and almost immediately destroyed by the use of carbolate

and perfectly safe. The method of using it is to sprinkle it 
over the bushes as soon as the worm makes its appearance, 
bringing it well in contact with the leaves, and soon the 
insect is destroyed. It will need but two or three applica¬ 
tions, and the work is done.” 
This worm attacks the gooseberry as well as the currant,

farther spread, in buying or transporting gooseberry and

of it is extracted from my “ Guide to the Study of Insects.” 
This saw fly (Fig. 37 a, larva; 6, female, from the “Amer¬ 
ican Entomologist;” P. grossularice of Walsh) “is a widely 
diffused species in the northern and western states, and 
injures the currant and gooseberry. The female fly is shin¬ 
ing black, while the head is dull yellow, and the legs are
