a slender line on the head and thorax, the shoulder-covers, and a 
transverse patch on the top of the first abdominal segment, dark 
olive. Expands from four to four inches and three quarters. 
Larva, when young, pea-green, with a slender recurved caudal 
horn, and of the same color or of a clear light brown and without 
a tail afterwards, with six oblique broad oval cream-colored spots 
on each side of the body; feeds on the leaves of indigenous and 
exotic grape-vines, and on those of Ampelopsis hederacea, and 
enters the earth to transform.

Red-ash colored ; fore-wings with a few short transverse brown 
lines, and shaded with brown from the middle to the hind mat- 
gin, with a square spot near the middle of the inner margin, an- 
other near the tip, and a triangular spot near the hind angle, of a 
deep brown color ; hind-wings pink, with a deeper red spot neat 
the inner margin, a dusky hind border, and a transverse row of 
small black spots; palpi and a large triangular spot on each shoul- 
der-cover deep brown. Expands from three to four inches. Larva 
pea-green with a slender recurved tail when young, of the same 
color or light brown and without a tail subsequently, with six 
oblique oblong oval scalloped cream-colored spots on each side. 
It eats the leaves of grape-vines and of the common creeper OF 
Ampelopsis. 
This and the preceding species, in the larva state, are very in- 
jurious to our cultivated grape-vines.

This genus was established, in 1835, by M. Duponchel,* to 
receive certain European Sphinges the larve of which have the 
head and fore-part of the body retractile, the head being very. 
small, and the first three segments abruptly diminishing in size 
from the fourth, which gives to the fore-part of the body @ tT 
semblance to the head and snout of a hog. Hence the F rench 
name of these larvae, cochonnes, and the generical name proposed 
by Duponchel, which is derived from yorgos, a hog, and xis @ 
caterpillar. 'This peculiarity in the form of the larve seems (0
