W. B. Mabee (June 17): On June 3 overwintering larvae and sorr.e 
pupae were found in the orchard home section near Missoula, Liv- 
ing specimens v.ere considerably easier to find than usual at this 
season. 
S. J. Newcomer (June 1): First adults of the codling moth were 
observed May k. Continued cool weather during the latter half of 
ifey has prevented oviposition, and this, together with some '-ante 
mortality, should make the codling moth a less serious pest in th 
Pacific Northwest this year than for several years past, Unfavor 
able weather has made it difficult for growers to apply the calyx 
spray at the right time. The first favorable weather for oviposi 
tion of any consequence occurred May 31 and June 1.

EASTERN TENT CATERPILLAR ( Malacosoma a mericana Fab.; 
J. V. Schaffner Jr. (June 17): Forty-eight reports received fron 
various localities throughout New England seem to indicate that 
the infestations are spotty. Have noticed in some of the to- 
rn eastern Ma ssachu. setts heavy infestations in one part of the 
town and very 'light in other parts. 
M. P. Zappe (June): Many larvae show tachinid eggs, .Many larvae 
also dying of wilt disease. 
A. I. Bourne (June 20): The apple tent caterpillar has been abou 
as abundant as. last year. No appreciable increase i'n abundance 
has been reported from any section. If anything, there has beer. 
a slight decrease in their numbers. At the time of our April re- 
port, I gave some preliminary figures relative to parasitism. 
Since that time we have dra'.7n deductions of counts from about 
13,000 eggs of this insect and found that the avei parasitism 
for this number was 7-22 per cent. The egg masses showed an 
average hatch, of between 85 and 80 per cent. The amouat of para- 
sitism was found to vary considerably according to "egg masses, 
ranging from up to 27 or 28 per cent. From the average percent 
age of parasitism, however, it would not appear that we could de- 
pend on the natural enemies of this insect to reduce it materiall 
by the next season. The larvae had, "oy early June, for the most 
part, completed feeding and had begun to crawl about. The first 
cocoons were noted about the 12th to lUth. 
E. P. Felt (June 2k): The apple tent caterpillar, . alacosoma 
amer i cana , is reported as numerous throughout Monroe COtinty, com- 
pletely stripped trees being seen ("'m. L. 5. Edson). This insect 
is apparently more common than ever in this section (R.E.Hors<
