Kast, Pa., where he will resume his duties in connection with grape-insect investigations. 
Mr. R. A. Cushman, who has been spending the winter months in the National Museum,

FOREST INSECT INVESTIGATIONS. 
A. D. Horxiys, In Charge. 
Mr. Joseph J. De Gryse was appointed field assistant, March 1, and assigned to work at 
the Falls Church, Va., station. He is assisting Mr. Heinrich in forest Lepidoptera. 
On May 12, Dr. Hopkins returned from a two wecks’ stay at Kanawha Station, W. Va., 
where he was making observations on experiments with cedar for rustic work to avoid attack 
by insects, seasonal history, studies of insects in prepared trap trees and conducting phenological 
investigations. : 
On May 8, Mr. Carl Heinrich left for a 10-day trip to Long Island, N. Y., and Guys Mills, 
Pa., to secure rearing material of Hvetria buoliana and to study cankerworm conditions. 
Mr. Craighead and Dr. Béving returned at the end of April after a week’s trip to Tyrone, Pa., 
spent in the investigation of depredations by, and control of the poplar borer (Saperda calcarata). 
Recently Dr. W. E. Britton, State entomologist, Connecticut, has forwarded to the Bureau 
of Entomology specimens of larve and adults, determined by Mr. S. A. Rohwer of the branch 
of forest insects, as the European Diprion similis, which has been found established in a nursery 
at Elm City, Conn. How long this insect has been in this country or how well established is 
at present unknown, but from the evidence submitted by Dr. Britton is seems to be thoroughly 
established in the nursery mentioned. This insect, which, in Europe, is a serious enemy to 
coniferous trees, lays its eggs within the needles of the pine. The larve have black heads, 
black legs, and a greenish body which is marked with a number of black spots. 
In connection with the Eastern Station at East Falls Church, Va., there has been established 
a nursery which contains a number of species of conifers and a number of species of oak. The 
purpose of the establishment of this nursery is to have immediately available small trees on 
which to conduct experiments dealing with oviposition, incubation periods, feeding of young — 
larve, formation of galls, and the possibility of alternation of hosts of various forest tree insects. 
The Forest Service has supplied coniferous transplants in 100 lots of 21 different species, rep- 
resenting the following five genera: Picea (3 species); Pinus (12 species); Abies (3 species); 
Larix (2 species); Pseudotsuga (1 species). The oaks, which were secured by purchase, consist 
of 2 to 3 feet transplants of 10 individuals of each of the following species: Quercus alba, 
Q. bicolor, Q. coccinea, Q. macrocarpa, Q. velutina, Q. rubra, and Q. palustris. 
The investigation of insects affecting shade trees and hardy ornamental shrubs has been 
te) . 
assigned by the Chief of the Bureau of Entomology to this branch.
