The full grown larva is usually found during the latter part of 
August and fore part of September. It measures about 3J inches 
when crawling, which operation is effected by a series of sudden 
jerks. The third segment is the largest, the second but half its 
size, and the first still smaller, and when at rest the two last men¬ 
tioned segments are partly withdrawn into the third, as shown in 
the figure. The young larva is green, with a long slender reddish 
horn rising from the eleventh segment and curving over the back, 
and though I have found full grown specimens that were equally 
as green as the younger ones, they more generally assume a pale 
straw or reddish-brown color, and the long recurved horn is invari¬ 
ably replaced by a highly polished lenticular tubercle. A line of 
dull brown, deep and distinct on the anterior and indistinct on the 
posterior part of each segment, runs along the back, and another 
of the some color, continuous, and with its upper edge fading grad¬ 
ually, extended along each side. The six scalloped spots are cream- 
colored, the head, thoracic segments and breathing holes inclined to 
flesh-color, and the pro-legs and caudal plate were deep-brown. 
The worm is covered with minute spots, which are dark on the 
back but light and amulated on the sides, while there are from six 
to eight transverse wrinkles on all but the thoracic and caudal 
segments. (Riley.) A magnificent larva found generally over the 
entire West, but never abundant, and hence never very injurious. 
Feeds on leaves of Grape vine and American Ivy. 
Ceratomia amyntor, Hub. 
The body is pale green and strongly shagreened. It has six or 
seven oblique whitish bands on each side, the first and last of which 
are longer than the others. On the second and third segments there 
are four short, obtuse horns, which are also notched. The caudal 
horn is whitish-green, of medium length and slightly curved. The 
stomata are black, surrounded with yellow and crossed by a yellow 
line. Length about 3^ inches. It is found in May and June. 
Feeds on the American Elm (Ulmas americana). The larva enters 
the ground to transform. 
Daremma brontes, Boisd. 
The larva is pale green, marked with seven oblique bands on each 
side, which are whitish, shaded with deep green. Head green, 
marked with two narrow reddish lines. Horn green, tinged with 
rosaceous, rather large and slightly arcuate. 
Feeds on various species of Ash ( Fraxinus )., especially on F. 
americana , F. simplicifolia, and F. platycarpus.
