them, the shrivelled remains of the worm from which these par¬ 
asites came gave indications of its having been a Lepidopterous 
rather than a Coleopterous larva. Five of these parasitic worms 
had come from it, but of this number three were so weak and 
immature that they died without forming their cocoons. 
We have only to state in conclusion, that the utter carelessness 
with which the currant is treated in most of our gardens, with a 
thicket of young shoots annually left unpruned and crowding upon 
and smothering each other, gives these borers and other pernicious 
insects the utmost facilities for lurking unmolested and pursu¬ 
ing their devastating work without interruption. Were this shrub 
suitably trimmed and kept thinned out to only three or four stalks 
from each root these stalks growing freely exposed to the light 
and air would be little if any infested by these depredating 
insects. 
As these worms remain in the dead stalks through the winter 
their destruction is easily effected. By breaking off all the dead 
brittle stalks at the surface of the ground and burning them these 
borers may at once be exterminated from the garden. But they 
.will soon find their way back again unless the bushes are well 
pruned every year.

tcra. Trochiliiilse.) 
Feeding upon the pith of currant stalks causing them to 
perish, a small whitish worm witlx a darker line along the middle 
of its back and a brown head and legs; changing to a pupa with¬ 
in the stalks, and the fore part of June giving out the perfect 
insect, which is a small moth having some resemblance to a wasp, 
its wings being clear and glassy, the fore pair opake yellowish at 
their tips, with a black margin and band near the middle, and the 
abdomen black with three yellow bands situated one upon each 
alternate segment. Width 0.fi5 to 0.85. 
This insect, to which the common names of Currant hawk- 
moth and Currant clear-wing are given in English works will be 
more readily known in this country by the name which we have 
appended to it. A short history of it is given in Dr. Harris’s 
Treatise, p. 255, under the name JEgeria Tipuliformis. The reason
