S . Anterior wings velvety-black ; the adnervular rays 

 golden-yellow, but only very slightly shewn, being little 

 more than a few short streaks of yellow scales, and these 

 very faintly indicated on the lower part of the disc ; a 

 very contracted yellow group of scales in the cell, on the 

 upper half of the discal end ; also slight streaks of yellow 

 scales along part of the costal and subcostal nervures ; 

 the veins slightly rufous brown. Undersurface almost 

 entirely as above ; the fringe lunations of the outer 

 margin white. 



Posterior wings a rich golden yellow, with dull green 

 reflections, or opalescence ; the scalloped or dentated, 

 margin is, like that of the type form, narrowly black and 

 graceful, extending as a long black mark half-way up by 

 the 3rd median nervure ; the costal margin, a small basal 

 portion within the cell, the submedian area and the 

 abdominal fold concealing the androconia are deep velvety- 

 black ; a few long black hairs flow down from the median 

 vein over the yellow ; and a few minute black atoms are 

 grouped on the yellow disc between the ist and 2nd 

 discoidal nervule. The character and colour (nearly a 

 flesh tint) of the androconia (as shewn in my plate fig. I.), 

 is similar to the prevailing tint of the abdomen. 



Undersurface as above, with a thin line of dark atoms 

 parallel to the black from the apical angle ; from the sub- 

 median nervure a line of rufous fringe-hairs proceed, and 

 partly covers the sides of the abdomen when the insect is 

 at rest. 



Thorax, head and antenna? velvety-black ; eyes dark 

 rufous brown ; beneath, black, with red pectoral patches 

 and red pronotum. 



Abdomen fleshy red-brown, with a rather darker dorsal 

 longitudinal stripe ; each side of the lighter part of the 

 abdomen is margined by black, with yellow outline ; the 

 upper part of the anal valves black ; the sides and sub- 

 dorsum yellow and yellow-green, with the usual lateral 

 rows of black dots ; anal valves flesh-coloured. 



Length of costa 74, outer margin 54, and inner margin 

 41 mms. Greatest length of posterior wing 45, and width 

 33 mms. 



Length of abdomen or antennae 29, and of head and 

 thorax 23 mms.

Hab. Karo, Sumatra. 



? . Anterior wings dark rufous brown ; the adnervular 

 rays from the 2nd subcostal nervule to the ist median 

 nervule sordid yellow-white and long ; all below of the 

 same colour, short, variable in length and shape, begin- 

 ning at more than half way from the median vein, or 



nearest to the outer margin, and subcuneiform ; the mark 

 within the cell irregular in shape at the distal 5th of the 

 cell, and sordid whitish-yellow. 



Undersurface as above, but the light marks are a purer 

 and brighter whitish-yellow, and nearly all are margined 

 with light yellow atoms. The fringe lunules white. 



Posterior wing with yellow disc, and the distal half of 

 cell yellow ; a band of 6 large suborbicular black discal 

 spots, followed by a scalloped submarginal band of 

 yellow ; the broad outer-marginal band is densely black 

 and lunated ; fringe lunules whiter ; the base, costa, basal 

 half of the cell and abdominal margin black, but the 

 submedian area is deeply rufous with a line of light 

 yellow atoms ; the black edge of the submedian sinus is 

 powdered with greenish and black atoms on the yellow ; 

 the submarginal yellow band is also subdued by black 

 atoms ; the abdominal margin is irrorated by yellow 

 scales ; abdominal fringe black, a mass of delicate dark 

 hairs proceeds from the base into the yellow of the cell, 

 and lower part of the yellow disc. 



Undersurface as above, except that the yellow areas 

 are not subdued by black atoms, only one narrow streak 

 of yellow atoms is on the abdominal margin, there are no 

 dark hairs proceeding from the base into the yellow, one 

 rather small black ovoid spot follows the band of 6 large 

 black macula? below the 3rd median nervule, and all the 

 macula? and the inner lunate edges of the outer-marginal 

 black band are slightly powdered with grey atoms. 



Head, antenna?, eyes, and thorax black ; abdomen very 

 dark brown ; underside of thorax black-brown ; legs 

 blacker ; no red pronotum or pectoral red marks. Abdo- 

 men beneath yellow, with the usual row of lateral black 

 dots ; the segmental incisures well defined. 



Length of costa 76, of outer margin 60, and inner 

 margin 55 mms. ; length of posterior wing 55, and width 

 40 mms. 



Length of abdomen 30, of antenna? 26, and of thorax 

 with the head 23mms. 



Length of 



ist pair : femur, 11 ; tibia, 8 ; tarsi, 12 mms.

The $ of this form in its general colouration and ap- 

 pearance wonderfully resembles the $ of P. cuneatus of 

 Oberthiir from W. Java, except in the omission of the 

 beautiful discal row of cuneiform black marks on the 

 posterior wings of that species.
