broadened towards apex of wing ; transverse 



band white, discal rather than subbasal .... L. curius, p. G.

3 Vpperside dull brownish black. Fore wing : a broad 

 outwardly oblique white transverse band that crosses from a little 

 beyond the basal third of the costal margin to the dorsum, its 

 outer half hvaline, followed by a hyaline triangular area that does 

 not reach the costa or the termen but is traversed by conspicuously 

 black veins. Between the semihyaline transverse band and the 

 hyaline area the black forms a more or less even band slightly 

 narrower in the middle ; the black edging to the costa and termen 

 broad, broadened towards the apex ; cilia black. Hind wing : the 

 Transverse white band of the fore wing is continued straight across 

 and ends in a point on the outer half of vein 3, but is not hyaline 

 along its outer margin ; posterior half of the wing dull dark brown, 

 irrorated towards the base of the long narrow tail at vein 4 with 

 \\ hite scales ; cilia black, white below vein 5 and along outer side 

 of basal half of tail, the latter tipped white. Underside similar, 

 but the ground-colour opaque brownish black ; a broad outwardly 

 ill-defined earthy-grey streak along the base of the wings produced 

 slightly down the dorsal margin of hind and along the costa of the 

 fore wing ; the oblique white band on the hind wing joined by a 

 cross sinuous short white line from the dorsal margin to its apex ; 

 below this latter a number of irregular white spots on the torual 

 area. Antennae, head and thorax black, abdomen dark brownish 

 black ; beneath, the palpi, thorax and abdomen greyish ; claws of the 

 tarsi bifid. Male with sex-mark. 

 Exp. d 1 ? 42-52 mm. (1 -68-2-0").

cf $ . Very closely resembles L. curius, but differs constantly 

 as follows : Transverse band across fore wing placed further in 

 towards the base ; this band on both fore and hind wing greenish, 

 not white, and not as in curius with its outer margin hyaline on 

 the fore wing; black terminal edging to fore wing narrower, of 

 even width throughout. Male without sex-mark.
