Argyrolepia quercifoliana, Fitch.—The Oak Leaf Tortrix. 
. ^ 0l a description of this insect and its work, see Miss Smith’s article 
in another part of this rej^ort. From a letter received from Dr. Board- 
man, before this goes to press, I learn that the estimates made by him 
in iegard to the damage done by this tortrix are fully confirmed. I 
learned recently that Prof. Fernald has identified this as Zeller’s 
Tortrix trifurculana , being a rediscription by Fitch. 
Penthinia vitivorana, Packard.—The Grape-berry Moth. 
When the grapes are nearly full grown they are sometimes attacked 
by a small white worm with a cinnamon colored head that eats a 
winding channel through the pulp. It continues to feed upon the 
pulp until lull grown, cr the inside of the grace has been consumed 
eating out the interior of the seeds as it comes to them. If one grape 
does not furnish sufficient food for it the caterpillar will eat into the 
second, fastening the second berry to the one whose interior has 
already been eaten out by silken threads. When full grown it leaves 
the grape and forms its cocoon on a leaf in a manner that seems pecu¬ 
liar to this insect, the method being thus described in the first volume 
of the American Entomologist. Alter covering a given spot with 
silk, the worm cuts out a clean oval flap, leaving it hinged on one side 
anc. rolhng this flap over, fastens 'it to the leaf, and thus forms for 
itself a cozy little house. * * Sometimes, however, it cuts two 
crescent shaped slits, and, rolling up the two pieces, fastens them in 
the middle. And frequently it rolls over a piece of the edge of the 
leaf, in the manner commonly adapted by leaf-rolling larva;, while we 
na,ve had them spin up in a silk handkerchief where they made no 
Within this retreat the worm changes to a chrsyalis, from which 
the moths emerge about the first of August. When full grown the 
worms are darker ihan when young, being either olive green or dark 
orown with a honey yellow head. The moths have the front part of 
the body lulvous, the hind wings and abdomen dark slate color The 
tore wings are “dark slate brown. From the middle of the costa pro¬ 
ceeds a blackish band, which curves to the middle of the outer third 
°* the wing ; beyond is a linear curved costal band, succeeded by an¬ 
other broader but quite short costal line ; the costa is tawny bevond 
sending a tawny patch obliquely inwards. Near the margin is an ir- 
regular blackish patch and two darker spots on the costa, and a larger 
one at the apex. It expands .40 of an inch.”—Packard. 5 
Remedies. It is probable that the second brood pass the winter in 
the cocoons, and by destroying the dry leaves in the fall, by burning 
will destroy many of the cocoons and lessen the number of worms for 
the succeeding year. The bunches of grapes that are infected may be
