Life history and habits. ALlults of this species ha\e been observed 



ovipositini^ on recenth' sawc-tl spruce liinihcr, and Dr Hopkins states that it 



attacks spruce, hemU)ck and tir. 1 his is one ol the more c(.)ninion (jf our 



species in the eastern United States, though it is far from abundant and the 



male appears to be quite rare. The adidts are usuall)- found duriuL^' July 



and Autrnst on the trunks of coniferous trees on briLrht days. The etrtr^ 



are deposited in the wood with the stout ovipositor, the insects apparently 



preferring recently felled trees. 7die larvae run large burrows through the 



trunks, often rendering them untk for luml^er. 



Distribution. This species has been recorded by Fabricius from both 



North and South /Xmerica. It has in addition also been reported from the 



following localities: New England, New York, New Jersey, Louisiana, 



Washington, Ottawa Can., Lake Winnipeg, Newfoundland and Northwest 



Territory. It has also lieen taken in England, probably carrietl there in 



infested linnljer. Some allied sjjecies are regarded as tlestructive to pine 



forests in German)', and reports of considerable injuries to coniferous trees 



have been received from the Northwest Territory, though we believe that, 



as a rule, in this country comparatively little damage results from this 



insect's work.

Banded horntail 



Uroicrns abdoniiiialis Harr. 

 A lar.ue, lil.n k, 4-u-ingL'd lly an in( h long having some resemblance to a wasp, hut 

 with a stout, ( yliiulric body, attacks sprui e. 



This species has smoky, transparent wings and its lar\ae have the gen- 

 eral character of other horntails. The different sexes of these insects vary 

 considerably, antl it is possible that this species is the male of U rocerus 

 a 1 b i c o r n i s Pabr. noticed above.
