Hab, Xieng Khouang, March 18. Described from three 
females. 
The fuscous cloud at the apex of the fore wing is very 
variable in extent, and in one specimen is wholly absent. 
The species bears a strong superficial resemblance to the 
Chinese species Athermantus imperialis, Sm., which belongs 
to the Argine. 
Subfamily Arermz.
