incurved and parallel to the subcostal towards the base ; 

 subcostal forked, the branches upon a rather long foot- 

 stalk ; radial emitted near to the median, which is two- 

 branched, and replaces both submedian and internal, 

 which consequently are absent ; palpi short ; antennse 

 filiform, thicker in the male than in the female ; body 

 slender, scarcely extending beyond the secondaries. 



86. Ha'plopteryx anomala, n. s. 



Primaries dark shining grey, sprinkled with black and 

 white scales, and with a slender transverse white dash at 

 the end of the cell ; upon the central band, which is 

 whitish or buff in the female, but of the ground colour 

 in the male ; this band is very irregular, is much con- 

 stricted in the middle, and is bounded on both sides by 

 about five very irregular undulated and angulated more 

 or less defined black lines, which occupy the central 

 three-fifths of the wing-surface ; beyond the cell these 

 lines are zigzag, much as in Scotosia certata : two sub- 

 basal straight approximated black lines ; a triangular 

 costal apical patch of grey or buff ; an internally blackish 

 bordered regularly zigzag white submarginal line ; ex- 

 ternal border dark, sometimes brown ; a marginal series 

 of black spots in pairs, sometimes united into a con- 

 tinuous line ; fringe shining grey, traversed by a blackish 

 stripe, and with a slender white basal line ; secondaries 

 whity brown or dark smoky grey, with a slender dusky 

 marginal line ; fringe traversed by a dusky stripe ; body 

 greyish or whity brown ; under surface shining grey, 

 more or less tinted with bronze-brown ; secondaries of 

 male whitish ; an abbreviated dusky zigzag streak beyond 

 the cell of primaries ; the male also with the external 

 border pale buff, with regularly zigzag inner edge. Ex- 

 panse of wings, (? 41 mm. ; 2 38 — 42 mm.

Allied to Tatosoma of New Zealand ; general aspect 

 (excepting in the form and size of its posterior wings) of 

 Tomopteryx fissa of Felder ; primaries very broad and
