Accompanied by entomologists of the States concerned, Dr. M. T. 
Smulyan, of the gipsy moth laboratory, took a trip through southeast— 
ern New Hampshire and southwestern Maine during the latter part of June 
and early July to determine the extent of the brown-—tail moth infesta-— 
tion. It is in this area that most of the injury by this species has 
taken place during recent years. Dr. Smulyan states that the infesta- 
tion this year was much lighter in New Hampshire than it was last year. 
In Maine it was somewhat lighter than last year, though in the more heavily 
infested area it was slightly heavier. Dr. Smulyan also made observations 
of the brown-tail moth fungus (Entomophthora aulicae Reich.). 
The last shipment of tachinid parasites of the gipsy moth to 
reach the gipsy moth laboratory from Europe this year arrived on July 17. 
Approximately 170,000 puparia were received. Of these about 150,000 
were Phorocera agilis R. D., which has so far been recovered only from 
the vicinity of colony sites in Boxford, Mass. It was put out in Box- 
ford in 1927 and 1928, and a few puparia have since been obtained each 
year from collections of gipsy moth caterpillars made in that town. 
During the month of July shipments of puparia of Compsilura con- 
cinnata Meig., were sent to Barbados, B. W. I., and to the State of Wash— 
ington, from the gipsy moth laboratory. It is being sent to Barbados 
with the idea that it may establish itself there as an enemy of army- 
worms and cutworms, and in the State of Washington it will be liberated 
in a satin moth infestation. Adults of Eupteromalus nidulans (Thom.) 
were also sent to the State of Washington for liberation in an area where 
the satin moth occurs. 
Liberations of two species of parasites of the European pine 
‘shoot moth, received from Austria, were made by the gipsy moth labora~ 
tory in July. One species belongs to the genus Orgilus (Braconidae), 
and the other has been identified as Cremastus interruptor Grav. (Ich- 
neumonidas), which was successfully introduced into Canada from England 
in 1928. Colonies of the latter species were put out in Brookline and 
Hingham, Mass., while the Orgilus adults were liberated in Brookline. 
A small liberation of a species of Phanomeris (Braconidae) was 
made in an infestation of Phyllotoma nemorata Fall., at North Conway, 
N. H., in July. Small numbers of two other parasites of this imported 
leaf-mining sawfly on birch had already been colonized by the gipsy moth 
laboratory this year. The three parasites were received from Austria. 
Last March collections o1 cocoons of the oriental moth (Cnido- 
campa flavescens Walk.) were made at 135 points in and near Boston, Mass. 
where adults of Chaetexorista javana B. & B., issuing from material re-— 
ceived from Japan, were liberated in 1929 and 1930. By the end of July 
adults of the tachinid fly had issued from 12 of the 15 collections. 
Two of the 13 collections came from the vicinity of 1929 colonization 
points, and the remainder from areas where liberations were made in 1930.
