1. Aedemoses haesitans, sp. n. (Tab. V. fig. 21.) 
Antennae and Palpi pale fawn, the latter tipped with rust-brown. Head and Thorax pale fawn. Forewings 
pale fawn-ochreous, with an oblique fawn-brown line from the commencement of the costal cilia, 
descending straight to the tornus; a minute spot of the same at the end of the cell, another on the cell 
half-way between this and the base, a third in the middle of the fold; from the plical spot a line of 
brown scales descends obliquely outward to the dorsum and is diffused along it nearly to the tornus, but 
not conspicuously ; there are a few small brown dots around the apex and termen at the base of the 
pale fawn cilia. Hwp.al.12 mm. Hindwings fawn-brownish; cilia pale fawn. Abdomen fawn. Legs 
pale fawn-ochreous.

A small and inconspicuous species, but easily recognised by the oblique transverse 
line which cuts off the apical area. 
CATARATA, gen. n.

Type: Catarata lepisma Wlsm. 
Antennae 3, Q simple. Labial Palpi long, recurved, with appressed scales; terminal joint shorter than 
median. Mawillary Palpi short, converging. Haustellum well-developed. Head loosely scaled. 
Thorax smooth. Forewings narrow, elongate, costa slightly arched at base, apex rounded, termen 
somewhat oblique, tornus evenly rounded: neuration 12 veins; 2-3 stalked, 4 out of their stalk; rest

1. Catarata lepisma, sp. n. 
Antennae smoky, dull brownish ochreous. Falpt whitish ochreous, dusted with fuscous, a fuscous band before 
the apex of the terminal joint. Head and Thorax whitish ochreous, shaded above with smoky fuscous. 
Forewings whitish ochreous, much sprinkled and smeared with smoky fuscous; in addition to some 
general irroration, a costal shade, extending from one-fifth to beyond the middle, is followed by another 
costal patch, or shade, before the apex, from which arises, on its outer side, a series of fuscous spots, 
continued around the apex and termen, and from its lower edge a second series, more or less confluent, 
bowed outward and reverting to the dorsum about the tornus; there are two dark shade-patches also 
on the dorsum, one before and one beyond the middle, other scattered dark scaling extending across the
