68 CLARK — NEW SPHINGIDAE Paya 
Hind wing above: Basally yellow-brown. A large, black, circular spot 
above the inner margin; a band of submarginal spots bordered inwardly 
by a pink line; spots distinct toward anal angle and continued obscurely 
to inner margin. Anal angle slightly pink. 
Fore wing beneath: An irregular gray marginal distal band, widest on 
R2. Two distinct postmedian lines semi-parallel to distal margin, and 
turning basad on R2 as they approach the costal margin; the outer line 
lunulate and touching the distal band. 
Hind wing beneath: A similar gray marginal distal band, and two dis- 
tinct lines semi-parallel to the distal margin, and turning basad as on the 
fore wing. 
This form appears to belong, territorially, to a group of Sphingidae in- 
cluding Protambulyx carteri, Isoparce cupressi, Lapara halicarniae, Iso- 
gramma hageni, and Arctonotus vega, which occur along the Gulf States of 
the United States and west into Texas and New Mexico, and, so far as 
known, neither north nor south of this belt. 
Structurally, it les between pandorus, licaon and elisa, is nearest to 
licaon, and is smaller than any other Pholus found in continental North 
America. The upper side of both fore and hind wings, is of the color of 
licaon, while the outer margin of the fore wing shows as much convexity 
as pandorus, more than licaon, and less than elisa. The dark subbasal 
patch at the inner margin of the fore wing is continuous with the rhombi- 
form median patch, and is slightly lighter in color; in these respects inter- 
media differs from licaon and approaches pandorus. The outer edge of this 
median patch curves basad as it approaches the inner margin, differing in 
this respect from all three forms mentioned above. The postdiscal lines 
on the fore wing are nearly parallel to the distal margin, and thus reach 
the costal edge nearer the apex of the wing than in pandorus, and more 
nearly as in licaon. The tone of both the fore and the hind wing, beneath 
— dark brown with a distinct pink tinge, very marked on the hind wing — 
is in marked contrast with the light brown under side of licaon, the green of 
pandorus, and the dark brown of elisa which is unrelieved by any touch of 
pink. The pink tinge at the anal angle of the hind wing above is less 
marked than in pandorus, while the black submarginal spots are heavier 
than in either elisa or pandorus, and are as large as in licaon. 
While the differences separating this subspecies from the 
others mentioned, are not many, they are distinct, and the 
form has a character of its own.
