 Judging from the description alone, I rather doubt this being a true Ambulyx.

Basiana? canescens, Walker, Lep. Het., Suppl. i. p. 38 (1864).

Unquestionably an Ambulyx, apparently allied to A. liturata, but without the dark 

 spots at base of primaries.

Allied to A. gannascus, but with the hind wings golden yellow. It comes in well 

 between the A. strigilis and A. gannascus groups.
