SMERINTHUS JUGLANDIS. 
Color more dull than in male, much wanting in the pinkish tint, more inclined to oohraceous or brown ; 
markings same as in that sex. 
Habitat. Canada, and the United States generally as far westward as the Mississippi. 
The larva is 2 1 inches long ; has a pointed head ; is of a pale green color with lateral stripes and gran- 
ulated with white; caudal horn much granulated. In Abbot & Smith’s work t. 29, the larva is ferruginous 
in color, but the text further states that “the Caterpillar is sometimes green.” It feeds on the black walnut 
(Juglans Nigra,) and Hickory (Carya Alba,) also on the Iron Wood (Ostrya Virginica,) on which latter 
Mr. Lintner found the mature larvae.* Mr. Packard’s assertion that it “li ves on the Wild Cherry” is erroneous, t 
The pupa is brown and has the three terminal segments flattened beneath. 
This is by no means a common insect though rather wide spread. There is some variation in the color 
of the female, some examples being of a decided ochrey or brownish shade, whilst others approximate more to 
the flesh color of the male. This in common with the other Smerinthi varies much in size in different examples. 
In Abbot’s plate the colorist performed some funny work, in that the primaries in both sexes are colored 
pretty close to nature but the secondaries are painted yellow, and the worst feature of this is that in the text 
this difference is mentioned as a fact, and brought directly to notice by the author making some remarks in 
connection with this and a somewhat analagous European species,! it will be seen by my figs. 12, 13, as well 
as by the description, that this has no foundation, except in the fancy of the person who colored the plates, who 
doubtless imagined that a little variety introduced would improve the natural plain appearance of the insect. 
I have commenced the Catalogue which heads this paper with this species, believing the grounds for 
retaining it in a separate genus to be entirely insufficient. 
SMERINTHUS PALLENS. Nov. Sr. 
! PLATE VH, FIG. 14 $.) 
Female. Expands 2§ inches. 
Same form as Juglandis; wings a little broader in proportion than in that species. 
Upper surface, uniformly ochraccous ; primaries with two light brown sub-basal lines ; two other lines, 
parallel with the exterior margin, traverse the wing from inner margin to costa, near and at which they 
curve inwardly towards the base ; on the disc, between the 1st and 2nd median nervules, is a very faint greyish 
shade. Secondaries have two pale brown median lines which follow the curve of the outer margin, there are' 
also faint indications of a third line nearer the base. 
Under surface, same color and markings as above, perhaps a possible shade paler, Avith the exception of 
the sub-basal lines of primaries which are here wanting; emarginations whitish. 
Described from a unique 9 example received from Texas near the Mexican boundary. I would like to 
sav something further regarding this rather curious insect, but as the above embodies all I really know con- 
cerning it, I will spare my readers, and not attempt to make mere verbiage supply the paucity of fact.

(PLATE VII, FIG. I rf , 2 ?.) 
Male. Expands 2J to 2| inches. 
Head and body fawn colored ; a broad dorsal thoracic patch widest near the abdomen, narrow in the 
middle and terminating in a line on the head ; a dorsal stripe on the abdomen.

t“ Mr._ Abbot very justly remarks the affinity between tills and Sphinx Populi, the Antennae which in the male are also, in a degree pectinated ; 
l ut there is not much affinity in the markings of the wings, nor is there so great a difference of hue between the fore and hind wings of S. Populi as 
in that now before us. ” Abbot & Sm. Ins. Ga., Vol. I, p. 57, (1797.)
