356 THE CANADIAN ENTOMOLOGIST 



Trypodendro7i {Xyloterus) lineatiis Oliver. 



The true lineatus seems to be very rare, though a closely 

 allied species is common. I have what I believe to be the true 

 species from Seaside, Oregon. They were picked up on the beach 

 during a storm in December, 1916. 

 Trypodendron (Xyloterus) politus Say. 



There is a single specimen in the College collection bearing 

 the label "Huntington, Oregon." Probably erroneously labeled. 

 Trypodendron rufitarsis Kirby. 



A number of specimens collected from Finns contorta, near 

 Sumpter, Oregon, July 14, 1914. 

 Trypodendron, n. sp., near rufitarsis. 



Collected from living Douglas fir at Breitenbush Hot Springs, 

 April and August, 1914. 

 Xylehorus dispar Fabr. 



In orchard trees; Portland, Salem, Corvallis, Oregon City, 

 and Eugene; April to June. 

 Xylehorus xylographus Say. 



Specimens assigned to .this species taken- from Oak (Quercus 

 gerryana) and Douglas Fir (Pseudotsuga taxifolia) at Corvallis. 

 Platypus ivilsoni Swaine. 



Abies grandis, Corvallis; A. nobilis, Elk Lake; Tsuga hetero- 

 phylla, Detroit, and Pseudotsuga taxifolia at Corvallis and Ranier. 



Editor's note. — Mr. J. M. Swaine has informed me that Ips 

 wieslanderi Swaine, which was listed in the first part of Mr. 

 Chamberlin's paper (p. 327) is an old manuscript name for the 

 species described as Ips radiata Hopkins. 



Leperisinus acideatus Lee. (p. 328) and Hylesinus aculeatus 

 Say, (p. .326), are synonymous, and should be listed under the 

 latter name.
