LEUCANIA, Hdbn. 
Leucania percisa. (Plate CXXVI. figs. 10, 11.) 
Leucania percisa, Moore, Proc. Zool. Soc. 1888, p. 410. 
Near to L. straminea of Europe and still nearer to L. venalba of India. It differs from 
the latter in its slightly longer primaries, the costal border of which is of the clear sericeous 
whity -brown tint of the submedian area, instead of being greyish as in L. venalba ; in the 
more ivory-white median vein with its third branch and the much darker shade enclosing 
them : the secondaries more or less clouded with grey, especially at the outer margin, but 
usually without the black marginal dots of L. venalba ; the fringe in dark males traversed by 
a dusky stripe. Expanse of wings 36-38 millim. 
(J 9 , Dharmsala ; at sugar in J uly. 
It seems a little doubtful whether this is really a distinct species from L. venalba ; but 
as Mr. Hocking only obtained one example of the latter, the question must at present remain 
unsettled ; a longer series might render the separation of the two forms impossible, as in the 
case of L. l-albuin, penicillata, and bistngata. 
Leucania irrorata. (Plate CXXVI. fig. 12.) 
Leucania irrorata, Moore, Proc. Zool. Soc. 1888, p. 409. 
Primaries sericeous whity brown, irrorated with fine black scales ; a short longitudinal 
blackish basal line below the median vein, a black spot at the end of the cell followed by two 
or three small irregular blackish markings ; the end of median vein and commencement of 
its third branch white ; a marginal series of black dots : secondaries sericeous silvery grey 
with faint golden reflections; veins and margin dusky ; fringe yellowish at base, traversed by 
a grey stripe and tipped with silvery white : thorax whity brown; palpi blackish at the sides ; 
collar traversed by three squamose blackish lines ; abdomen greyish. Wings below silverj'^ 
white, the primaries strongly and the secondaries slightly tinted with brassy yellow ; costal 
borders irrorated with black; a marginal series of black dots: body below whity brown^ 
slightly greyish. Expanse of wings 38 millim. 
Dharmsala. 
Leucania bifasciata. (Plate CXXVI. fig. 13.) 
Leucania bifasciata, Moore, Proc. Zool. Soc. 1888, p. 410. 
Primaries sericeous reddish clay-colour, washed with purplish lake in the discoidal cell, 
which is flanked in front and behind by a broad streak of cream-colour ; outer half of median 
vein and veins on the disc slenderly pure white, the basal half of the median vein and a 
longitudinal streak curving upwards to near apex grey ; a black dot at the inferior angle of
