Description of the Larva of Sphinx luscitiosa, Clemens. 
By Harrison G. Dyar. 
Head, shagreened, of a grass green color with two paler green 
stripes edged posteriorly with a darker shade. ‘Tips of jaws and eyes 
black. Body, pale green, slightly darker on the posterior segments. 
On joints 3 and 4 are sparsely distributed white dots, each surrounded 
by a fine black ring. These spots are also found on the venter and sub- 
ventral space for the entire length, but diminish in number on the post- 
erior segments. Seven oblique lateral lines on joints 7 to 12, the last 
one extending from the base of joint 11 over joint 12 to the caudal horn. 
These stripes are white, shaded anteriorly with dull crimson in which is 
situated near the edge a very fine black line. Caudal horn green, with 
a black stripe on each side, this being the continuation of the posterior 
oblique lateral line. Thoracic feet pale yellowish, tipped with pinkish. 
Spiracles, reddish. The length of the mature larva is about 60 mm. 
The food plant is said to be Willow, which I believe to be correct. 
The larva from which the present description was drawn was found, 
fully grown, in a little stream over which bushes of Willow extended. It 
was nearly drowned and had barely strength enough to revive. 
Sphinx luscitiosa is single brooded. 
Pupation occurring in July, 
Larva from Ulster County, N. Y.
