twigs at or near the crotch formed by the leaf and twig, the point of 
entrance being indicated by a little mass of brown excrement. 
The egg had evidently been placed in the protection formed by the 
two little spurs at the base of the petiole. Subsequently many other 
eggs were obtained from other moths, and they were, for the most part, 
similarly situated, namely, around the base of the leaves. In one 
instance nine eggs were deposited around the base of a single leaf, six 
of them close together under one of the bracts at the base of the petiole 
and three in the depression or sear left by the second bract, which had 
dropped. 
The recently deposited eggs are white in color and iridescent, but 
becoming before hatching distinctly orange. They measure about four- 
tenths of a millimeter in length by two tenths of a millimeter in breadth, 
are somewhat ovoid, and are lightly attached lengthwise to the twig by 
a glue-like material. Under a high power 
they are seen to be coarsely and rather regu- 
larly reticulated, as shown in the illustration 
(fig. 4). 
In confinement the moths live about ten 
days and most of the egg-laying is in the first 
half of this period. The habits above de- 
scribed are those of caged moths, but it is 
reasonable to suppose that in a state of nature 
the eggs are deposited in much the same way, 
and this is rendered almost certain by the 
great regularity noted in the manner of their 
deposition. In but one or two instances were 
the eggs placed in other situations—one being

From eggs deposited later than those first rapier Yeas aa 
mentioned, viz, about June 3, larve appeared June 15, indicating a period 
of about twelve days between the laying of the egg and its hatching. 
Most of the larvie coming from the first lot of eggs had cast one 
skin when discovered. The smallest larvie found measured about 1 
millimeter in length and were of a very pale yellow color, with the head 
and cervical and anal plates black and the thoracic legs dusky.. They 
had excavated channels somewhat longer than themselves and about 
twice as broad into the twigs, the entrance being marked by a small 
mass of excrement. By June 3 most of these larve had abandoned 
their original burrows and were constructing new ones in similar situa- 
tions on fresh branches of the peach, with which they were from time 
to time supplied. This they continued to do, viz, to construet new 
burrows every few days, until they were full grown. On June 23, of 
the three remaining individuals of this lot of larve, one had already
