NOTES OF OBSERVATIONS 
as well of the branches as of the main leader of the tree, and 
causing a stunted and deformed growth. He also mentions the best 
remedy he is acquainted with to be hand-picking, so long as the 
shoots are within reach. In many cases the damage to the special 
tree observed is done before the presence of the insect is detected, but 
even then if destroyed the number is lessened for the succeeding 
season. June and July are the best months for examining the trees, 
and one man can look over a large number ; and to a continuance of 
this treatment for some years with many thousand trees Mr. Matheson 
attributes his present comparative freedom from the Tortrix. Mr. 
Herbert Morrell contributes a description of the attack of one of the 
Pine Tortrices on his Austrian Pines at Headington Hill Hall, near 
Oxford. He mentions that these Pines, when from two to six feet 
PtETINIA Turionana. 
high, are almost all attacked by some insect of which the preliminary 
workings are not noticeable until (as about the end of February, at 
which his communication took place) a gummy exudation is noticeable 
at the base of the leading bud. In 1878 the injured buds, which 
showed a minute hole at the lower part, remained green till about the 
end of March. About May these buds were brown, and broke off 
easily to a touch, showing the grub within, occupying the whole of the 
bud and part of the stem beneath. Absence from home prevented the 
completion of the observation by capture of the imago, but it is 
obviously one of the Pine Tortrices ; and it is mentioned by Mr. Morrell 
as spoiling hundreds of Pines in his new Plantations, invariably 
selecting the leading shoots; fortunately, however, leaving the 
P. exceha and Spruce Fir untouched.
