Description.—Head brown, margined behind with. orange. 
Probuscis short, pale yellow, spirally convoluted between the 
palpi, which are large, subtriangular, yellow, the apex and mi- 
nute terminal joint black. Antenne one-third the length of 
the body, setaceous, not pectinate, brown, the first joint, which 
is thicker than the rest, yellow. Thorax brown, with two inter- 
rupted irregular transverse bars of orange. Upper-wings brown, 
beautifully variegated with many irregular streaks of orange, and 
a few of silver. The silver streaks are situate chiefly next the 
margin: one just above the middle of the wing, anteriorly di- 
viding into a fork, whose ends approach the margin; another 
below the middle, extending in a curved direction nearly to the 
apex, and sending off anteriorly two or three branches towards 
the margin. These silver lines are margined with orange, as are 
two other short transverse silver lines near the inner angle of the 
apex of the wing, which include a small silver spot, and two 
longitudinal orange bars. Besides numerous orange streaks and 
marks, which it is unnecessary to describe minutely, the wings 
are characterized at the outer margins by about six short oblique 
yellow spots. At the apex they are fringed with brown cilia, 
which in some lights have a metallic shade, and are interrupted 
by two longitudinal bars of yellow cilia. Under-wings, above 
wholly of a brownish black, except at the outer margin from the 
base to the middle, where they are white. At the apex they are 
fringed with cilia, white at the apex, and circumiscribed just’ 
above the brown base with a very fine and almost imperceptible 
white line. Under-side of the body and legs of a silvery or 
pearly white; the ili and ¢arsi of the latter ringed with black. 
Length of the body about one-third of an inch; of the wings, 
when expanded, from half to three-quarters of an inch. 
Long as the above description may seem, it will not be deemed 
too minute by any one acquainted with the difficulty of discri- 
minating many of the minuter species of this tribe of insects; 
nor could I have contracted it consistently with the object I have 
in view, that of enabling any gardener to recognise the moth in 
uestion. 
How long these moths live after being excluded from the 
chrysalis, I am not able to say; but from analogy, and the cir- 
cumstance that some which I reared under a glass jar did not 
survive above a week, I conclude their term of existence does 
not much exceed that period. Hence, as I find them in my 
garden from May to the middle of August, it is clear that they 
are not, like many other insects, confined to one term of exclu- 
sion, but are issuing from the chrysalis throughout the whole 
summer: in greater number, however, in June than afterwards. 
In the day-tiine they usually remain sitting at rest on the trunks
