200 INSECTS AT HOME. 



from timber which was being used for building purposes. This 

 Beetle has also been discovered embedded in a seam of coal at 

 Coatbridge, at a depth of nearly 900 feet from the level of the 

 ground. It is evident that the insect must have emerged 

 from some of the timber which is so largely employed in coal- 

 mines. 



A RATHER remarkable Beetle is shown on Woodcut XXI. 

 Fig. 4. Its name is Pogonocerus pilosus, both of which titles 

 refer to the structure of the antennae. In this genus the body 

 is short and rather convex, the disc of the thorax is covered 

 with tubercles, the tips of the elytra are developed into spines, 

 and the antennae are covered beneath with a clothing of hair. 

 The generic title Pogonocerus (mostly, but wrongly, spelt 

 Pogonocherus) is formed from two Greek words, the one signi- 

 fying a beard and the other a horn ; so that the whole word 

 may be translated as ' bearded-horn.' The specific name, 

 pilosus, is Latin, and signifies 'hairy.' There are three 

 known English species, one, Pogonocerus fascicularis, being 

 very rare, and the other two moderately plentiful. The present 

 species has the tubercles of the thorax pointed, and there are 

 two sharp spines on either side of the thorax. The general 

 hue of the insect is reddish-brown, the elytra having a broad 

 grey band at the base, and some black spots near the suture. 

 They have also a single spine on the outer edge. 



The second species, Pogonocerus hispidus, may be distin- 

 guished by the fact that it has two tubercles on the upper 

 surface of the thorax, one spine on each side, and the tip of 

 each elytron developed into two teeth, of which the outer is 

 the longer. There are also some little black patches of hair 

 near the tips, close by the suture. All these species have much 

 the same habits, and can be found among dry wood. 



The insect which is represented on Woodcut XXI. Fig. 5, 

 is called Rhagium inquisitor, and belongs to the family of the 

 Lepturidoe. In this family the eyes are nearly rounded, and 

 the antenna3 are of moderate length and set before the eyes. 

 The head is bent rather downwards and narrowed into a neck, 

 the thorax is narrower in front than the head, and the elytra are 

 gradually narrowed from the base to the tips. In the genu*
