Oregon. F. P. Keen (September 21 ): Some white fir twigs showing galls near 
Salem were determined by P. W. Mason as D. picoae . 
LARCH 
LARCH SAWFLY ( Lygaeonematus erichspnii Htg. ) 
General. G. E. Orr (September): Present in smaller numbers than has. been ob- 
served for at least 1'5 years in most tamarack stands in the Lake States. 
This is largely becaus'e of the extreme heat and drought early in July 193&. 
Young sawfly larvae were abundant early in the summer of 193&» ^ u t nearly 
all of them died before reaching maturity. In some areas it, has been al- 
most impossible to find larvae in 1937* although reports of some defolia- 
tion in parts of upper Michigan have been received. 
West Virginia. W. L. Maule (August 27)* Specimens of pupal cases were taken 
in connection with infestation of European larch on the Rothkugal Planta- 
tion, Monongahela National Forest. (Det. by R. A. Cushman. ) 
. . LOCUST- 
LOCUST LEAP MINER ( Chalepus dorsalis Thunb. ) 
Rhode Island. A. E. Stene (September 21): Abundant near Westerly and locust 
groves were defoliated by the end of. August. 
Virginia. H. E. Hamric (August 17) J They were found swarming over the locusts 
in Independence, Grayson County, and eating chlorophyl from the leaves to 
such an extent that the leaves were drying up, giving the leaves the appear- 
ance of having been bitten, by a heavy frost. The locusts,'. were attacked 
last year, but not to a harmful extent. This year they look as though 
they' will die. (Det. by H. S. Barber.) 
North Carolina. Z. P. Me tcalf (September 18): I have never seen this insect 
more widespread or more injurious than it has been this. year in the north- 
western part of the State. In large areas every loaf of ever;/- tree is 
completely riddled. There are occasional areas where the damage is not so 
extensive and a few isolated trees are not damaged. 
MAPLE ... 
GREEN-STRIPED MAPLE WORM ( Anisota rubicunda ?. ) 
Virginia. A. M. Woodside (September 20): Several young silver maples near 
Staunton have been defoliated for the third successive year, 
A GALL INSECT ( Dasyneura communis Pelt) . . 
New Hampshire. E. P. Pelt (September 22): Red maple leaves with the veins al- 
most entirely deformed by the maple gouty gall were received from Nashua, 
the infestation being extremely severe.
