446 COLEOPTERA. 



rather long and c^'linclrical, and occur in fungi, in the earth, or 

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

 striate elj'tra, and the anterior tibiae have one spur enlarged 

 and hooked ; "while the first joint of the tarsi is elongated. 

 C. elongatum is stated by European authors to attack the larvae 

 of Platypus, a genus allied to Scolytus. 



RnYSSODiD.E Erichson. This group, by some authors united 

 with the preceding faniil}^, simulates the form of the Caral)ids. 

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

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

 are found under bark. In Rliyssodes the ej^es are placed upon 

 the side, and in the other genus, Clinidium, upon the upper 

 surface of the head. 



CucujiD^ 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. 

 The}^ are found under bark. The larvae are quite trausparent, 

 with the terminal joint ending in two hornj^ curved hooks. 

 The antennae are four-jointed, the limbs provided with a single 

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

 vanics, 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. Sylvanus Surinciviensis Linn, is 

 one-fourth of a line 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 somewhat conical. It breeds 

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

 insect, with punctured elytra, and three faintly marked smooth 

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

 horny tubercles at the end of the abdomen ; thej- are often 

 found in granaries. 



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

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

 the thickened bod}^, and in the thorax being as wide as the 

 elytra. Anther opliag us is readily known hj its resemblance to 

 Epuraea among the N it i dull dee , as its head and boch' is flat,
