rays are deeply concave, and consequently their termi- 

 nals are much raised, it will be manifest that the depres- 

 sion mentioned above allows space for the terminals to 

 fit in conveniently, so that when the pouch is closed, as 

 it nearly always is, the abdominal portion of the wing 

 should lie as nearly flat as the rest of the wing ; 

 the two edges of the fold, i.e. where they meet when 

 the fold is quite closed, are within nearly white, especially 

 towards the base of the wing. The peculiar form of the 

 fold when nearly open will be understood by reference to 

 plate 57 figs. 5, 6.* On the under surface of this fold the 

 abdominal fringe of cilia or hairs, which are black and 

 long, all start from the outer part of what I call the hinge 

 of the fold, down the whole line of the inner margin, so as 

 to enclose nearly the whole of the subdorsal portion of 

 the abdomen of the insect. In the 2 2 of this genus the 

 abdominal fringe hairs are much shorter and fewer in 

 number.] 



Undersurface : The golden silky yellow, and all the 

 dark areas of the wing are exactly the same in position 

 and outline as above, but on the sub-median yellow area 

 is a small sub-anal orbicular brown spot, within a patch 

 of sparsely-dusted black atoms ; the anal angle is black, 

 and the abdominal margin warm brown-black ; the fringe 

 lunules, piceus. Eyes, nitid brown-black, and very 

 prominent, with no light margin ; villose tuft of the head 

 velvety black ; antennae black, and stouter than in some 

 species. 



Thorax velvety black : pronotal collar red, but almost 

 concealed in some examples ; underside of thorax black 

 with the usual pectoral red patches, but varying in extent ; 

 legs black. 



Abdomen golden yellow, with the dorsum dark warm 

 brown, the middle segments with a longitudinal fawn- 

 coloured stripe, and all the annulations expressed in 

 yellow ; the usual lateral sub-dorsal black dots ; and 

 valves light fawn-coloured with a dorsal triangulate brown 

 mark. 



Length of costa of primary wings 6g mms. ; of posterior 

 margin 54, and interior margin 36 mms. ; of secondary 

 wings, width 34 and length 43 mms. Length of antennae 

 or abdomen 27, and of the thorax with the head 18 mms. 

 Articulations of the antennas 38. They are sometimes as 

 many as 42 and 44 in some examples from the same 

 locality. [See plate 56, figs. 1 and 2]

2 . Anterior wings black smoky brown, with the outer 

 5th of the cell buff or creamy white, blended into the dark 

 part of the cell by dark atoms ; the adnervular discal 

 rays are of the same light tint and coalesce so as to form 

 a continuous light area only divided from the distal part 

 of the cell by the nervures — thick rays extending nearly 

 from the subcostal nervure to the 2nd median nervule, 

 and their terminals to a short distance of the posterior 

 margin ; the rays are graduated towards the posterior 

 margin by smoky brown atoms till their terminals become 

 greatly subdued, so as to nearly melt into the general 

 brown of the disc ; on the 3rd median nervule is a short 

 rudimentary white adnervular submarginal ray, dusted 

 with fumose atoms, and two others above and below the

submedian nervure. The veins are all sufficiently stout 

 and prominent ; the fringe lunules are creamy or buff- 

 white. The 3rd subcostal branch commences a little 

 beyond the cell ; the pseudoneura are fairly distinct, the 

 3rd terminating with a prominent black interrupting spot 

 on the discocellular nervure. 



Posterior wings, golden yellow ; the basal end of cell, the 

 base of the wing, and costal and subcostal part of the 

 wing the same brown as that of the anterior wing, inter- 

 rupted by a small sub-apical yellow mark ; the posterior 

 marginal black border projects into the yellow area of the 

 wing in a series of long adnervular cones, surmounted by 

 large black subcordiform spots, which are often connected 

 with the cones themselves, and are 6 in number — the 6th 

 being indeterminate in shape, only separated from the 

 border by a small patch of yellow, and dusted with white 

 atoms ; the interior margin is brown, dusted with white 

 atoms outside the submedian fold, while the yellow out- 

 side the 3rd median branch is subdued with a delicate 

 buff-white, which becomes greenish at the anal angle. 

 The fringe lunules are buff-white. The wings are strongly 

 dentate, especially at the terminals of the 2nd and 3rd 

 median nervules ; the veins intersecting the yellow area 

 of the wings are stout and deep black. Undersurface of 

 the anterior wings in all respects almost entirely similar 

 to the upper surface, with a faint streak of white atoms 

 on the submedian fold. 



The posterior wings also differ very little on the under 

 from the upper surface, except that the row of discal 

 black spots are rather larger, and more irregular in shape, 

 and are not united with the conical projections of the 

 black border as above : they are all bordered with patches 

 of white atoms : there is an orbicular black spot in the 

 yellow at the anal angle : and all the yellow spaces be- 

 tween the nervules are intersected and subdued by stripes 

 of pale white, a part of the yellow of the cell being treated 

 in the same manner. The veins are all fairly prominent. 



Head and thorax velvety black ; eyes dark castaneous 

 brown ; antennae black ; pronotal collar red — the colour 

 nearly concealed by the black ; with large pectoral red 

 patches within the dark brown ; legs stout and black ; 

 abdomen fumose brown — each annulation divided by fine 

 yellow lines, the sides and subdorsum golden and pale 

 yellow with lateral black dots, and dorsal small black 

 bars. 



Length of costa 70 mms. ; width of anterior wing 46 

 mms. ; length of hind wing 54, and width 36 mms ; length 

 of abdomen or antennae 26 mms. ; of thorax with head 

 21 mms.

2 . The posterior wing of a variety is figured on PI.

 the amount of variation from the type fig. is fairly notice- 

 able the general plan of the pattern is followed in this 

 variety. Not so, however, in the case of the interesting
