1905 ENTOMOLOGICAL SOCIETY. 



The foliage of many maple trees around Ottawa was this year badly at- 

 tacked by the Maple-leaf Gall mite, Fhytoptus quadriyes, on numerous fine 

 trees, the leaves being conspicuously distorted by the galls made by this tiny 

 mite. 



I have brought to the meeting a collection of Micro-Lepidoptera which I 

 have made at Ottawa and Meach Lake during the past two seasons. This year 

 I have mounted up nearly 1,500 of these small moths. I have also brought 

 some interesting larger moths, which are rare in the Ottawa District.

This has been a fine year for the entomologist, many species appearing 

 in numbers surpassing anything seen since 1898, and whilst that was the 

 Ciise with some species, very little injury has been noticed or reported to me 

 from injurious insects. Of course the Codling moth {Carpocaysa povionella), 

 the Potato-beetle {Dorypliora decemlineata) are always with us, and Onion 

 Maggots (Phorbia ceparum) and the Cutworms of various kinds were also 

 plentiful Mam est ra arctica in particular. I again note the scarcity of the 

 imported Currant-worm {Nematus rihesii), the Tent-caterpillars {Clisiocampa 

 Americana and disstria) and also the Tomato Hawk-moth (Proptoparce cel- 

 eus). The Cottony Maple Scale was noted on the maple trees, but not in un- 

 usual quantities; Asparagus-beetles have not reached us yet. No complaints 

 were received of the Pea-weevil. The Tussock moths were abundant this 

 fall, Antigua being by far the most plentiful. 



I have added a lot of new moths to my collection not yet identified. The 

 following I recognized, namelj^, Macronoctua onusta, Panclirysia purpurigera, 

 HadencL ducta, Perigea vecors, Remigia repanda, Prothymia rhodarialis, Ma- 

 rasmalus inficita, Noctua jucxmda, Ancyloxypha numitor, and a new Plusia, 

 making twenty-one species of this genus taken in Orillia. 



Butterflies were very numerous, Grapta J . album, Vanessa antiopa, Py- 

 rameis cardui and hunte{ra, and Atlantis very much more so than ever before 

 noticed. The Geometrids were also very much in evidence ; among several 

 new ones mention might be made of Phasiane Orilliata, Macaria glomeraria, 

 Plagodis alcolaria, and Philereme Californiata. 



On October 14th I tnok Remigia repanda, Aletia argillacea, Xylina an- 

 tennata, Orthosia ferruginoides, and Scopelosoma tristigmata. 



Division No. 3 — Toronto District. By J. B. Williams, Toronto. 



I was not well enough during the past summer to do much entomological 

 work, so that my observations on insect pests have been confined mainly to 

 the ravages of the Grey Tussock moth {Hemerocampa leucostigma) on the 

 shade trees in the streets of Toronto. (Figs. 3 and 4.) They were very num- 

 erous this year, especially on the horse-chestnuts. 



The city authorities spent some money in the collection of the egg masses 

 during the past winter, but there are so many infested trees in private grounds 

 that the destruction of eggs on shade trees only cannot effectually check them. 

 There are eight chestnut trees on the grounds in front of the house where I 

 live, some of which were partially denuded of their foliage by these cater- 

 pillars. Towards the middle of July, while sitting under these trees, one 

 could hear a continual patter on the grass as the creatures dropped them- 

 selves down from the branches ; and quite an army of them were creeping 

 about the ground for several days, while they sought for places to pupate. 

 Females emerged and began to lay eggs about the 5th of August.
