Differs from Diludia, Pseudosphinx, and allies in its narrower wings, the (in the type) 
more incuryed external angle, more arched costa, and longer outer margin of primaries 
and the somewhat longer head.

Macrosila incisa, Walker, Lep. Het. vil. p. 205. no. 11 (1856). 
3, Rio Janeiro (Stevens). Type, B.M. 
The general coloration of the wings is that of Diludia; but the primaries have an 
oblique diffused brown bar across them from the costa to the outer margin; the thorax 
is grey, with a pitchy streak on each side; the abdomen above dark grey, a black streak 
on each side, and an ochreous spot on the four basal segments; wings below light 
chocolate-brown, whitish at base; body whitish testaceous. 
2. MACROSILA HANNIBAL. 
Sphinx hannibal, Cramer, Pap. Exot. iii. 1, p. 39, pl. 216. fig. A (1782). 
Phlegethontius hannibal, Hiibner, Verz. bek. Schmett. p. 140. no. 1502 (1816). 
Brazil (Stevens). B.M. 
Cramer's figure gives an entirely false notion of the form of the wings, the primaries 
being more elongated than in Sphinx kalmiew; they are not incurved above external 
angle as in the type of the genus; and the coloration is more like Sphina lucetius of 
Cramer. 
* Characterized by its slightly smaller head, coarser antenne, and the entire margin to the wings; the style 
of coloration is also not quite the same.
