veins 6, 7 are stalked ; the discocellular has a long ohlicjue lower arm, and the 

 radial (vein 5) is stalked with 4 from the lower end of ceil, vein 3 rising mnch 

 nearer base, veins 1 and 2 being left in the anal lobe ; the neuratioQ is the same, 

 as far as can be seen, in the second section ; but in the third vein 3 rises closer to 

 the stalk of 4, 3, and vein 2 some distance before, vein 1 alone passing into the 

 anal lobe. In all alike the cell is broad at extremity and veins 0, 7 cnrved 

 downwards and divergent. In the hairior forms, such as harhnta, the abdomen 

 beneath is tufted with hairs. 



Type : Prosthetopteri/x caesiata spec. nov. 



In Tri ptcridia Warr., which also has the hiudwing divided into three lobes, 

 the forewing too has a deep cleft in hindmargin. 



151. Prosthetopteryx barbata spec. nov. 



Forcirimj : dull green ; the markings dark green : viz. the basal patch with 

 its edge obli(|ue outwards ; the central fascia broad, oblique outwards to middle, 

 then inwards, its inner edge approaching basal patch on inner margin; the pale 

 green space between them with dark green centre, broad at costa and narrowing to 

 a ])oint at inner margin, angled outwards in cell like the fiiscia itself ; beyond the 

 pale green band edging the fascia externally is a dark fascia with a rufous tinge 

 before the indistinct pale submarginal line ; fringe probably green. 



Ilindwing : deeply three-Iobed ; all the lobes dingy grey and fringed with 

 long curled hairs ; the middle lobe pointed and darker grey, with a curled wisp of 

 ochreons grey hairs on its inuer edge. 



Underside of forewing pale greenish, with the dark markings showing through : 

 hindwing with the middle and inner lobe thickly covered as well as fringed with 

 long fine woolly hair ; a wisp of black hairs at the end of the short npper cleft. 



Head, thorax, and abdomen greenish. 



Expanse of wings : 28 mm. 



1 c?. 



The apex of forewing is acute. 



152. Prosthetopteryx caesiata spec. nov. 



Foretving : deep brown-black, with a slight reddish tinge ; the lines blackish, 

 indistinct, except in certain lights ; a curved line near base ; another, double, at 

 about one-third ; an outer line, also double, and dentate outwards ; a dentate 

 submarginal line ; fringe dark brown. 



Ilindwing : bluish slate-colour, the fringe included ; the inner lobe with its 

 fringe shining white. 



Underside of forewing dull brown overlaid with dull bluish slate; the lines 

 darker in costal half; fringe brown with paler mottlings ; hiudwing slaty blue, 

 with dark cloudy cell-spot and cnrved outer line ; the anal lobe white as above ; 

 median vein with a pencil of purple hairs. 



Head, tliorax, and abdomen like wings ; anal tuft blackish ; underside of 

 abdomen, legs, and pectus whitish ; dorsal tufts erect, long, bluish black. 



Expanse of wings : 22 mm. 



2 SS. 



The hindmargin of hindwiugs is curved from costa to end of vein 5, where it is 

 bluntly angled, and again incurved to base of anal lobe ; in one example the angle 

 is much more prominent than in the other.
