 imperfect smoky-brown marginal band ; central spot 

 rounded, black ; legs blue-black in front, barred with 

 yellowish ; leg tufts and body smoky-brown. 



Usually very constant in colour and marking; but in the

 specimen, having the fore wings suffused with hoary grey. 



Abroad a recurrent variety is known, in which the reni- 

 form stigma, instead of being white, is suffused with black 

 or yellowish black. This is found in Turkey and apparently

 each side of the mouth is a whitish projection ; body pale 

 green reticulated with darker; dorsal and spiracular lines 

 whitish, minutely edged with dark grey ; subdorsal lines 

 dark grey, threadlike ; from the fifth to the twelfth segments 

 the subdorsal lines are connected by semicircular dark green

 green, edged laterally with white. On the sides is a row 

 of green dashes which include the white spiracles and
