Genera and Species o/'Pyralidse. 435 



Roeseliodes, gen. nov. 



Fore wings narrow, elongate ; costa straight ; hind margin 

 obliquely curved; apex blunt; labial palpi (female) erect, 

 the second joint with long erect hairs, partially hiding the 

 terminal joint, which is aciculate and rises above the vertex ; 

 tongue and ocelli present ; maxillary palpi invisible ; antenna? 

 in female annulatecl, filiform, in male coarsely pectinated, 

 enlarged at the base, which also bears a dense erect tuft j 

 near the base of the submedian between it and the interno- 

 median is a bladdery protuberance, and the underside of the 

 fore wing is beset with hairs ; cell long, the end wedge- 

 shaped ; first median nervule from the angle at the base of 

 the wedge ; second, third, and lower radial from the point ; 

 between the median and submedian is a strongly developed 

 independent surplus vein, which near the base stands out as 

 prominently as a true vein, as in Castnia ; this vein reappears 

 in the hind wing. 



Type R. ochreosticta. 



Roeseliodes ochreosticta, sp. n. 



Fore wing whitish grey, dusted and suffused with darker 

 grey, especially throughout the basal and apical areas ; first 

 line very indistinct, blackish, running obliquely outward from 

 the costa to middle of wing and then vanishing ; the dull 

 dark grey basal area contains a small bright yellow patch of 

 scales shortly before its outer margin in the middle ; second 

 line denticulated, but only indicated by the darker points upon 

 the veins ; central area paler, containing an oblique dark 

 dash over the discocellular; the second line is immediately 

 followed by a similar pale line ; submarginal area dark grey, 

 showing a row of blackish dashes before the fringes, which 

 are pale, with darker base. Hind wings dull whitish, with 

 the veins and border fuscous. Head, thorax, and abdomen 

 dark grey.

 half ochreous or bone- colour, with the costa and veins dark 

 brown ; a linear black dash in the middle is conspicuous ;
