LONG HORNED BEETLES. 123 



are in constant motion when the beetle is running about and 

 point forward in this case ; when the owner is asleep they bend 

 backwards, and are close to the body. 



The larva bores in the sound wood of pine and fir, making 

 vvhen full grown, a large hole, half an inch in diamater. It 

 changes to a pupa, and soon afterwards 'to the adult beetle. 

 Such borers are exceedingly numerous in our neglected pine 

 forests, invading all the trees that are injured by fire, or which 

 are bruised by trees felled by the axe of the wood-cutter. When 

 everything is quiet the gnawing of such larvae can be plainly 

 heard in the dry trees, which act as a sort of a sounding board. 

 This insect is shown still in its burrow in Fig. 128. 



There is another insect, not as bulky, but nearly as long, with 

 equally long horns, which in the Southern States is quite des- 

 tructive to the mulberry. Our mulberry bushes are also invaded 

 by a similar, but mnch smaller bee'tle, which is, however, not 

 numerous enough to cause much injury. 



The hickory is invaded by a number of borers, which in 

 more southern regions cause the loss of many young trees. The 

 Common Hickory-borer (Goes tigrinus De Geer), and the 

 Beautiful Htckory-borer (G. pulchra Hald.), as well as G. 

 oculaius Lee. and G. debilis Lee. belong to this genus. 



the beautiful hickory-borer. 

 (Goes pulchra Hald.). 



This insect (Fig. 129, Plate VI) is well named pulchra, mean- 

 ing beautiful. It measures a little over an inch in length, is reddish- 

 brown, and marked with dark brown in such a manner that across 

 the wing-covers a band is formed, which gradually shades off 

 into the general color of the beetle towards the tip. This mark- 

 ing of 'the wing-covers is produced by a close belt of fine hairs. 



The beetle deposits eggs upon the different kinds of hick- 

 ories, frequently selecting for this purpose the smaller trees, an 

 inch or more in diamater. The presence of the larvae inside
