Saw-Flj on Fruit Trees. (Countrj GeDtleman, for November 12, 

 1885, L, p. 921 c. 3-4—25 cm.) 



In answer to an inquiry from Edinburg, Scotland, of some small, thin, nearly 

 transparent objects nearly half an inch long and looking like a leech, which for 

 several years had nearly destroyed the leaves of plum, pear, and cherry trees, 

 answer is made that it is the larva of some species of saw-fly, and probably of 

 Eriocampci adumbrata. Its ravages may be prevented by means of powdered 

 hellebore, to be obtained pure, and applied to the foliage by the hand or by 

 a bellows. Its efficacy is illustrated by an account of its use in the Hammond 

 Nurseries at Geneva, Ni Y. Directions are given for using the hellebore mixed 

 with water.
