 branches, 3^ to 1 inch in dianleter. Occasionally larger limbs were 

 found attacked. Living, dying and felled yellow pine (Pimis

 rough circular chamber 14, to 3^ inch in diameter is eaten out, 

 from this radiate 5 to 8 egg galleries 3^ to 13^ inches long. The 

 eggs are pearly white, slightly less than 1 mm. long, oval, buried 

 in the frass. Adults, young larvae and eggs were collected May

 Pityophthorus confinus Lee. 



Swaine (N. Y. S. Mus. Bui. 134) gives the range of this species 

 as transcontinental and gives Washington and California, so the 

 species undoubtedly occurs in Oregon, though I have never col- 

 lected it.

Bi-ed from pine cones collected at West Port, Oregon. Cones 

 collected August 20, and adults emerged September 11. 

 Pityophthorus nitidulns Mannh. 



A widely distributed species which is found in dying Pinus, 

 Picea and PseJidotsuga, throughout the State. 

 Pityophthorus, n. sp. 



A' species similar to nitidulus but larger and darker has been 

 collected a number of times from Abies grandis and Abies nobilis; 

 from the former tree in the valleys, from nobilis in the Cascades.
