326 stui)if;s in Australian nkuroptera, iv., 



proHle (probably cylindrical and of moderate breadth in life); 

 two, short, subconical, anal appendages present. (Sex indeter- 

 minate). Wings subhyaline, clouded with pale brown. Veins 

 and hairs mostly brown, but a ver)^ delicate effect of silvery-grey 

 patches is produced in forewing by the areas on either side of 

 the gradate series, and a few smaller patches along M and the 

 margins, possessing a whitish venation with whitish hairs upon 

 it; this effect is heightened by patches of dark brown along the 

 gradate series, on the pterostigma, and irregularl}- round the 

 wing-margins. The hairs of the fringe are chiefly pale brownish 

 or brownish-grey, but there are a number of conspicuous patches 

 of dark brown hairs, especially along the posterioi* margin, in 

 both wings. Cross-veiiis in forewing : five in the gradate series 

 from M.T up to R; three between R and Rs (inclusive of the 

 uppermost one of the gradate series); one below Rs just proximad 

 from the gradate series; one from base of R,s to M; one between 

 Mj and Mj, and a second just below it; also an oblique one sup- 

 porting the wide forking of Mo: one between Cu, and Cu._, and 

 one between lA and 2 A not far from base. Cross-veins in hind- 

 wing : one between Sc and R above middle of wing; one only, 

 distad from this, between H and Rs, and two exactly below this, 

 one above and one below Mj ; an oblique one supporting the 

 forking of M._,: one connecting mf to Rs; and one from base of 

 M to Cu. 



Type in Coll. Tillyard. Unique. Taken at light by Mr. O. 

 Lower, at Broken Hill, N.S.AV. Undated. 



Genus Stenobiella, n.g. (Plate xix., fig.35). 



C/haracters as given in the generic key, with the following 

 additions. Size rather small (expanse about three-quarters of 

 an inch): antennje about two-thirds the length of the forewing: 

 three branches to Rs in both wings. In hindwing, Cu, comes 

 very close to posterior margin at the level of the ending of lA, 

 and thence onward, for about one-third of the wing-length, runs 

 parallel to, and just above, the wing-margin, giving off a number 

 of exceedingly short, unbranched veinlets to it: Cuj is connected 

 with 1 A bva cross-vein. Costal cross-veins in forewing branched
