GRAPE. CURRANT. 
anastamosing in every direction. The central dusky brown spot is placed upon 
the inner side of the double rib-vein, and commonly there is a more faint spot 
forward of this, which on its inner side is confluent with a slight cloudiness of 
the same color which extends from the central spots forward along the middle 
of the back to the base. Often also a third spot, much smaller, may bo dis¬ 
cerned in the second or third cell back of the central spot. The ovipositor is 
ns long as the abdomen and perfectly straight; its sides are dark brown and its 
end black. The two appendages at its base are much shorter than in the other 
species, being scarcely half the length of the ovipositor. The feelers are sensi¬ 
bly shorter and thicker than in the other species, their penultimate joint hav¬ 
ing the form of a reversed cone, its length scarcely double its width and less 
than half the length of the last joint, which is thicker than those which pre¬ 
cede it, and on its inner side is very plainly cut off in a sloping direction from 
the middle to the tip, with the face of this slope deeply excavated and causing 
the joint'to appear like a hollow tube. The antenna are blackish on their 
upper side towards the base, or have a black ring at the tip of each joint. 
10. THE CURRANT .—Ribes rubrum. 
We place this shrub and the gooseberry in this connection, as 
their woody stalks and the form and texture of their fruit give 
them such a close relationship to the grape; though they might 
with perhaps equal propriety be classed with the raspberry, straw 
berry and other small fruits of the kitchen garden. 
AFFECTING THE STALKS. 
134 . American currant borer, Psenocerus supernotatus, Say. (Colcop 
tera. Cerambycidae.) [Plate ii, fig. 1.] 
Feeding upon the pith of the currant and killing the stalks, a 
small cylindrical white worm wholly destitute of feet and with a 
small chestnut brown head and black jaws; passing its pupa state 
in the stalks and the latter part of May changing to a small slen¬ 
der long-horned beetle of a black color edged with chestnut brown, 
its wing covers each with two small gray spots forward of their 
middle and a white crescent-shaped one towards their tips. 
In all our gardens numbers of the currant stalks perish every 
season. To such an extent does this mortality prevail that this 
fruit would soon disappear from our country were it not that the. 
roots of this shrub are so vigorous, sending up a multitude of new
