the parasites, while the latter, if allowed to go through their changes, 
may do good service to the next generation of caterpillars. 
Smerinthus (Paonias) excalcatus, Sm. and Abb— The Blind-eyed 
Sphinx. 
The caterpillar of this sphinx is, according to Dr. Packard, “apple 
green, with seven oblique, yellowish-white lines on the sides, and a 
bluish caudle horn.” It feeds on the apple and some kinds of roses, 
but is not generally numerous. The moth has the dentate lore wings, 
rich brown, crossed by two broad bands of lilac-gray ; the hind wings 
rose colored at the base, brownish in the outer part, a black, eye-like 
spot near the anal angle pupilled with blue. Body brown ; antennae 
pectinate beneath in the male. Wings expand three inches. 
Smerinthus (Cressonia) juglandis, Sm. and Abb.—The Walnut 
Sphinx. 
This caterpillar is bluish green, with a row of sub-dorsal and stig- 
matal reddish brown spots, and six oblique lateral bright yellow 
bands.”—Packard. It feeds on walnut and hickory leaves. 
The wings of the moth expand from two and a half to three inches, 
are both a pale lilac gray, and have no eye-like spots on the hind 
wings. 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 brown lines, about a tenth of an inch apart, that 
cross both the fore and the hind wings; near the body, two similar 
lines that cross only the fore wings. Antennae pectinate beneath in 
the male. 
Ceratomia amyntor —Hub.—The Elm Sphinx. 
This moth, called by Dr. Harris C. quadricornis , or the “four-horned 
Ceratomia,” is one of the largest that is found on the elm, and is the 
only Sphinx caterpillar in this country that has thoracic horns or 
projections. When fully grown they are “ about three inches and a 
half in length, of a pale green color, with seven oblique white lines 
on each side of the body, and a row of little notches, like saw teeth, 
on the back. The four short horns on their shoulders are also notched, 
and, like most other Spinges, they have a long stiff spine on the 
hinder extremity of the body.”—[Harris.] They pupate in the 
ground, the single brood of the season passing the winter in that state. 
The moth has an expanse of wings of three and a half inches. The 
general color is brown, light along the prothorax and costa of the 
fore wings, but darker through the middle except at the base, with 
four oblique, dark brown, elongate spots in this darker portion, the
