Twiddle, then gradually diverging; discocellulars angled on vein 

 5, dorsal curved so as to become rather strongly oblique, costal 

 edge of cell not much shortec than dorsal. Type, Nearchci alba 

 Swin. 



Mr. L. Prout first pointed out to me that this genus belongs to 

 the Geometrince, and he is certainly correct. The strong approxi- 

 mation of vein 5 of hind wings to 6, the absence of a frenulum, 

 tosfether with the smooth face and anastomoses of vein 11 of 

 forewings are decisive. The exact place among other genera is 

 more difficult to determine. The somewhat long approximation 

 of vein 8 of hindwings to cell, as in the Monoctenimice, may be 

 ancestral, but may also be a recent modification secondary to the 

 narrowed hindwings, and in either case is nearly as well marked 

 in Euloxia gratiosata. The absence of a frenulum is not likely to 

 be found in a primitive genus. The anastomosis of 10 with 9, the 

 pectinations of antenna; to apex, the narrow wings and the white 

 coloration are peculiar characters, but not of great importance. 

 The genus is one of the peculiar forms of Australia, and does not 

 appear to have any near allies.

^2- 22-24 mm. Head, face, palpi, antennee, thorax, and abdo- 

 men white. Legs whitish. Forewings narrow, triangular, costa 

 slightly arched, apex rounded, termen strongly bowed, strongly 

 oblique; shining white; a suffused whitish-ochreous subcostal 

 streak along veins, and sometimes a narrower streak along median 

 vein; cilia white. Hindwings elongate, narrower than forewings, 

 termen very strongly rounded; shining white; cilia white.
