J. M. Miller and J. C. Evenden visited our field station at Ashe=

J. A. Beal and Dr. F. C. Craighead spent the third week in March 
at the branch at Starke, Fla., of the Southern Forest Experiment Station

The Department of Natural Resources of the State of California has 
just issued as Bulletin No. 7 “Insect enemies of California pines and 
their control," by F. P. Keen, Associate Entomologist of the Bureau of 
Entomology. This bulletin deals in a comprehensive way with the most 
important forest insects of California, and will be of considerable use 
to foresters and lumbermen interested in protection from such insects. 
On March 22 and 235 the Fourth Shade Tree Conference was held in 
Washington. The Conference is a meeting of scientists and persons en- 
gaged in practical shade-tree work, held to discuss the improvement of 
conditions in general as regards the shade trees of the United States. 
Dr. ©. L. Marlatt spoke on work of the Bureau of Entomology and its re- 
lation to shade-tree problems. A round-table discussion on injury by oil 
sprays and the use of casein spreaders was led by Dr. W. E. Britton, 
Connecticut State Entomologist, and a paper on "Some factors affecting 
outbreaks of shade-tree insects" was given by William Middleton, of 
this office. The following entomologists were in attendance: Dr. C. L. 
Marlatt, Chief of the Bureau of Entomology, Dr. E. P. Felt, Chairman of 
this conference, Dr. W. &. Britton, Prof. J. S. Houser; of Ohio, A. F. 
Burgess, W. 0. Hollister, of The Davey Company, and Mr. Middleton. The 
meetings were very well attended and there were some interesting and pro— 
fitable discussions. 
Dr. T. E. Snyder reports that interceptions of the dry-wood termite 
Kalotermes (Cryptotermes) piceatus Sny. in 1927 at the port of Honolulu, 
Hawaii, probably establish China as its original habitat, termites of this 
species having been discovered in household articles of Chinese passengers 
from China. This termite has been known to occur in the Hawaiian Islands 
only since 1904. It is found at Honolulu (on Oahu) and at Hilo (on Hawaii).
