Pupa similar to that of I'xcuecatxt. 



Ilfih. Canada to N. York and Pennsylvania; a rare species. 



The liybrid between this species and Sphinx ocellata was olitained by Mr. 

 Pix and described by Nenmoegen, I.e. We have three specimens of it, which show 

 a mixture of tiie characters o{ asti/litu and ocfllatu. The thorn at the end of the 

 anterior tibia is present, but is not so long as in ocellata. The specimens of Mr. 

 Pix's brood were, apparently, all males. The eye-])atch of this hybrid is of special 

 interest (see above under S. jamaicensis).

Close to Sphinx, from which it does not differ very obviously in structure. 

 However, the two species, popali and amurensis, form a separate branch. There- 

 fore we do not besitate to treat them as generically distinct from the eyed Sphinx. 



(J?. Anterior tibia without apical thorn. Hindtibia witii one pair of short 

 spurs. Tibiae not spinose. Piilvillns and paronychium present. Retinaculum 

 absent; frenulum also absent in c?, but vestigial in ? {\\\ Sphinx \\\& frenulum of 

 tiie $ is present, but reduced in length). Hindwing broad, costal angle broadly 

 rounded, distal margin obliquely sinuate between C and S(-'-, produced into a 

 sinuate lobe at >S(_"- and R', this lobe more prominent than the teeth at the other 

 veins. Abdominal tergites sjiiny all over, the spines weak, very dense at and near 

 the apical edges, covered witii long scales. Tiiorax unicolorous ; liiiidwing witlidut 

 eye-spot. 



c?. Antennal segments feebly dilated laterad at the upjier edge of the side- 

 grooves ; ciliae long. Harpe (PI. XXXIV. f. 24) with two rounded lobes distally, 

 both lobes visible in a ventral view of the end of the abdomen after the removal 

 of some scales, projecting mesiad beyond the ventral edge of the clasper. Penis 

 with spines at the edge of the sheath as well as upon the membrane of the duct 

 (PI. XXIX. f. 40). 



?. Vaginal jilate without processes ; the proximal edge of the vaginal cavity 

 somewhat raised, wrinkled, more strongly cliitinised than the rest of the vaginal 

 area, mesially sinuate or emarginate. 



Early stages essentially as in Sphinx, but })npa not glossy. — Food-plants : 

 Populus, Salix.
