1. Psilocorsis argyropasta, sp.n. (Tab. IV. fig. 8.) 
Antennae pale fawn-ochreous, delicately banded above with brown on each joint. Pali slender, recurved, 
smooth ; pale ochreous, with a black line along their undersides to the apex. Head and Thorax pale 
ochreous, the latter much shaded with brown. Forewings pale fawn-ochreous, delicately striate trans- 
versely with brown throughout, the striae becoming somewhat confused obliquely across the end of the 
cell; termen narrowly dark brown, tending to break into spots near the apex; cilia brilliant metallic, 
changing from silvery to golden. Eap.al. 14 mm. Hindwings and cilia pale greyish ochreous, with a 
narrow brownish marginal line. Abdomen yellowish brown. Legs whitish ochreous ; the anterior and 
median tarsi shaded with brown.

The metallic cilia and conspicuous transverse striations render this small species 
easy of recognition ; it is most nearly allied to 5801 guercicelia Clms. 
9. Psilocorsis indalma, sp. n. 
Antennae brownish ochreous, with three black lines along their basal third, two of which only extend along 
the basal joint, the upper one commencing immediately beyond it; the first two coalesce, and all are 
broken beyond the basal third into blackish annulations extending to the apex. Palpi ochreous, a black 
line along the lower side of the median joint, and two black lines along the terminal. Head brownish 
ochreous. Thorax tawny brownish. Forewings brownish ochreous, profusely sprinkled with fuscous, in 
a somewhat striate transverse form, the whole having a slight vinous suffusion ; a fuscous spot lies 
at the end of the cell, and a smaller one on the cell half-way to the base; from the lower angle of the
