Strewn in the hark l)t_-hin(l them, antl as tliey travel backward antl forward in 

 the biirritu' iVniii time to time, the httle stilt hairs with which their bodies 

 are [inuided ser\e as a brush to sweep this tkist into the egg notches. 

 Thus the nidutlis of these chambers are Idled and the eggs therein coveretl 

 and concealed. The female lorms a burrow from 4 to 8 inches or more in 

 length. 



Life history. L)r Fitch states that the eggs probably hatch in 10 to 20 

 days according to the temjjerature. The young grub is found King with 

 its back towards the sawdust with which the cavity in which the egg is laid 

 was filled, it thus being close to the soft innermost kucr of l)ark at the 

 e.xtremity of the notch. This cavity is continued b}' the larvae to a distance 

 of from I to 3 inches at a|)i)roximately right angles to the central gallery, 

 which latter increases in size with the develojiment of the grub. Those not 

 overtaken b\- disaster excavate an oval cell in which the final transformation 

 to the atlult takes place. The small beetles escape irom their retreats by 

 boring directh' to the surface of the bark.

A small brown or blat kish rylin(lri( bet-lie about 's inrh long may freipiently be 

 found boring the thinner bark "f smaller |iines and that of the limbs ol larger trees. It 

 is usually assoc ialed in this work with one or more species l)elonging to this genus. 



This bark borer is a medium sized form which was specialh' abimdant 

 in October igoo at Manor L. I., where it attacked the hartl pines which are 

 so abundant in that region. This beetle prefers the thinner l)ark of smaller 

 trees and also attacks the middle portion of the trindv and the limbs of 

 larger jiinrs. It is freiiuentl)' associated in its destructi\-e work with
