The beetles appeared in June. The other was a small Scolytid, probably Hypothenemus, which made short galleries in the extreme tip of the twigs infested by the Longicorn larva. It is probable that this attack is secondary, and not made while the wood was sound. Some discussion was had at our last meeting concerning the points of the tree attacked by the larva of Saperda Candida. (Fig. 15.) This led me to observe carefully during the present season, and I find that while in quince the attack is almost exclusively at the base of the tree, in apple and pear, any part of the trunk and even the larger branches may be attacked. The larvie are more numerous at the base, as a rule, but the other localities are not by any means exceptional. I know that no other larvaj were concerned, because I cut out pupaj and imagos as well, and am certain of my facts. Peach borers, the larva? of Sannina exitiosa (Fig. 16), are now largely treated by mechanical coatings to the trunk. The favourite means is the onerecom- I mended by me in the bulletins of the station and at farmers' simply a thick whitewash with glue added. I have never discouraged the use of other mechanical coatings, but have taken great pains to explain that no remedial results must be expected ; that the measure was protective merely. The use of paint, as suggested by Mr, Alwood, does not find favour, owing to a fear that injury may result to the tree. Blackberry insects have been particularly observed ; but as I have already described these, a mere mention here is all that is needed. The Eose-chafer, Macrodactylus suhspinosus, has been less destructive than usual. My studies on this insect have appeared in bulletin form, and I need only emphasize here that all my tests of remedial measures were made in the field under ordin
