C-PSAT BASIH/CATSPPILLAR (it alacosoma fragilis Stretch) 
3. Lockwood (August 30): The great basin caterpillar 
destroyed the foliage of ceanothus and to a lesser de- 
gree manzanita over whole hillsides on the southern 
slope of' Mount Shasta near Shasta City, during the lat- 
ter part of June. The worms were so thick that trains 
were sloped to a standstill on the grades because of 
the crushed bodies on the rails. This was overcome by 
The locomotives being equipped with steam jets to blow 
the worms from the rails in advance of the wheels. 
Strawberries and garden peas were devoured also. 
KSiiLOCK ( Ellooia fiscellaria C-uen. ) 
E« I, KcDaniel (September 12): For several years the 
hemlock iooper has been destroying trees in the resort 
region of Michigan. A recent survey mac'e by Mr. Korcf sky 
of this department sho'-'s that one plat cf 4S acres of 
forest land containing hemlock, pines, and hardwoods has 
been seriously attacked at Pentwa-ter. The hemlock is all 
dead or nearly so and the larvae -are feeding on the white, 
Austrian, Scotch, and jack pines, also on oak, alder, 
beech, and cherry. The only trees present that are not 
attacked ;re maples and locust. The hardwood is evident- 
ly being eaten because of the killing of the hemlock and 
pines. At the time cf . the survev (September 5). very few 
larvae and pu:ae were present, but many adults were .to 
be found. 
SAT Ik MOTH ( Stil nnotia s alicis L. ) 
Hew- Hampshire ~. C. Craighead (September 13): On August 22, C S. 
Hood and J. E. P.. Eolbrook of the gipsy moth laboratory 
noted feeding by the young larvae on the foliage of large 
trees of the large- toothed aspen, ? o tu I us zx ar.di de n tatg 
Mich. , growing under woodland conditions in Kingston. 
Feeding had been so severe in one small area that the 
brown skeletonized foliage was noticeable from a consid- 
erable distance and here the hibernation webs were very 
abundant in crevices in the bark. This is the first 
record the gipsy moth laboratory has of a satin moth in- 
festation occurring in a woodland area in Pew England.
