54 SMERINTHUS JUGLANDIS. 



Color more dull than in male, nmcli wanting in the jjinkisli tint, more inclined to ochraceous 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| inehes long; has a pointetl head ; is of a pale green color with lateral stripes and gran- 

 nlated 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. Lintncr found the mature larvae.'" Mr. Packard's assertion that it "lives 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 oehrey 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, J it will be seen by my figs. 1'2, 13, as well 

 as by the description, that this has no Ibunilation, except in the fancy of the jjcrson 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 gronnds for 

 retaining it in a separate genus to be entirely insufficient.

PLATE VII, FIG. 14 S.) 



FEiiAi.E. Expands 2^ inches. 



Same form as .Juglandis ; wings a little broader in proportion than in that species. 



I; pper surface, uniformly ochraceous ; 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 uervules, 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, pei'haps a possible shade paler, witii the exee|>tion of 

 the sub-basal lines of primaries which are here wanting; emarginatious whitish. 



Described from a unique + example received from Texas near the Mexican boundary. I would like to 

 say 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.
