Prasinochrysa gen. nov. 



Few/rings : with costa straight for two-thirds, then convex ; apex rectangular ; 

 hinilmargiu curved. 



Ilindwings : with apex rounded ; hindmargin curved, somewhat indented before 

 anal angle, which is square and prominent. 



Antennae of cJ subdeutate, ciliated ; palpi porrected upwards, slender, smoothly 

 scaled ; tongue and frenulum present ; hindtibiae thickened and flattened, covered 

 with a tnft of hair, hiudtarsi very short and aborted. 



Neuratmi : forewings, cell half the length of wing ; discocellular vertical ; 

 first median nervnle at tliree-fonrths, second sliortly before third ; lower radial from, 

 above the centre of discocellular, upper from top end of cell ; 7, 8, 9 stalked ; 1(J 

 from the same point, anastomosing with 11 high up and again shortly afterwards 

 with 7, 8, 9 ; 7 rising from the end of areole ; the second areole very small ; hind- 

 wings with the two subcostals from end of cell ; medians and radial as in forewings. 



Type : P. eucharis Drury (= Chri/sange detracta Wlk.). 



It seems im^wssible to locate this species iu any of the existing genera of 

 Sterrkinae. 



Prospasta gen. nov. 



A development of Ptgchopoda Stph., on the lines of ^1. amplipennis Butl. 

 from India. 



(? Forewings ; with the inner margin very short, not more than half as long as 

 the costal margin ; the hindmargin almost equalling the costal in length, distinctly 

 sinuous, bulging outwards between veins 2 and 4, the anal angle appearing lobed 

 and jirojecting over the hindwing. 



Ilindwings : of ordinary shape, the ajicx rounded, the anal angle squared ; 

 a long pencil of hairs from the base lying along the fold within the inner margin. 

 Hindtibae thickened and flattened, without spurs ; tarsi quite short. 



Antennae ciliated ; mouth parts damaged. 



Type : Prospasta data sp. nov. 



108. Prospasta elata sp. nov. 



Forewings : pale ochreous, the markings chestnut-brown ; a spot at base of cell ; 

 one on costa at one-third, representing first liite, which is slightly curved outwards 

 and runs to the middle of inner margin ; a small cell-spot ; a sinuous double outer 

 line from two-thirds of costa to inner margin close before the anal angle, wliere it is 

 most distinctly marked ; fringe apparently concolorous with ground-colour. 



Ilindwings : with a broad central chestnut fascia, commencing narrow before 

 middle of costa, bnt on inner margin extending from anal angle to one-third from 

 base ; tlic area beyond it dusted with brown. 



Underside wholly ochreous ; the pencil of hairs along inner margin of hindwings 

 brownish. Head, thorax, and abdomen ochreous ; middle segments of abdomen brown. 



Expanse of wings : 17 mm. 



One J from Paramba, Ecuador.
