c? ? . The Sikhim specimen, which was described as the ? of oliracea, ia 

 doubtless the ? of peners'i ; it is very faded, bnt shows the black shadowy post- 

 discal band on the hindwing which is jjresent in the S, and tlie lobe 1{^ of tlie 

 forowins,^ projects as strongly as in the S. Abdomen with Ijlack stigma-dots. 



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

 above longitndinally impressed mesially, sides convex, apex divided into two short 

 l)ointed lobes ; sternite (PI. XXIV. f. 19) small, obtusely triangnlar, sides oblic|nely 

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

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

 ventral margin of clasper incrassate, basally armed with two sharp, long teeth, 

 bcneatli which tliere is another small tootli ; the postmedian part of inner sheath 

 of clasper convex, raised into a broad fold ventrally, which ends in a boot-shaped 

 obtuse process {pr). Penis-sheath without armature. 



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

 angles rounded ; orifice ])roxiinal, a low ridge in front of it. Eighth tergite 

 halfmoou-shaped, the apical margin lieing strongly rounded. 



Early stages not known.

c? ? . 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 S in the Tring Museum is doubtless this 

 species ; it agrees in the shape of the forewing nearly with (jnadripnnrfatas, but 

 the outer margin is less sinuate between 8C° and R^ ; upperside of hindwing, 

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

 fold of underside of hiudwing, ferruginous. Anterior tarsns blackish. Our Borneo 

 ? has (like the Penang S) the forewing straight from SO'' to angle, there being 

 viM-y small teeth at R^ and M^ The hindwing is much more brownish than in the 

 S, the forewing below is only feebly 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', submarginal area with a series of paler patches. Outer discal 

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



3. 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. Clasper (PI. XXXIII. f. 6) triangular, apex 

 slightly curved ventrad, apical edge armed with small sharp teeth : a small
