CHE LESSER APPLE WORM. 59 
At Nebraska Ci... |, Nebr., during 1906, Mr. Dudley Moulton found 
full-grown larve in apples during late June and early July, moths 
issuing from July 6 to August 24, reaching their maximum, however, 
during late July and early August. The pupal stage was found to 
last from fourteen to sixteen days. 
In 1905 full-grown larvee were found in wild plums as early as 
April 28, at Fort Valley, Ga., and during the same spring mature 
larve were received in a sending of Japan plums from Garrison, 
Tex., by Prof. F. W. Mally, under date of May 20; and also in wild 
plums sent in by Mr. C. R. Jones, from Ardmore, Ind. T., a few 
days later. 
At least two annual generations of larve are evident, though in the 
more northern States the second may prove to be only a partial one. 
Larve are notably later in leaving the fruit in the fall than is true 
_ of the codling moth, and are hence very commonly found at picking 
_ time, and it is likely that their occurrence has thus led to belief in an 
additional brood of the latter species, especially on the part of 
-orchardists. Owing to their comparatively small size the larve may 
be readily overlooked, especially when in the calyx end, and infested 
fruit thus often goes into the barrels. In several instances which we 
have noted, important injury has been done by the larvee to barreled 
fruit, the disfigurement of the surface being especially common.

IDENTITY. 
The recorded feeding of this insect upon such diverse food as the 
~“ black-knot ” of plums, elm and oak galls, and upon apples, plums, 
and Crategus, naturally brings up the question of the identity of 
the insects secured from these several sources. On this point Walsh 
Wsays: 
Three specimens bred from Black-Knot Aug. 31—Sept. 7, three others bred from 
the Elm Gall (Ulmicola Fitch) July 24-Aug. 5, and a single one bred from Oak- 
Gall (Q. singularis Bassett) on Sept. 2, none of them differed from the plum- 
fed specimens in any important point. I sent a single specimen bred from the 
‘Black-Knot to the late Dr. B. Clemens about a year before his lamented death ; 
but he never, so far as I know, investigated its classification. For the satisfac- 
tion of the incredulous I may add that I sent specimens bred respectively from 
the Plum and Elm Gall to the distinguished English entomologist, H. T. Stain- 
ton, who is well known to have made the smaller moths his special study for 
years ; and that he agrees with me that they are perfectly “ identical.” 
Also according to Stainton, as stated by Walsh, the species is most 
closely allied to the European Semasia janthinana Dup., which has 
also been bred from gall-like growths on hawthorn twigs. Riley also 
records breeding the species from galls (Quercus frondosa Bass.), in 
the Third Missouri Report, page 25. No further records of the insect
