 ground-colour— ab. pallida-virgata, n. ab. 



The females are still more difficult to classify. Roughly, they 

 divide into two colour groups, grey and reddish-grey, with almost 

 as much variation in the character of the transverse lines as in the 

 males : 



Ground-colour grey without any reddish tint.
