emergence showed increases in weight. It is also noted that in closed 
containers in which puparia are held the moistened blotting paper dries 
out rapidly as the flies emerge. This tendency on the part of nearly 
developed puparia to absorb water may facilitate the emergence operation, 
as the bursting of the puparium is dependent on the localization of body 
fluids in the ptilinun." 
Effect of low temperature on cane-berry mites.~-Reporting on the 
Eriophyes of cane berries, particularly Eriophyes essigi Hassan, Joseph 
Wilcox, Puyallup, Wash., states: "From December 6 to 15, temperature 
dropped below freezing each day, on the 10th and llth was down to about 
10° F., and on the 14th when loganberry leaves were examined Eriophyes 
were still present on the leaf surface, showing that these mites do not 
always reach the buds for hibernation before winter weather arrives. In 
none of the buds examined * * * was there any evidence of injury to the 
mites from the low temperatures. Dead mites, or rather the empty skins, 
were abundant in some buds infested with predacious mites, probably Seius 
pomi Parrott; two other species of mites were commonly observed in the 
buds and often closely assotiated with the Eriophyes, but no evidence 
was obtained that they were predacious. Eriophyid eggs were found in 
buds of the undetermined variety of blackberry collected on December 29 
in Seattle, but in no other buds. A thornless variety of blackberry grow-— 
ing in close proximity to the other did not have a single mite; all the 
buds on the thornless variety were dead, apparently from the low temper-— 
ature, and it is possible the mites had deserted it after the injury; and 
no evidence of damage was noted in the buds of the other blackberry."

Parasite work at Melrose Highlands, Mass.--summary.--J.A. Millar 
has completed the examination of 369,100 eggs from 766 gipsy moth egg 
clusters collected last fall in 37 towns in New England. He found that 
51,672 eggs, or 14.0 per cent, were parasitized by Anastatus disparis 
Ruschke and 4,856 eggs, or 1.3 per cent, by Qoencyrtus kuvanae How. 
Mr. Millar and R. Wooldridge have completed summarizing the re- 
sults of the 1932 study of the parasitization of gipsy moth larvae, this 
work being based on two sample collections in each of 37 towns in the 
infested New England area~~a total of 7,838 larvae. The percentages of 
larvae killed by various species of parasites are as follows: By Apanteles 
melanoscelus Ratz.; 0.6 per cent; by Compsilura concinnata Meig., 13.4 
per cent; by Hyposotor disparis Vier., 0.1 per cent; by Sturmia scutellata 
R. D., 0.4 per cent; by unknown tachinids, 0.1 per cent; total larval 
parasitization, 14.6 per cent. 
T. H. Jones has compiled the results obtained in 1932 from dissec— 
tions (by H. A. Bess and H. C. Hyson) of iarge brown-tail moth larvae | 
for parasite records. A total of 1,254 larvae were collected in 16 
towns in New England. The parasitization was as follows: By Compsilura 
Soncinnata, 11.2 per cent; by Sturmia nidicola Towns., 7.7 per cent; 
‘by Meteorus versicolor Wesm., 3.1 per cent; by unknown parasites, 0.6 
per cent; total, 22.0 per cent.
