were common at Bend, May 19, while larva^ and pupae were found 

 at Ashland, June 20. Many were found dead, imbedded in pitch 

 on the stumps. The egg galleries are usually 7 to 8 inches long, 

 though it is not uncommon to find them 12 to 18 inches or 

 even more in length. These galleries are usually fairly straight^ 

 running parallel with the grain of the wood. Occasionally they 

 are irregular, crossing and recrossing other galleries, making a 

 complex pattern. The typical work consists of an irregular 

 round chamber, about half an inch in diameter from which the 

 egg galleries run up or down the tree trunk. Each female has 

 her own gallery in which 20 to 40 eggs are deposited along the 

 sides and carefully covered with fine borings. 

 Ips pini Lee. 



Reported from Oregon by Leconte in 1868. 

 Ips interriiptus Mannh. 



A single specimen taken from Picea sitche^isis at Marshfield, 

 Oregon. 

 Ips inter punctatus Eich. 



Collected from Pimts contorta on the Whitman National 

 Forest in July, 1914. 

 Ips concinnus Mannh. 



This species ordinarily attacks Finns contorta and Picea 

 sitchensis, and it was \'ery unusual to take several adults from a 

 fire-injured Douglas fir sapling at Astoria in April, 1915. This is 

 probably an accidental host, and it is interesting to note that the 

 broods failed to develop. 

 Ips ccelatus var. • ^ - 



Collected from Picea engelvianni. Grant County, Oregon, 

 June, 1914. 

 I ps confnsus Lee. 



Occurs in the extreme southern part of the State in pine. 

 Leperisinus aculeatus Lee. 



A single specimen collected at Corvallis. Host not known. 

 Orthotomiciis ornatus Swaine. 



A few specimens taken from Pinus ponderosa on the Whit- 

 man National Forest, July. 1914. 



(To be continued.)
