a conference was held at Champlain, N. Y., with De. J. M. Swaine, L, S. | 
McLaine, and serveal assistants of the Canadian government, and with Dr. E. P, 
Felt and H, L. McIntyre of the State of New York, The infestation is estimated ¢ 
to contain about 1,000 egg clusters, The Canadian authorities will make a 
serious attempt during the coming winter and summer to exterminate the colony. 
The last of June puparia of Compsilura concinnata Meig. were sent to 
California in an attexpt to establish this parasite in that State. C. con- 
cinnata is one of the tachinida introduced from Europe as a parasite of the 
larvae of the gipsy and browm-tail moths. This species is not only well 
established in the gipsy moth area but has been recovered from native insects 
about 100 miles west of the gipsy moth quarantine line. Compsilura has a large 
number of native insect hosts and it is hoped that the species will become 
established in California, 
In October two colonies of Schedius’ kuvanae How. were-sent to Madrid, 
Spain, and one colony to Rabat, Morocco. At each of these places there is a 
heavy gipsy moth infestation. This egg parasite, which was-introduced into - 
New England from Japah, is now well established in the southern part of. the 
area of New England infested by the gipsy moth. Schedius has several genera--—— 
tions each year, and if it is established in Spain and Morocco it should 
become for those countries.a valuable parasite of the Zipsy moth egg.

In the month of October Dr. Brassica spent a few days at Asheville, 
N. C., discussing cooperative work with Messrs. Clapp and Frothingnam, of-the 
Forest Service, The necessity for ut ereeeee DS investigations. proceeding 
along with the Forest Service studies was fully recognized by all. Several 
large centers of southern pine beetle killings of 1923 were visited at the 
same time, It was found that tiis epidemic had completely died out, and no 
trees have been killed since the late summer of hh Fa 
On September 9, J.-C, Evenden made a final examination of the area 
covered by the sprayins operations instituted against ar sawfly and a needle 
tyer in the lodgepole pine stands at West Yellovstone, Yellowstone National 
Park, Mr. Evenden reports that the treated trees look very well and that all 
of the sawflies and from 75 to 90 per cent of the needle miners in the area 
sprayed were destroyed. It is firmly believed that had the spraying operation 
been completed two weeks earlier, vhich was absolutely impossible, a greater 
mortality of the needle tyers iss have resulted. At the time fo the spraying 
Operation many of the larvae had emerged from their needle mines and had 
constructed nests into which the spray did not Deere ae
