NOVITATES ZOOLOGICAE XXII. 1915. 151 



Underside pale grey-brown with deep brown fringes ; median and onter lines 

 darker ; the outer line of forewiug marked with a pale spot on costa ; all the veins 

 marked with sparse pale scales. 



Head and thorax brown speckled with pale ; patagia with a slight ahdy gloss ; 

 abdomen olive brown ; tips of the anal scales pale ochreous ; pectns and legs dark 

 brown ; the tarsi with pale joints ; the spurs with pale tips. 



Expanse of wings : 66 mm. 



1 <S from the Upper Setekwa River, August 1910, and 1 ? from near the 

 Oetakwa River, Snow Mts., Dutch New Guinea, October to December 1910 

 (A. S. Meek). 



In the ab. perfasa ab. nov. the median area also is pnrplish slate-colour, its 

 outer costal half the darkest. Of this form there are 1 c? and 2 ? ? in the Tring 

 Musenm, taken along with the type J', on the Upper Setekwa River in August 

 1910, and 1 ? from the Upper Setekwa River, taken with a typical ?. The 

 examples of the aberration are all slightly smaller than those of the tyjje form in 

 both sexes. 



14. Ophiusa dentilinea Beth.- Baker 

 ab. albifusa ab. nov. and ab. rectilimes ab. nov. 



The ab. albifusa differs from typical dentilinea in having the oblique ante- 

 median space between inner and median lines filled up witli white in place of 

 brown, its inner half dusted with brown ; the inner line is more strongly marked, 

 and the whole basal area within it filled up with dark fuscous ; the black markings 

 which go to form the prae-snbmarginal shade are all larger and more decided, and 

 the space between them and the outer line is brown. In the ab. rectilimes the 

 oblique median line, which in the type form and in albifusa is bisinnate, is fine and 

 straight, and the whole wing is tinged with reddish brown, the ground colour 

 appearing darker throughout. 



The type of the ab. albifusa is a ? from the Oetakwa River, Snow Mts., 

 Dutch New Guinea, taken from October to December 1910, by A. S. Meek ; that 

 of rectilimes, which may probably prove a sejiarate species, also a ?, is from Welsch 

 River, British New Guinea (Weiske). 



15. Ophiusa conspicua spec. nov. 



Forewing : bright whitish grey tinged with lilac and dusted with blackish 

 atoms ; subbasal and inner lines brown edged with pale, the former straight, 

 reaching median vein, the latter oblique, slightly concave outwards and parallel to 

 the median line ; the basal area is filled up with grey-brown, and the inner half 

 of the antemedian belt is dusted with blackish ; outer line obliquely concave out- 

 wards to vein 6, there angled, then straight and oblique to inner margin, before 

 which it is shortly curved outwards, meeting median line at a point ; space included 

 very broad, deep chocolate brown ; the outer line is edged by a bright white line, 

 followed above angle by a space of pale gronnd colour, and below it by a narrow 

 brown shade, limited by the dentate-lunnlate sabterminal line, and widened to 

 tornus ; a deep black-brown narrow apical blotch, inwardly edged by a short 

 white line ; outwardly indented, its lower end inbent to touch the angle of outer 

 line; terminal area and fringe of the pale ground colour, with a row ot dark 

 terminal dots. 



Hindwing : blackish, the basal area paler before a slight pale oblique median
