bercles, with whitish tubercles for rest of length, and suggestive of 

 amyntor's central, dorsal, serrate line ; these two lines fade out on the 

 roth segment. A lateral, whitish line from 4th to nth segment, across 

 which, dorso-caudad, the / oblique bands barely pass and abruptly 

 end. Seven oblique, lateral stripes, each green cephalad, yellowish 

 caudad ; /th most prominent and ending at base of caudal horn. Dorsal 

 anal flap edged with yellow. Caudal horn apple-green, minutely 

 punctulated with same color. Head apple-green, with two faint yellow 

 lines. Thoracic legs pink. Stigmata cream-pink edged with brown. 

 Three or four punctules over each proleg, parallel to oblique, lateral 

 bands. Jaws black. 



The pupa is almost identical in color, size, and shape with 

 that of chersis, with the short, free "tongue case" of the lat- 

 ter, which is 3.5 mm. long on its under free surface. 



The proof of an anticipated identity was yielded on May 

 3, 1911, when the surface pupa yielded a perfect and beautiful 

 male Sphinx franckii (this is in Fig. i, Plate II), and on May 

 nth one of the subterranean pupae disclosed a perfect fe- 

 male. (Fig. 2). The importance of testing the specific valid- 

 ity of this supposed hybrid sphinx, as well as the desire to 

 obtain more specimens, urged upon me the duty of tying out 

 this female for egg results, but the cold spring had so retarded 

 everything that no hawk-moths had been seen on the wing 

 as yet, and moreover, the ash trees were not in foliage, and the 

 lilac barely out ; with reluctance therefore, I killed the female 

 also, and thus graced my collection with a perfect pair, the 

 first ever bred, and the female, the only one in existence, as far 

 as I know, of this rare species (?) 



My male agrees fairly well with the colored figure given by 

 Rothschild and Jordan, in their Monograph of the Sphingidae 

 in Wytsman's "Genera Insectorum," though the black outer 

 border of hind wings is even and continuous in my specimen, 

 and not sagittate as in their figure, and the fore costal area is 

 more evenly grey. Neumogen's original description of the 

 then unique type, a male, in Ent. News, Vol. IV., p. 133, agrees 

 fairly well with my specimen, though mine is 2 mm. longer 

 than the type, in alar expanse. 



The female is larger than the male, being 118 mm. in alar
