1914 ENTOMOLOGICAL SOCIETY. 49 



Along a by-road leading to the estate of the late CoL Calvin Hall in East 

 Earnham a row of white elms had been planted. When I took notice of them, 

 they were about fifteen feet high. It was in the Fall of the year, when, from some 

 cause or other, the leaves of the elm curl o^'er, and form rolls, on which the veins 

 of their under sides are very conspicuous. 



The trees I speak of had been visited by the Sphinx, Ceraiomia amyntor 

 Hubner, and I found a number of the larvae of this insect feeding upon them. 

 Strange to say, the larvae took positions in which they closely resembled the rolled 

 leaves — the ribbed sidelines of the caterpillars mimicking the veins of the leaves. 



As the season advanced, tho leaves of the elms changed from green to rusty 

 brown, and a corresponding change took place in the colour of the larvce. 



But it is time I brought this paper to a close. It is one of reminiscences — a 

 record of days gone by. I have written it in the hope that some into whose hands 

 it may fall may be led by it to take a deeper interest in Nature Studies, to per- 

 ceive a little more clearly some of the beauties in God's marvellous works, and to 

 look up with deeper feelings of love and reverence to Him, for whose pleasure all 

 these things are and were created. 



INSECTS OF THE SEASON IN ONTARIO.

With a few exceptions there have not been many complaints this year of 

 serious injury from insect pests. 



Orchard Insects. 



Codling Moth {Carpocapsa pomonella) . Each year, even in the most favor- 

 able localities for development, adds to the number of those who are proving that 

 one thorough spraying just after the blossoms fall will control this pest. There is 

 no doubt that in old apple orchards the use of gasoline outfits with high pressure 

 has been one of the main factors in obtaining this result. The percentage of 

 infestation this year was high in a few of the warmer districts, due rather to the 

 crop of apples being much smaller than usual than to any excessive number of the 

 insects themselves. 



San Jose Scale {Aspidiotus perniciosus) . A good many complaints of 

 damage being done by this, our worst insect pest, have been received. This was 

 largely due to the difficulty last spring of getting on the land in time to spray 

 affected trees thoroughly. In some cases old orchards were not pruned and scraped 

 before spraying and consequently it was impossible to do a good job. In a few 

 cases the mixture used may have been too weak. 



Plum Curculio (Conotrachelus nenuphar). This insect was not nearly so 

 prevalent as usual in most parts of the province, though in some neglected apple 

 orchards in Prince Edward County it was very abundant and had attacked most 

 of the fruit. The surroundings here were specially favorable.
