The antenne of the male of this species are rather less strongly pectinated than in 
M. quercis.

Mr. Walker says that this species possesses the “structure of S. tiliw.” The second- 
aries, however, differ slightly; and the costa of primaries is not quite so much arched. 
In the outline of the outer margin it agrees better with JZ. quercis. 
Genus 3. Potyprycuus, Hiibner (restricted). 
Polyptychus, Hiibner, Verz. bek. Schmett. p. 141. gen. 2 (1816).

Sphinx dentata, Cramer, Pap. Exot. ii. p. 42, pl. 125. fig. G (1779). 
1 Fasily distinguished from Zaothoé by the form of the wings, the outer margin of secondaries deeply exca- 
yated below the apex, and the secondaries narrow and not denticulated. The type is M. tilie.
