''Chonala masoni'', the Chumbi wall, is a species of
satyrine butterfly found in Bhutan, China and north-eastern India.
The species is named the Chumbi wall after the
Chumbi Valley where it was "presumed" to have been collected by a native collector and passed on to
Henry John Elwes in 1881 when he visited
Sikkim with
Frederick DuCane Godman. It was originally described as a species in the genus ''Debis''.
