COSSUS (?) rOLYGRAPHA, U. Sp. 



Female, 28-35 mm. Head and j^alpi light-fuscous, mixed with 

 whitish and black, antennae dark-fuscous, slenderly annulated 

 with white, base ochreous, thorax ashy-grey-whitish, patagia with 

 well-defined black edge. A similar band on posterior portion of 

 thorax, divided in middle by a whitish spot. Abdomen with two 

 basal segments ochreous grey, third somewhat rufous, rest 

 fuscous grey, margins whitish, crests whitish. Legs light-fuscous, 

 posterior pair darker, ringed with whitish at apex of joints. 

 Forewings elongate oblong, costa arched at base, hindmargin 

 almost straight, slightly oblique, light-fuscous, irrorated with 

 round patches of white and black scales. Veins before middle 

 outlined in blackish, a white suffusion from middle of base to 

 before middle of wing, posteriorly bent down along vein 1 to 

 two-thirds, thence continued suffusedly (in one specimen very 

 indistinctly) to costa about two-thirds, suff'used at anal angle ; 

 twelve or fifteen blackish spots along costa, from each of which 

 proceeds an interrupted blackish waved line towards inner margin; 

 more distinct in middle of disc, where there are some ferruginous 

 scales suftused ; a small white spot on submedian fold, a fan- 

 shaped patch from costa before apex to vein 1, where it is edged 

 by a black line, and on costa with three elongate black marks. 

 In the patch the veins are thickly outlined with white, and a few 

 black scales at base ; cilia light-fuscous, sprinkled with blackish, 

 at extremities of veins with elongate white streaks, continued to 

 tips, giving the appearance of black and white lines. Hindwings 

 fuscous at base, with ochreous hairs Cilia whitish, base ochreous 

 tinged. 



Mitcham and Parkside in May, two female specimens. With- 

 out the male it is uncertain as to genus ; perhaps a new one will 

 be required to receive it. It hardly seems a Cossus, as generally 

 understood.
