Hind wing cinnamon -red with a blackish submarginal band. 

 Abdomen with black stigma-dots. Expanse : $ 64 mm. y 

 ? 89-25 mm. 



<$. Tenth tergite (fig. 57 A) broad, constricted at base and 

 in middle, above longitudinally impressed mesially, sides 

 convex, apex divided into two short pointed lobes ; sternite 

 (fig. 57 B) small, obtusely triangular, sides obliquely and

Imago. — " ^$. Differs from Smerinthulus in the hind wing 

 being produced front ad near apex into a rounded lobe, the 

 costal margin more or less sinuate proximally of this lobe, 

 vein C almost following the curve of the lobe, not straight
