part of the wing; within it is‘a darker band with a still 
darker straight inner edge. Outside of the pale band are 
several indistinct lines crossing the wing, a dark brown 
spot just inside of the anal angle and a lunulate spot of the 
same color edged on the inside with white. The hind-wings 
are rosy red, with gray costal and outer borders. There is 
a large black spot with two blue spots on it near the anal 
angle, and connected with it by a narrow, black stripe. 
Occasionally a third blue spot appears, but sometimes there 
is but a single one. 
The globose eggs are somewhat flattened, and of a pale 
green color. 
THE WALNUT SPHINX. 
_(Cressoma juglandis 5. & A.). 
This is still another Sphinx closely related to the pre- 
ceding species, but quite different from them, as it lacks the 
bright eye-like spot upon the hind-wings. The moth, which 
expands two.and a half to three inches, is uniformly light 
brown or pale lilac-gray (Fig. 57, Plate VIII). The fore- 
wings are somewhat clouded with brown in the outer part 
and also through the middle. Near the outer margin are 
two fine parallel lines, about a tenth of an inch apart, that 
cross both the fore and hind-wings; near the body are two 
similar lines which cross only the fore-wings and enclose a 
square dark-brown spot adjacent to the middle of the inner 
margin. The females are much larger, and of a lighter 
brownish-gray color than the males, with the square spot 
on the fore-wings less distinct. The antennz are pectinated 
beneath in the male. 
The caterpillar is of a pale brownish-green color, with a 
long caudal horn. It has a small head, and the body is at- 
tenuated before and behind; there is a row of sub-dorsal 
and stigmatal reddish-brown spots, and seven oblique, lat-
