72 [August 



Abdomen, paler ttan thorax, with lighter lateral scales surrounded with 

 black, forming more complete maculations towards the base ; beneath 

 paler, somewhat brownish cinereous. Legs clothed with yellowish oli- 

 vaceous scales; tarsi annulate; posterior tibise strongly spurred. Max- 

 illae moderate. 



Resembles Sphinx Pamphilim, Cram. PI. 394, fig. E. ; if we allow 

 great latitude to the figure, we may perhaps regard it as the species 

 intended. Cramer's figure has the posterior wings nearly all black, 

 while the general color is much as in S. afflicta. The course of the 

 transverse lines on anterior wings, diiFers in detail. 



One male specimen. Exp. 3.60 inches. Length of body. 1.60 inch.

In the shape of the wings this species somewhat nearly resembles 

 *S^. repentirius, while the head and eyes are larger, more salient, and 

 the general coloration very difi"erent and peculiar. Independent of 

 these the ornamentation, though displaying a somewhat similar pat- 

 tern, is quite distinct. 



The different species I have here finally alluded to, and already 

 vaguely characterized as cinereous, roughly-scaled species of Sphinx, 

 will need a generic revision ; provisionally, these are better referred to 

 the typical genus of the family.

The external margin of the anterior wings is entire, not denticulated. 

 Cramer's figure is quite recognizable, his best in the genus perhaps, 

 while the specific name is liable to some confusion, since there is ano- 

 ther species called Cacus by the same author, Plate 46, fig. E. {Dilo- 

 phonofa Cacus Burm.) belonging to the same genus, though but dis- 

 tantly resembling the present species.
