FRUIT-TREE LEAF- ROLLER ( Archi ps argyrosnila nr alk.) 
New York P. D. Rupert (April 16): A few egg masses have been observed on 
apple in Dutchess County. 
E. W, Pierce (April 17): Eggs have been noticed in 'orchards in 
every section of Ontario County. 
P. J. Chapman (April 14): Eggs have been observed in several 
orchards in Genesee County. 
Idaho Claude Wakeland (March 16): Fe have recently been making soir>e 
egg counts on this insect, preparatory to experimental spraying, 
and find that in the orchard in question the average increase of 
infestation for the year is a little more than 300 per cent. On 
one tree only there was a decrease in the number of egg masses , and 
the extremes varied to as great an increase as 1,400 per cent. Our 
method of determining the rate of infestation and increase is to 
count all egg masses on a given branch or portion of a tree and to 
remove all eggs that have hatched on previous years. (T'arch 30): 
Count of the egg masses on 11 trees at Lewiston showed an average 
of 28 old egg masses and 64 new egg masses per tree. The infesta- 
tion this year is approximately 238 per cent of that of any previous 
year. 
BRUCE* S PLEASURING TJORM ( Rachela bruceata Hulst) 
Washington A. L„ L'elander (April 20) : V7 e have just received specimens from 
Tonasket in the Okanogan Valley of what was thought to be the bud 
moth. It proved, however, to be Bruce' s measuring worm. This 
material was sent in by Thomas Thorson, who previously had sent 
specimens of last year's apples bearing stings very similar to 
those caused by codling moth larvae. His statement about the 
stings was that the stinqs were prevalent in unsprayed as v/ell as 
in sprayed orchards, and were attributed to the summer generation 
of the bud moth. The measuring worm was now sent in as the spring 
generation of the bud moth. Ve have not been able to diagnose 
what is responsible for the stings on the mature ancles, although 
the codling moth and the lesser apple worm are both present in his 
region. This is the first record we have in Washington of the 
occurrence of Bruce 's measuring worm. 
TENT CATERPILLAR ( Malacosoma ame.ric ana Fab.) 
New York P. J. Chapman (April 14): Eggs have been observed in several 
orchards in Genesee County. 
E. W. Pierce (April 17): Eggs have been noticed in neglected 
orchards in Ontario County. 
Massachusetts A. I. Bourne (April 23): The apple tent caterpillar appears to be 
very scarce at Pittsfield, Berkshire County; few, if any, egg masses 
are to be found except on wild cherries or on scattered, uncared-for 
apple trees. A letter from northeastern Essex County reports 
"millions" of apple tent caterpillar egg masses, greater numbers than 
have been seen for years, and on April. 19 one or two egg masses "-ere 
found to be just beginning to hatch.
