8. Genus: Cosscclia Wkr. 
This Genus was created for 3 species, that in wing contour and arrangement of markings are closely 
like Chandica, but neuration of hindwings differs somewhat. Veins 6 and 7 arise separately and not from a 
point. Type: erateinalis Wkr., of which, as is also the case in the other two species, only one specimen is known. 
C. hyriodes limps. Differing from quadripennis (39 i) by the absence of the indentation above the lobe 
on hindwings. Forewings dark brown. A small yellow spot with an adjoining pale line at base. In centre of 
costa a small yellow triangle with a second one adjoining and below this a black streak and a pale line. At lower 
angle of cell a few black dots with some more below. A yellow streak at inner margin. Near apex a yellow 
patch with 2 dots underneath, the latter on black ground. Hindwings dark lilac, somewhat brownish at inner 
margin. 16 mm. One from the Philippines. 
C. semiflava limps. (40 a). Forewings brownish red, darker behind the centre. The edge of the dark 
area proceeds outwards to nervure 6, it is angulated there and vertical from vein 2 downwards. Marginal area 
yellow with faint red outline on its inner edge, then turning towards anal angle. Hindwings pale brown, widely 
pale yellow at margin. In the only $ known the lobe at nervures 3 and 4 is only faintly developed. 18 mm. Borneo. 
C. erateinalis Wkr. Forewings very like those of quadripennis (39 i). The yellow patches on forewings 
narrower with a longer point inwards. Outer line more distinct anteriorly, proceeding as in quadripennis. The 
yellow spot in centre of outer margin narrower and shorter. Hindwings differ more considerably, white, widely 
brownish red at anal angle. The lobes very long and narrow. 20 mm. Y<$ from Borneo. 
9. Genus: Titulcfa Wkr. 
The species of this Genus are mostly of silvery white colouration, which is characteristic. Neuration 
of forewings is completely abnormal. Vein 3 arises far anterior to 4 and 5, veins 8+10 with very long stalk. 
Vein 9 is absent. In hindwings vein 3 + 5 stalked. Type: eximia Wkr. Nearly all the species are described 
from Borneo. 
T. argyroplaga Hmps. (40 a). Forewings yellow-brown at costa and outer margin, otherwise lilac-brown 
with silvery white spots. A large spot at inner margin near base; a longish small sjmt below centre of costa; 
a large and 2 small spots below apex, close before outer margin. Hincfwings white. In $ the much larger spot 
below centre of costa extends to inner margin, the uppermost marginal spot is wider. 20 mm. A pair from Burma. 
T. eximia Wkr. (40 a). The much suppressed ground colour of forewings is dark red-yellow. A small 
triangular silvery white spot at base on inner margin. The triangular central spot with its point below costa, 
very wide towards inner margin. Besides there is an oval subapical spot. Hindwings white. In $ the central 
spot is edged with black. 20 mm. Borneo. 
T. confictella Wkr. (= queusta Swh.) (40 a). Similar to eximia. Orange brownish. The silvery basal 
spot is more pointed, extending further tow r ards costa. The central spot is rectangular, somewhat oblique, 
extending from inner margin almost to costa. Apical spot smaller, triangular. Hindwings white. 20 mm. 
Described from Borneo, but also found in Malacca. 
T. rufimargo Hmps. (40 a). This and the following species are less white. Forewdngs ochreous brown 
and red-browm. The silvery spot at base, is similar to eximia. The point of the narrower central spot is bent 
towards the base. The subapical spot is approximately quadrate with one point to apex. The white hindwings 
have wide pale brown margins. 20 mm. Borneo. 
T. meterythra Hmps. (40 b). Forewings pale greenish yellow. At base 2 white spots the one below the 
other. The inner line is white, vertical, stout; the outer line widely excurvecl below costa, then parallel and close 
to the outer margin. The intermediate space dark brown. Hindwings pale brown. $ 20 mm. Borneo. 
T. javensis Warr. One of the only species, not found in Borneo. Forewings almost identical in o 
and $ with those of argyroplaga. Costa is more reddish vel!ow r at base, the yellow patches suffused with olive. 
Subapical spot is conjoined by a streak with anal angle, posteriorly the margin is olive-yellow. Hindwings in 
both sexes olive-brown. Java. 
10. Genus: Ariolica Wkr. (Chionomera Etlr.) 
Palpi long and slender. Wings wide. On forewings vein 10 + 8 + 9 stalked. An appendicular cell is 
absent. In hindwings vein 5 arises from centre of disco-cellular. Veins 6 + 7 with short stalk. Type: lineolata 
Wkr. This and the 4 other species occur in our territory, 2 are palaearctic. Some of them resemble the Tit ulna 
species. 
A. triangulifera Mr. (40 b). This species differs considerably in the marking from the others. Besides 
on hindwings vein 8 anastomoses more extensively with the cell. At base the costa protrudes considerably.
