350 GROTE AND ROBINSON. 



squamation greyish. AbdorLen cinereous, thickly irrorate, especially 

 beneath, where the segments are indicated by whitish scales. Anal 

 hairs blackish. 



Anterior wings blackish-brown, silky, with a faint purplish shade; 

 transverse lines geminate, with broad pale included shades. A basal 

 half-line, dentate, distinctly raai-gined. Transverse anterior line per- 

 pendicular, distinct, forming an M-shaped mark opposite the orbicular, 

 thence running straightly downwards, forming a slight curve to inter- 

 nal nervure, below which it forms a single outward projection I'eturn- 

 ing to the margin. It is geminate, distinctly limited outwardly by a 

 narrow black line; the inner line is wanting or nearly so. Median 

 space paler than the wing elsewhere, but obscured centi-ally by a very 

 diffuse dark transverse median shade. Orbicular spot rounded, pale, 

 with a narrow black annulus, and obscured outwardly by the median 

 shade. The space between the spots on the cell is darker than else- 

 where. The usual accessory claviform spot below the median nervure 

 resting on the transverse anterior line. Reniform large, pale, of the 

 normal shape, but so approximate to the transverse posterior line that 

 it appears to be fused with it superiorly and outwardly, where its black 

 annulus is obsoletely continued. Transverse posterior line distiifctly 

 edged on costa, its inception taking place at a point within the reniform, 

 outside of which it is outwardly projected; opposite the middle of the 

 reniform it bends slightly inwardly, thus conforming to the shape of 

 the spot; it is then outwardly and roundedly projected, and runs thence 

 downwardly and slightly inwardly obliquely to internal margin. It is 

 geminate, its inner line unevenly lunulate and distinct, its outer even 

 and obsolete. Beyond the transverse posterior line the wing is very 

 dark and glossy; the irregular subterminal line is very narrow and 

 pale; between the transverse posterior line and the subterminal, are 

 three minute pale costal dots. On external margin, a very narrow 

 inconspicuous, broken black line ; fringes a little paler than the wing, 

 with a basal darker shade. Secondaries griseous, glossy, gradually be- 

 coming darker towards external margin, without line or discal spot 

 Fringes white or whitish, prominently contrasting with the wing and 

 showing a faint darker basal line.
