I. HcDaniel (September 12): An infestation of about 
80 acres near Shelby v- a s reported in 1928. The infesta- 
tion is spreading quite rapidly and now involves an area 
about 1? miles long including between 2 , CCD and 2 , 500 
acres. Larvae this year stripped the beech trees and 
attacked also some of the oaks. Ho damage rr as done to.

T. H. Jones (September 20): from letter from Mr. 
Mueseoeck: -! Hr. Snaffner and I spent til? period Septem- 
ber 11 - 14 in an attempt to obtain some further inform- 
ation on the distribution of the introduced birch leaf - 
mining sa-'fly. Our observations ■■•ere restricted to He™ 
Hampshire and Vermont in addition to a few points in 
northeastern Massachusetts . 7e followed a route along 
the eastern border of Hew Hampshire northward through 
Ossip:o. and Horth Coivay to C-orha.m, from there -•est- 
v-ard to Lancaster, 17. P., and St. Johnsbury, Vt. , then 
southward through Bar re and Rutland to Pennington, Vt. , 
in the extreme southwestern part of the State, and from 
Bennington castas rd through Prattieboro, Vt. , Pdchmord 
and Pirdgs, P. P., and As hour nha.m and r-roton, Pass., to 
Helrosc. "rchi this it will be apparent that • consider- 
able section of the 'P.ite Haunt air. district of He™ Hamp- 
shire, a large part of Vermont, and a sm-li district in 
southern Hew Hampshire were covered, in addition to a. 
few points in Massachusetts. Because of the supposed 
preference of the insect for white birch, we scouted 
particularly areas -here this species is more or less 
common, but in these districts other species of bircn 
were also examined. G-r?y birch seemed to us to be al- 
most as favorable a food plant as white birch, and lar- 
vae were also, found in small numbers mining the leaves 
of yellow birch. Prom our hurried observations it ap- 
pears that it is more abundant in the north and in areas 
of considerable elevation. At any rate, the heaviest 
infestations noted were on the hillsides in the ""kite 
Mountain region of 2"e™ Hampshire. Only one moderately 
heavy infestation was found well to the southward at 
Marlboro, Vt. , and this on a hilltop at some elevation. 
This species was, however, found in small numbers z t
