HICKORY. LKAVKS. 
whilst in Selene no such ring occurs. The spot on the fore wings is much nar¬ 
rower and of an elliptic form, but has all the parts of that upon the hind 
wings. In Selene this spot appears to be more distant from the fore margin 
of the wing than it is in Luna, and is destitute of the brownish red streak 
which we see in Luna extending from the outer corner of this spot obliquely 
forward to the border of the wing. 
181. Polyphemus moth, Hyalophora Polyphemus, Fab. (Lepidoptera. Bomby- 
cidse.) 
In August and the fore part of September, a large thick-bodied 
worm closely resembling that of the foregoing species, 3.50 long 
and of an apple green color, not darker green beneath but having 
a pale yellow stripe along the middle on its under side, and on 
each segment six bright orange conical points, three on each side, 
with a sulphur yellow stripe from the lower to the middle one of 
these points, except on the anterior segments, and the upper 
points sometimes silvery on their outer sides; its head and six 
anterior feet of a clay-yellow color; crawling along the under 
sides of the limbs with its back downwards, its body being too 
heavy to be sustained in an upright posture; when at rest and 
contracted each segment strongly humped and forming an angular 
transverse ridge; constructing a cocoon in all respects like that 
of the Luna moth, which gives out the perfect insect the middle 
or latter part of May; this of a dull ochre or brownish yellow 
color with a glassy eye-like spot near the middle of each wing, 
crossed by a slender line and margined by a yellow succeeded by 
a black ring, which last is much broader on the hind wings and 
ou its forward part is widened into a large cap-shaped spot as 
long as wide, with its concave end shaded into a bluish-white 
crescent; a dusky band faintly margined with white on its hind 
side crosses both wings forward of their hind margin, beyond 
which the ground color is commonly paler; anterior margin gray, 
which color is continued from the wings across the thorax in the 
form of a band. Width 5.00 to 6.50. A specimen in the col¬ 
lection of I. A. Lintner of Schoharie is much the smallest I have 
ever seen, measuring only four inches across its spread wings. 
I have met with the larva of this insect on walnut, butternut, 
thorn and linden or basswood, and Dr. Harris (Treatise p. 298) 
records its occurrence on oaks and elms also. It sometimes at¬ 
taches its cocoon partly to the side of a limb or sometimes with
