Antciiiiae of S simple, laiueliiitc ; ])al])i ]ioiTect, weak, reacliiuj,' in front of 

 faee, hairy beneath, the third segment narrower, distinct ; tongue and frenulum 

 ])resent ; legs broken. 



Neuration : forewing, cell fnliy half iis long as wing; discoceliular fiiintfy 

 inbent above middle; first median nervule at five-eighths, second at seven-eighths; 

 lower radial from bend in discoceliular, and tlierefore above middle, upper from 

 upper angle of cell; T, 8, 0, Hi stalked from two-thirds, II free: hindwing, 

 costal apjiroximated to subcostal for one-third of cell ; veins 3 and 7 l)ef()re 

 angles of cell ; no radial. 



In the forewing the submedian vein is bent downwai'ds near liase, and elbowed 

 njnvards at one-fifth, emitting a short spur basewards from the elbow, but not 

 I'orming a fovea. 



Type : Neohapta indecora spec. nov. 



The type species may be allied to Cabira ocliroparpuraria H. S. ; but the 

 antennae are simple and the nenration somewhat anomalous. 



197. Neobapta indecora spec. nov. 



Forewing : dull greenish grey, thickly covered with transverse purplish 

 fuscous striae, with traces of two lines ; the first curved, at about one-third, 

 indistinct, starting from a dark costal spot ; the second submarginal, irregularly 

 waved and thickened ; a distinct blackish cell-spot ; fringe (worn) concolorous. 



lliudwing : rather darker, greyer; cell-spot and outer line only visible. 



Underside paler, without markings. 



Head, thorax, and abdomen concolorous. 



Expanse of wings : 3iJ mm. 



1 S from Rio Demerara. 



Subfamily PALYA DINAR 

 108. Argyrotome ferruginea ali. albinata nov. 



Differs from typical ferrm/ini'a Warr. in the absence of the grey scaling in 

 both wings, that colour being replaced by pure creamy white. 



Underside, thorax, and abdomen all alike creamy white. 



I ? from Salampioni, Bolivia, 80(1 m., August 19i.)I, dry season (Simons) ; sent 

 with two others, from the same locality and with the same date, of the ordinary 

 grey type. 



Gyostega gen. nov. 



Foivtri/iff : triangular ; costa slightly incurved before middle, convex at 

 ajiex ; hindmargin obliiiue, scarcely curved ; inner margin broadly lobed belbre 

 middle ; median vein fringed with hair near base above. 



IliiKliciin/ : ample ; aual angle slightly produced, rectangular ; apical angle 

 rounded ; hindmargin carved above middle, straiglit below ; inner margin lobed 

 on basal half; a large wisp of hairs from base of submedian fold, nearly reaching 

 middle of wing, covering a distorted furrowed sjiace between veins 1 and ~', 

 which forms a bulge on the under surface. 



Antennae (c?) filiform, shortly pubescent; frenulum long; tongue present; 

 jialpi porrect, short and stout. 



Neuration: forewing, cell half the length of wing; discoceliular straight, 

 oblii^ue ; first median nervule at two-thirds, second at eight-ninths ; radials
