more produced, the distal margin curved and the anal angle rounded; these may be separated as elegans elegant, 
subsp. nov. (49 b). — In ab. diluta ab. nov. (49 b) the dark greyish-brown shading is faded and sometimes hardly diluta. 
recognisable. 
I. examplata sp. nov. (49 b). The <$ resembles semirufa elegans (49 b) from which it differs as follows: examplata. 
the shadow filling the median area is brown and narrows down at the costal margin before the apex; the spots 
in the cell mostly all show a light centre, the distal line is generally thicker, particularly in the hindwing, where 
the white spot on the lower cell-angle is double and the lunulae of the distal line are partly like ocelli. The 
$ is much larger, quite yellow, except the brown subapical marginal marking in the forewing. All the lines 
and markings are clear and dark. On the hindwing the distal line and the cellular spots form a kind of entangled 
chain. In the Tring Museum there are 3 from Mt. Goliath (type) and Angabunga River (New Guinea) and 
Rock Is., and many <$$ from the Angabunga, Mambare, .Biagi, Ninay Valley, and Mt. Goliath (type) from New 
Guinea; I from Rock Is. The couple from this island is much smaller and deeper yellow, with a more intense 
marking and colouring. 
I. cervina -sp. nov. (49 d). Forewing rosy fawn coloured with a slight violet gloss; a dull silvery marking cervina. 
at the upper branch of the discocellular and another one at its lower end, situate on a brown cloud; the 
proximal and distal lines are brown, feeble; below the costal margin 4 dark brown subterminal spots. On the 
lindwing the two hues at the hind-margin aie darker; at tbe lower cell-angle a brownish cloud enclosing an 
hndulating lustrous marking; costal area lighter, fringes of both wings brown; under surface cpiite dull yellow, 
u $ from Biagi, Mambare R. (British New Guinea), at an altitude of 5000 ft., captured by A. S. Meek in 
February 1906. 
I. tristigma sp. nov. (49 d). Forewing olive-grey; the lines are not prominent as in olivacea. In the tristigma. 
cell a brownish spot, and a large oval one at the upper end of the discocellular; at the lower end of the 
discocellular a somewhat 8-shaped cloud the upper part of which encloses a white centre. Costal margin between 
the lines clouded black; subterminal line distinct, particularly the uppermost 4 spots. Hindwing as in the 
of olivacea ; also the under surface similar. 1 $ from the Upper Aroa R. (New Guinea), taken by A. S. Meek 
in March 1903. This might really be the $ of olivacea, but the exterior is quite different. 
I. sera Warr. (49 b). Forewing dull yellowish ochreous, with indistinct markings; proximal line curved, sera. 
yellowish-red, only recognisable towards the hind-margin; a yellowish-red distal line from the costal margin 
to the centre, strongly excurved and undulating; a yellowish-red spot at the upper cell-angle and a white spot- 
edged with yellowish-red at the lower angle; a submarginal curved row r of blackish streaks between the veins, 
those behind the cell being larger and roundish: distal margin below the apex yellowish-brown. In the hindwing 
the 3 lines are only marked at the abdominal band. Head, thorax, and abdomen coloured like the wings, 
excepting the vertex and the upper portion of the face, which are of a bright reddish yellow. — suffusa ab. nov. suffusa. 
(49 b) is an aberration in which the whole forewing, sometimes also parts of the hindwing are coated with a 
dark red-brown. — Described from Fergusson Is., but occurring also in New Guinea. Distinguished by the 
absence of lustrous scales. 
I. septempunctata Warr. (49 b). Forewing abundantly yellowish-brown excepting tbe base and a septempunc- 
spot at the anal angle. Proximal line brown, forming a darker spot below the median; distal line directly 
behind the centre, excurved and bent, on the submedian fold notched towards the spot on the proximal 
line; 1 white spot in the cell and 2 at its end, the spot at the lower end being the largest. Before the 
margin behind the cell 2 large white oval spots, proximally bordered with black lunulae, 2 smaller white spots 
obliquely above them and 4 blackish dots below them. Hindwing quite yellow', with a basal and an undulating 
distal brownish line and a sub marginal row of blackish dots; discal spot large, whitish, surrounded by brown. 
Under surface quite yellow; forewing with a brownish subapical spot and the dark apex of a distal line. Face, 
vertex, palpi, and forelegs of a bright yellowish-red; thorax and abdomen yellow, lined with reddish-yellow'. 
Khasia Hills (Assam). — In a form from Travancore, pervasata subsp. nov. (49 b, by mistake as provasata) pervasata. 
the brow'n filling in the discal area of the fore wing is continued through the hindwing though less intensely, 
the marginal area with the dark subterminal spots in the centre remaining broadly yellow. On the forewing 
there is before the subterminal line a distinct yellow band; on the forewing there is no white spot in the cell 
and on the hindwing only 1 instead of 2. 
1. rubromarginata Leech (49 c and Vol. II, pi. 48 b). Forewing deep yellow with a broad brown marginal rubromargi- 
shadow occupying one third of the hind-margin and narrowing down towards the apex and enclosing at is 
proximal edge some dark spots above the hind-margin. Hindwing yellow. Described by Leech from Pu-tsu-fong 
in China, but occurring also near Yatong in Tibet and Tonglo in Sikkim. 
I. obliquitaenia sp. nov. (49 c). Forewing straw-coloured; lines free, yellowish-red, the proximal obliquitae- 
line obliquely distally and curved above and below the median; the distal line formed of small strong crescents, nia - 
dentate, almost vertical; from the apex almost to the centre of the hind-margin a thick grey oblique streak 
which is met by a median line from the centre of the hind-margin, forming a bend with it after its angulation;
