(tenus Syrtodes (nion., I'h'il. ii. p. 451. 



Guene'e, when introdncing the genns Si/rtodes, divided it into thri-e groujis, 

 the first of which, containing his species et/thei-pata only, he sng^'ested wonid 

 ultimately have to form a separate genns. The species mnst either be rare or 

 overlooked ; it is not represented in the British Museum collection, nor, as far 

 as I know, is there a specimen in the Tring Museum. A single S in jierfect 

 condition from Mons. Dognin's collection, which I have lately examined, j)roves 

 that Gueuee was right. As the sjiecies inclnded in his second and third groups 

 all belong to the genns Ischnopferis of Hiibiier, his own name Syrtof/es may be 

 retained for the first species thereunder mentioned ; but his description, made in 

 the main from the insects of the other groups, reijnires rewriting. 



Fonirinq : elongate : costa nearly straight, slightly cnrved at base and apex ; 

 ajiex rectangular ; hindmargin cnrved below, smooth, not crenulate. 



llinclwinq : narrow, with hindmargin curved, and both angles rounded. 



Forehead protuberant ; palpi quite short, not reaching beyond face, rough- 

 haired beneath, the third segment hidden; antennae thick, lamellate; tongue and 

 frenulum present ; abdomen with very small dorsal tufts ; hindtibiae not thickened, 

 with four spurs ; legs long and slender. 



Forewing with fovea covered by broad scales. 



Neuration : forewing, cell more than half the length of wing ; discocellular 

 vertical, very weak ; first median nervule at two-thirds, second well before third ; 

 lower radial stalked with upper from top end of cell ; 10, 7, 8, 9, stalked from 

 two-thirds; 11 free, but approximated to 12; hindwing, costal and subcostal 

 approximated for half of cell ; 7 well before end ; no radial. 



The uncrenulated hindmargin of wings, protuberant forehead, and the fovea 

 of forewing will separate it at once from Ischnopteris, while the abnormal 

 stalking of veins .5 and (i of forewing distinguishes it from all other geuera of 

 the subfamily. 



266. Thysanopyga fulvifascia spec. nov. 



Forewing : tawny grey, thickly striated with fuscous ; lines indistinct ; one 

 near base wavy ; a stibmarginal shade j)arallel to hindmargin formed of aggre- 

 gated striations, preceded by a broad tawny band, which is distinct only above 

 the middle ; a dark blotch in end of cell ; a tawny blotch at apex ; fringe 

 fuscous, with a pale basal line beyond a blackish marginal line ; traces of a 

 minute pale cell-spot. 



Ilinrhriiiij : wholly tawny, striated thickly in basal and marginal areas ; 

 th(' broad tawny band complete ; cell-spot small, whitish. 



Underside cream-white ; both wings with broad dark fuscous border. 



Head and shoulders brownish grey : patagia apparently pale grey ; abdomen 

 wanting ; antennae black, with basal joint and shaft wliitisli. 



Expanse of wings : 28 mm.
