208 BRITISH BEETLES. 



behind. It loves to settle on felled pine logs, with its 

 antennse spread out like compasses ; from which habit it 

 is termed by the Highlanders " Timberman ;" a name, 

 curiously enough, also applied to it in Lapland and 

 Sweden, where it is common. If two males come within 

 range they inevitably fight; for which reason, and also 

 on account of their delicate structure, it is difficult to 

 obtain quite perfect specimens. 



The larva makes wide galleries and perforations in 

 pine stumps, forming a nidus with coarse gnawed frag- 

 ments near the surface, in which it changes to pupa. 

 In this state the antennse are turned downwards and 

 recurved towards the middle of the head. The larva 

 appears to be full fed at the beginning of the summer, 

 and, after remaining two or three weeks in the pupa 

 state, changes to the perfect state; staying as such in 

 its nest until the following summer. 



The species of Pogonocherus are very much smaller, 

 having the elytra slightly hairy, generally spined at the 

 apex, and with the front greyish-white. They are beaten 

 out of bundles of old twigs and faggots in hedges. 



In the Saperdides, which are all more or less cylin- 

 drical, the femora are not clavate ; and the thorax, which 

 has no spine at the sides, is continuous in outline with 

 the elytra, being, moreover, deeply sinuated on the sides 

 beneath. 



Here are situated some of our most handsome species ; 

 notably Saperda scalaris (Plate XIII, Fig. 5), a very 

 beautifully coloured insect, occurring near Manchester 

 and at Eannoch. 



Of the other Saperda, which appear to affect aspens, 

 poplars, and willows, carcharias (found in fenny dis- 

 tricts) is remarkable for its large size and uniform yellow-
