33. Genus: Karacus Mr. 
The genus consists of a few very neat species inhabiting the Indian Continent and the Philippines. 
They are most conspicuous by the great width of the forewing with the steep long distal margin, and the broad 
and long hindwing. The £<$ above often exhibit lustrous bluish-grey scales; head and thorax are broad, but 
the abdomen is rather long and slender. Hind tibiae with two pair of spurs and fringed with hairs. Most of 
the insects seem to inhabit the mountains and to be confined to mountainous districts with frequent fogs and 
rains. 
B. vittatus Fldr. (170 e) is denominated owing to the conspicuous whitish-yellow straight basal ray vittatus. 
on the hindwing beneath extending through the cell almost to the distal margin. Above the disc of the fore wing 
and the whole hindwing, except the margins, are of a silky lustrous yellowish greyish-blue. The specimens 
figured all originate from Nuwara Eliga in Ceylon, from an altitude of about 7 to 8000 ft., where the species 
is not rare; other habitats are apparently not known. The $$ are without the greyish-blue coating above, 
except a faint hue, and the yellow ray of the hindwing beneath is much finer. 
B. plumbeola Fldr. (170 e) is only half the size of vittatus, otherwise similar above, in the forewing plumbeola. 
the basal half (rf) or one third ($) is silvery grey, the under surface dusty grey with a brownish tint and lighter 
small longitudinal spots and rays. Philippines. 
B. subditus Mr. is above brown with 2 pair of small lighter spots. Hindwing beneath ochreous- subditus. 
brown with a whitish longitudinal stripe from the base through the cell and another one along the hind-margin; 
smaller than the similar following species, with a contrasting light marking of the hindwing beneath. Expanse 
of wings: 27 mm. Nilghiri Hills. 
B. septentrionum W -Mas. & Nic. is very similar to subditus , larger, the light markings of the hindwing septenlrio- 
beneath scarcely lighter than the ground-colour. Expanse of wings: 32 mm. Sikkim, Shan Mts. num 
B. hampsoni Elw. & Edw. (170 e) is beneath almost exactly like vittatus (170 e), but above deep hampsoni.

34. Genus : Ochus Nic. 
Only slightly separated in the subcostal branches from Baracus of which it represents a transition to 
Ampittia. But 1 small species is known from Sikkim and Assam; Frithstorfer discovered a local race near 
Chiemhoa in August and September. The species in the habitus and colouring exhibits a remarkable resemblance, 
particularly beneath, to the South-American Hesperid Gallimormus gracilis (Vol. V, pi. 189 i), which is difficult 
to explain. 
0. subvittatus Mr. (= subradiatus Mr.) (170 f), from India, mostly from Sikkim in the collections, subvit talus.

and its small size. — intricatus Fruhst. (171 c), from Tonkin, differs from it in its larger size and larger yellow intricatus.
