[In an example from Rossel Island, on both surfaces of 

 the posterior wings, between the 2nd and 3rd median'ner- 

 vules is a discal suboval black spot. In another example, 

 the submedian area is silky yellow, with two black spots at 

 its lower end ; and the light rays of the anterior wings on 

 the undersurface are considerably broader than in the 

 examples quoted above.] 



Head and thorax velvety black ; antennas black ; pro- 

 notal collar coral red. Underside black, with the usual 

 pectoral red patches ; legs black ; eyes nitid brown. 

 Abdomen above, rufous grey, and black towards the anal 

 end, the articulations lemon yellow ; on the underside 

 yellow, with the usual lateral black dots ; anal valves dark 

 creamy-white. 



Length of costa of anterior wing 68 mms. ; of outer 

 margin, 50 mms. ; of inner margin, 33 mms. The pos- 

 terior wing rounded, with the costa much curved — the 

 abdominal margin nearly straight, and 31 mms. in length. 

 Greatest width of wings 28 mms., greatest length 39 mms. 



Length of abdomen or antennas 26, and of thorax with 

 head, 20 mms.

2 . Anterior wings rufous black ; the adnervular rays 

 grey white, with a creamy tint, all delicately scaled. 

 The grey white streaks of the discoidal cell extend from 

 the distal end half way towards the base of the wing, 

 thereby framing in one half of the black cell area ; in this 

 light grey frame the pseudoneura are quite seen ; in some 

 examples the black area is divided half-way towards the 

 base by the grey into two beautfully shaped pyriform marks, 

 their widest ends being at the distal part of the cell, and 

 the second or central pseudoneurus passes midway through 

 the grey like a true vein ; the other pseudoneurae are 

 well shown in the grey framing, until they are lost in 

 the black towards the cell base ; but between these two 

 varieties of cell pattern there are many gradations, till in 

 some examples the grey almost entirely occupies the cell 

 nearly to the base, leaving the black pyriform marks very 

 small and shorter in length. 



The undersurface of the wing as above, only that the 

 light marks are a little lighter, and not scaled, except in 

 the cell, and the black becomes more of a greyish brown. 



Posterior wings, outwardly lunate, yellow ; the outer 

 margin consists of a band of seven cone-like black 

 lunations, extending into the disc about 10 mms. each, 

 or 13 mms. each from the base of each section 

 of the outer margin ; a transverse discal band of seven 

 pyriform black marks, varying in length, of which the two 

 nearest the abdominal margin are the longest, and the 

 mark midway of the disc is the smallest ; the base of the 

 discoidal cell to i-3rd is black, and also the base of the 

 submedian area— the latter being creamy-whitish entirely 

 to the inner margin, and slightly scaled ; one half of the 

 lower part of the wing, nearest to the abdomen, is dark 

 scaled ; the veins are very stoutly black, especially the 

 the subanal ones, the latter separated from each other by 

 yellow, and from the black of the marginal lunations ; and 

 the scaling of the corresponding portion of the wing on the 

 upper side is absent from the undersurface. 



_ Head, antennas, and thorax black, eyes castaneous 

 nitid brown, pronotal collar crimson, underside of 

 thorax and legs black, with the usual lateral or pectoral 

 crimson patches. Abdomen above dark silky brown : 

 beneath yellow, with two rows of lateral black dots, [the 

 males have only one], anal tuft deep fleshy red. 



Length of costa 86 mms. ; of outer margin 64 mms. ; 

 of interior margin 40 mms. ; greatest width of wing 45 

 mms. Greatest length of the posterior wing 52 mms. ; 

 greatest width 38 mms.

Habitat. Assam. In the Author's Museum. 



An example of the ? of this species in my collection, 

 from Omei Shan is bluish-grey on the anterior wing rays ; 

 the cell has two short narrow pyriform black marks only, 

 and is densely scaled on a grey ground nearly to the base ; 

 and the discal and submarginal black marks of the 

 posterior wing on the under surface are rather smaller, 

 the submarginal more oblong, more separate from the 

 black frings lunules, and the discal marks are quite conical. 

 Length of anterior wing costa 82 mms. The underside 

 of the abdomen with the second row of lateral black dots 

 so large as to occupy nearly all that part of the body. 



In a second example from the same locality, all the 

 marks of the posterior wing are broader and longer, so as 

 almost to touch each other, and to greatly restrict the 

 yellow area of the disc on the upper surface. 



[Note. — The scaling of the lower half of the posterior 

 wings on the upper surface is a constant character in the 

 2 of this species, and serves to readily distinguish it from 

 the S 2 of Minos or Cerberus. ]

A specimen of the <? from Oby or Obim Island in the 

 Author's Museum, only differs from the typical examples 

 from other localities in having on both surfaces of the 

 posterior wings, just above the submarginal cone, and 

 between the 2nd and 3rd median branches a suboval black 

 spot, and an increased density of the delicate black hairs 

 which flow longitudinally over the yellow area within the 

 2nd and 3rd median branches, and the submedian yellow 

 from the base. 



The Island of Oby, or Obim as it is spelled in my map 

 in vol. I., and also in the old maps of this region, is a 

 small mass of land situated south, with a slight inclination 

 east of Batjan, in longitude i2j°2o' to i28°io', and S. 

 latitude i°i5' to i°4o'.
