to appear while the fruit is young and green, and as it ripens 
they increase in number. Frequently several of these discolored and 
shriveled berries will be fastened together by silken threads inter- 
mixed with the excrement of the larve and the sticky grape juice, 
the larva having passed from one to another. The appearance is not 
unlike that produced by black rot, and is often confused with the 
latter. As the larva becomes mature it changes to an olive-green or 
dark-brown color, and not only execavates the pulp, but burrows into 
the seeds of the grape. It is very active and is apt to wriggle out of 
the grape and escape. When full grown, the larva attains a length 
of about one-third of an inch, and, abandoning the grape, cuts out of 
a grape leaf a little flap,which it folds over and fastens with silk, 
forming a little oblong case, in which it changes to a chrysalis. The 
little slate-colored moth with reddish-brown markings on the fore- 
wings appears in ten or twelve days, drawing its chrysalis partly

after it and depositing eggs for an additional brood of larvee. The 
last brood of larvee remains in the leaf cases through the winter. 
The moths coming from these hibernating chrysalides appear in 
early spring, and the first brood of larvee lives on the leaves, tendrils, 
and blossoms, there being, of course, no grapes for them to infest. 
This insect was imported many years ago into this country from 
southern Europe, where, in Austria and Italy particularly, it is very 
injurious and has two or three near allies which affect grape leaves 
and fruit in the same way, but which, fortunately, have not, as yeu, 
been imported into this country, or if so, have not become numerous 
enough to be recognized. Our grape berry moth is widely distributed, 
occurring probably wherever the grape is grown to any extent, from 
Canada to Florida and westward to California. It attacks all varie- 
ties, but is especially destructive to grapes with tender skins and 
such as grow in compact bunches. The records of the Department
