tions on forest insects had shown him that the large cerambycid larvae from eggs 
laid early in the season produced the pertect insects the next year; but those laid 
late passed two years before coming to maturity. He had taken a female of 
Monohammus confusor with the abdomen filled with eggs as late as the middle 
of September. The attacks of Nematus erichsonii on larches in the Provinces of 
Quebec and New Brunswick were described. 
Prof. Webster asked whether Agretis fennica had been observed feeding on 
cereals, 
Mr. Fletcher had found that it fed primarily on clover, but when occurring 
in numbers is almost omnivorous. Asparagus beds, raspberries and strawberries 
were injured and some young forest trees grown in nursery rows and of various 
species had had the terminal buds destroyed. 
Prof. Cook had found the larvee to eat everything. It had attacked blue 
grass and timothy severely. He was not positive about its attacking grain but 
believed it would. 
Prof. Smith, speaking of the best way to use pyrethrum powder, said that he 
had found it most satisfactory in water. 
Mr. Beckwith had found it could be used most satisfactorily with lime. 
Mr. Fletcher asked whether the dry powder was not asarule better than the 
water mixture. He had found it so in his experience. 
Prof. Cook and Prof. Gillette had found it so also. 
Prof. Summers found that the difficulty with water mixtures was to make 
them adhere to the plant: he asked whether the addition of soap would make 
them stick better. 
Mr. Fletcher said it would on such plants as threw off liquids by reason of a 
waxy secretion on the leaves, as the cabbage, etc., ete. 
Prof. Cook asked whether Mr. Fletcher still made up his cut-worm traps in 
bundles. He had found it most satisfactory to put a supply of poisoned vegeta- 
tion on a platform waggon and then pitch it off with a fork. 
Mr. Fletcher answered that he did and not only that but he found that it paid 
for the extra trouble to cover the bundles with shingles which kept them from 
drying up so soon. He warned those who advised this remedy to mention that 
the cut-worms do not lie under them in sight, but burrow beneath the soil and 
are not seen unless looked for. They sometimes wander off to a distance of two 
or three feet. 
Prof. Cook confirmed this. He used clover largely. He sometimes sprayed 
a patch with poison as it stood and then mowed it and used it as traps. 
Mr. Fletcher had found that clover was not the most satisfactory plant for 
him at Ottawa. It is frequently not far enough advanced in the early spring 
when needed and did not hold the poison well. He always recommended any 
succulent plant and was careful to tell farmers that they could use almost any 
weed growing about their fence corners, He had found Lepidiwm Virgvnicum, 
pepper grass, a very attractive plant. Chenopodium album, lamb’s quarters, is 
also greedily eaten by cut-worms ; but it is difficult to make the poison adhere to 
it. For such plants it is necessary either to dust them with dry powder after 
damping them or to rub up some soap in the water. 
Prof. Cook had found mullein to be a most attractive plant for cut-worms. 
The meeting adjourned to meet again next year at Washington.
