Important cerambycid parasite determined.--In a recent examination 
of overwintering brood trees of the western pine beetle, Mr. Buckhorn 
found that the larvae of Acenthocinus spectabilis Lec., which are common 
under and in the bark, were underdeveloped and inactive, Many were putty ~ 
colored or light brown, Dissection of 46 larvae showed that 43 were 
parasitized by a large dipterous larva which had been reared from larvae 
and adults in the caging experiments of last year and identified by 
J. N. Aldrich as Arctiphyto gillettei Tns., related species of which are 
known to parasitize other longicorn beetles, 
Recovery of parasites in Weshington State.--P. B. Dowden, Melrose 
Highlands, reports that R. Latta and W. L. Baker, of the Sumner, Wash., 
laboratory, made several collections of satin moth material at the par- 
asite liberation point at Kent, Wash,, in April. These collections re- 
sulted in the recovery of two important European parasites, Apanteles 
solitarius Ratz. and Meteorus versicolor Wesm., which have been liber- 
ated there in the last few years, the material having been forwarded 
from the Melrose Highlands laboratory, Mr. Latta reported that Apanteles 
cocoons were fairly mumerous. Meteorus cocoons were very plentiful at 
Kent, every tree having a hundred or more hanging from the underside of 
the limbs. At Thomas (2 to 3 miles from the point of liberation) the 
cocoons were scattered but not hard to find, and at Auburn (6 to 7 miles 
from the point of liberation) one cocoon was found after careful examin- 
ation of four large trees, One hundred small satin moth larvae collecte* 
at Kent on April 3 were dissected at Melrose. Three of them were found 
to be parasitized by Apanteles and 3/7 by Meteorus. Apanteles solitarius 
Ratz. has been established in New England, where it is a very effective 
parasitc, but notwithstanding large liberations, Meteorus has never been 
recovered, The recovery of such numbers of Meteorus in Washington is, 
therefore, particularly gratifying. 
_ 2. B. Dowden reports on what appears to be the recovery of another 
hymenopterous parasite of the satin moth. Rogas unicolor Wesm., re- 
ceived from Hungary, was first liberated by the Melrose Highlands field 
laboratory in 1932. A Rogas larva was dissected in April from a hiber- 
nating satin moth caterpillar taken in Portland, Maine, where unicolor 
was put out in 1934, and there is little doubt that the Rogas larva 
found in dissecting the satin moth caterpillars belonged to this species. 
European pine shoot moth,~-All information from the entire infested 
region of the northeastern States and eastern Canada indicates that there 
has been a heavy recuction in European pine shoot moth larvae by winter 
killing. In most of Connecticut the mortality is about 90 percent with 
slightly less along Long Island Sound. In southern New York a projecte* 
control operation tas cancelled because of the heavy mortality, and a 
similar condition doubtless exists in western New York, Reports from 
Canada indicate a very heavy reduction. Tirough the activities of the 
CCC camps the work of direct control in Connecticut is »%eing increased 
and there is hope that the insect may be éxterinihated in nost arta’ of the 
State, except the very heavily infested area in the southwest corner.
