FOREST ENTOMOLOGY. 



The beetle (fig. 113) is elongated and cylindrical, of pitchy brown 

 colour. The thorax is darker than the elytra, and longer than broad. 

 Legs rusty brown colour, and the antennae and tarsi lightish-yellow. 

 In the male the apex of the elytra is much inflexed, with a tooth 



on each elytron, and the suture is so raised 

 on the inflexed portion as to form a small 

 keel. 



In the female the apex is most feebly 

 inflexed, and the extreme apical edges are 

 rounded. 



Genus Dryocetes. 



The genus Dryocaetes may be said to

 The whip of antennas five-jointed ; elytra distinctly punctured, and 

 covered with fine pubescence and smooth. 



Dryoc^etes villosus (F.) 



I found this species very plentifully in the rough bark of an old 

 dead standing oak in Chatsworth Park, Derbyshire. I have also, more
