6* . Anterior wings intensely velvety black, shot with 

 grey reflections ; adnervular rays only just visible, or 

 almost shaded into the black of the wing. Undersurface 

 as above, except that the adnervular rays, and a slight indi- 

 cation of white at the distal end of the cell are rather 

 lighter ; fringe lunules dull white, and very delicate. 



Posterior wings velvety black, shot with grey reflec- 

 tions ; a narrow discal band of yellow extending from the 

 subcostal nervure to a speck of yellow outside the 3rd 

 median nervure ; a small speck of yellow also at the distal 

 end of the cell. Underside as above, except below the 

 median vein and over the submedian area, which is rather 

 lighter black. 



Head, antennae, thorax, and abdomen densely black, 

 anal valves reddish black ; pronotal collar red ; underside 

 of thorax black and red, abdomen black, legs robust and 

 black. 



Length of costa of anterior wing 61, of outer margin 

 58, and inner margin 30 mms. Width of posterior wing 



25, and length 39 mms. Length of abdomen or antennae 



26, and of head and thorax 20 mms.

? . Anterior wings light brown ; adnervular light rays 

 sordid creamy-white, extending from the cell almost to 

 the hind or outer margin, and from the costal nervure to 

 the 3rd median nervule, again partly along the submedian 

 fold, with a large leaf-like mark at or near the anal 

 angle, through which the distal portion of the submedian 

 vein passes. The sordid whitish mark also occupies 

 rather more than i-3rd of the distal portion of the cell. 

 Undersurface as above, except that the light marks are 

 less sordid ; fringe rays creamy white and delicate. 



Posterior wings deep black, with olive grey reflections ; 

 the central yellow patch of ruddy yellow is small, only 

 extending on the disc from the ist discoidal nervure to 

 the submedian fold, and i-4th of the cell at its distal end, 



or less than i-4th of the whole wing; fringe lunules 

 creamy white ; undersurface as above, the yellow area 

 whiter in tint. 



Head, antennae, eyes, thorax and abdomen above and 

 below varying degrees of rather dark brown ; pronotal 

 collar red ; pectoral patch also red. 



Length of costa of anterior wing 75, of outer margin 56, 

 of inner margin 46 mms. Length of posterior wing 50, 

 and width 33 mms. Length of abdomen or antennae 26 

 mms. ; of thorax with the head 21 mms.

 of these descriptions are in the Tring Museum of the Hon. 

 Walter Rothschild. 



The pseudoneura in the cell of the anterior wing are 

 in two groups, in both sexes. In the $ the ist or upper 

 pseudoneurus originates at a short distance from the base 

 of the subcostal vein, and terminates just beyond the 

 base of its 3rd branch ; the 3 other pseudoneura com- 

 mence at the base of the wing, spreading out fan-like to 

 the distal end, or 2-3rds of the extent of the cell. In the 

 ? the arrangement is very nearly the same, but the ist 

 and 4th commence at the base, while the 2nd and 3rd 

 branch off a little above the base of the 4th. 



[The ? of this species closely resembles the var. of 

 Dohertyi ? figured on Plate 64, figs. 7 and 9, but the 

 posterior wings are more dentate in Dohertyi 2 , and the 

 $ of Ins is smaller and different in outline from the same 

 sex of Dohertyi. The pseudoneura of Dohertyi in both 

 sexes are arranged in 2 groups of 2 each, the 2nd branch- 

 ing from the ist at i-3rd of its length, and the 4th 

 branching from the 3rd at half its length, — thereby show- 

 ing that the two forms are only distantly related.]
