 (liinlitless tlie ? of jx'rrerx'i ; it is very faded, Init, sliows the black sliailowy jiost- 

 discal liaiid on the hindwiiig which is present in the S, and the lobe ]{■' of the 

 forewing projects as strongly as in the S . Abdomen with black stigma-dots. 



t?. Tenth tergite (PI. XXIV. f. Is) broad, constricted at base and in middle, 

 above longitudinally impressed mesially, sides convex, a])e,x divided into two short 

 pointed lobes : sternite (PI. XXIV. f. 19) small, obtusely triangular, sides obli(|nely 

 and shallowly sinuate. Clasper (PI. XXXIII. f. 5) apically sinuate, the ventral 

 lobe produced into a long, pointed, strongly chitinised process which curves upwards; 

 ventral margin of clasper inerassate, basally armed with two sharji, long teeth, 

 beneath which there is another small tooth ; the postmedian part of inner sheath 

 of clas])er convex, raised into a broad fold ventrally, which ends in a boot-shaped 

 ol)tuse jirocess {pr). Penis-sheath without armature. 



?. Vaginal plate (PI. XVII. f. 8) large, distal margin sinuate, with the 

 angles rounded ; orifice proximal, a low ridge in front of it. Eighth tergite 

 halfmoon-shaped, the apical margin being strongly rounded. 



Early stages not known.

S ? . Butler's figure of the ? is very bad ; it does not at all agree with the 

 description. The type seems to be lost, or may be contained in some obscure 

 collection which we have not seen. A c? in the Tring Museum is doubtless this 

 species ; it agrees in the shape of the forewing nearly with q>«tdr>pniirtatu,<^, but 

 the outer margin is less sinuate between S0° and R^ ; upperside of hindwing, 

 middle of basal two-thirds of underside of forewing, and a streak along abdominal 

 fold of underside of hindwing, ferruginous. Anterior tarsns blackish. Oar Borneo 

 ? has (like the Penang S) the forewing straight from 8C" to angle, there being 

 very small teeth at K' and M'. The hindwing is mucli more brownisli than in the 

 cJ, the forewing below is only feelily shaded with ferruginous, and there is no 

 ferruginous streak before the abdominal margin of the hindwing. The black 

 stigmata are distinct. The outer discal line of the forewing above is also distinct, 

 convex beyond R', snbmarginal area with a series of paler patches. Outer discal 

 line of underside very prominent, straight, the wing pale proximally of the line. 



S. Tenth abdominal tergite very remarkable (PI. XXIV. f. 15), mesially 

 membranaceous and clothed with dispersed bristles, sides produced into a long, 

 curved and pointed process ; sternite (PI. XXIV. f. 14) short, apical margin evenly 

 concave, the sides slightly projecting, ('lasj)er (PI. XXXIII. f (i) triangular, apex
