 MIPEPLUS. 



Gen. CUCUJTJS, Fab. Lat. 



Antennae moniliform, shorter than the body ; labrum advanced 

 between the mandibles ; labium bifid ; body much flattened ; 

 tarsi short. 



C. depressus, Lat. Upper part of the body red ; the under part, 

 antennae, mouth, and feet black ; thorax furrowed and crenated 

 on the margin. Inhabits Sweden and Germany, under the bark 

 of trees Lai. Gen. iii. 25.

 elytra striated. Found near Paris. Nouv. Diet. viii. 535. 



FAMILY IV. LONGICORNES. 



First three joints of the tarsi furnished with pencils below, and 

 the two intermediate broad, triangular or cordiform, the third 

 deeply bilobate ; labium triangular or cordiform, notched or 

 bifid ; antennae filiform or setaceous, as long as or longer 

 than the body, sometimes inserted in a notch of the eyes, 

 sometimes outside ; feet long and slender, with long tarsi ; 

 body elongated. 



The Coleoptera of this family have generally a narrow elongated body, depres- 

 sed above ; the head projecting, sloping, or vertical ; the antenna slender, often long 

 and setaceous, composed of eleven joints, and sometimes of a greater number. The 

 eyes are crescent-shaped or globular : four short filiform or clavate palpi ; the jaws 

 proper for sucking the juice of flowers or the liquors which are exuded from trees. 

 The thorax is of various forms, square, cylindrical or orbicular ; the elytra elongated, 

 terminated in a point, or spinous at the extremity, and in many covering the wings ; 

 abdomen terminated in a scaly point, or a kind of ovipositor in the females. When 

 seized these insects emit a plaintive broken sound. Many of them are nocturnal. 

 The smaller species are found on flowers, and the larger on the trunks of trees or in 

 old wood. The larvas, of a white colour, are found in wood or the bark of trees, 

 are deprived of feet, or have very small ones. Their body tapers gradually from the 

 head, and their mandibles are so strong, that they have been known to furrow even a 

 plate of lead. 



TRIBE I. PRIONII. 



Antennae inserted in a notch of the eyes ; head sunk to the 

 eyes in the thorax ; last joint of the palpi conical or cylindri- 

 cal and truncated at its extremity ; wings folded under the 

 elytra ; labrum none or very small; body generally depressed, 

 with the lateral borders of the thorax edged, dentated, or spi- 

 nous ; antennae of the males pectinated or serrated. 

 Gen. SPONDYLIS, PRIONUS, THYRSUS, ANACOLUS. 



Gen. PRIONUS, Geoff. Lat. Fab. Cerambyoc, Lin. 

 Body depressed, elongated ; head flattened, directed forwards ; 

 mandibles strong, dentated interiorly ; palpi terminated by a 

 larger joint, conical or like a reversed triangle ; antennae al- 

 ways longer than the thorax, serrated or pectinated in some, 

 simple or spinous in others ; thorax edged, dentated, or un- 

 equal,
