1931, a letter and returned specimens received from C. F. W. Muesebeck by 
C. W. Collins, of the gipsy moth laboratory, Melrose Highlands, Mass., are 
of interest. Mr. Muesebeck took specimens of certain species to Washington 
for study. Two species, which in former reports of the laboratory were 
referred to by generic names only, have now been specifically determined. 
One, determined by Mr. Muesebeck, is Orgilus obscurator (Nees). The other 
was identified by Mr. Cushman as Cremastus interruptor Grav. Mr. Muesebeck 
states, in connection with QOrgilus obscurator, that a single specimen, 
reared from the European pine shoot moth taken at Newport, R. I., several 
years ago is, in his opinion, the same species, indicating that this parasite 
is already established in this country." 
J. A. Millar, Melrose, Highlands, Mass., submits the results of his 
collections and parasite rearings of the gipsy moth larvae and pupae. 
These collections of 100 each are made from designated areas in the New 
mngland States and totaled 7,079 larvae and 1,954 pupae. He summarized 
the results for the larvae in the following table, comparing 1930 with 1931.

C. H. Batchelder ard D. D. Questel, of the Eurovean corn borer labo- 
ratory, Arlington, Mass., report as follows: "During the pericd of Aug— 
ust flight, August 8 to September 4, 3,126 corn borer moths were caught in 
bait traps on the Berkley farm. Ninety-five experimental preparations 
were employed as baits, the most effective being a 15 per cent solution of 
medium—grade molasses fermented with yeast. The maximum catch on one 
night in one trap was 24 and the total catch in 75 traps in one night was 
291. During the period August 18 to 24 a total of 988 moths were taken, 
of which 60.7 per cent were females. More than 80 per cent of the females 
vere newly emerged and had not deposited eggs. Various preparations of 
molasses, malt, cane sugar, fruits, and corn were employed in this series 
of fermented products, as well as many biochemical materials. Moths were 
caught when traps were set up on marshes and on islands in the river where 
the nearest cornfield was at least a mile distant."
