Shuckard makes the identification of the male certain, as he 

 notes its occurrence with the female in the spruce fir {Pinus 

 [Picea] nigra), which is an American fir, although the sjieci- 

 mens were found in Cambridgeshire, Klngland. He states that 

 they last about a fortnight during the latter part of May and 

 early June. He mentions the confusion existing in the identifi- 

 cation of the species, and correctly suggests that it may prove 

 to he Sirex cyaneus. The t^1^ical race is European, living in 

 Scotch fir {Pinus sylvestris) . It differs little from cyaneus, 

 liaving however the base of the antennae red instead of l)lack. 

 Mr. Ingpen relates the occurrence of cyaneus in England by 

 thousands in the boards of a house which had been built three 

 years; the lumber was supposed to have been brought from 

 Canada. 



Konow in his monograph of the Siricini incorrectly places 

 (ibbotii as the male of cyaneus, and he considers varipes syn- 

 onymous. S. duple:v was not supposed to he new when de- 

 scribed, but was so treated on account of the confusion in 

 regard to it, and was thought possibly to be S. cyaneus. 



Distribution: From northern New York to New Brunswick, 

 Newfoundland and Hudson's Bay, west to Vancouver Island, 

 south to Illinois and Kansas, south along the Rocky Mountains 

 to New Mexico, and along the Pacific Coast to California. A 

 characteristic species of the Canadian and possibly also Hud- 

 soniau life zones. 



Sirex nigricornis Fabricius 



Konow has placed pinicola Ashmead as a synonym of nigri- 

 cornis. There seems, however, to be a more or less constant dif- 

 ference in the color of the posterior legs, and it seems that 

 pinicola represents a southern race of the more northern nigri- 

 cornis, the two meeting in the region of West Virginia and 

 Delaware. 



Norton states that males taken in the same locality as the 

 female were almost precisely the same as the males of 8. 

 cyaneus.
