FOREST-INSECT INVESTIGATIONS 
F. C. Craighead, in Charge 
J. M. Miller made a field trip to the Prescott National For- 
est in November to check up the results of a control project which was 
conducted last winter and spring against an increasing infestation of 
Dendroctonus barberi Hopk. This is the first control project ever at- 
tempted against this species of Dendroctonus. The first year's results 
have been highly satisfactory, and it is recommended that the work he 
extended next year. 
W. H. Larrimer, in charge of the Division of Cereal and Forage 
Insect Investigations, and D. J. Caffrey, of the same division, visited 
the Gipsy Moth Laboratory on October 24. Other recent visitors to this 
laboratory were M. F. Crowell, of North East, Pa., on November 7; R. G. 
Smith, Inspector of the Plant Quarantine and Control Administration, 
stationed in New York City, on November 16; E. G. Woodward, Agent in 
Blister Rust Control, Warrensburg, N. Y., Raymond Paige, Fort Ann, N. 
Y., and W. S. Codman, Eldred, N. Y., on November 2l. 
C. W. Collins was in Washington November 21 to 23, conferring 
with members of the Bureau of Entomology, and especially with Dr. F. 
C. Craighead, in charge of the Division of Forest Insects, regarding the 
work of the Gipsy Moth Laboratory. Mr. Collins, while on this trip, 
stopped in New Jersey to confer with Dr. R. W. Glaser, of the Rockefeller 
Institute for Medical Research, and H. A. Ames, of the Plant Quarantine 
and Control Administration, regarding investigational work on the gipsy 
moth. 
Many entomologists are more or less unfamiliar with the pres- 
ent classification of the groups which comprise the termites or white 
ants. Frequently the family Termitidae is referred to in literature 
as an equivalent for the order Isoptera; formerly only one family, Ter- 
mitidae, was recognized, and most termites were referred to as species 
of Termes. At present the order Isoptera is separated into five families. 
Representatives of three of these families occur in the United States. 
Species in the genus Termes occur nowhere in the Americas. 
To refer to the genus Termopsis as being in the family Termit- 
idae is as great an error as to refer to a genus in the Buprestidae as 
belonging to the family Cerambycidae. To use the family Termitidae as 
equivalent to the order Isoptera may be regarded as the same as using 
the family Scolytidae for the entire order Coleoptera. 
Appended is a tabulation of the order Isoptera according to fami- 
lies, genera, subgenera, and species.
