THE REPORT OF THE 



No. 19 



I offered a small sum to several boys on the street if tliey would clear the 

 cocoons oft' those eight trees. Some of them were good climbers, and they col- 

 lected, I believe, about two buckets full. The trees are now, apparently, free 

 from them, and it will be interesting to observe next season to what extent 

 this clearing has been effectual, for there are no other chestnut trees near 

 them.

Walking-stick insects {DiaylieroTriera feviorata), which were so numerous 

 in some localities last year, have only appeared this year in about their ord- 

 inary numbers. 



Tent caterpillars, as far as I have noticed, have been comparatively scarce 

 around Toronto, and Dr. Brodie's observations also confirm this statement. 



I heard one complaint of apples, from a garden north of the city, having 

 worms in them, but I had no opportunity to examine any of them. 



Division No. 5^-London District. By C. J. S, Bethune. 



At the request of Professor McCready, whose appointment to the chair of 

 Nature Study at the Macdonald Institute, Guelph, caused his removal from 

 London last winter, I beg to make a report upon the noteworthy insects of the 

 l)ast season in that part of the country. 



In the city of London itself public attention has been especially drawn 

 to the widespread abundance of the Cottony Maple Scale {Pulmnaria innum- 

 erahilis, Eathv.) on the shade trees of the streets and boulevards of the city. 

 (Fig. 5.) On the maple and basswood trees especially it was to be found in 

 countless nullions, snd the cottony tufts of egg-masses on the underside of 

 twigs and branches were so numerous and so close together as to look as if 

 the boughs had been thickly iipattered with whitewash. Towards the end of 

 August the leaves on many trees were curled and withered from the continu- 

 ous drain of the scale insects and began to fall prematurely; in some in- 

 stances the trees were almost bare by the first of September. Grape vines, 

 the Boston ivy, Virginia creeper, and many shrubs were included in the at- 

 tack, and injury was also caused to plants and flowers by the constant drip 

 of "honey dew" and the black fungus that grew wherever it fell. This at- 

 tack has been going on for some years and steadily increasing in extent, and 

 now it seems to have reached its culmination, and, we may hope, may begin to 

 decline. Two years ago at our annual meeting, I gave an account of this
