placed a short distance apart ; claviform stigma very broad, 

 wholly deep black ; costa spotted with black and yellowish- 

 white ; space between the upper stigmata often black, that 

 below them clouded with white ; extreme hind margin edged 

 by a series of deep black crescents, each embraced by a 

 yellowish-white crescent, from the junctions of which pale 

 dashes run to the tips of the cilia, the spaces between these 

 dashes brown, divided by a black line. Hind wings not 

 large, rounded, dull greyish-brown, shading ofE to whitish- 

 umbreous from the middle to the base ; nervures darker 

 central spot faintly perceptible as a streak ; cilia pale yellow 

 at the base, barred with a brown line and tipped with white. 

 Female quite similar, except that its antennge are wholly 

 threadlike, and its abdomen is stouter and tapered off at the 

 extremity to a long pointed sheath, which sometimes covers 

 the ovipositor, though in other examples the latter is con- 

 siderably protruded. 



Underside of the fore wings dull greyish-brown, rather 

 paler toward the dorsal margin ; costa toward the apex 

 dotted with pale yellow ; reniform stigma indicated by a 

 black streak and followed by a faint cloudy darker brown 

 transverse stripe ; hind wings pale smoky-brown, more 

 whitish toward the base, but dusted with darker brown ; 

 central spot a small brown streak ; beyond it are faint indi- 

 cations of two darker brown transverse bands. Body and 

 legs dull brown, the tibia? barred in front with yellowish- 

 white. 



Usually not variable, or only slightly so in the intensity 

 of the dark clouding and markings, but in the collection of 

 Mr. Sydney Webb is a specimen having the pale colouring 

 below the stigmata increased into a sort of dusky-white 

 central bar, and another, a most singular aberration, in which 

 the margins of the stigmata and the subterminal line are 

 broadened into yellow-white clouds, occupying a considerable 

 portion of the fore wing. A specimen exhibited at a meeting 

 of the South London Entomological Society, in September
