PLATE 15 



THE TIMBERMAN. 



Page 120 



This wood-boring beetle is distinguished by his pair of fine antennae. Those of the 



female (above) may be described as long, but those of the two contending males 



are very much longer. This beetle is very destructive to pit props in coal-mines. 



The grub and the chrysalis are shown in the lower part of the picture.
