Section II. HETEROMERA. 



(Beetles which have five joints to the first and second pairs of 



tarsi, and four to the hind pair.) 



Family XXXI I. TENEBRIONIDJE. 



These are, for the most part, black in colour. The antennce 

 are inserted under the expanded lateral border of the head, 

 which covers the first joint to a greater or less extent. The 

 abdomen is globular or oval. 



Genus Blaps, Fabr. 

 These are wingless beetles, with short antennae, the last 

 joints of which are almost spherical. The elytra are rather 

 broader than the pronotum, and nearly twice as long as broad. 

 They live in dark places. 



* B. mortisaga, Fabr., the Cellar Beetle (Plate XII., Fig. 8). 

 This species has a yellow tuft of hair in the middle of the 

 hind border of the first abdominal segment in the male. Both 

 the beetle and its hard, elongated larva are found under rotten 

 boards, and in cellars. It is very rare in Britain, though one 

 or two closely allied species are common. 



Genus Opatrum, Fabr. 

 Body rather flat, broad, and oval. The front coxae are only 

 slightly further from one another than the middle pair. The 

 eyes are at the lateral margins of the head, and divided into 

 two. They are found under stones in sandy places. 



* 0. sabulosiLin, Linn. (Plate XII., Fig. 9). This insect is 

 black, ashy-grey above, and slightly convex. The front tibiae
