( 133 ) 



Forewings with costa curved; apex slightly produced; hindmargin faintly 

 sinuons; hindwings triangular with inncrmargin very long; hindmargin nearly 

 straight till towards anal angle, then curved; scaling fine; the scales pale with 

 dark tips, arranged so that they form numerous pale and dark green transverse 

 wrinkled lines. 



Dnicia gen. nov. 



Forewings: with costa slightly curved; apex produced; hindmargin oblique, 

 hardly curved, slightly indented above anal angle which is well-marked. 



Hindwings : with ajiex rounded and anal angle rectangular; a decided tooth 

 at vein 4, the hindmargin sinuate above, straight below to anal angle. 



Antennae pectinated in both sexes; palpi porrect, the terminal joint slender, 

 much longer in ? than in i; tongue and frenulum present; abdomen with tufts of 

 red scales. 



Neuration : forewings, cell half as long as wing ; discocellnlar vertical above, 

 strongly concave below; first median at two-thirds, second close to third; lower 

 radial from the bend in discocellnlar, upper from top angle of cell; veins 10, 7, 8, 9, 

 stalked from the angle; 11 free, osculating or anastomosing with 12; hindwings, 

 discocellnlar with lower half oblique; veins 0, 7, and 3, 4 stalked. 



Type : Drucia delpkinata sp. nov. 



Rackeospila asmura Druce also belongs here. 



The genus agrees both in structure and shape of wings with Progonodes Warr., 

 but the scaling and markings are quite dissimilar. 



40. Drucia delphinata sp. nov. 



Forewings : green ; the costa pale ochreous with brown freckles ; cell-spot 

 black; a horseshoe-shaped mark on hindmargin from apex to vein 4, cream-colonr 

 washed with flesh pink, edged with red-brown, with red-brown specks in it, and with 

 a faint shade across middle; a similar smaller blotch before anal angle, narrowed to 

 hindmargin ; marginal line red-brown, darker brown and forming triangles beyond 

 the subapical blotch; fringe cream-colour chequered with pink. 



Hindwings : with a large oblong blotch at apex reaching to the tooth at 

 middle; a square blotch at anal angle, narrowing above at middle of inner margin, 

 then swelling into a semi-oval shape to near base; no cell-spot. 



Underside pale sea-green, with the blotches showing dull white. Head, palpi, 

 and antennae dull red; thorax green; abdomen ochreous, with reddish dorsal crests. 



Expanse of wings : 28 mm. 



One c? from Sao Paulo. Allied to D. asmura Druce {Rackeospila) from 

 Panama. 



41. Gelasma hemithearia sp. nov. 



Forewings : dull grey-green, or olive-green ; the lines slightly paler, the teeth 

 marked by whitish points on the veins ; first from one-fourth of costa to one-third 

 of inner margin, angled outwards in cell and on submedian fold, followed by a 

 deeper green tinge ; the second from three-fourtiis of costa to three-fourths of inner 

 margin, incurved beyond cell and on submedian fold, projecting on veins 3 and 4, 

 preceded by deeper green ; costa ochraceous, with purplish speckles ; cell-spot
