pilose, laxly fringed at the sides ; middle and hind tibiae spurred. Female. Wings 

 larger, broader : forewing less triangular : hindwing more convex externally ; 

 antennee simple. 



CHEROMETTIA FERRUGINEA (Plate 132, Fig. 1, la, $ ?, \h, larva). 

 Belippa ferruginea, Moore, Annals of Nat. Hist. 1 877, p. 348. 



Male and female ferruginous, cilia purplish-cinereous : forewing washed with 

 chalybeate scales at the base, disc, and the apex ; crossed by a subbasal darker 

 sinuous band, a black- speckled spot at lower end of cell, and a large white-speckled 

 black spot at apex of wing, which also crosses the cilia : hindwing paler ferruginous, 

 with a small black-speckled spot at apex, and a short streak at anal angle. Abdomen 

 with a slight dorsal black segmental fringe. Underside paler than above, the black 

 apical spot on forewing prominent, those on hindwing less so. Tibiae with a terminal 

 black streak. 



Expanse, ^ 1|, 2 l-l inch. 



Larva limaciform, naked, oval, convex above, pale bluish-green, with several

Rahila, Walker, Catal. Lep. Het. Brit. Mus. xxxii. p. 507 (1865). 



Forewing elongate, narrow ; costa almost straight, apex pointed, exterior margin 

 oblique ; first subcostal branch emitted at one-third before end of the cell, second at 

 one-ninth, bifid at one-third from its base, fourth touching the third near its base, 

 fifth from the fourth below the point of juncture with third ; discocellular concave, 

 bent near the lower end, upper radial from end of cell in a line with subcostal, lower 

 radial from angle of discocellular ; a slender discoidal veinlet emitted, within the cell 

 from end of lower discocellular ; middle median from an angle immediately before 

 end of the cell, lower median at beyond one-third before end of the cell ; submedian 

 with a lower basal branch : hindwing short, apex convex; cell broad, extending 

 nearly half the wing ; two subcostal branches on a footstalk beyond end of the cell ; 

 discocellular recurved, radial from its middle ; a discoidal veinlet emitted within the 

 cell from middle of discocellular ; two upper medians from end of the cell, lower at 

 one-fourth before the end ; submedian and internal veins. Thorax rather broad, 

 hairy ; abdomen somewhat slender ; palpi porrect, slender, somewhat cylindrical, 

 projected beyond the head ; antennse bipectinated to tip, branches short ; legs
