and thrown back over the dorsum of the thorax, which they equal in 
length. In colour and appearance the sexes do not differ. In repose, 
the À labial palpi are closely applied to the thorax in the living speci- 
men, and from their pale ochrey outer colour have-the effect of thoracic 
vittæ. In my original description I call them blackish “ outwardly;” the 
exposed upper portion is pale or ochrey, else they are blackish. In the 
_dried specimen they are apt to become a little elevated. A. agrotipennella 
varies in the obsolescence of the discal ochrey shades, while the pale 
submedian dash itself is sometimes a little indistinct. I have already 
noted that Dr. Clemens’ A. Popeanella disagrees with A. agrotipennella by, 
among other characters, its being described as luteous along the inner 
margin ; that authors description of A. arcanella better agrees, but this 
must be decidedly distinct also, since Dr. Clemens places 4. arcanella in 
a distinct section ; labial palpi shorter in the 2 than in the other species ; 
ascending but not recurved. This character is totally opposed to our 
species, in which the À labial palpi are as long as in A. plumifrontella, 
which latter species I have taken at night at Hastings, on the Hudson, 
N.Y., in July. There is a certain correspondence in the position of the 
dark spots on the fore wings in this genus, which gives a similarity to the 
specific diagnoses.

In the spring of 1871, my attention was attracted by the peculiar 
manner in which many of the leaves of the Laurel Oak (Q. imbricaria) 
were rolled up. ‘The cases thus formed were compact and cylindrical, 
varying in length from one third to one half an inch, by an average 
‘diameter of one-fifth of an inch, and very neatly finished up. Several of 
them were opened, and each found to contain a single, smooth, spherical, _ 
_translucent-yellow egg, about 0.04 inch in diameter. Desirous of rearing 
the insects, I collected quite a number of the interesting little nests, and 
_ watched, with much curiosity, for the larvæ to appear—not knowing, at 
that time, what to expect. But my observations were not rewarded; and, 
after several weeks of impatient waiting, I made another examination into 
the contents of the now blackened and shriveled up cases, and found two 
or three very small larvæ, dead and shrunken, but evidently of some 
curculio,
