giving it a very unusual appearance. The hind margin 

 extends down nearly in a straight line till it reaches the 

 tails which curve outwardly, are very narrow till they 

 reach a fine point, and nearly as long as the rest of the 

 outer margin ; the abdominal margin is very beautifully 

 formed, sharply divided by a median fold and at its 

 junction with the tail by a sharp dentation, as if a small 

 triangular piece had been excised to more conveniently 

 allow the marginal section to lie over on to the rest of the 

 wing if needful, as it probably does sometimes ; the 

 abdominal margin is not furnished with a pouch or recep- 

 tacle for androconia like the $ members of the Pompeoptera 

 as might have been anticipated, but it possesses a most 

 remarkably broad and elegant creamy -white fringe attached 

 to the median fold on the under surface ; the whole of 

 the wing, which includes the greater part of the discoidal 

 cell is a rich silky golden, semi-diaphanous, texture divided 

 by the subcostal nervure and its ist branch and the 2nd 

 discocellular nervule— the gold extending longitudinally 

 towards the base of the caudal prolongations or tails where 

 it tapers off to a point ; a submarginal band of golden 

 green extends down the entire wing, and i-3rd within 

 the narrow tail, where it unites with a second narrow 

 green band which extends to the base, occupying that 

 part of the cell not filled by the silky gold, and also a 

 small scalene-triangular discal spot on the black outside 

 the 2nd discocellular nervule ; a small golden spot in the 

 green outside the 2nd subcostal branch ; the inner mar- 

 ginal portion of the wing and abdominal fold are a deep 

 velvety-black. The posterior margin is narrowly black 

 from the costa and both sides of the tail ; at the inner 

 margin of the tail are a few golden green atoms ; a faint 

 line of grey atoms between the 2nd and 3rd subcostal 

 nervules. 



Undersides of anterior wings with the discoidal cell 

 and nearly all the discal area golden green or golden 

 yellow, a lighter green at the base of the cell, darker at 

 the farthest from the base, extending more or less out- 

 side the cell till it becomes entirely golden yellow ; costa 

 brownish black ; outer margin brown black — narrowly to 

 the 3rd discoidal nervule, when it broadens irregularly 

 till the black extends, and indents into the spaces 

 bounded by the ist discoidal and 4th and 5th sub- 

 costal nervules encroaching in two places con- 

 siderably into the disc ; the veins are all strongly 

 black, delicate in structure, and broadly margined with 

 velvety black ; the golden green nearest the apex is dusted 

 with black atoms, and the black next below by golden 

 green atoms ; the inner margin is narrowly black half-way, 

 then broadly black on the area containing the interno- 

 median vein to the base. 



Underside of the secondary wings with a similar por- 

 tion corresponding to that on the upperside golden silky, 

 with also a small spot of the same colour corresponding 

 to that above — the veins being a darker yellow and well 

 expressed. The remainder of the wing is golden green 

 down to 2-3rds of the tail, with veins of the same colour ; 

 no black in the costa, and only a narrow black outer and 

 inner marginal line, broadest at the inner side of the tail 

 with i-3rd of the tail entirely black ; abdominal margin 

 or fold, through which the submedian veins runs, and to 

 the median line of which the fringe is attached, a delicate 

 pearly silver grey ; the bifid precostal nervure is black 

 with a faint outward curved line of dark atoms above it. 



2 . Anterior wings, upper surface, smoky brownish 

 black, with a slightly opalescent greyish sheen ; very 



opalescent along the inner margin and towards the hind 

 margin when viewed obliquely opposite the lights an 

 irregular large bidentate tetrahedronal patch of while 

 within the discoidal cell, occupying a position not quite 

 midway of the entire wing length, being situated nearer 

 to the base than to the apex; there are 8 submarginal 

 white spots, and 2 discal ; the ist (within the 3rd and 

 4th subcostal branches) oblong : the 2nd (within the 4th 

 and 5th subcostal branches) accuminate : the 3rd (within 

 the 5th subcostal and ist discocellular) oblong, sinuate 

 within and dentate without : the 4th (within the ist and 

 2nd discocellular branches) accuminate and shorter : the 

 5th (within the 2nd discoidal and ist median branches) 

 obtuse cuneiform : the 6th (between the ist and 2nd 

 median) small, suborbicular : the 7th (between the 2nd 

 and 3rd median) rather larger, pointed towards the hind 

 margin : the 8th (below the 3rd median) is suboval and 

 small ; a short discal oblong grey white mark within the 

 7th submarginal spot, and a spot of grey-white atoms 

 nearly close to the median vein, between the ist and 2nd 

 branches ; all the white marks are modified into grey 

 white more or less by grey atoms or scales. 



Posterior wings above, smoky brownish-black, with a 

 slightly greyish sheen ; a discal band of ochreous greyish 

 white, very narrow at the costa — and so broad towards the 

 inner margin as almost to fill up the entire space between 

 four of the nervules — extends from the anterior to 

 the anal angle, and contains suborbicular black spots, the 

 ist and 4th being the largest, and the 2nd, 3rd, and 5th 

 the smallest ; below, these, as well as in the two divisions 

 of the white band above the spaces, are olive yellow-brown 

 —the greyish part of the white, and the olive tone of the 

 yellow brown being caused by the beautiful graduation of 

 the grey and darker scales with which the band is more 

 or less dusted ; this band is strongly lunulate without, 

 and irregularly sinuate nearest the cell ; the submarginal 

 portion of the wing broadly brown black, with white 

 fringe lunules ; the precostal nervure prominent on a 

 slightly shining surface. 



Posterior wings, under surface, a rich warm dark brown 

 or black, the veins all standing Avell in relief ; the white 

 markings similar in number, position, and shape as above, 

 except that the two discal nearest the cell are larger, and 

 the 8th is longer and less ovoid, and a small or 9th white 

 submarginal spot is found below the submedian pseudo- 

 neurus or fold ; none of the light markings are modified 

 by dark atoms ; the outer -margin with white fringe lunules. 



Posterior wings, under surface, more intensely dark- 

 brownish black ; all the veins (which are not robust) stand- 

 ing in prominent relief ; the discal band occupies exactly 

 the same area as above, the 5 black spots being also of 

 the same size ; the space above the latter a delicate 

 creamy-white, below a pure pale lemon yellow — the two 

 divisions above the spots of the same yellow ; the lunula- 

 tions towards the posterior margin rather more sinuate 

 than above, and softened into the black by black atoms ; 

 the outer margin broad black as above, with creamy 

 white fringe lunules ; the space within the precostal cell 

 is white. 



Head : Eyes very dark brown and prominent, with light 

 red margin. Thorax velvety black, without a green longitu- 

 dinal striga ; sternum : prothorax black, meso- and 

 metathorax crimson ; legs black, except the femora, which 

 are pale yellow and black. Abdomen, ist segment dark 

 brown, with crimson scarlet hairs on either side ; 2nd 

 segment greenish grey with black scales and a central
