Southeastem States. The "birch leaf miner (Fgimsa punaila Klug) again seriously 
damaged the foliage of birches in southern New York and Connecticut. The 
hemlock spanworm ( ELlopia fiscellaria C-uen. ) is still seriously infesting hemlock 
and balsam fir in Wisconsin. 
On the Beaverhead- Bit terroot National Forests in Montana there exists one 
of the largest epidemics of the mountain pine beetle ( Dendroctonu3 monticola 
Hopk, ) that has ever been recorded. This epidemic has been going on almost 
continuously since 1909 but until very recently it has been in unmerchantable 
timber, 
A serious outbreak of the Black Hills beetle ( Dendroc tonus nonderosae Hopk.) 
has suddenly come into prominence in the Colorado national Forest, Colo, Approxi- 
mately 250 square miles are involved. Last year the infestation increased 500 
per cent. The epidemic of this beetle in the Kaibab National Forest, Ariz,, 
has completely subsided. 
In southern Oregon in the vicinity of Klamath Lakes the western pine 
beetle ( pendroc tonu s breyicoiois Lee*) has again increased in prominence. Private 
companies are undertaking control during the present winter and spring. 
Brood XVII of the periodical cicada ( Tibicina sept end ecim L#) is one of the 
problematical broods with but few well-developed colonies reported. It has 
been reported from Virginia, Georgia, Iowa, Missouri, and New York, but none 
of the records have ever been confirmed. In 1926 authentically determined 
specimens were taken from Doniphan County, Kans. ,about 100 miles north of the 
nearest previously recorded locality for this brood, in Cass County, Mo. This 
was the only record of the appearance of this insect in 1926, 
INSECTS AFFECTING DOMESTIC ANIMALS 
A srery severe outbreak of the stable fly ( Stomoxys calci trans L.) , believed 
to have been the most severe since the unprededented conditions of 1912, occurred 
throughout the grain belt of northern Texas and southern Oklahoma. During its 
height dairymen reported a reduction of milk flow of from 5 to 50 per ce&t, farm 
work ^as discontinued, and meat animals were rushed to market on account of 
loss of weight. As was the case in the earlier severe outbreak mentioned, a 
large grain crop, with the production of a surplus of straw, followed by wet 
weather, brought about conditions very favorable for the breeding of flies in 
straw stacks. 
MISCELLANEOUS PESTS 
The number of reports being received by the Insect Pest Survey of damage 
done to buildings and other woodwork by termites has increased every year since 
the Survey started. This is possibly owing to an increased interest in the 
damage done by these pests. 
Among the newer pests that have come to our attention during the year 
i3 one of prunes, a small moth (Mineola £cvtulella Dyar) reported from Idah*. 
The scale insect JLecaniim corvlii L* haa occurred in very serious numbers 
in the western part of the State of Washington, as has also the satin moth
