146 LEPIDOPTERA. 



Antennae moderately long, in the male strongly and regu- 

 larly pectinated,' pale brown, shaft white. Palpi very large, 

 standing obliquely upwards in front of the head, broadly and 

 densely clothed with scales and regularly crenulated along 

 the front edge, whitish drab, almost hiding the rather darker 

 head ; thorax broad and squared, with large uplifted shoulder 

 lappets, and the middle portion crested with long upright 

 scales, brownish-drab ; abdomen long and tapering, not' 

 stout, whitish-drab, having a very long forked anal tuf fc, and 

 small tufts on the back of the basal segments. Fore wings 

 rather long and narrow ; costal margin very straight ; apex 

 angulated and rather pointed ; hind margin extremely full 

 and rounded, regularly scalloped throughout, but more 

 deeply so at the anal angle ; dorsal margin singularly formed, 

 having a large projecting tooth a short distance from the 

 anal angle, and a far larger one, edged with projecting scales, 

 nearer the base. Colour pale bufE with numerous blackish 

 dashes on the nervures, and slender longitudinal brownish 

 lines and shades between them ; in the middle is an oblique 

 straight cloudy brown stripe from the larger prominent tuft 

 to the costa beyond the middle ; before the larger prominent 

 tuft a slender curved line indicates the usual first line and 

 proceeds in dots across the wing ; beyond the central stripe a 

 sort of normal second line, commencing by a dark streak 

 before the small prominent, is represented by pairs of dots on 

 the nervures and short shades between them ; edging of large 

 prominent tuft blackish ; along the hind margin is a row of 

 brownish lunules fitting into the marginal scallops ; cilia 

 whitish-buff, interrupted at the ends of the lunules. Hind 

 wings slightly rounded, acutely so at the apex, whitish-grey, 

 whiter at the base, with a grey cloud along the hind margin, 

 preceded by a pale line and a series of dark grey dashes on 

 nervures ; cilia white. 



Female with antennae shortly pectinated, palpi equally long 

 but narrower ; abdomen much stouter, but with only a short 

 blunt anal tuft ; fore wings longer and broader, more pointed,
