LEUCANIA. 51 



LEUCANIA, Iliiljii. 



Lencania percisa. (Plate CXXVI. figs. 10, 11.) 

 Leucania percisa, ^oore, Proc. Zuot. tioc. 1888, p. 410. 



Near to L. straminea of Eui'ope and still nearer to L. venalba of India. It differs from 

 the latter in its slightly longer primaries, the costal border of wlueh is of the clear sericeous 

 wliity -brown tint of the subraedian 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, l)ut 

 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.

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-album, penicillata, and bistrigata. 



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 gi-eyish. Wings below silvery 

 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 l)ifasciata. (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
