In form this insect resembles Arsenura erythrinm^ Merian, 

 and to some extent in coloration it is like Saturnia pandora 

 of Klug. I have named this fine species after its captor 

 Mr. Kichardson.

 yellowish brown : secondaries pale cream-colour, darkest at 

 the base and along the inner margin. The underside of both 

 wings yellowish white, almost yellow at the base of the
