 (individually variable) ; SC 2 ending close to apex of wing, 

 sometimes continued along edge and joining SC 4 at apex ; 

 SC 5 from SC 4 at about one-third the way from cell to apex ; 

 R 1 from upper angle of cell or shortly stalked with SC 4, 5 ; 

 R 2 from below centre of apex of cell, but always well above 

 angle ; M 1 before angle of cell, M 2 in or near middle of cell ; 

 SM 1 absent, SM 2 forming fork at base with SM 2 ; upper angle 

 of cell more distal than lower angle. Hind wing : C and SC 2
