54 SMERINTHUS JUGLANDIS. 



Color more iliiU than iu male, much wanting in the i)lnki:<h tint, more inclined to ocliraceous or brown ; 

 markings same as in that sex. 



Habitat. Canada, and the United .State.-; generally as far westward as the Mississippi. 



The larva is 2[ inches long; has a pointed head ; is of a pale green color with lateral stripes and grau- 

 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 >>igra,) and Hickory (Caiya Alba,) also on the Iron Wood (Ostrya Yirginica,) on which latter 

 ,Mr. Lintiicr found tiie mature larvae.* Mr. Packard's assertion that it''livcs on the Wild Cherry" is erroneous."!" 



The pupa is brown and has the three teuninal 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 i)cing of a decided ochrcy or brownish shade, whilst others approximate more to 

 the flesh color of the male. This in common with the other Smeriuthi varies much in size in different examples. 



In Abbot's plate the colorist jjcrformed some funny work, in that the primaries in both sexes arc colored 

 prettv close to nature but the secondaries arc painted yellow, and the worst feature of this is that iu the te.xt 

 this difference is mentioned as a fact, and brf)Ught directly to notice by the author making some remarks in 

 connection with this and a somewhat analagous JCuropean species,| it will be seen by my flgs. 12, 13, as well 

 as by the description, that this has no i(>undation, except in the foncy of the ])erson who colored the plates, wiio 

 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.

(PLATE Vir, FIG. 14 ?.) 



Fkmai-K. Exjiands 2j: inches. 



.Same (i)rm as Juglandis ; wings a little broader in i)roportion tiian in that species. 



I'pper surlaec, uniforndy 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 

 :dso faint iiulications of a third line nearer the base. 



Under surface, same color and markings as above, perhaps a j)ossiblc shade paler, with the exception of 

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



Described from a uni(pic ? example received from Texas near the Mexican boundary. 1 would like to 

 Siiy 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.

;•• Mr. Abbot very justly remarks the afflnlty between this and Sphinx Populi, the Antennae which in the male are alM, in a degree pectinated; 

 1 111 there is not much affinity In the markings of the wings, nor is there so great a difference ot hue between the fore and hind wings of &. Populi as
