 roy River (Bolster) ; Alaska, Vancouver, Manitoba, Great Slave 

 Lake; northern Europe, Siberia, the Amur (Hamilton). 



165. Dendroctonus borealis Hpk. (:= rufipennis Mannh.) 



Mr. Schwarz writes: "Your Labrador Dendroctonus has been 

 determined by Dr. Hopkins as borealis Hpk., a species of great inter- 

 est in regard to geographical distribution, since it was recorded pre- 

 viouslv only from the north Pacific coast." Alaska: Eagle, and 

 Kenai. 



166. Dendroctonus terebrans Oliv.

Addenda. 



Two small lots of Labrador beetles received from Red Bay this 

 summer contain examples of three species not mentioned in the fore- 

 going list. The species are: 



167. Tachinus parallelus Horn. 



One specimen, male, " smaller than my females from Mt. Wash- 

 ington " (Blanchard). This species is on the Bowditch list of Mt. 

 Washington species. Mr. Blanchard remarks that Tachinus elon- 

 gatus Gyll., a European species, recorded from Alaska also, must be 

 very near parallelus Horn. 



168. Neomysia subvittata Muls. 



Two specimens. " A new variety, which does not agree exactly 

 with Mulsant's description, nor with either of the two forms described 

 by Casey " (Leng). 



169. Hylobius confusus Kirby. 



One specimen. Red Bay. Mt. Washington, N. H. (Bowditch 

 list), Alaska, Lake Superior, New York, Massachusetts (Hamilton).
