The female presents the following varieties: 
a. A slender transverse black line in the middle of the orange band upon the suture 
between the fourth and fifth segments of the abdomen. Common. 
b. The o.ter edge of the hind wings with a slender straw yellow Etiipe its whole 
length. 
c. No vestiges of a straw colored stripe on the outer edge of the hind wings.; 
d. The space between the two inner veins of the hind wings nearly or quite covered 
with blue-black scales, forming a stripe which divides the transparent disk into two 
parts. Quite common. 
Various remedies have been proposed for protecting the peach 
trees from this pernicious insect, by the numerous writers who 
have treated upon this subject in our agricultural and horticul¬ 
tural publications, such as raising a mound of earth around the 
tree and removing it during the winter season; pouring boiling 
water around the root; placing around it a bed of cinders, of 
ashes, of lime, &c.; surrounding it with a collar of mortar; en¬ 
veloping the root and base of the trunk in matting or in paper. 
There is much testimony showing that several of these measures 
are, singly, a sufficient safeguard. Recently an article has been 
going the rounds of the papers, stating that tanzy set out around 
peach and other fruit trees would protect them against this and 
other insects. Attention was said to be diiected to this remedy 
from the fact of a large peach tree, upwards of forty years old, 
being noticed as having a bed of tanzy growing around its trunk, 
and the account states that upon setting out this herb around 
several trees it grew thriftily, and it appeared that whilst sound 
trees were preserved by it, unsound ones were renovated. Al¬ 
though some editors have expressed themselves as skeptical with 
regard to the efficacy of this measure, I am inclined to think it 
merits a trial. That this herb is repulsive to insects generally I 
infer from the fact, that on sweeping it for insects only a very few 
can be obtained, when a similarly dense growth of other weeds is 
certain of yielding to the collector quite a variety. This at least 
has been my own experience. One of my correspondents, how¬ 
ever, thinks he has captured insects as abundantly from this as 
from other weeds. 
The hollow cavity extending down the side of the root of the 
peach tree, which is formed by the peach borer, does not become
