Genotype, D. (lihhosn, n.sp. 



Apart t'l'om tlie })eculiar shape of the wings, the venation 

 shows this genus to be closely allied to Megalunilua Banks, with 

 which it agrees in the number and form of the gradate veins, 

 there being three in the forewing and two in the hindwing, 

 though the middle series of the forewing and the inner of the 

 hindwing are more complete than in Mcgcdomina. 



8. Drepanomina gikbosa, n.sp. (Plate xiv., fig. IS). 



TafdJ h'nijfh 7 mm., J'(»r/rini/ 10 mm., expanse 21 "5 mm. 



Head brown, heavily marked with shining black on epi- 

 cranium and face; eyes dark brown; antenncH pale brow n at base, 

 the rest ochreous, annulated with dark brown. T h o r a x : pra-

 nately speckled with dull whitish and dark brown, the general 

 eftect being a medium brown colour all over the wing; posterior 

 margin fi'om apex nearly to base marked with dark brown in 

 regular patches, isolating paler areas suggestive of the lunules of 

 Drepanacra\ a darker brown cloud runs obliquely aci'oss the Aving 

 not far from the falcate border, and is widest on the posterior 

 margin, and tapering almost to a point towards the costa, not 

 far from the apex; a number of short, dark, oblique streaks on 

 R, and just proximally to the brown cloud. Hindivlngs with 

 venation around the margins, and in distal half of wing, dull 

 brown; in basal half of wing, whitish; pterostigma pale straw- 

 colour. No fenestella. 



Radial formula 2-f-l-fl+l+l=6. Hindwing with tiAe 

 branches to lis; only one false origin, but that very strongly 

 developed, Rs being strongly looped concavely to R, and strongly 

 bent at origin (jf its most basal branch. 



Type in Coll. Froggatt. Unique. Not labelled; but Mr. 

 Froitiratt informs me that it was taken in V^ictoria.
