length of costa ; vein 5 considerably nearer to 4 than to 6 ; vein 3 

 well before end of cell ; vein 2 almost equidistant from vein 3 and 

 base of wing. Hind wing elongate, outer margin even ; vein 7 

 well before end of cell ; discocellulars faint, vein .5 not traceable ; 

 vein 3 immediately before end of cell ; vein 2 twice as far from base 

 of wing as from end of cell ; lower margin of cell angled at vein 2. 

 Hind tibise with two pairs of spurs. Tbere is a very dense fringe 

 on the hind tibite and femora and also on the middle femora. 



Male with a linear discal stigma extending from the base of vein 

 3 to as far as vein 1.

57. Genus Unkana. 

 Unkaaa, Dist. Rhop. Mai. p. 369 (1886). Type, hatara, Dist. 

 Antennae long ; club moderate, elongated, with a long terminal 

 crook. Palpi : second joint densely scaled, third joint almost 

 concealed. Fore wing produced at apex, outer margin considerably 

 longer than inner margin ; cell of fore wing less than two-thirds the 

 length of costa ; discocellulars inwardly oblique ; vein 5 considerably 

 nearer to 4 than to 6, but not from close to bottom of cell (except 

 in elia) ; vein 3 well before end of cell ; vein 2 almost equidistant 

 from vein 3 and hase of wing. Hind wing produced in the sub- 

 costal area, outer margin even, conspicuously excised between veins 

 3 and 1 h ; vein 7 well before end of cell ; discocellulars and vein 

 5 very faint ; vein 3 well before end of cell, about twice as far from 

 2 as from 4 ; vein 2 considerably nearer to end of cell than to base 

 of wing. Hind tibise with two pairs of spurs.

It seems very douhtful if all the above are congeneric. There 

 are no sexual characters on the wings of hatura, attina, or wats(mii. 

 In the male of elia there is a short discal stigma on the upperside 

 of the fore wing extending from the base of vein 3 to just beyond 

 vein 2, and there is also a tuft of hairs on the underside of the fore 

 wing at the origin of vein 1 ; in semamoi-a there is no discal stigma 

 but there is a tnft of hairs similarly situated to that of elia. Seina- 

 mora, ivatsonii, and elia all differ slightly in neuration from batara, 

 and the two former also differ in the crook to the antenniB being 

 very short. /Vll these species, however, seem to be conveniently 

 included under Unkana for the present. 



Is batara identical with cruda, II. -S. ? 



Confined to the Oriental region.
