488 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 



rare on low white birch shrubs. I have found the egg and young larva 

 on the willow at Brunswick in July, but have not reared an individual 

 through all the stages from the first.* 



The following notes are by Mrs. Anna K. Dimmock in Psyche, iv, p. 



282: 



Smerinthus excwcatus Abb. and Smith (Nat. Hist. Lepid. Ins. Ga., 1797, v. 1, p. 49, 

 pi. 25). Harris (Ainer. Journ. Sci. and Arts, July 1839, [s. i], v. 36, p. 290) gives a 

 brief description of larva and imago of this species, which he states to feed upon 

 ap])\e and Bosa Carolina ; Morris (Syn. Lepid. N. A., 1862, p. 209) gives Harris's de- 

 ecription of the larva, with slight addition, and adds a description of the yonng larva 

 and of what he supposed to be the egg— really, however, the egg of Attacus polyphe- 

 nuts. Harris (Treatise on Ins. Injur. Veg., 1862, p. 327-328) describes and figures the 

 imago. Lintner (Proc. Entom. Soc. Phil., 1864, v. 3, p. 666) describes the larva 

 without knowing the species, and later (Entom. Contrib., No. 2, 1873, p. 23) he gives 

 its name, and states that the larva described by him (Proc. Entom. Soc. Phil., 1864, 

 V. 3, p. 665) as S. excwcatus was in reality S. geminatus. Sanborn (Can. Entom., Jan. 



slightly reddish ; mandibles black. Body of a uniform pale pea-green color, a little 

 more vivid than the under side of the birch leaves. The surface of the skin rough with 

 small conical papillae. Seven lateral stripes pale yellow, moderately broad, begin- 

 ning in front of each abdominal spiracle on front edge of the segment and extending 

 upon the back of the succeeding segment. The last yellowish stripe extends to 

 the base of the horn or eighth segment, which is moderately stout and long. Neither 

 the caudal horn nor yellowish lateral stripes are stained with lilac. The spiracles 

 are black, with a central white line. The forefeet are rose-red. The abdominal 

 legs concolorous with the body, which is of the same pale yellowish green above and 

 below ; the hooks are dark. Length 50"™.
