pupated ill a lolded leal and the other two were fully grown and about 
ready to transform, which tliey both did before the end of the month. 
About the <Mid of .lune Mr. Ehrhoni sent us some ])eaches said to be 
infest«'d witii \\w second brood of larva'. Some of the peaches had 
been Itorcd into a little way near the stem by what was evidently, from 
the si/c and nature of the burrows, nearly full-^m)wn larva* of the sec- 
ond brood. One of these was found, and also (»ne i)Upa. (Jn further 
examination, however, it was discovered that the larva- of what is 
un<loubtedly the third brood — the second of the summer broods — were 
l)rescnt in numbers, not in the fruit, but in the short stems of the fruit 
which at this season are green and somewhat succulent. In these 
stems they had made their little elnnnbers not unlike those in the twigs 
above described or those in the crotches in the fall, exeei)t that they 
were for feeding })uriK)ses and not lined with silk, as are the latter. 
Others were also found at the base of the leaf stalks just as we had 
been finding them in our breeding cages. 
Wc were unable to carry our breeding-cage material farther than this 
point at Washington, and Mr. Khrlioni was unable to furnish additional 
supi)lies, but he writes that he found the minute larva* in the crotches 
of the trees as early as August 21. It would seem from this last and 
very important observation that some, at least, of the fourth brood of 
larva', if not all of them, go into winter quarters and at a period much 
earlier than would have been supi)Osed. 
These facts go a long way toward clearing ui) the life hist(uy of this 
insect, and indicate a much more uniform habit in the different broo<ls 
than has hitherto been sui)posed. 
The old idea that this insect is double-brooded, the tirst brood living 
in the twigs and the second brood affecting the ripening fruit, must be 
abandoned. At the time of the appearance of the first brood of moths 
during the month of May the fruit of the peach is of considerable size, 
especially by the end of the month, but is green, hard, and densely 
hairy, and is ])robably rarely if ever chosen l)y the parent iiKJths as a 
nidus for her eggs. The m)rnial locatitm of the H'fig^ and the \Hnut at 
's\iiich larval development begins is indicated by the foregoing notes, 
and there is no reason to doubt but that at all seasons of the year 
larva' develop in the new growth, entering normally at the axils of the 
leaves or in the stems of the green fruit. In these situations the eggs 
are i)laccd and the young larva* construct their little oval chambers, 
which they abandon from time to time to make new ones, rarely doing 
enough danmge in the later broods at any one point to be noticeable. 
As they attain larger si/e they travel more and often bore into fruit near 
the stem, where the greater exudation of gum and more serious character 
of the injury draw attenti<>n to them. In the case of the burrows in the 
twigs the more abundant new growth and more mature condition of 
the wood render tlie injury much less noticeable, nor are the results of 
the attacks so nuirked as in tlit* injury to the new growth in April.
