 middle of the cell and a similar discocellular excurved bar ; generally a narrow 

 incurved slightly apparent speckled inner cell bar is also present ; beyond are three 

 pale greyish-black transverse bands, the inner band narrow, recurved, very sinuous, 

 and more or less speckled with white scales, and also, occasionally, its anterior end 

 is centred with a few red scales, the middle band is less sinuous and broader, the
