13. THE BLACK WALNUT .—Juglans nigra. 
The Locust-tree borer (Clytus Robinice) is a common borer in 
the trunks and limbs of the black walnut, and the beetles which 
are reared in this tree appear to constitute a distinct variety of a 
larger size than usual and with their yellow marks changed more 
- or less to a white color. 
18G. Black-Walnut Sphinx, Smerinthus Juglandis, Abbot and Smith. 
(Lepidoptera. Sphingidae.) 
Eating the leaves, a large pale blue-green worm tapering in both 
directions from its middle and with a small head, a long horn at 
the end of its back and seven oblique white streaks along each 
side; when irritated making a creaking noise by rubbing the 
anterior joints of its body together; burying itself under ground 
through the winter and changing to a chestnut colored pupa with 
a rough granulated surface and six small tubercles upon its head; 
producing a narrow-winged moth of a drab gray, cinnamon-yellow 
or bluish lilac color, its fore wings crossed by four rusty brown 
lines, the two forward ones transverse the two hind ones parallel 
with the hind margin, and with a large square rusty brown spot 
on the middle of the inner margin between the two middle lines. 
Width 2.25 to 3.00. See Silliman’s Journal xxxvi, p. 292.

bycidse.) 
Under the bark of old decaying trees, a grub similar to that of 
the Prickly Leptostylus No. 4, changing to a pupa in its cell and 
early in July giving out a small thick long-horned beetle of a 
brown or chestnut color with the sides of its thorax and a band 
on its wing covers ash-gray, the latter sprinkled over with coarse 
punctures and large blackish dots, the thorax on each side of its 
disk with a black stripe interrupted in its middle. Length 0.25
