wedge, and between it and the reniform a black rhomboid 

 spot ; claviform stigma very obscure, but long and pointed, 

 merely indicated by pale marginal lines, one of which runs 

 back to the base of the wing ; hind marginal region clouded 

 with blackish-brown, and the extreme edge indicated by long, 

 slender, black lunules ; cilia pale yellowish-brown, strongly 

 barred and dashed with dark brown ; hind wings rounded, 

 white dusted with brown and having an ill-defined and 

 sometimes incomplete cloudy smoky-brown transverse band 

 before the hind margin ; cilia white. Female decidedly 

 larger, with simple antennas, very stout abdomen, and more 

 ample fore wings, of which the colour is usually a more dull 

 umbreous ; hind wings smoky-brown, rather paler toward the 

 base and with faintly whitish nervures. 



Underside of the fore wings smoky-brown with paler 

 nervures ; reniform stigma dusky-white, containing two 

 black streaks ; dorsal margin dirty-white. Hind wings 

 white broadly dusted with brown along the costal region and 

 the apex, less so on the nervures and hind margin ; body 

 pale drab ; legs umbreous. 



Hardly ever variable except in the colour of the hind 

 wings in the male, the smoky-brown transverse band near 

 the margin being in some individuals dark but narrow, 

 sharply but irregularly defined behind, and even broken up 

 by the white ground ; in others cloudy and extended so as 

 to shade nearly one-half of the surface. 



On the wing at the end of August and September. 



Lakva stout, nearly cylindrical, thickest in the middle, 

 tapering a little toward each end ; head full and rounded, 

 brown ; body shining, even brilliantly glossy, deep greenish- 

 brown or smoky-brown ; a darker semicircular plate on the 

 second segment, showing indications of the longitudinal 

 stripes, five in number ; dorsal and subdorsal stripes pale 

 pinkish-grey, greyish-ochreous, or pale brown, widening 

 a little in the middle of the body and then gradually
