slioots, and this species, the Retinia turionana, is considered by the 
observer to be as hurtful as the R. buoliana, as in each case the shoot 
is spoiled, by the first named in the bud, by the second during 
growth of the shoot.

Pine Sawfly, chrysalis, and caterpillar magnified ; Pine leaves eaten by caterpillar. 
It is noted by Mr. D. Scott that on a detached estate to the East 
of Forres there has been attack (for the fifth or sixth year in suc¬ 
cession) from the Pine Sawfly. In the present season he tried the 
solution of soda and water mentioned at p. 44 of the Report for 1881, 
and found it was effective in clearing the caterpillar, but from the 
inconvenience of applying it in sufficient quantities he could not speak 
with certainty as to results. 
He also observed (as he had done in the previous year) that a cold 
wet day or two were very effective in causing the caterpillars to 
disappear. 
Mr. R. Coupar mentions that there was no attack of Pine Saw r fly 
this year at Colenden, Perthshire, but that further to the North he 
had observed a young Pine plantation of about ten years old which 
had suffered from attack last year, and which had been again attacked 
so severely this year that the young trees were completely stripped of 
their foliage. The ground on which the plantation was formed had 
for a long time before lain uncultivated and covered with heath and 
bracken ferns. 
The observer considers where the plantation is otherwise healthy 
and thriving that setting boys to hand-pick the grubs would be 
serviceable.
