The long cold rains that succeeded the hot spell in the beginning of July apparently 

 were too much for most of the destructive cut worms, as their imagoes did not appear 

 (with the exception of Agrotis teli/era, Fig. 49,) in any numbers. Hadena devastatrix 

 and arctica and Leucania unipimcta, the army worm motb, were almost scarce — in 1896 

 unipuncta was so plentiful that I have killed over 500 on one post, on which I had placed 

 my sugar for other victims ; they were a perfact nuisance, coming in clouds before dark, 

 and this occurred in June and again from the end of July through the season ; notwith- 

 standing this fact, the army worm was .not reported as troublesome in our county, though 

 I believe Ontario county was infested to some extent.

The following noxious insects were reported as plentiful around Orillia : 



The tent caterpillar, Clisiocampa Americana. Fig. 19, also its confrere (sylvatica) 

 the former, however, only lives in the neglected orchards, but the moth was extremely 

 abundant. 



The canker worm (Anisopleryx pometaria). — I never saw such quantities of this 

 insect in the imago state as this year; in October it was to be found, male and female, 

 on every roadside fence — with it was also conspicuous Hybernia tiliaria, the November 

 moth, Fig. 50. 



Carpocapsa pomonella, the apple codling moth, — this insect, though not often seen 

 as an imago, is always plentiful here, but sprajing the trees has had a wonderful effect 

 in controlling this pest, and those orchards that are sprayed regularly every year produce 

 as sound fruit as is to be found anywhere.

The Woolly plant-louse 

 of the apple (Schizo- 

 neura lanigera). 



Orgyia leucostigma, the tussock moth (Fig. 51), is evidently on the increase in 

 Canada, from observation made here by myself. It seems that each year it is rather more 

 plentiful. Orgyia antiqua. — This insect appeared in numbers this fall. I bred several 

 females and whilst they were confined in the cage the air for y h rds around was literally 

 full of the attendant males.
