1903 ENTOMOLOGICAL SOCIETY. 31 



The following exhibits were shown by those attending the meeting : 



By Dr. James Flefcher : Apoclbeima Rnclielae in all stages from the egg to the perfect 

 nsect, with inflated larvae ; Lencohrephos Middendorfii, in all stage.s ; Gliionohas Alberta with- 

 out any ocelli above cr below ; Gynaephora Rossii, bred by Mr. Percy B. Gregson, from larvae 

 found at Blackfalds Alta., also mature larvae collected this year at the same place. The type 

 specimen of Catocala unijuga, var. Fletcheri, Beutenmueller. 



By Mr. Arthur Gibson : A complete collection of the Arctian moths of the genus Apant- 

 esis 80 far recorded from Canada, and referred to in his recent paper. Also a collection of 

 about fifty inflated larvae of lepidoptera. 



By Dr. Bethune : The remarkable beetle found by Mrs. Slosson in New York (Can. Ent. 

 XXXV, page 183, July 1903) which has not yet been identifier!. 



By Dr. C. H. Young : A fine collection of inflated larvae taken during the season, or reared 

 from the egg — all local (Ottawa) species. About fifty noctuidae taken at Ottawa miny of 

 them not previously recorded from that district. ' Also a fine female specimen of Erebus odora 

 taken at sugar. 



By Mr. Lyman : The remarkable aberrant forms of two moths, referred to in his pxper. 



By Mr. J. D. Evans • A box of moths taken at Trenton including among other rarities 

 Apatelodes anyelica. 



By Mr. A. E. Norris, Montreal : Box of moths including Cossvs centerensis, Hydrcecia 

 rntila, stramentosa, marginidens, purpurifasc'ia , cerussata, and Cressonia juglandis. 



Specimens were also exhibited by Mr. Stevenson and Mr. A. V. Winn, of Montreal, and 

 Mr. J. B. Williams, of Toronto In addition to the^e there was exhibited a specinun of a 

 Blue Lizard, the only species taken in Canada. 



INSECTS OF THE SEASON. 



Bv W. Lof'HHEAij, Professor of Biology, Ontario Agricultural College, Guelph. 



From my own observations and from reports obtained from most sections of the Province, 



it is evident that the injuries done by insects this year have been below normal. The causes 



which lead to the decrease or increase in the number of injurious insects for any particular 



season are not well determined. We still require to make many observations ar.d to make 



more thorough search into insect life at all stages of the year before much head-way can be 



made in determining the causes. We must note, however, that the seasons of 1902 and 1903 



were both cold and wet, and when we bear in mind that this combination of conditions is very 



harmful to larval life it is probable that some of the causes for the dearth of insect life during 



these seasons have been determined. As in my previous reports I shall deal with the injurious 



insects according their host plant. 



Cereal Crops. 



Hessian Fly. Cereal crops have not been disturbed much by insect life. The Hessian 

 Fly scourge which did so much damage in 1 900 was not evident, and in most localities was 

 almost entirely absent. This hapjiy condition of things is due to the action of the farmers 

 themselves in accepting the advice of the entomologists who had studied this question quite 

 thoroughly. The farmers had got into the habit of planting their fall wheat too early. In 

 some of the central counties in the south-western part wheat was sown as early as the 20th of 

 August. Experience soon convinced them that the entomologists were right, and that they 

 were working in league with the Hessian Fly by planting their wheat at that date. Late 

 planting is now the rule in most sections, and from all reports the crops are just as heavy as if 

 they had been sown two or three weeks earlier. 



Wheat Midge. In early spring there was a fear lest the Wheat Stem maggot would 

 become destructive this season, for many fields showed evidence of being badly infested. 

 Through some cause or other the pest did not make headway, and it is probable that very 

 little damage was done.
