of both wings more yellow. The diagonal band behind the inner line extends to costa. There is no dusky patch 
behind the outer line. The distance between the outer line and the submarginal line seems greater. 2 45 mm. 
Philippines. 
R. calaina Zerny (obliqua Prout *). Forewings turquoise-blue merging into verdigris-green at outer 
margin. Centre of inner margin dark brown. The inner line extending from a triangular dark spot, turning into 
verdigris-green, dentate, outwardly. An ochreous streak anteriorly below the cell. Reniform stigma elliptical, 
whitish with dark brown surround. The outer line arising on costa in a white spot, proceeding boldly outwards, 
then sharply dentate to inner margin, whitish with brown inner and verdigris-green outer edges. Inwardly it 
forms an acute point towards the reniform stigma. Submarginal line whitish, with wide brown inner edge, 
sharply dentate, extending widely inwards behind the cell. Hindwings yellowish, brownish at margin. $ 40 mm. 
Malacca. 
R. calainodes E. Front. This differs from calaina by the following characteristics. The green colour is 
more extensive on costa and behind the centre. Only the base is white and further the inner margin at the 
outer line, in the cell and at apex. The green patch on inner margin near the base extends in a band to the base 
at costa. Orbicular stigma is a black dot. Reniform stigma is more rectangular. The outer line is more oblique 
at costa, submarginal line on the other hand more vertical, q 38 mm. Sumatra. 
R. ocellata E Front. (39 d). Forewings pale green, inclined to golden yellow towards outer margin. 
Markings black and white. The inner line white, curving inwards from one-third of costa almost to base at 
inner margin with a wide black outer edge. Claviform stigma triangular, orbicular small, reniform stigma with 
2 black central dots. All 3 stigmata white with black surrounds. The outer lme dentate, black and parallel to 
outer margin, closely anteriorly the straight central line. Submarginal band black with somewhat dentate outer 
edge, including a few white spots and dots. Hindwings brownish with pale outer band. 32—36 mm. Borneo, 
Sumatra. 
R. sticticata E. Front. Forewings white, dusted with green and partially with yellowish brown. Markings 
dark brown. The inner line from 1/ , of costa to A of inner margin, angulated outwards below costa, inwards at 
nervure 1. with a few dark dots anteriorly. Central line a faintly excurved row of clots. Reniform stigma oval 
with dark surround and central spot. Outer line as a double row of dots, widely excurved below costa, curved 
at nervure 4 and inwards to 3 / 5 ths of inner margin. Submarginal line consists of bold brown spots with white 
outer edge and further a large apical spot. Hindwings white, margin widely pale brown. 30—33 mm. New Guinea. 
R. diphtheropsis E. Prout. The very opposite of the preceding species. Forewings black with large and 
small yellowish white spots. A row of large spots near the base to 1 :! rd of inner margin, three very irregular spots 
from Rrd of costa to centre of inner margin, a row from 3 / 5 ths of costa to anal angle and beyond that a few 
at outer margin. Among these innumerable dots and specks. Hindwings creamy white, widely blackish at margin 
enclosing spots in the ground colour. E 38—44 mm. Found at one time in fairly large numbers in the mount¬ 
ains of New Guinea. 
R. diphtheroides Hmps. (39 d). Forewings pale bluish green, silvery white at base below cell, dark up 
to the inner line. The latter dentate, sharply angulated outwards below cell, posteriorly pale brown in anterior 
part. Orbicular stigma small, white; reniform with black surround, elliptical and with black central dot. Outer 
line black, dentate, widely excurved below costa, then inwards with white inner edge. Submarginal line bold, 
black, rather dentate, excurved in centre, edged somewhat with brown outwardly. Hindwings brownish, darker 
at margin. ^ 28 mm. Assam. — Very like a very green glaum. 
R. chlora Hmps. (39 e). Forewings yellowish green with indistinct dark transverse lines. Reniform 
stigma diffuse and brown. The outer line commencing below costa, black, double, dentate, straight inwardly. 
Behind this lilac-brown to the submarginal line. Submarginal line itself black, dentate, parallel to outer line. 
Hindwings pale brown, widely dark at margin. $ 40 mm. Singapore. 
R. viridata B.-Bak. (39 e). Forewings pale green with brown patches. Inner line blaqk, dentate, slightly 
excurved in centre, green anteriorly. Reniform stigma pale green with dark surround. Central area brownish 
at costa, otherwise whitish. Outer line black, boldly excurved at costa, but obscure, then dentate and straight 
inwardly. Submarginal line black, dentate, slightly excurved in centre, brown anteriorly to the outer line. 
Hindwings white, widely brown at margin. $ 36—40 mm. NeAv Guinea. 
R. delicata B.-Bak. (39 e). Forewings white and pale green. The inner line delicate, dark, dentate, 
obliquely outwards, slightly brownish anteriorly. Orbicular stigma small, green with white surround. Reniform 
elliptical with black circumscription and central dot. Central line dark brown anteriorly, then green and in¬ 
distinct. Outer line delicately darkly dentate, uniformly curved, somewhat more upright than in viridata. Sub- 
marginal line white with dark brown inner edge, somewhat dentate, indistinct in centre. Hindwings as in viri¬ 
data. — delicatula Strd. has a brown shade on forewings near base, from costa to inner margin, behind the inner 
line. E 34 mm. New Guinea. 
R. viridescens Hmps. Forewings greenish grey-brown, somewhat diffusedly greenish below r costa, whitish 
green at base of inner margin. Inner line blackish, oblique, excurved on submedian fold, then turning inwards. 
*) Later Prout withdrew the name obliqua in favour of calaina when he was describing calainodes. As the descriptions 
do not entirely tally, we are giving both.
