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 speci- 
mens were found in Cambridgeshire, England. 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 be Sirex cyaneus. The typical race is European, living in 
Seoteh fir (Pinus sylvestris). It differs little from cyaneus, 
having however the base of the antenne red instead of black. 
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 
abbotu as the male of cyaneus, and he considers varipes syn- 
onymous. S. duplex was not supposed to be 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- 
sonian 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 S. 
cyaneus.
