apex ; tin; oulcr edge very ol)li(|uc and long, nol IkmiI, t'lilly as long as tlio 

 inner edge. Hind wings very long and narrow, regularly oval in outline, the 

 costal edge long and straight, apex rounded; the inner edge merged with 

 the outer, more so than in Carsia. Venation: two short suheostal cells, the 

 first tlirec subcostal vemdes sulx-cpial, the origin of second and third adjacent; 

 the median venules very short. Fore legs witli the til)i<i; sliort and very 

 thick, armed with a large ])rojecting spine in i)oth sexes; hind legs long and 

 slender, tarsi much longer than the tibiae. Male abdomen large, thick, long, 

 extending to an unusual distance beyond the hind wings. Coloration : jiale 

 whitisli-gray, with. three rows of black spots on the fore wings. 



This genus, remarkable for the spines on tiie tore legs, .somewhat resem- 

 bles Carsia in llu! long f()r(! wings and ovid hinder pair, but diders in the 

 venation. The head is unusually lull in front, and the palpi an; larire, while 

 the antenn;\j are not ciliated.

1 (? and 1 9. — Form of the body and wings much as in L. farinata 

 Hufn. of Europe. The wings are a little more rounded at the apex, espe- 

 cially in the female; the form of the head is the same; the palpi, however, 

 are a little longer, and the two unequal sj)ines on the fore tibiae a little shorter 

 than in the European L. farinata. Body and wings whitish-cinereous, part 

 of head and palpi dark brown. Fore wings whitish-ash, with three series of 

 conspicuous hlack, mostly vennlar, spots ; the inner row within the basal 

 tliii-d of the wing; one obscure costal spot, another .situated on the median 

 vein, a longitudinal black spot in the intenspace below and another on the 

 internal vein. Beyond the middle of the wing, an oblique line of about eight 

 longitudinal black venular spots, and just beyond a row of about eight black 

 venular dots. A submarginal, slightly sinuous, broad, while line, with an 

 apical scallop. Fringe whitish, with a blackish marginal line. Abdomen 

 and hind wings unit()rmly smoky-ash, with no markings. Beneath, l)oth 

 wings smoky -ash ; around the edges, especially of the fore wings, finely 

 dusted with white. Two or three subapical costal faint spots. Fringe white,
