446 COLEOPTEUA. 



ratlier long and cylindrical, and occur in fungi, in the earth, or 

 under the bark of trees. Cobjdinm is slender, with finely 

 striate elytra, and the anterior tibiae have one spur enlarged 

 and hooked ; while the fli'st joint of the tarsi is elongated. 

 C elongotum is stated by European authors to attack the larvie 

 of Platypus, a genus allied to Scolytus. 



Ehtssodid.e Erichson. This group, by some authors united 

 with the preceding family, simulates the form of the Carabids. 

 The antennte are, however, composed of equal globular joints, 

 and the head is strongly constricted behind into a neck. They 

 are found under bark. In Rhyssodes the eyes are placed upon 

 the side, and in the other genus, CUnidium^ upon the upper 

 surface of the head. 



CucujiD.y. Latreille. The species of this family are very 

 much flattened long insects, with flat, strongly emarginated 

 elytra, and the abdomen has five full segments, equal in length. 

 They are found under bark. The larvte are quite transparent, 

 with the terminal joint ending in two horny curved hooks. 

 The antennte are fonr-jointed, the limbs provided with a single 

 claw, and there are five ocelli on each side of the head. In Syl- 

 vaniis^ which is of small size, the nine to eleven-jointed an- 

 tennae do not have the first joint elongated as usual, while the 

 terminal ones are enlarged. Sylvanns Simnainensis Linn, is 

 one-ninth of an inch long, of a rusty brown color, and covered 

 with short j^ellowish hairs. The larva is a flattened yellowish 

 white grub, with the terminal joint somcAvhat conical. It breeds 

 in bran, rice and wheat. Cvcnjus is a bright scarlet flattened 

 insect, with punctured elytra, and three faintly marked smooth 

 lines. The larvae differ from those of Sylvanus by having two 

 horny tubercles at the end of the abdomen ; they are often 

 found in granaries. 



Cryptophagid.e Kirby. This family differs from the pre- 

 ceding group in the greater length of the first abdominal ring, 

 the thickened body, and in the thorax being as wide as the 

 elytra. AntJicropJiagiis is readily known by its resemblance to 

 Epuraea among the Nitidnlidce , as its head and body is flat,
