The Hickory Bark-beetle, ( Eccoptogaster spinosus ) , a much larger 

 species of the same genus, is destructive to hickory trees as far north as 

 Lake Erie. So far we have no evidence of any injury in Canada, although 

 I have seen specimens taken in Southern Ontario. It is similar in habit to 

 E. multistriatus. 



Moths of the Tent Caterpillar — Orchard above and Forest beloiv. 



The Leopard Moth ( Zeuzera pyrina Ivinne ) is another importation 

 from Europe, destructive to decidtuous shade-trees. Its large caterpillar 

 bores in the wood and has become a very serious shade-tree pest tluough- 

 out the region between New York and Boston. 



We should be on guard against importations of such destructive in- 

 sects; m.embers of this Society may have the opportunity to perform use- 

 ful service in reporting or directing the control of some of the enemies 

 just mentioned. 



We have, of course, quite sufficient troubles of this sort already, and 

 of these a few are briefly discussed here. 



The Forest Tent-Caterpillar. This tentless Tent-Caterpillar was ex- 

 tremely abundant in many parts of Quebec Province last season, 191 2. 

 With it were many of its near relative the American, or Apple-tree Tent- 

 caterpillar. The moths of both sj-ecies were extremely abundant and have 

 deposited myriads of egg-masses, which will give forth young caterpil- 

 lars in the coming spring (1913). The moths were attracted to the 

 lights of cities and towns, so that the shade trees of the streets and parks 

 in many places have their twigs simply plastered with the egg-masses. 

 Judging from our results in forcing several hundreds of these in the 

 laboratory there are few egg parasites, at least aJbout Ottawa; and unless 

 the weather conditions of tihe early spring are extremely unfavourable to 

 insect life, the season of 19 13 is likely to be remembered in many parts 

 of Quebec Province as "the Caterpillar Year."
