with a fringe of long bristly hairs above ; hind tarsus smooth, 

 normal. Metathorax relatively large, as in Opogona. 



Fore wing (Plate V, figure 1) lanceolate, not caudate, but 

 distinctly curved down at the apex; cell narrow, with a broken 

 dividing vein from base to apex, weakly connected with the 

 front edge of the cell halfway between the origins of 7^1 ( 11 ) 

 and R2 (10), probably representing part of the base of media 

 and the stem of R4+5; Rl arising at one-third length of cell, 

 R2 just beyond middle, the stem of R between them definitely 

 angled at the point of separation of 7^4+5; R3 (9) arising 

 shortly before end of cell, well separated from R4-M2 (5 to 8), 

 which arise from a common stem at end of cell; 7? 4 (8) given 

 off before .172 (5), and Ml (6) practically obsolete, but I tli ink- 

 traceable ; R5 (7) running to costa; free parts of dorsal veins 

 parallel, but .1/3 (4) strongly converging at origin to the stem 

 of R4-M2; .1/3 and Cnl (3) separated by a moderately long 

 bent vein, which receives the dividing vein of the cell, Cnl and 2 

 (3 and 2) by a long oblique vein; 1st A (Ic) free, the outer 

 part well chitinized ; 2nd A (Ib) distinctly forked at base. 

 Hind wing two-thirds as wide, lanceolate, with the costa hardly 

 at all concave at the middle; fringe 2; 5V (8) ending at two- 

 thirds, running close to costal edge; R (7) moderately sep- 

 arated from .171 (6), running obliquely to costa; Ml (6) to 

 apex; .172 (5) nearly connate with it, continuing the distinct 

 base of .17; cell open below M2\ .1/3 (4) lost; Cnl (3) and 2 

 (2) forming a strongly forked free vein; 1st A (Ic) well de- 

 veloped; 2nd A (Ib) short and obscurely forked; 3rd A (la) 

 practically obsolete. Frenulum simple in both sexes ; frenulum- 

 hook of male normal, of female made up of a series of hooked 

 hair-scales, apparently without any membranous portion. 



Fixed hairs are completely absent, except for the usual patch 

 on the inner margin of the fore wing, even the small area over 

 the base of 7?, which exists in Opogona and Opostcga, being 

 lost, and represented only by a group of weak transverse folds. 

 The female ovipositor is membranous, slender and extensile. 



The genus will run by Meyrick's key ( I 'roc. Linn. Soc. N. S. 

 W. 22: 298, 1897) to Losostoma (Opogona), from which it 

 differs in many particulars, especially the convex front, and
