6*. Upper wings arched and somewhat acute at the 

 angle. Lower wings somewhat abbreviated, the apical 

 angle slightly projecting. Upper wings with only the 

 slightest indication of white lunules * ; velvety black, 

 diluted with fuscus, more especially toAvards the margin, 

 where it graduates into a very perceptible red-brown ; the 

 subcostal longitudinal band fiery red (deep glowing 

 orange) shot with golden green, when seen obliquely against 

 the light. Opposite the light the scarlet orange is 

 intensely brilliant. This band is unusually broad, as in 

 Crcesus, commences within the discoidal cell at a short 

 distance from the base, where it is at its narrowest, then 

 broadening till it is more than 2-3rds the width of the cell ; 

 from thence it extends outside the cell nearly to the apex 

 of the wing. Within this area are included a part of the 

 1st and 2nd subcostal branches, as a thin line of colour, 

 between the 2nd and 3rd the colour extends 16 mm. 

 towards the apex, between the 3rd and 4th to within 

 4 mm. of the apex, between the 4th and 5th, decreasing in 

 length posteriorly, and between the 5th and 1st discoidal 

 nervule a still shorter, irregular tetragon, the lower edges 

 of the divisions terminating with fiery atoms, forming 

 within the 1st and 2nd discoidal nervules a small spot of 

 atoms ; as the black runs in prominently at the first 

 discocellular nervule wedge-shaped, and is generally 

 irregular in its impingement on the red band along its 

 whole outer length, it gives the edge of the band an 

 irregularly ragged appearance, though above it follows 

 the curve of the costa accurately. The sexual sericeous 

 patch or brand is pupseform, and light fuscus — the head 

 towards the base, and the tail curved up in the direction 

 of the apex of the wing and extends from the submedian 

 nervure to nearly the 1st median branch, running 

 counterminous with the median nervure at nearly midway 

 between it and the outer and interior margins ; a small 

 patch of fiery orange and lemon at the base on the 

 interior margin is partly divided by the branch of the 

 submedian nervure, and is longer, formed by atoms of 

 colour. 



Posterior wing fiery orange, subdued by scattered 

 black atoms ; within the discoidal cell a subtriangulate 

 patch of golden yellow, immaculate, occupying 3-5ths 

 of the cell, and not quite close to the nervures ; a 

 smaller patch between the costal and subcostal nervures ; 

 a hastate patch between the 1st and 2nd subcostal 

 branches, the 3 forming a large almost homogeneous patch, 

 divided by the subcostal vein and its branches — the veins 

 being black edged with the fiery orange ; between the 

 costal nervure and its top branch following the golden 

 patch is a cuneiform black spot pointing outwards, 

 followed by a golden yellow sublunate spot ; between the 

 1st and 2nd subcostal branches is an orbicular black spot 

 just below the hastate golden patch, followed by a sub- 

 lunate gold spot ; also a suborbicular or ovate black spot 

 between the 2nd subcostal branch and the discoidal 

 nervure ; and a faint atomic spot between that and the 

 1st median branch ; exterior marginal border black, 

 irregularly curved with golden atoms at their inner edge ; 

 interior margin and anal angle black ; abdominal fold 

 brown black, its underside a light lucent brown, fringed 

 with very long brownish ochreous hairs ; the median 



• In closely examining the fringe of the wings with a lens, I find that the 

 under sides of the type have been cleverly patched (the specimen, when captured, 

 was evidently not in its pristine perfection) and the edges of the wings have apparently 

 been slightly trimmed with a scissors, thereby destroying the slight Simulations, and 

 making the margin quite straight But there is a faint indication of white in those 

 places where the lunules would be ; and, as a matter of fact, they are to be found 

 slightly represented in the margin of every perfect specimen of any species of Orni- 

 thoptera, as far as I have been able to judge. 



nervure well expressed in black with golden orange atoms 

 all the branches being sufficiently distinct. 



Underside : Primaries black brown, more golden fulvus 

 towards the exterior margin ; a green patch extends along 

 the whole length of the discoidal cell, and only narrowly 

 separated from the median nervure and 3rd discocellular 

 nervule by black, the subcostal or upper side of this patch is 

 irregular in outline, at the base broad and uniting with a 

 thin streak of green atoms which extends i-3rd along the 

 costal nervure ; it is then straight and increases in breadth 

 to beyond the middle of the cell, when it abruptly rises, 

 proceeds on in equal though increased breadth about 

 6 mm., to be again depressed a short distance, finally 

 rising to a point at 3 mms. from the 2nd discocellular 

 nervule, and irregularly curving down to the lower margin 

 of the patch near the 3rd ; this patch is golden green from 

 the base, becoming bluish green as it nears the 

 discocellular nervules, and contains an elongate golden 

 spot within its upper edge nearly midway ol its length ; 

 between the 3rd and 4th subcostal nervules are 2 rather 

 long patches of green and bluish green, the inner one 

 nearer to the costal nervure tetragonal, the outer one 

 rather longer and hastate in form ; a punctiform spot 

 between the 4th and 5th subcostal nervules nearest to the 

 base of these veins, with a slight indication in green blue 

 atoms of a longitudinal streak near the outer margin; 

 between the 5th subcostal branch and the 1st discoidal 

 nervule commences a broad band of blue and golden 

 green extending down the wing to the submedian nervure, 

 but more or less separated by black on each side of the 

 nervules, and also from the discocellular nervules and the 

 median branch, being thus divided into 11 patches of 

 varying size and form, the inter marginal black border 

 being nearly equal in width from the anal to the anterior 

 angles, and from 3 to 5 mms. in breadth ; the 1st of these 

 between the 5th subcostal and 1st discoidal nervules 

 occupies the whole width to within a short distance of the 

 1st discocellular nervule, and is interrupted beneath by a 

 long irregular oblique spot of black ; between the 1st and 

 2nd discoidal branches, the green is as broad as the 

 enclosed space, and is divided almost midway by a large 

 hastate black patch ; between the 2nd discoidal and the 

 1st median nervules the green is also nearly equal in 

 breadth with the enclosed space, separated by a rather 

 less broad lunate black patch, the lower division of the 

 green containing a black indentation from the dark patch ; 

 between the 1st and 2nd median branches the green is so 

 much more separated from the nervules and nervure by 

 the black, and so definitely divided into two parts, the 

 inner one nearly three times as large as the outer, as to 

 become independent patches or spots — the inner being 

 rectangular, slightly curved at the apex, the outer sub- 

 quadrate, but slightly curved at the apex ; between the 

 2nd and 3rd median nervules the inner green patch is 

 separated still more by black from the veins, is irregularly 

 rectangular, slightly crescentic at its base, and divided 

 broadly from the lower patch \vhich is subquadrate ; 

 between the 3rd median nervule and sub-median nervure 

 the greater portion of the space is occupied by the golden 

 green, divided nearest to the outer margin by black, the 

 lower part of the largest division being sharply dentated, 

 the upper part of the smallest also dentated, so that the 

 black between takes a zigzag form — a few scattered green 

 atoms uniting the two divisions of the green at the point 

 nearest the sub-median branch ; a long brown line runs 

 from the base of the interno-median nervule 2-3rds 

 through the larger division of the green patch terminating 

 in an elongated club-shaped spot at about 3-4ths of its
