hemlock LOO PER 
The revere and widespread outbreak of Ellopia f iscellaria lugubrosa Hulst. 
that appeared in the fir stands of northern Idaho and western Montana in 1937 
continued during 193 S, although in some of the most heavily defoliated areas there 
was a decrease in the amount of feeding this season. Many tree species besides 
the preferred true firs were attacked, and in some areas the upper limits of white 
pine stands were severely injured. Near Darrington, Wash., adults were noted in 
flight in unusual numbers, but no defoliation was observed. The last outbreak 
in this locality in Washington occurred .-bout 10 years ago. (Division of Forest 
Insect Investigations, Bureau of Entomology and Plant Quarantine, U. S. D. A.) 
DOUGLAS EIR TUSSOCK MOTH 
The outbreak that has been present in the Sawtooth National Forest, Idaho, 
for the last 2 years continued at approximately the same severity in 1938. Work- 
ing in association with this insect is a looper identified as Nepytia canosaria 
Walk, var., and these two insects have caused a complete destruction of all 
Douglas fir in the defoliated area. In the Blue' Mountains of Oregon the tussock 
moth extensively defoliated white fir and Douglas fir, and as a result some of 
the timber will die. (Division of Forest Insect Investigations, Bureau of Ento- 
mology and Plant Quarantine, U. S. D. A. ) 
LARCH SAWFLY 
In the northern part of the Lake States the larch sawfly appears to be on 
the increase, although it is not abundant. In northern Montana the outbreak 
occurring on the north fork of the Flathead River during the last several years 
continued at about the same severity -as in 1937 , without doing serious damage. 
A new infested area was reported on the middle fork of the Flathead River, in 
Glacier National Park, but the sawfly is not in epidemic form in this area.

WO LARCH SAWFLES 
The two larch sawflies, Platycampus laricis Roh. and Midd., and P. lari- 
civorus Roh. and Midd., were reported in northern Idaho some 20 miles north of 
Coeur d’Alene. This is the first outbreak of these two species that has been 
recorded since their first known appearance in 1921. (J. C. Evenden, Bureau of 
Entomology and Plant Quarantine, U. S. D. A.) 
EUROPEAN SPRUCE SAWFLY 
Surveys of spruce areas, in cooperation with the States of New Hampshire, 
New York, and Vermont, in 1938 showed that this insect was present in at least 
small numbers wherever spruce was examined. In New Hampshire very heavy in- 
festations occur on Mt. Monadnock, and on Pack Monadnock and Temple Mountains 
near the Peterboro-Temple town line, also a medium- to— heavy infestation occurs 
near Mt. Kent, in the town of Pittsburgh, in the northern part of the State. In 
Vermont the infestation is very heavy in the towns of Wilmington and Marlboro, in 
the southern part of the State, medium to heavy on Green Peak, in Dorset Township,
