Gelechiidae 
in the -“First Missouri Report,” the accompanying cut has been 
taken. It shows a gall as it appears from the outside, and also a 
section of a gall, revealing the home which the larva constructed 
for itself in the enlargement of the stem. 
The moth is very common in many parts of the country, but 
particularly in western Pennsylvania. 
Genus ANARSIA Zeller 
(i) Anarsia lineatella Zeller. (The Peach-twig Borer.) 
Syn. pniniella Clemens. 
The insect which we are considering was in all probability intro¬ 
duced into California, where it is now most firmly established, from 
Asia, probably from Japan. 
The eggs are deposited at 
the point where the leaves 
are attached to the stems, 
or where the stem of the 
fruit is located. The larvae 
make minute burrows un¬ 
der the bark of the twigs 
and into the stem of the 
fruit, and thus cause dam¬ 
age both to the trees and to 
the peaches. The insect is 
double-brooded. The larvae 
are secretive, and hide so 
effectually that it is said to 
be very difficult to detect 
them. The insect remains 
in the pupal state about ten 
days, when the moth emerges. The imago is about half an inch 
in expanse of wing. The fore wings are of a beautiful gray 
color, clouded on the costa with darker markings. The insects 
of the second generation hibernate as larvae in their burrows in 
the bark of the twigs. 
A very full and excellent account of the habits of this 
insect has been published in the “ Bulletin of the United 
States Department of Agriculture ” by Mr. C. L. Marlatt. It is
