Male. Dark umber-brown : forewing with a transverse subbasal indistinct 

 blackish pale-bordered undulated line, a medial black slightly angulated line extending 

 outward from beyond middle of the costa, which is convexly angled in crossing the 

 discocellular area beyond the cell, and is then continued vei'y obliquely to near base 

 of the posterior margin, the upper portion of the line forming the outer border of 

 the ocellus, which is completed on the inner side by a broad ferruginous-brown pale- 

 bordered black-lined lunate mark with lower bilobed end, the lower end being also 

 traversed with a slender blue-white line, and streaked with black in front ; bordering 

 the medial line the area is broadly pale brownish-ochreous, thus forming a prominent 

 elbowed band, the upper end of which is almost white ; this is followed by a transverse 

 discal slender pale black-bordered lunular undulated line, the broad outer border 

 being traversed by a sulimarginal irregular-angulated zigzag series of whitish- 

 bordered black recurved streaks, and a prominent dentate spot before the apex, the 

 outer margin of the wing being pale umber-brown : hindwing with the broad pale 

 brownish-ochreous band crossing near the base, followed by a pale-bordered black 

 line, beyond which is the discal pale-bordered black line, and the submargiual 

 irregular pale-bordered angulated zigzag black line, the broad outer margin of the 

 wing being pale umber-brown ; outer edges of the discal and submargiual lines 

 fringed with greyish hairy scales. Thorax, head, palpi, and legs above umber-brown ; 

 abdomen brownish-ochreous, the base pale cinereous. 



Female. Greyer brown, sometimes of a more ochreous-brown ; marked as in 

 male, except that the forewing has the medial elbowed line narrowly bordered with 

 white below the angle, the discal line being also prominently white and denticulated ; 

 the submarginal line and apical spot also whiter. On the hindwing the subbasal band 

 and bordering line is whitish, the discal line very prominently denticulated with 

 purplish -white, and the submarginal irregular zigzag line broadly fringed with 

 purplish-grey hairy scales. Thorax, head, palpi, and legs above greyish-brown, 

 abdomen paler, the base greyish-white. 



Expanse 3^ to 4 inches.
