ning, short -winged beetles, with the abdominal segments ex- 

 tending beyond the wing covers, are found in the galleries 

 of Pendroctonus, Ips and other bark-borers, feeding upon 

 the eggs of the several species. 



Various other beetles are found in the galleries 

 of the bark-borers, but while sxipposed to be predaceoxis, 

 little is known of their habits. 



CONTROL. 



Control work in District 5 was systematically 

 begun in 1912 on the Flamath National Forest. This work con 

 sisted of two projects known as the Craggy and Barkhouse. 

 927 trees were cut and btirned. The infestation, largely in 

 yellow pine, was caused by the Western Pine Beetle (Pendroc- 

 tonus brevicomis). This work was followed up in the spring 

 of 1913 by a recleaning on the Craggy Project, v-here 178 Ad- 

 ditional trees were burned. Just previous to this in the 

 fall of 1912, work was commenced in the Trinit2/- National For- 

 est on what is known as the Hayfork Project. It was con- 

 tinued in the spring of 1913 with a total number of trees 

 cut and burned, amounting to 1553. This was also a yellov; 

 pine infeststion with the additional factor of many poles rn 

 saplings killed by a flathead borer (Melanophila gentilis).
