Central line diffuse, oblique. Reniform stigma large, brown and round. Outer line blackish proceeding below 
costa widely outwards, with points on the veins, incurved below nervure 5. Submarginal line black, outwardly 
green and white. Obliquely brown at apex. Hindwings creamy white, central lunule and margin brown. 
32 mm. Java. 
The following species are brownish. 
R. pratti B.-Bak. (31 f). Forewings lilac-grey-brown, reddish yellow at base on inner margin. Orbicular pralli. 
stigma black punctiform, reniform small with black surround. Somewhat greenish in centre of inner margin. 
Outer line double, white, straight from %’s of costa to 3 / 5 ths of inner margin with wide dark brown outer edge. 
Submarginal line undulate, dark, from nervure 5 to inner margin, with white streak above. Hindwings brownish 
white, widely brown at margin. $ 36 mm. New Guinea. 
R. diversipennis Wkr. (39 f). The species is easily recognisable by the pronounced white line at lower edge dh-cr&ipcn- 
of cell, below which it is dark red-brown. Ground colour lilac-grey to the lower edge of cell. A brownish white 
spot on inner margin at base. In cell a black dot, at disco-cellular a red-brown spot. The outer line pale with 
dark edging on both sides, bending inwards to nervure 3, then obliquely and very indistinctly inwards, termin¬ 
ating in a white spot at inner margin. Submarginal line delicately white, angulated outwards on nervure 7 
forming a spot, then parallel to outer margin. Hindwings as usual. 32—35 mm. India, Malacca, Borneo, Sumatra. 
R. basalis Mr. (39 e). Pale reddish brown, paler in centre of costa and in middle of outer margin. The basali*. 
usual white spot at base. The inner line indistinguishable. Reniform stigma brown and round. An oblique dark 
shade from costa, via the reniform stigma to centre of inner margin. The outer line indistinct, double, pale in¬ 
wardly, excurved behind the cell, then inwards and dentate. At margin 2 black streaks below apex and one 
at nervure 1. Submarginal line delicately white, indistinct. Hindwings as usual. On forewings costa and inner 
margin are occasionally somewhat green. 34—38 mm. India, Ceylon, Hongkong, Formosa. 
R. ornata Wilem. & West. Forewings yellowish, partially greenish brown on costa, yellowish red in and ornala. 
below the cell. Dark red-brown on costa at base. From apex to inner margin a diffuse brown central stripe. 
Then an oblique white streak, wide anteriorly, narrower and yellow-red near inner margin, beyond this greenish 
brown, dark brown towards apex, a white spot on inner margin near the anal angle. The outer line dark red- 
brown, undulate, somewhat interrupted, with white dots on nervures 2—6. Hindwings as usual. 32 mm. 
Philippines. 
R. kebea B.-Bak. Forewings olive-brown, somewhat dusted with greenish. At base the usual white spot, kebea. 
Reniform stigma greenish with white surround. Below this a white streak with darker outer edge. Behind the 
stigma a pale ochreous greenish stripe with delicate inner white edge, almost conjoined with the dark apical spot, 
that has a white lower edge. There is a dark submarginal row of dots with white inner edges. Hindwings creamy 
white, the margin widely dark. The $ is paler, the white streak below the reniform stigma is absent . $ 42—44 mm. 
New Guinea. — According to E. Prout the form denoted by Hampson as “ cebea ” is in fact owgarra. 
R. owgarra E. Prout. (= cebea Hmps.) (39 f). The $ is somewhat smaller than in kebea. Costa of fore- owgarra. 
wings is white almost to the apex; there is no white dentation in the black spot below apex. The pale basal spot 
is smaller and more obliquely edged. The white stripe before the outer line is less straight and regular. The outer 
line is undulate rather than dentate. Marginal dark band on hindwings is somewhat narrower. In $ the pale 
basal spot is suffused with brownish green. The pale spot on costa outwardly extends further down than in 
kebea. Outer line is somewhat steeper at inner margin, so that it is about 5 mm distant from the inner line, 
whilst in kebea the distance is about 2 1 mm. 
R. olivens B.-Bak. (39 f). Forewings dark olive-brown. The pale basal spot is cut off steeply. Inner oliven.s. 
margin is deeper brown, beyond same a fine white streak to outer line. The inner line indistinct, punctiform. 
Reniform stigma small, round, white. Outer line black, edged with white outwardly, dentate, vertical below 
costa, then incurved and vertically to inner margin. Costa white from reniform stigma to submarginal line. The 
latter is black, dentate and parallel to the outer margin. Hindwings as in kebea. $ 32 mm. New Guinea. 
R. literata Mr. (39 f). Forewings olive-brown. The pale spot at base edged by a very oblique white line. Uteraia. 
The pale inner line is indicated in an angle below the cell. Reniform stigma is small, triangular with pale edge. 
The outer line is white and straight, turning delicately inwards at inner margin. Submarginal line whitish with 
dark brown inner edge, punctiform in centre, excurved below nervure 7, beyond this red-brown at apex. Hind¬ 
wings yellowish, widely brown at margin. albistriata Pagst. from Borneo, has a bold white outer line, beyond albistriata. 
this it is as dusky as the ground colour to the submarginal line. Submarginal line white, not interrupted, angul¬ 
ated outwards at nervure 6, inwards at nervure 5 and excurved below. There are no dark spots. Distallv white 
between nervures 5—7. The veins are white before the outer line. Hindwings darker at base. 32—35 mm. 
India, Ceylon, Amboina. 
R. avola B.-Bak. (39 f). Forewings lilac-brown, somewhat yellow-green on costa behind centre. The avola. 
dark inner line is indistinct, incurved to the pale basal spot at inner margin. A dark undulate central line pro¬ 
ceeding outwards into the cell, then vertically. Reniform stigma greenish with dark surround. The outer line 
black, finely dentate, about parallel to older margin, slightly incurved on the submedian fold. Proximally widely 
white to central line. Black spots before the apex, from which the delicate black submarginal line arises. Hind-
