ANNUAL REPOUT OF NEW-YORK 
CURRANT. STALKS. 
or livid color, shining, with a chestnut-colored head and a horny- 
spot of the same hue on top of the neck and of the last segment, 
and with faint dots symmetrically arranged, each yielding a very 
fine short hair. Burying itself about a month, the moth coming 
out in July, its fore wings rusty red clouded with gray and black¬ 
ish, with the usual round and kidney-shaped spots near their 
centre large, pale gray or white, and beyond these spots a broad 
bluish-gray band parallel with the hind margin and not reaching 
the outer edge, this baud margined on its hind side by tawny yel¬ 
low followed by a wavy white line extending across the wing and 
ending outwardly in a large gray spot which occupies the tip. 
Colors and marks sometimes dull and obscure, sometimes bright 
and distinct. Width 1.80. 
This is one of our most common night-flying moths. Having 
been found arranged with British species in some old English col¬ 
lections it was supposed to be a native of that country and was 
described as such by Mr. Stephens, who conjectured it to be the 
species named arnica by Treitscke. Now that it is so evident that 
this was an error it is improper to continue using this name for 
this species, and I therefore propose for it a new one having refe¬ 
rence to the habits of the larva, this being the first characteristic' 1 
which comes into the mind, commonly, when this insect is thought 
of. By this insect in addition to the borers above mentioned 
Nature endeavors to lop off all that redundancy of stalks which 
the roots of the currant produce and which man neglects to 
remove. See Harris’s Treatise, p. 350. 
Apple bark louse, No. 15. I have occasionally seen the bank 
of both the garden and the wild currant crowded with these 
minute oyster-shaped scales, the stalks being commonly dead in 
consequence of their attack. A currant stalk thus excessively 
over-run may be seen in the Entomological Museum of the Society. 
139. Circular bark louse, Jlspidiotus circularis, new species. (Ilomop- 
tera. Coccidue. 
On the bark of currant stalks in gardens of the city of Albany, 
early in the spring, I have observed a minute circular flat scale, 
only 0.03 in diameter, similar to a species named Jlspidiotus Amu 
but differently colored, being of the same blackish brown hue 
with the surrounding bark and having in the centre a smooth 
round wart-like elevation of a pale yellow color.
