obscure thin white line running from the white stripe 

 along the transverse suture, reaching half-way to the 

 wing. The ground colour of the thorax is bright slate- 

 grey, and is much suffused with brown and black, form- 

 ing no constant pattern other than that described above, 

 but the area just above, and the basal area of the scutellum, 

 is always free from black markings; at most there is a 

 slight trace of brown on the scutelliun (in this it differs 

 fi-om movtanux, which has these areas, either one or both, 

 marked with black). Wings spotted, the fork of the cubi- 

 tal vein often with a recurrent veinlet (appendix). 



Female. Similar to male, eyes separate, front brown, 

 black or dark greyish.
