work under ground it is difficult to find a remedy tliat will be effective. 

 Much, however, may be done to reduce their numbers by trapping them. This 

 is done by placing bunches of clover or sweetened meal poisoned with Paris 

 green under shingles or pieces of board where they are troublesome. The 

 insects are in the habit of taking refuge in the daytime beneath shelters of 

 this kind and will naturally partake of the poisoned food they find provided 

 for them. 



The 12-spotted Asparagus beetle {Crioceris 12 -punctata) is becoming each 

 year more and more numerous in gardens about London. The other species, 

 C. asparagi, has not yet made its appearance. Dusting with air-slaked lime 

 seems to be the simplest and most effective remedy for getting rid of the 

 larvae which feed upon the foliage during the summer. 



The Fall Web-worm (Hyphantria textor) has been somewhat in evidence 

 with its unsightly webs on some trees here and there on the city streets, and 

 on many shrubs and trees in Springbank Park. As soon as the Super- 

 intendent's attention was drawn to them, they were speedily got rid of 

 in the Park, but on private grounds many were left unmolested. It 

 is such an easy matter to remove the webs with a stick, and destroy the 

 inmates by trampling under foot, that there is no excuse for neglecting 

 them. It is true that they generally inflict but little damage upon the trees 

 owing to the lateness of their attack, but they are very unsightly and are 

 sometimes very injurious to young trees and shrubs. 



The CodlingMoth is reported to have been more prevalent than usual 

 this year and, to have considerably affected the apple crop about London. The 

 itcrease of this serious pest is no doubt due to the neglect of spraying, and 

 possibly to ignorance of the fact that there are two broods in the year in this 

 region of country. 



The Pea-weevil, on the other hand, is very little complained of, and could 

 be effectually checked if a combined effort were made by all growers and 

 seedsmen. Fumigation with bisulphide of carbon is an easy remedy and not 

 expensive. Its general adoption would soon restore the growing of peas to the 

 valuable position it formerly held in Ontario. 



Regarding the Hessian fly, no complaints at all were heard and evi- 

 dently no appreciable damage was done. 



Cutworms, Squash-bugs, Onion and other root maggots were as preva- 

 lent as usual and gave the market gardeners much trouble. On the whole 

 the season was not marked by any unusual or violent outbreak of insects, with 

 the exception of the Cottony Maple »Scale already referred to. 



DISCUSSION OF THE DIEECTORS' REPORTS. 



The Tussock moth was the first insect taken up for consideration. 



Mr. T. D. Jarvis stated that at St. Catharines and in Toronto eighty per 

 cent, of the cocoons that he examined were parasitized by Pimplas and Chal- 

 eid flies. 



Prof. J. B. Smith explained that one of these classes of insects was a sec- 

 ondary parasite upon the other, and could not, therefore, he credited with 

 aiding in the reduction of the Tussock moths, but rather the contrary. 



Mr. C. W. Nash said that the Tussock moth was by no means confined to 

 cities, as he had found them abundant all through the County of York and 

 even as far away as St. Joseph's Island in Lake Huron. There he had found 

 a female depositing its eggs as late as the 8th of October. His experience was 

 \ery different trom that of Mr. Jarvis, for he had only found one cocoon in 

 400 narasitized ; many, however, were diseased and their contents had become 

 fluid.
