In the neighbor- ing city of Buffalo, it has become a scourge, defoliating the horse-chestnut trees, and attacking other trees as veil. To gather and destroy the cocoons or egg masses in winter seems to be the most feasible method of checking the ravages of this insect. The birch trees in the parks are attacked by a new pest, an Agrilus. The species will be determined next summer. Crioceris asparagi, Linn., the Asparagus Beetle, (Fig

S. Packard, is not a native but an introduced spacies has advanced in its attack upon asparagus plants as far north as Niagara River. Mr. Reinecke informs me that he has found the beetles in abund- ance on asparagus at Buffalo. The Punctured Clover-leaf Weevil, Phgtonomus punctatus, Fabr., in August last, appeared in great numbers on the side-walks and fences and on the shores of Lake Erie, but though I have repeatedly examined the clover fields for the purpose of deter- mining the amount of injury done by this particular insect, thus far I have failed to find either the imago.

In submitting my report as director for Division No, 5 for 1898, I am very glad to state that there have bean no additions to the number of injurious insects in this district, with two exceptions ; in fact there has been a falling off in numbers of older pests that in previous years played great havoc with certain crop3. One exception is the Cottony Maple scale (Pulvinaria innumerabilis, Rath von)— Fig. 59—which appeared in very large numbers this last spring; in fact, in such large numbers did they appear that on one of the finest streets in this city (London), the trees appeared to have been sprayed with white- wash.
