among the Pseudo-Deltoids and of Hydata, Amilapis, and such-like genera of Macariidae. 
Without a complete study of the whole of the genera in each family, it would be impossible 
to arrive at a satisfactory conclusion on this point. 
RUMIA, Dup. 
Rumia sulphurea. (Plate CXIV. fig. 6.) 
Euiiiia sulphurea, Butler, Ann. 6f Mar/. Nat. Hist. ser. 5, vol. vi. p. 123. n. 24 (1880). 
Primaries above bright sericeous sulphur-yellow, mottled with grey j the base of costa, 
two subbasal bands diverging from one point at the inner margin and (with the costal border) 
forming an irregular annulus, the centre of inner border and a discal series of irregular 
ill-defined spots decreasing in size from inner border to costa, an irregular reniform spot, and 
a few small ill-defined spots on the costa ferruginous : secondaries paler yellow, with a small 
dark-brown discocellular spot ; a series of small grey dots beyond the middle of the disk, 
indistinctly united by a slender undulated line of the same colour ; external area, particularly 
towards the anal angle, mottled with ferruginous : thorax, bright sulphur-yellow ; shoulders 
and palpi ferruginous ; abdomen paler. Under surface bright sulphur-yellow ; mai'kings 
paler than above. Expanse of wings 44 millim.

OXYDIID^. 
This family differs from the Ennomidse principally in such characters as separate the 
latter from the Urapterygidae ; the wings, instead of being angulated, are rounded, and the 
apex of the primaries is acute and often projecting beyond the outer margin, rendering the 
wings more or less falcate. In these characters the family corresponds closely with the 
CEnochromiidae, with which (as wxll as with the two other groups above mentioned) it has 
been confounded; but the absence of a radial vein in the secondaries at once distinguishes it 
from that family. 
LITBADA, Walk. 
Litbada sericaria. (Plate CXIII. fig. 7.) 
Litbada sericaria, Waller, Cat. Lep. Het. Suppl. v. p. 1571 (1866). 
Form of Oxydia : wings sericeous, with a slender oblique silvery-white line, edged with 
brown from apex of primaries to just below the middle of abdominal margin of secondaries ; 
the ground-colour up to this line greyish testaceous and beyond it yellowish brown : 
primaries with a second undulated partly white-edged brownish line across the basal third : 
body testaceous, the thorax pale, the abdomen greyish. Wings below transversely and
