bercles, with whitish tubercles for rest of length, and suggestive of 
amyntor’s central, dorsal, serrate line; these two lines fade out on the 
10th segment. A lateral, whitish line from 4th to 11th segment, across 
which, dorso-caudad, the 7 oblique bands barely pass and abruptly 
end. Seven oblique, lateral stripes, each green cephalad, yellowish 
caudad; 7th 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 franckiui (this is in Fig. 1, Plate II), and on May 
IIth 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
