doubtless be Phyllocnistis vitegenella. 
The larva mines the leaves of Vitis cor- 
difolia in an exceedingly long, winding, 
narrow track, just sufficiently broad to 
accommodate its body. The track is not 
transparent, and the entire parenchyma 
of the leaf is not consumed, so that in 
appearance it is not unlike the tracings 
left by snails. Just before undergoing 
its transformation the larva enlarges its 
mine sufficiently to enable it to throw 
the leaf into a small fold and weave its 
cocoon. 
The larva is without feet or prolegs. 
The body tapers posteriorly somewhat, 
with the sides of the segments slightly 
projecting, but flattened, and the middle 
cylindrically elevated. The head is thin, 
flat and circular, with the mandibles 
forming an appendage in front on the 
median line. The head is umber- brown. 
The body shining, translucent, whitish 
on the sides and dark green in the 
middle. It is somewhat viscid, adhering 
to whatever touches it after the larva is 
taken from the mine. When this is done 
it makes little or no voluntary movement, 
and does not retreat in its mine when 
touched. The larva is apparently very 
delicate and is easily killed, indeed does 
not survive the gentlest handling and 
examination. * * * * * 
In the leaf of the same plant ( V . cor- 
difolia ) I found, a few weeks since, 
another Anlispila larva; another much 
larger one in a species of domestic grape 
(“The Isabella”); another in a species 
of Cornus , and another in the leaf of the 
Hickory. 
Aspidisca splendoriferella. Aspidisca 
is a genus very close to Anlispila. The 
mine of the larva is similar, but much 
smaller, and although the cocoon is very 
small, but little of the mine is left after 
the membranes of the leaf are cut. It 
feeds on the leaf of Cralcegus tomen- 
tosa. 
The larva has the head much smaller 
than the first segment, rounded above 
and elliptical. The body is flattened 
and tapers from the anterior rings, but 
the first ring is smaller than the second. 
The segments are rather deeply incised, 
the thoracic obtusely rounded at the sides, 
and the remainder each with a lateral 
nodule or mamilla. Without legs or 
prolegs, but on the second and third 
thoracic rings, both on the ventral and 
dorsal surfaces, are spots or cup-like de- 
pressions, two on each ring, capable of 
being contracted and expanded ; so also, 
from the sixth to the ninth inclusive, on 
the ventral surface are oval central spots 
of a similar kind, one on each ring, and 
on the ring next the last is a protuber- 
ance, both dorsal and ventral, with two 
cup-like depressions on each surface. 
These are not supplied with hooks, and, 
if they are substitutes for feet, must act 
like suclcers. These cup- like depressions 
are pale brown ; the head dark brown ; 
the body brown, [tinged] with blackish 
along the dorsal and ventral surfaces. 
The mine is a small transparent blotch, 
but little larger than what is sufficient to 
form the case, with the “ frass ” deposited 
collectively. The case is oval, rather 
pointed at the extremities, and is secured 
to some object by one of its ends tied 
down on a little white silken button. 
The larva carries the case quite a distance 
some time before finally securing it. 
As the perfect insect is very small, 
I will give you its characters, and beg, 
when your specimens appear, that you 
will verify my diagnosis. 
Head smooth. Ocelli none. Forehead 
or vertex rounded. Eyes very small, not 
visible from above and scarcely visible in 
front. Antennse held extended laterally,
