BIRCH LEAF-SKELETONIZER (Bugcuietrix e anadensisella rharrb.) 
New Hampshire P. R. Lowry (September ll): Many birches are being skeletonized 
in Durham. Pupation has just begun. This insect is prevalent 
over the southern half of the State, but no information has been 
received as to the conditions in the northern half. 
Massachusetts A. I« Bourne (September 25): In coming across the State a short. 
time ago, I found that in practically all of the northeastern sec- 
tions, the birches were completely browned as a result of the feed- 
ing of these insects. Driving along the roads, I noticed every 
tree, ever, isolated trees, here ana there in pastures, browned as 
if scorched by fire. Practically no green tissues were left to 
the foliage. Much of the same condition pre '/ailed here in the 
Connecticut Valley, although the injury is rot quite as severe as 
in the northeastern section cf the State. It was interesting to 
note, in the higher levels around Athol, ©ardner, etc., in northern 
Y.'crcester County, that the injury was markedly less than in the 
lower areas iirmed iat sly to the east a :. "est. It .vas also striking 
that throughout Eerkshire County much the seme thing held true; the 
birches in that section, in the region around Pittsfield, Dalton, 
and Lenox, etc., showed very little evidence of the ravages of the 
skeletonivser . 
Connecticut W. E. Brixton (Septemoer -°4): Reported as being all over the State. 
About the sa^e as last year.

all comiiiOn eatalpa trees on ray farm at Avanel. 
Ohio H. A. Gcssard (September 18): Rep c res of damage by the cataloa 
sphinx continue tc arrive. On August 21 specimens came from 
Lynchburg, arc on September 10 from Barnesville. 
Indiana J.J. Davis (September 18): The 3 at alp a sphinx caterpillar has 
been common and destructive in the southern two-thirds of the State, 
more so in the southern third. 
Illinois F, H. Benjamin (August 20); A tree in the City of Decatur, Macon 
County, practically defoliated. About 40 per cent of the larvae 
heavily parasitized by' braconids.
