protect citizens from ignorant or fraudulent commercial operators in 
the control of these insects. All operators now doing commercial work 
in termite control in eight of the southern counties of California are 
required to pass an examination on their ability, and, after examina- 
tion by county officials, to present a certificate showing that they 
are qualified. Considerable work is being done by the Termite Investi- 
gations Committee in fundamental studies of the distribution, biology, 
and control of termites. 
Contributions from the Gipsy—Moth Laboratory 
Recoveries of two tachinid parasites of the gipsy moth, made dur- 
ing the summer of 1929, indicate for the first time that these species 
have become established in New England. One of them, Sturmia inconspic- 
ua Meig., besides being a parasite of the gipsy moth in Europe, attacks 
a number of sawflies, including Diprion simile Hartig, which is now 
Meewent in certain of the Northeastern States. The other, Phorocera 
agilis R. D., is one of the most important insect enemies of the gipsy 
moth in Europe. Shipments of Sturmia inconspicua were received at the 
Gipsy-Moth Laboratory as early as 1906, and Phorocera agilis was first 
received in 1907. Especially during the past five years rather large num- 
bers of adults of both species have been colonized. 
C. F. W. Muesebeck, of the Gipsy—Moth Laboratory, was in Maine 
September 26 to 28, where, in company with H. B. Peirson, Forest Ento- 
mologist of that State, he saw some of the investigational work that Mr. 
Peirson is carrying on with a birch leaf-mining sawfly, Phyllotoma nemo— 
rata Fall. Extremely heavy infestations by this foreign pest were first 
reported from Maine by Mr. Peirson in 1927. Reports received at the 
Gipsy—Moth Laboratory in September indicated that it was very abundant 
in the White Mountain section of New Hampshire and in the vicinity of 
Marlboro, Vt. The species was also reported from certain other sections 
of New Hampshire, Vermont, and Massachusetts. 

Among recent visitors at the Gipsy-Moth Laboratory were Dr. W. V. 
Balduf, University of Illinois, September 7; and John Hadjinicolaon, 
Athens, Greece, and D. W. Jones, of the Corn-Borer Laboratory, Arlington, 
Mass., September 18. 
W. L. Baker, who graduated from the Clemson Agricultural College in 
1927, and who has since then taken postgraduate work at the University of 
Minnesota, was given a probationary appointment as Junior Entomologist, 
on September 16, reporting for work at the Gipsy-Moth Laboratory. 
T. H. Jones and C. F. W. Muesebsck, of the Gipsy—Moth Laboratory, 
visited the Bartlett Tree Research Laboratories at Stamford, Conn., on 
September 23.
