CURRANT PESTS 
rants and gooseberries, is by the four- 
lined leaf bug. The eggs of this insect 
are inserted into the twigs of bushes, par- 
ticularly currants. They are usually 
placed near the tips and protrude slightly 
through the bark. As they are white, they 
can be easily seen and, when once known, 
can be recognized again without difficulty. 
Much good may be done in controlling this 
insect by cutting off all egg-bearing twigs 
when pruning. The mature insect is a 
flat, bright green or yellow bug, with four 
black lines down the back and with the 
tips of the wings and two large round 
spots on the thorax also black. The 
nymphs or immature bugs occur with the 
adults near the tips of shoots and are ex- 
ceedingly active. These insects puncture 
the young leaves of currant and goose- 
berry bushes as well as of many other 
kinds of plants, causing brown _ spots 
which are sometimes so numerous and 
close together as to make the leaves 
wither. 
Remedy 
When, as is generally the case, only a 
few bushes are attacked, shaking off the 
nymphs and perfect insects into open pans 
containing water with a little coal oil on 
the top, is often sufficient. If the attack 
is more ‘extensive, spraying the bushes 
with kerosene emulsion or whale-oil soap 
solution will destroy all the _ insects 
reached by the spray. The winter is 
passed in the egg state, therefore, all egg- 
bearing twigs should be cut off and 
burnt.

General Appearance 
The adult females are clear-winged 
moths with delicate, slender bodies about 
three-eighths of an inch long and a wing 
expanse of from five-eighths to three- 
fourths of an inch. The general color is 
jet black with deep blue  iridescence. 
There is a yellow band around the base

of the head; three distinct and two indis- 
tinct yellow bands around the abdomen 
and two oblique longitudinal yellow 
stripes on the thorax. Because of sun- 
shine these lines and bands are mislead- 
ing in the photograph (Fig. 1) excepting 
the last two abdominal rings in the left- 
hand specimen. The areas on the thorax 
just below the wings are also yellow. The 
fore wings are opaque along the borders, 
with a small band enclosing a clear area 
near the opaque tips which are bronze. 
The hind wings are clear, excepting a 
brown border. The legs are banded yel-
