somewliat smaller and more shining in appearance, the 
ground-colonr being more unmistakably white. 
Paedisca hiplagata, sp. n. (PL XII. , fig. 7.) 
Antennce biciliate (less than ^) ; very pale fawn, the basal 
joint, straw ochreous. Palpi projecting more than the length 
of the head beyond it ; pale straw-ochreous, shaded along the 
sides with fawn-brown. Head and Thorax straw ochreous. 
Forewings rather wide, the costal margin very slightly arched, 
apical margin convex ; pale straw ochreous with two small patches 
of fawn-brown scales, the first above the middle of the dorsal mar- 
gin, pointing obliquely outwards, reaching to the lower edge of the 
cell ; the second at the end of the cell, tending obliquely outwards, 
from near the costal in the direction of the apical margin above 
the anal angle ; these patches are faintly outlined by shining 
white scales, extending towards the anal angle, but scarcely distin- 
guishable from the pale ground-colour of the wing, in which there 
is a certain admixture of the same ; cilia pale straw ochreous, 
tending to whitish on their outer half. Exp. al., 24 mm. Hind- 
wings pale reddish brown ; cilia shining white. A.Momen 
whitish ochreous. Legs whitish.

Psedisca fuscosparsa, sp. n. (PI. XII., fig. 8.) 
Antenn(B biciliate (more than ^) ; pale cinereous. Palpi pro- 
jecting the length of the head beyond it ; whitish ochreous. 
Head brownish ochreous. Thorax whitish ochreous, the tegulse 
spotted with greyish fuscous scales. Forewings moderately straight, 
not much widened outwardly ; whitish ochreous, streaked and 
sprinkled with brownish fuscous scales, with a slight fawn-brown 
suffusion along the middle ; the brownish fuscous scaling is more 
noticeable about the middle of the wing-surface where, in the type, 
it assumes the form of an ill-defined narrow band enclosing the 
outer portion of the cell and resting on the fold at either extremity ; 
immediately below the costal margin are a number of small 
irregular brownish fuscous spots, and a line of these runs parallel 
to the apical margin at a short distance from it, preceding a few 
similar spots at the apex and along the margin itself ; below the 
fold are also a few small brownish fuscous spots and the paler 
fawn-brown suffusion is also here somewhat noticeable ; cilia 
whitish ochreous touched with fuscous at the edges. The fore- 
wings are pale margined on the underside, the pale costal band
