LEUCANIA. 33 



with the pale parts of the wing less pronounced and the _l-shaped marking shorter : secon- 

 daries with the whole disk, excepting towards the costal and abdominal margins, smoky 

 blackish, with black marginal spots. All tbe wings below, excepting at the margin, sparkling 

 metallic silver: primaries with the usual black costal spot beyond the cell. Expanse of wings 

 36 millim. 



Darjiling [Lidderdale, fyc). 



Nearest to L. bistrigata, the Indian form of L. l-album. 



Leucania hamifera. (Plate CIX. fig. 7.)

 tJ . Leucania hamifera, Walker, Jburn. Linn. >%c. vi. p. 179 (1802). 



Both sexes alike on the upper surface and much resembling the European L. loreyi, 

 excepting that the primaries are of a pale flesh-brown tint, and that at the extremity of the 

 main stem of the median vein there is a white _l-shaped marking, as in the preceding species : 

 the secondaries also have a broad, diffused, pale brown border. On the under surface the male 

 is entirely different, being densely sprinkled from the base to beyond the middle of the wings 

 with sparkling silver scales, as in the preceding species, excepting that they cover less of the 

 wing-surface. Expanse of wings 37 millim. 

 5 , North India ; c? ? > Sarawak, Borneo. 



The true L. exsanguis of Guenee cannot be this species ; it is said to resemble the 

 Chilian L. impuncta (which L. hamifera does not), and it is distinctly stated to have no marking 

 on the wings beyond the pale veins, and here and there a few badly defined black dots, which 

 in well-marked specimens tend to form a double Hue; some little very fine black dots in front 

 of the fringe, aud at the apex an oblique pale streak. The female of L. hamifera is figured.
