ANNUAL REPORT OF NEW YORK 
ELM. LEAVES. 
Of measure worms , having but ten feet, there are 
The Canker worm, $ 38, the V-mariced measure worm, § 39, and 
the New York measure worm, (Erannis subsignaria, Hubner,) which 
has been so noted a pest for many years in the metropolis of our State, and 
is most destructive to the lindens, under which the description of it will be 
given. 
Of worms which are peculiar to the elm, or are more common on this 
than other trees, there are several, which are not yet known to me in their 
perfect state, and I have but one species to present at this time. This is an 
inhabitant of northern Europe, and has not been known hitherto as occur¬ 
ring also upon this continent. 
344. November moth, Oporabia dilutala, Schifferrmyllcr. (Lopidoptcra. Goometridre.) 
Feeding on the leaves in spring, a dirty green measure worm, beneath 
paler bluish white, its breathing pores forming a row of orange red dots 
along each side, where is sometimes a yellow line also; living openly 
exposed upon the leaves and in the summer entering the ground to pass its 
pupa state; the moth coming out in November, its wings usually as thin 
as bank note paper and semi-transparent, very pale gray, the fore pair 
with faint indistinct transverse marks of a darker color, whereof two near 
to and parallel with the hind edge are commonly the most distinct, and two 
others extending from the middle of the inner margin to a small dusky 
streak in the centre of the wing, the hind wings fringed all around with 
whitish hairs. Width about 1.30. 
Slowly flying among the leafless bushes upon mild days in November I 
have met with this moth. It coincides so perfectly with the figures and 
accounts given of the European November moth, as it is termed in 
English works, that I cannot deem it anything else than the same species. 
A more accurate representation of my specimens could scarcely be made, 
than is the figure of the pale variety of this species, in Westwood and Hum¬ 
phrey’s British moths. It is often more fully and distinctly marked, 
according to the statements of authors, than in the specimens from which 
the above description was taken. So extremely variable is it, that nearly 
a dozen species have been made from its varieties, by different writers. 
345. Ladder Ciirvsomela, Chrysomcla, sealaris, Le Conto. (Colcoptcra. Chryso- 
mclidao.) 
Feeding upon the leaves throughout the season, a shining hemispherical 
bottle green beetle with silvery white wing-covers, on which are several 
bottle green spots and a broad jagged stripe on their suture, its wings rose 
red and its antennae and legs rusty yellow. Length 0.30 to 0.40. Com¬ 
mon also upon willows. 
340. Ei,m Galerdca, Galcruca Calmariensis, Linnaeus. (Colooptora. Galcruoidco.) 
An oblong oval beetle 0.25 long, of a grayish yellow color with three 
small black spots on its thorax, a broad black stripe on the outer part
