ATTEMPTED DIVISION OF BRITISH INSECTS. 423 



Natural Order. — Cucujites, Flat-hodied-heeiles. 



Larva with six very short articulate legs ; found in decayed timber. 

 Pupa changes in the same situation. Imago, with filiform an- 

 tennae generally not longer than the prothorax ; mandibles acute, 

 porrected, and elongate, especially in the males ; the maxillae 

 obtuse ; galea pilose ; head somewhat triangular, elongated pos- 

 teriorly into a kind of neck ; prothorax nearly square, very flat ; 

 body very flat ; tarsi four-jointed. Inhabits timber. Cucujus, 

 Trogossita ? {Parandra, Passandra.) 



Natural Order. — Bostricites. 



Larva a white maggot, completely without legs ; inhabits and feeds 

 on the bark or wood of trees, causing their death with unerring 

 certainty. Pupa changes in the same situations. Imago, with 

 clavated antennae ; mandibles generally bidentate ; maxillae, with 

 their galea obtuse ; the prothorax very convex, and usually as 

 large as the remainder of the body ; tarsi four-jointed ; form 

 cylindrical. Inhabit circular holes, which it bores in the bark 

 and wood of trees, either to escape, after changing, from the pupa, 

 or to deposit their eggs. Cis, Bostrichus, Tomicus, Platypus, 

 Hylesinus, Scolytus, Hylurgus. 



Natural Order. — Curculionites, Weevils. 



Larva without legs, and having occasionally in their place small 

 mamillary 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 antennae generally twelve-jointed, incrassated externally, 

 the basal joint generally very long, the others bending forwards 

 at a right angle, forming an elbow ; these antennae 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 ; feed on vegetables. Curculio. 



Natural Order. — Anthribites. 



Larva as in preceding, feeding on wood. Pupa changes in the 

 channels made by the larva. Imago, with antennae generally 

 twelve-jointed, the basal joint not particularly elongate, therefore 

 not elbowed, moniliform, incrassated externally, not situated on a
