WHIT^-MAEKED. TUS3CC? MOTE 
Early in the spring there were indications, from the number of egg 
masses, that the white-marked tussock moth ( Hemerocampa leucosti<p-aa S. 
& A. ) would be somewhat more abundant than usual in New England. Later 
in the season larvae were quite numerous in the Middle Atlantic States. 
The first brood developed to rather serious numbers in the East Central 
States, but this brood was heavily parasitised and the second brood was 
of minor importance. 
FIR TUSSOCK MOTH 
The fir tussock moth ( Hemerocamoa pseudotsugata McD.), which suddenly 
appeared about three years ago as a new defoliator, as far as our 
experience is concerned, continues to spread and appear in new areas, 
although in some of the first outbreaks reported a marked redaction du© 
to parasitism and starvation is apparent. A forest ranger has advanced 
the theory that this caterpillar is locally transported by sheep and 
cattle passing through the infested areas. The female moth is wingless. 
The principal centers of infestation at the present time are at Jarbridge, 
Nev. ; on the Weiser and Idaho National Forests, Idaho; and near Northport, 
Wash. 
bagworl: 
During the winter and early spring the bags of the bagworm ( Thyridop. 
teryx ephemeraeformis Haw.) were quite numerous in the Middle Atlantic, 
East Central, and West Central States. Scattered reports were also 
received from the lower Mississippi Valley. As the season advanced, 
considerable damage was reported from many places in Mississippi and 
also from the Middle Atlantic States south?,'ard to South Carolina, and 
conditions in the East Central States westward to Kansas became 
increasingly serious. 
GYPSY MOTH 
"The gypsy moth ( Porthetria dispar L» ) extermination project in 
New Jersey has been continued by the New Jersey State Department of 
Agriculture and the Plant Quarantine and Control Administration of the 
Federal Government. The intensity and size of the original infestation 
have been greatly reduced. Since the start of this work over 2,000 
square miles have been thoroughly examined and whenever necessary 
extermination treatments have been applied. At the present time less 
than 140 square miles remain to be intensively scouted and the annual 
expenditure is gradually decreasing. 
" The gypsy moth situation in the barrier zone is not as gratifying 
as in New Jersey. The spread of this insect has been stopped since 
the establishment of the zone in 1923. As a result of the intensive work 
carried on by the New York State Conservation Department and the Federal
