ANNUAL REPORT OF NEW YORK 
TOBACCO-WORM. THE WORM DESCRIBED. 
formed of a series of curves on the spaces between the veins, with their 
ends turned backward and forming angles upon the veins; and at the tips 
of these wings is a black oblique line, corresponding with that upon the 
upper side, but much more slender and simple. The hind wings are gray, 
with their hiud border brown, and are crossed by two blackish bands, which 
are repetitions of the two middle bands of the upper surface, but more dim, 
more slender, and running back upon the veins in longer and sharper points. 
The Larva grows to the thickness of one’s little finger, and is somewhat 
over three inches in length or three and a half inches when it is crawling, 
it being then more elongated than when at rest. Its surface is destitute 
of hairs or bristles. It is divided into thirteen segments, those at each end

being shorter and less distinct. The surface of each segment of the body 
is crossed transversely by impressed linesand roundly elevated intervening 
spaces, giving them a ribbed appearance, there being eight of these eleva¬ 
ted ribs to each segment. In viewing this larva the eye first of all notices 
a formidable looking, stout, thorn-like horn, placed at the hind end of tho 
back, and projecting obliquely upward and backward, about as long as the 
segment which is next forward of it, slightly curved, and its surface rough 
from little projecting points. Low down upon each side is a row of largo 
oval dots, which are the spiracles or breathing pores. The head is small, 
horny and shining, of a flattened spherical form, and the month furnished 
with a pair of stout jaws. It has three pairs of small tapering feet placed 
anteriorly upon the breast, each having a sharp hook at its end, and four 
pairs of short, thick, fleshy pro-legs along the underside of the body, with 
two similar ones at the tip. 
The color of this worm is commonly bright green marked with white. 
Numerous faint whitish dots are usually perceptible, at least on the fore¬ 
part and underside of its body, and along each side are seven straight oblique 
stripes, the last one of which is prolonged more or less distinctly to the 
base of the curved horn. These stripes arc usually margined along their 
upper sides by a faint dusky cloudiness; and meeting their lower ends is a 
longitudinal stripe, placed low down upon each segment, and forming, with 
the oblique stripe, a V-shaped mark, having its point directed forward, with 
the breathing pore placed in the angle which is thus formed. Tho hind¬ 
most breathing pore also has a much shorter and more faint white stripe
