185. Omphisa repetitalis, nov. spec. (PI. XIX., 

 figs. 6, 6rt). 



Four specimens of 38 — 40 mm. expanse. 



Tins species has all the characters of the gemis Omphisa, Moore, 

 ' Lepidoptera of Ceylon,' part 12, p. 317 ; in fact, it displays 

 them even more decidedly than the hitherto solitary typical 

 species, for the acute apex of the fore wings is more produced, and 

 the hind margin of the fore and hind wings much more distinctly 

 bent on vein 4, especially that of the latter. In other respects it 

 is also very alike to anastoniosalis, Guen, (Pionea), Delt. et Pyr., 

 p. 373, illisalis, Walker, Lederer, Beitrag, pi. 9, fig. 12, and Moore, 

 I.e., p. 318, pi. 183, fig. 4; colour and markings similar: the 

 principal differences consist in the hind margin of the wings not 

 being denticulated, the cilias being only streaked with dark brown 

 on the veins 3 and 4 of both wings, not generally, and the hind 

 margin of posterior wings being blackish from the apex till vein 5, 

 gradually narrowing downwards, and with a graphitic lustre in the 

 middle. Lederer placed anastomosalis in Botijs, but its generic sepa- 

 ration by Mr. Moore is quite justified, and the proper place of Om- 

 phisa, Moore, in Lederer's System, is between Gen. 115, Megastes, 

 Guen., Led., and 116, Mecjapliysa, Guen., Led. Labial palpi 

 formed as in anastomosalis, a little stouter, pale yellow, outwardly 

 brown ; maxillary palpi very distinct. Antennae distinctly ciliated, 

 somewhat serrated (they are setaceous in anastomosalis). Thorax 

 sordid ochreous brown ; abdomen too, but clearer, and with distinct 

 pale ochreous yellow spots on basal half. Ground colour of upper 

 side of wings a pale whitish ochreous yellow, as in the allied 

 species, in tlie same way mixed with luteous brown on the fore 

 wings ; only the costa, except on the basal and apical fourths, 

 which are deep brown, and the hind margin posterior to a double 

 denticulated second transverse line from veins 3 — 8 are pale ; first 

 transverse or antemedial line strongly curved, single, dark brown, 

 on the outside of the upper part with a nearly black shade, which 

 becomes wider downwards, and almost covers a small, hyaline, 

 orbicular mark ; reniform mark oblique, quadrate, elongate, also 

 hyaline, brown-bordered ; below it one smaller hyaline spot at the 

 base of cell 2; the inferior part of a deep brown discal line is 

 visible below the spot ; second transverse line described above, its 

 inferior part indistinct, lost in the brown suffusion, which, below 

 vein 4, extends fully to the hind margin ; vein 7 is dark brown, a 

 thick marginal line also, the cilia; pale yellow, except at the apex 

 and anal angle, where they are dark brown ; two transversal brown 

 streaks are also found at the extremities of veins 3 and 4. Hind
