6* . Anterior wings silky black, shot with a greenish- 

 blue sheen ; adnervular rays ochraceous white, but much 

 less bright than in the type form, being subdued and 

 shaded into the black by dark atoms and reflections till 

 their outline is nearly lost in the general black towards the 

 outer margin. Under surface of primaries black, but 

 rather less silky ; the adnervular rays are very prominent, 

 and form a group from the inner margin to the 4th 

 submedian nervule, being more bluish black at the low- 

 est and the highest situated of the series ; within the cell 

 are three ad-pseudonervular short white rays of atoms, 

 and part of the median nervure is also margined with 

 white. 



Posterior wings : the cell and disc silky grey black, 

 shot with opalescent tints, in green, blue and red, with a 

 submarginal band of seven golden yellow spots, which, as 

 in the type form, diminish in size towards the abdominal 

 or anal angle, having on each side a black border, sinuous 

 in outline, extending from the anal angle to the base of 

 the costa ; the abdominal fold concealing the androconia, 

 very gracefully formed and prominent, also silky black, 

 shot with opalescent tints. Under surface : The cell and 

 disc pearly white, more tinged with yellow towards the 

 base ; the yellow submarginal band is really continuous — 

 the inner border of black consists of three large spots 

 from the 3rd median branch to the discocellular vein, 

 after which the black is continuous to the base ; the outer 

 marginal black is continuous throughout the whole out- 

 line ; the veins very black — the psuedoneura black, united 

 by black atoms at their base ; the abdominal margin 

 black, irrorated by white atoms, with a dark, long fringe. 



Head, antenna? and thorax velvety black, breast with 

 no red spots ; abdomen golden yellow above, more lemon- 

 tinted beneath, with black spots on each segment more or 

 less large — the basal and 5th segments entirely covered 

 above with black. 



Length of costa of primaries, 83 mms. ; of outer mar- 

 gin, 62 mms. ; of inner margin, 45 mms. ; width of wing 

 at base 9 mms. ; width of wing of secondaries 38 mms. ; 

 greatest length 51 mms.

Dis- 



The differences between this variety and the type forms 

 are so considerable that when compared side by side, 

 they appear abundantly distinct, though not sufficiently 

 to justify us in regarding them as more than a sub-species. 

 The whole insect is altogether darker than the type on 

 both surfaces, and is really a bolder, richer and more 

 beautiful insect. 



2 . Anterior wings black ; the adnervular rays extend 

 from the submedian vein to the 3rd subcostal branch, 

 and are broader in form and size than in the type form 

 on pi. 29 of this work ; the upper ones are tinted with 

 yellow ; the white rays bordering the pseudonera in the 

 cell are also larger and broader than in the type form. 

 Under surface as above, the white marks being increased 

 in size and intensity. 



Posterior wings : Cell brownish black, with delicate 

 hairs proceeding from the base — the same black is con- 

 tinued between the median and submedian veins, and to 

 the abdominal margin ; the yellow discal band of spots 

 or marks commences at the costa, and is continued to the 

 ist median nervule — the first three of them being bordered 

 with black on both sides, the 4th only on the outer 

 margin, and containing black spots— the 1st very small ; 

 the 5th division of the disc has a hastate yellow spot 

 bordered by white at its apex, followed below by an ovoid 

 black spot immersed in an area of grey, with a yellow 

 sinuous spot below it, followed by the black outer margin ; 

 the next division is similarly arranged, only that the black 

 spot is larger and narrower, and the yellow less ; the sub- 

 marginal black border runs in a sinuous course to the 

 anal angle, the area between the 3rd submedian branch 

 and the submedian veins, when not black is white 

 clouded with black spots and atoms and a little yellow — 

 the white in a thin line continued along the submedian 

 fold to the base. All the discal areas are more or less 

 subdued by dark scaling. Under surface, similar to above, 

 except that a little less than i-3rd of the cell at the distal 

 end is grey white, subdued by black atoms ; the yellow 

 is purer and more diffused over the lower area of the disc 

 between the 1st and 3rd median branches ; more dis- 

 tinctly white without from the 3rd median branch to the 

 submedian fold, with black subovoid spots in each space 

 —the 2nd yellow space from the costa with the spot very- 

 small, and more ovoid than above ; the first yellow 

 division, as above, contains no black spot : the outer 

 marginal black border at from the ist to 3rd median 

 branches is interrupted by the white fringe lunules, with 

 only a couple of black spots above — that in the first space 

 being narrower than the second ; cloudings of black atoms 

 also border the 3rd median branches ; a =» shaped atomic 

 white mark at the apical angle, and a short line of white
