

 Salpingus, Sphariestes.
