Polysphalia gon. nov. 



c7. Foreidng : costa rough-haired and funning a i)rae-apical lobe ; apex ronrKicd ; 

 hindmargin obliquely curved. 



llindirinij : narrow ; hindmargin indented beyond cell. 



Antennae lamellate ; palpi porrect, decumbent ; hindtibia with four spurs. 



Neuration of Chlorocb/stis, but distorted ; the cell-fold raised above and 

 furrowed below towards hindmargin, the lower radial being obscured; veins 1'2 

 with 11 and 10, running into the lobe, 9 and 8 into the costa at its end, and 7 into 

 apex ; the median vein is thickened and contorted at liase, the wing memlirane 

 beneath it partially hyaline ; the fold in cell bears a ridge of black erect scales. 



Neuration of hiudwing, and of both wings in ? , normal. 



Type : Fohjsphalia cristigcra spec. nov. 



loO. Polysphalia cristigera spec. nov. 



Fcirriciiuj : pale greyish green, with numerous waved greyish lines across it; 

 four in basal area, the fourth ])eing the inner edge of central fascia, angled on 

 median and marked by blackish dots on veins ; outer line at two-thirds, excurved 

 aliove, marked by blackish teeth inwardly on veins, preceded by two grey lines ; 

 snbnmvginal line pale, waved, the teeth filled up with dark grey, blackish below 

 costa and beyond cell ; margin between 3 and 4 slightly paler ; marginal lunules 

 black ; fringe chequered green and greenish white. In the c? the cell-fold bears 

 a ridge of black scales iu cell, and the furrow beyond is marked with rough 

 reddish scales. 



llindniiii/ : with a dark bar at base ; the rest as in forewing ; the outer line with 

 its black vein-dashes distinct and followed by a pale green band with dark centre. 



Underside grej'-green in forewing, whitish green in hindwing, with the 

 lines dark. 



Head, thorax, and abdomen green, speckled with dark ; the face and vertex 

 clearer. 



Expanse of wings : cJ 15 mm. ; ? 2ti mm. 



1 c?, 1?. 



The ? is more thickly speckled with grey. 



Prosthetopteryx gen. nov. 



Forewing: with neuration of Tcphroelg.^tin, i\w arcole large and single; the 

 structnre of wing normal. 



Hindwing: in ? normal also ; in c? subject to numerous variations of structure. 

 In the typical section, including raexiata and rfltundata, a deep cleft runs up 

 towards base below vein 3, forming a large triangular anal lobe, like an additional 

 wing ; this lobe is densely fringed, and below covered with woolly hair ; median 

 vein at base with a pencil of hairs; the wing above vein 3 rounded. In another 

 section, comprising catilinea and barbata, a second cleft, less deep, occurs below 

 vein G, so that the wing is divided into three parts, all more or less contorted and 

 hairy, the wing in one case, j)arvijien?iatii, being quite dwarfed; or again, as in 

 liridisecta, the lower cleft becomes a short rounded excision and the anal lobe is 

 quadrate and bifid. Again, in a third sectiun, latistriga, the cleft is short and 

 below vein 2, and the upperside of wing is hairy. 



In the typical section vein 8 anastomoses with subcostal to near end of cell ;
