To this last I give the name m/ulala ah.; it differs from the two typical 

 specimens in having the whole ground-colour above pale oclireous like the underside, 

 without the darker tints; but as against this the .sp.ice between the two double 

 lines is filled up with dark fuscous, forming two prominent bands, the outer continued 

 to below apex as the edge of the brown marginal patch, and connected with inner by 

 the wedge-shaped mark and cell-lilolcli ; hindwiugs with the postmedian Viand oidy.
