DIASEMIA LEUCOSALIS sp. noy. (PI. I, Fig. 9). 
Primaries light yellow with slight sprinkling of brown scales and veins more 
or less marked in brown; basal portion of costa shaded with purple-brown, 
t. a. line fine, brown, outwardly rounded on vein 1; orbicular round, more or 
less filled with purple-brown; reniform a quadrate purplish blotch the lower 
portion of which is usually lost in some brown scaling and the upper portion 
almost attains costa; a small quadrate hyaline white spot separates the reniform 
and orbicular; t. p. line brown, straight from costa to vein 5, then rounded in- 
wardly to base of vein 2 and inwardly oblique to inner margin near t. p. line 
with slight outward curve across vein 1; the remainder of the wing beyond the 
t. p. line is largely deep purplish, mixed with brown, leaving three small yellow 
triangular spots next t. p. line between veins 5 and 8 and a narrow yellow band 
on outer margin below apex, divided into spots by the brown veins and usually 
not extending much below vein 5; below the cell the purple suffusion is bordered 
inwardly by a darker line extending from base of vein 3 to inner margin par- 
allel to t. p. line and leaving a narrow band of clear yellow between the two 
lines, divided into patches by the brown veins; apex of wing shaded with brown 
without purple tinge; terminal dark line; fringes brown in basal half, whitish 
outwardly. Secondaries pale whitish-yellow with broad brown outer border, 
narrowing towards anal angle; a minute discal dot and a median dark line from 
cubitus to inner margin of wing parallel to inner margin of terminal band; 
fringes as on primaries. Beneath whitish with the markings of the upper side 
reproduced in smoky. Expanse 15-17 mm.

DIASEMIA ZEPHYRALIS sp. nov. (Pl. I, Fig. 10). 
Palpi blackish, whitish beneath at base; head and thorax, sulphur-yellow; 
primaries sulphur yellow shading into orange-yellow terminally, costa to reni- 
form purple; orbicular oval, reniform figure of 8, both filled with purple and 
attached to costal stripe; traces of a t. a. line and a median line in a few pur- 
plish dots above inner margin; t. p. line deep purplish, finely dentate, almost 
straight below costa, bent sharply at right angles along vein 3 to below reniform 
and then again at right angles to inner margin, the sinus thus formed filled 
with a purple suffusion which extends narrowly upwards along outer edge of 
t. p. line and broadens out below costa to a second patch; fringes yellow. Sec- 
ondaries similar in color to primaries; a subbasal dark line only prominent 
above inner margin, a small discal dot and a subterminal line continuous with 
the t. p. line of primaries and squarely exserted between veins 3 and 6; a pur- 
plish suffusion beyond this line especially prominent from vein 3 to anal angle.
