( -252 ) 



lirowii-black lilotch, sLar])ly dofiiied by vein 6 ; marginal area greyish ochreons, 

 sejiarated from outer line by a pale line, iuterrnpted by the ochreons veins ; a small 

 dark costal spot before apex ; marginal line dark, waved ; fringe grey, with a white 

 base ; cell-spot dark, distinct. 



Ilindwings : with a black dash at base ; an ochreons antemedian lino, forming 

 a sinns between median and subcostal veins, containing a large round blackish cell- 

 spot ; outer line straight, slender, and double ; the rest as in forewings. 



Underside white, thickly peppered with brown ; the lines brown ; a broad sub- 

 marginal brown fascia, extending to hindmargin abt)ve the middle, followed by a 

 white blotch below the middle of both wings and at ajiex of forewings, these white 

 blotches forming faintly paler spaces in the dark marginal area of the upperside. 

 Head, thorax, and abdomen ochreons, mixed with grey. 



Expanse of wings : 30 mm. 



One ? from Bali, March and Ajjril 1896 ("\V. Uoherty). 



Like G. niptifasciata Warr. from the Khasias, but smaller ; the outer dark 

 fascia reduced to a single blotch on costa of forewings.

The type originally described was a $ from Dili, Timor; the ? , of which 1 have 

 now seen an example from Pringabaja, Lombok, cajrtured April 189(), by Frulistorfer, 

 ditfers mainly in the fuscous speckling being more mixed with ochreons scales: the 

 inner dark line is nearer the base; an ochreons cnrved median line touches the black 

 cell-spot, and the postmedian fascia is edged internally by an interrupted black 

 line ; the face and palpi are ochreons fnscous, rather than ferruginons. The slight 

 differences here noted may be really sexual, or, as is ei^ually i)robable, may represent 

 slightly variant local forms. 



Hyostomodes gen. nov. 



Forewim/s : with costa straight lor two-thirds, then decidedly convex ; apex 

 somewhat produced, bluntly rounded ; hindmargin oblique, very faintly indented 

 opposite the cell: fovea absent. 



Hindirings: with hindmargin rounded, slightly toothed at middle and suli- 

 crennlate aliove. 



Antennae of S pubescent, of ? simple; palpi porrect, laxly scaled; tongue and 

 frenulum ])resent ; forehead with a bilobeJ chitinous projection, enclosing a longer 

 prominence, distinct in S, but obscure in ?. 



Type : Hyostomodes nubilata sp. nov. 



A development of Tephrina Dup., with which it agrees in nenration. 



159. Hyostomodes nubilata sp. nov. (PI. V. tig. 11, S). 



i. Forewings: whitish, thickly dusted and striated witli dark grey; costa 

 darker; lines starting from dark costal spots; first and median obscure, at one-fourth 

 and one-half; outer line at three-fourths, starting olili(iuely from a dark costal triangle, 

 angled acutely on vein 6, then irregularly cnrved to inner margin at two-thirds ; 

 edged on costa with i)alo, and followed by another dark blotch ; marginal area 

 snCfused with smoky grey, darker beyond cell and at anal angle, and in places along 

 the outer line ; an obscure jiale olilii|ne blotch from apex; marginal line dill'usely 

 dark grey; fringe grey, with a pale basal line.
