territory on the Kasyr river. Of bicaudata Mr. which occurs on the palaearctic boundary in Kashmir and 
is also distributed over southern China, extending northwards to Ningpo and the Yangtse'kiang, two further 
forms are illustrated — rufimargo Warr. and fuscifrons Warr. in Volume 10, pi. 59 d. These very probably 
belong to the group of exornata forms, although they have not yet definitely been found on palaearctic 
territory. 
Genus: Decetia Wkr. 
Of this mainly Indian Genus one today knows about 2 dozen species, which remind one strongly of 
certain american Geometridae species. Besides other species the Genotype numicusaria Wkr. from N. India 
is illustrated in \ ol. 10, pi. 58. — Of palaearctic species are classified here: 
D. argentilinearia Leech. In Vol. 2, p. 196, this was classified under Mimozethes as a Drepanidae. The 
illustration there on pi. 48 a is very good. In Vol. 10, p. 580 it is described from the Indian territory (For¬ 
mosa, where it is not rare). Besides this, 2 other species that are best known from Indian territory, occur 
in the south east of the palaearctic region, viz: 
D. violacearia Leech. This is almost as large as numicusaria (Vol. 10, pi. 58 e) and of very similar 
grey colour with violet shade, wings brown anteriorly and towards the margin, all wings with dark central 
spot and with a brown line that extends from apex of forewings to centre of inner margin and continues 
over the hindwings to the inner margin, so that a superficial resemblance is created with the (much larger) 
Dalima acutaria (Vol. 4, pi. 16 h). West China. — Further 
D. lilacinaria Leech. Ground colour dark brown with violet hue, wings with golden brown colour¬ 
ation in outer area; forewings with central spot and 2 parallel transverse lines, of which the outer one is 
angulated below the costa and extends to inner margin of hindwing. Somewhat larger than previous species. 
Similarly from West China. In regard to this and previous species, compare also Vol. 10, p. 280. 
Genus: Paradecetfa Swh. 
In regard to this Genus and the species classified here of which one occurs in North India and 2 in 
N. W. China, please refer to what is said in Vol. 10, p. 581. 
P. vicina Swh. Size as previous species. Grey with violet hue. The transverse line which extends from 
the projecting apex of forewings to middle of inner margin of hindwings is crimson-red. Compare also Vol 10 
p. 581. ' ’ 
P. myra Swh. is also of the same size as lilacinaria (36 mm). Buff with darker dustings. Oblique 
line brown. In this and previous species there is a white cell spot on each wing. West China.
