? . Anterior wings velvety black, with the adnervular 

 light rays very distinct ; within the cell at or near the 

 distal end only faint white lines, which also slightly 

 emphasize the pseudoneura ; fringe lunules white, and 

 only delicately indicated. Undersurface as above except 

 that the light rays are more prominent, and in 2-3rds of 

 the cell they very prominently emphasize the pseudo- 

 neura. Posterior wings : the yellow area within the' cell 

 (one-half its extent) and without on the disc is, similar in 

 shape and extent to that of Criton and Plato ; the rest 

 of the wing is velvety black. Undersurface as above. 

 The abdominal marginal fringe-hairs rather long. 



Thorax, head and antennas black ; pronotal collar red ; 

 abdomen very dark brown, with yellow green margins, 

 underside of thorax with the pectoral red mark, of 

 abdomen partly black, and partly greenish yellow ; anal 

 valves black. 



Length of costa 67, of outer margin 50, and inner 

 margin 31 mms. ; width of posterior wing 25 mms. ; 

 greatest lengh 37 mms. 



Length of abdomen or antennas 24 mms. ; of thorax 

 with head 24 mms.

2 . Anterior wing very dark brown ; the adnervular 



rays well represented, subdued by brown atoms ; 2-3rds of 

 the cell also with 3 long patches of scaly-white, through 

 which the pseudoneura pass ; an adnervular white streak 

 attached to the submedian vein ; undersurface as above, 

 except that all the light rays are whiter and more promi- 

 nent, and they nearly fill the cell. 



Posterior wings : 2-3rds of the cell yellow ; also about 

 2-3rds of the disc yellow, near the submedian vein 

 suffused with white ; within the discal yellow area are 4 

 subconical black spots united at their base with the sub- 

 marginal black ; at the upper part of the wing the black 

 of the disc occupies the 2 spaces where theoretically 2 

 more subconical marks should be ; 2 or 3 small white 

 streaks at and near the anal angle. Undersurface nearly 

 as above ; all the rest of the wing on both surfaces velvety- 

 black. Head, antennas and thorax black ; eyes brown ; 

 abdomen dark brown, with the last 3 segments margined 

 yellow. Underside of thorax with the pectoral red patch ; 

 legs black ; abdomen yellow, tne annulations or segments 

 well expressed with black.

Hab. Sumba, where it is common. The var. sumba- 

 wana is taken in Sumbawa, the form called by Staudinger 

 Socrates is found in Wetter, Sumbawa, Alor, and Adonara.
