rntroductien
In this paper two new species ofthe genus Ctenognqphos Prout will be described from
the Himalayas. They are closely related to C eolaria (Guenee )th,e type species ofthe
genus. One of them was collected from India and Nepal, and the other from Kashmir,
In my previous papers (Sat o19,94, 1998, 2000), the following four species were record-
ed from Nepal as members of Ctenognophos: cuprearia (Moore) ,zelompus Inoue,
eolaria (Guenee )o,bteetaria (Walker ).Besides C methoria Prout was recorded from
E, Nepal by Inoue (1982 :186), Here, C paerfita (Butle rwi)ll be added to the fauna
ofNepal.
The fbllowing acronyms are used to indicat ethe location of the specimens. BMNH:

Length of forewing 21-36 mm, wingspan 35-43 mm. Both wings variable in colour
and maculation, especially on underside (Fig 5s, 7 & 9). Mere similar to obtectaria
(Fig s10-ll) than te eolaria (Figsl- 2)in having wings without yellowish tint.
Differen tfrom obtectaria in the fo11owing characteristics. Male antennal pectinations
shorter. Both wings greyish brown, net tinged with purple or red; rnarkings as well
in obtectaria, but tending to be less defined.
Male genitalia (Fig 2.4). Most similar to those of eolaria (Fig 2.8) as fo11ows , Left
valva with an oblong mass of spines and right valva with several long spines, as in
eolaria, but valva narrower, ventral spur longer s,pines on lef tvalva much shorter than
in eolaria, Easily distinguishe dfrom those of obtectaria (Fig 2.5) by a large rmass of
spines on left valva.
Female genitali a(Fig 2,9). Similar to those of obtectaria (Fig 3,0), but a triangular

the holotype.

I also examined the fbllowing type and non-type specimens and their genitali aslides
