Hyalospila gen. nov. 



Forewings elongate: costa straight, evenly curveil in the apical third; a])ex 

 rounded, blunt; hindmargin oblique and slightly curved; anal angle distinel. 

 Hindwings elongate with hindmargin rounded. Antennae of cj strongly pectinate ; 

 jialpi poiTect, slender, upcurxed ; tongue present ; hind tibiae with four spurs ; wings 

 hyaline, very thinh' scaled, almost transparent ; forewings with the foveal bar very 

 faint. Neuration : forewings, cell two-thirds as long as wing, constricted towards the 

 end ; first median at five-eighths, second at seven-eighths, third from lower end of 

 cell; first and second concave upwards, third concave downwards ; lower radial from 

 centre of discocellular ; u[iper from top end of cell, both concave downwards; last 

 three subcostals on a common stem from the last bend of the subcostal ner\-ure ; first 

 subcostal anastomosing with costal, then with second subcostal, and finally with the 

 third. Hindwings with costal and subcostal approximated for nearlv half of cell ; 

 first subcostal and second median nervule from before end of cell. 



Type : //. hynhjrin IT. S. 



Hyalospila distans sp. nov. 



Near to H. hyallnaria H. S., but smaller; the second crossbaud of the fore- 

 wings nearer the first, starting from the costa at two-thirds, and reaching the inner 

 margin also at two-thii'ds, less eiu-ved outwards and not touching the hindmarginal 

 border aliove the anal angle ; costa of hindwings more broadlv blackish. 



Expanse of wings : 44 mm. 



One t? from Santos. 



PenthopMebia gen. nov. 



Forewings elongate; costa straight for two-thirds, then curved; a|)ex blunt; 

 hindmargin obliquely ciu-ved. Hindwings with hindmargin rounded. Antennae 

 of (S pectinated; palpi short, slender; tongue present ; hind tibiae with ? four spurs. 

 Neuration : forewings, cell half the length of wing ; first median at two-thirds, 

 second ju>t before end, third from end of cell ; lower radial from centre of di.s- 

 cocellular, which is straight and nearly vertical ; upper radial from the common 

 stem of the last three subco.stals, which starts from end of cell; first subcostal 

 nen'ule anastomosing first with costal, then with .second .subcostal, and ? again with 

 third. Hindsvings with costal shortly approximated to subcostal ; two subcostal 

 nerv.ules on a common stem ; medians as in forewings. Forewings with the foveal 

 bar well marked. 



Type : Peuthopldi'hid rad'cata P'eld. ('f Genusaa). 



Stibaractis gen. nov. 



Forewings with costa gradually curved, apex blunt, but squared ; hindmargin 

 vertical in the apical half, then curved ; anal angle distinct. Hindwings with 

 rounded hindmargin. Antennae (?) subserrate, with short bristles; tongue present; 

 palpi short, thin, porrect. Neuration as in Hyalospila, in the main, but the cell 

 not so long; the discocellular curved and much more oblique; the second median 

 and common stem of last three subcostals rise much nearer the end of cell, especially 

 the latter; all the veins are thicker and stouter, and thickly marked in black. 



Type : Stibaractis dioptis Feld. (Genussa).
