and the larval galleries extend above anrl below the trans- 

 verse egg gallery. These egg galleries are clear of sawdust 

 and notched, an egg being placed in each notch. Fresh un- 

 peeled down timber is peculiarly susceptible to its attacks 

 and evidence of work is often located by sawdust around the 

 entrance holes. The abdominal segments do not extend as far 

 as the v/ing covers, giving the beetle a cut-off appearance 

 underneath the apical portion of the elytra or wing covers. 

 This is common to all species of the genus Eccoptogaster 

 (formerly Scolytus). The species may be' located by the host 

 tree and the snail chamber from which the egg gallery is pro- 

 duced in opposite directions and the cut-off appearance uncle: 

 the wing covers in connection with the host tree. 



HYLE SINUS, n. ep . 

 Host - White Fir. 



This beetle kills many firs of mature growth. The 

 beetle is slightly variegated, groy and black, and about the 

 size of Dendroctonus brevicomis, but more robust in form. 

 The egg galleries are transverse but without the chamber und< v 

 neath the entrance hole as in Eccoptogaster. The gallery is 

 produced in opposite directions from the entrance hole, note.', 

 ed and eggs deposited in the notches. The larval galleries
