The Asiatic beetle, Anomala orientalis Waterhouse, has caused considerable injury to lawns by the grubs eating the roots of grass, some being noticed in the fall of 1922. In each of the seasons of 1923,1924 and 1925, the injury had been observed but was not very conspicuous in 1925 until late summer. During August, September and October, there were many complaints and reports from an area of approximately one-fourth of a square mile in extent. The matter was again reported to the Bureau of Entomology and the Federal Horticultural Board, with a request that they send some one to look over the situation. Later Mr. L. B. Smith submitted a report recommending that an effort be made to eradicate this pest; for should it spread southward it might cause serious injury to various crops; that the entire area not covered by buildings or pavements, be treated with carbon disulphide next spring to kill the grubs. Plans are therefore being made to procure the necessary funds, and to carry out Mr. Smith's recommendations.

The mines of the Imported Birch Leaf-Miner were first noticed in Connecticut in 1923, and the following year the adult was reared and found to be a sawfly, Fenusa pumila Klug, from Europe. Observations made in 1925 show that there were three complete generations and a partial fourth. Eggs are laid in the tender terminal leaves, and hatch in about ten days. The larval period requires an average of 11 or 12 days, and the winter is probably passed in the pupa stage.

This insect is now distributed throughout southern New England, southeastern New York, and in Vermont as far north as the vicinity of Rutland. Apparently it prefers the gray birch, Betula populifolia, but also attacks the white or canoe birch and the European white birch, including the cut-leaf form. Most of the mines are on young sprouts or seedlings, though in a few cases they have been observed on larger trees.

On September 8, 1925, stems of Rosa rugosa were received from Darien exhibiting the peculiar swellings or galls such as have been figured by Weiss as occurring in New Jersey and caused by Agrilus viridis var. fagi Ratz., a species from Europe. On October 15, stems of Rosa hugonis were received from Norwalk with similar galls. Norwalk and Darien are adjoining towns. The adults have not been reared in Connecticut, but it is characteristic Agrilus work.
