I70 LEPIDOPTERA. 



behind ; costa arched at the base, then straight ; apex sud- 

 denly rounded ; hind margin rounded and very full at the 

 anal angle, not very oblique ; dorsal margin almost straight. 

 Colour pale reddish-grey or smoky-grey, with two indistinct, 

 nearly straight, parallel whitish lines, edged with dark grey 

 before the middle, as in the last species ; but rather oblique, 

 leaning inward toward the costa. In the middle of the wing 

 is one-half of a similar line from the median nervure to the 

 dorsal margin. From the end of the discal cell the space to 

 the apex is occupied by a large dark blotch of greyish-choco- 

 late, changing to smoky-grey in its hinder area ; the lower 

 edge of this blotch hollowed, but curving downward as it 

 approaches the hind margin. In this large blotch, cutting 

 it near its origin, is a slender, interrupted, undulating white 

 stripe, continued across the rest of the wing as the faintest 

 possible whitish thread, and evidently recognisable as a 

 normal second line. Outside the white stripe are two black 

 spots on the apical blotch, and below it an elongated black 

 spot placed transversely to the wing, followed by a smaller 

 spot ; hind margin edged with black dashes ; cilia smoky- 

 grey. Hind wings smoky-brown or smoky-grey ; nervures 

 slightly darker. Antennae of the female very shortly pecti- 

 nated ; body stouter ; otherwise similar. 



Underside of the fore wings dull grey or brown, with a 

 slightly indicated whitish transverse line beyond the middle ; 

 hind wings brownish-white or pale grey, with a slender brown 

 transverse stripe and brownish nervures ; body and legs dull 

 brown or grey. 



Only variable in depth of colour. 



On the wing in May, in a second generation in July, and 

 in confinement a third has been obtained in September. 



Larva.^ — Head rather narrow, with the lobes pointed in 

 front ; body even in thickness, flattened beneath. On the 

 back of the fifth segment is a large and conspicuous knob 

 pr tubercle, rounded above, dull pink or red-brown^ sur-
