Abstract
The southern pine beetle has appeared in the southern part of Pennsylvania, and during the winter of 1932-33, many areas of infestation were located in Franklin, Fulton and Bedford Counties. Although the northern range of the insect is recorded as extending across the southern part of the State, records of its capture are few and serious outbreaks up to the present time are practically unknown.
