North American fall wcliworiiis, II. H. I>yiiian (pp. 57-62). The autliur gives 

 short notes on the haliits ami life histoiy of a nnmber of species of Hyphantria, 

 with tal)les in<licating the months in which they appear in various stages and in which 

 they are most injurious. 



The trend of insect diffusion in North America is discussed by F. M. Webster 

 (pp. 63-67) . A map is presented showing the general directions of the movements 

 of insects in different parts of the country at the jiresent time. The same author 

 (pp. 67-74) also read papers on the imported willow and poplar curculio and on the 

 common cheese mite, which is reported as living in cultures of SporotrlcJmm 

 glohuliferum. 



The hiV)ernation of insects, W. Lochhead (pp. 74-78) . Lists were compiled by 

 the author of insects which hibernate in larval, pujial, adult, and egg conditions. 



A paper was read by J. A. Moffat on the archippus butterfly (pp. 78-82), in which 

 evidence was presented to show that this butterfly does not hibernate in the adult 

 form and that the peculiar ccjUections of this species, which are sometimes observed 

 in autumn on bushes or trees in Northern altitudes, are also seen in the South, where 

 the purpose of this collection is not hibernation. 



The following papers were also presented at this meeting: Collecting at Light in 

 1901, J. D. Evans (p. 82); The Milkweed at Dusk, A. F. Winn (pp. 82-84); A Col- 

 lecting Trip in Southwestern Ontario, by E. M. Walker (pp. 85-90); Crickets, by 

 T. W. Fyles (pp. 90-94); Nature Study Lessons on Mosquitoes, by W. Lochhead 

 (pp. 94-98) ; Entomological Record for 1901, by J. Fletcher (pp. 99-108) ; Commercial 

 Entomology, by C. Stevenson (pj). 113-115); and The Food of the Grass Snake 

 {Liopeltis vernalis), by J. B. Williams (p. 115). 



At the third annual meeting of the Northwest Entomological Society the president 

 of the Society, in his annual address, presented short notes on a number of injurious 

 insects, includirig cabbage butterfly, tent caterpillars, crane flies, horse botfly, and 

 Colorado potato beetle. 



Bioirraphical notes of Eleanor A. Ormerod and O. Luggar are also presented. 



Report of the entomologist, J. Fletcher ( Canada Expt. Farms Epts. 1901, pp. 

 196-252, figs. 18). — The author gives brief descriptive notes on the conditions found 

 in various parts of Canada during a trip of inspection. The insects which were most 

 injurious to cereals during the year were grain aphis, wheat-stem maggot, Hessian 

 fly, cutworms, and grasshoppers. The ravages of the Hessian fly on winter wheat in 

 Ontario were more serious tlian they had been for many years; Ijarley also suffered 

 considerably in a number of localities. Notes are given on the extent and serious- 

 ness of the attacks of the Hessian fly in different parts of Canada, as reported by 

 various farmers and voluntary observers. The time to sow winter wheat so as to 

 avoid as far as possible the attacks of the Hessian fly can not be fixed for all years, 

 but must be regulated acc;ording to the season rather than the almanac. Apparently 

 it is not safe to sow wheat in the counties bordering on Lake Erie before Septem- 

 ber 15. During the year the most widespread and disastrous outbreak of cutworms 

 which had ever been reported for Manitoba occurred in various parts of this Province. 

 The cutworm chiefly concerned in this injury was Carneades ocJwogasier. Snnilar 

 injuries were caused to grain in Ottawa by Iladena devastatrlv. Various kinds of 

 grain were eaten down to the surface of the ground, or in some cases cut off beneath 

 the surface. The poisoned bran remedy is recommended for future outbreaks of this 

 sort. Locusts of various species also caused considerable loss, especially in central 

 Manitoba and British Columbia. The species concerned were chiefly Melanoplus 

 adanis, M. packardii, M. bivlttatus, and Cannnda pellncida. One of the most successful 

 remedies in combating these insects was found in the use of a poisoned bait consisting 

 of fresh horse manure, salt, and Paris green. The locusts were easily attracted to 

 this bait, and when it was scattered around the edge of grain fields and thrown into
