 which the margin is slightly excised ; the subcostal space is occupied by 

 numerous small black spots (interspersed with larger ones) following 

 the transA'crse nervules ; between the fourth and fifth principal longi- 

 tudinal veins the transverse oblique nervules are broadly margined 

 with black ; a large irregular blackish spot beyond the end of the 

 postcosta on the dorsal margin (at the base of the oblique branch of
