Family Apa'I'uridjs. 

 PoTAMis (or Apatuea) tJLupi, n. sp. PI. X, Fig. 2, d' . 

 Male, above, foreioing, black, quite unglossed, markings light och- 

 reous-fulvous, the base, costa, hind-margin, and a few submarginal 

 touches diffused rufous- bro wn ; two small light ochreous spots above 

 the radials, the upper largest ; an obliquely transverse fulvous macular 

 band from the subcostal vein to the lower angle, the first three spots 

 being elongate-quadrate, separated only by veins, the last with a pale 

 space beyond it, the fourth well separated from the first three, outwardly 

 incised, the fifth subquadrate, diffused, close to the outer margin, 

 with a large black spot partly enclosed by its inner border, the sixth 

 slender, lying along the margin of the interno-median space ; another 

 transverse band from the upper edge of the cell to the submedian vein 

 sloping obliquely outwards, and divided into three parts by the median 

 vein and its lower branch, occupying the middle half of the cell (with 

 a diffused streak at the lower angle, almost separated from it by an 

 oblique black crescent), the basal half of the lower median and half of 

 the interno-median space. Hindiving ochreous-fulvous, the abdominal 

 margin as far as the lower, and in the middle of the disc the 

 upper median branch, covered with diffused black scales, the apical part 

 also sordid, the veins dark, the marginal line and a broader submarginal 

 line thickened at the crossing of the veins, black, within which is a lino 

 of five partly united dark spots diminishing anally to mere streaks. A 

 large and distinct black spot discally in the lower median space. 



Below, foreiving, paler tawny, the black spaces above replaced by 

 dusky fulvous ones, except a large black spot in the lower median space, 

 and a diffused blackish one below it, near the lower angle of the wing. 

 The two subapical spots, and a touch on the costa beyond the cell, lilac- 

 white. Hindwituj light fulvous, the base slightly glossed, pale ; a large 

 ocellus pupilled with purple in the lower median space; a lustrous lilac- 

 white band across the wing discally, bordered inwardly by a darker 

 ferruginous band broadest near the costa ; a submarginal ferruginous 

 line, within which are a few obscure lilac-white touches, between which 

 and the lilac band lie four good-sized lilac-white spots and some ferru- 

 ginous touches. 



One male taken by Lieut. Hartert on the Dikrang near Sadiya, an- 

 other by me at Kobong between Sadiya and Margherita. One or two 

 others were seen. 



This butterfly has no near allies. In general appearance it is 

 something like Dilipa morgiana or Sephisa diehroa. In its small body 

 and rather weak flight it resembles Apatura {Eulaceara) ostcria, and if
