TORTRICINA. 281 



tufted, and trigonate behind. Anterior wings elongate : length more 

 than twice the width. Costa nearly straight, slightly arcuated at 

 the base, and concave in the middle ; apex arcuated, obtuse ; apical 

 margin oblique, rounded ; dorsal margin rounded. The costal vein 

 attains the margin at the middle ; the discoidal cell lies in the upper 

 half of the wing, extends scarcely two -thirds its length, spacious, 

 and widest before its apex. The subcostal nervures not equidistant ; 

 the first inserted two-thirds from the base, preceded by an internal 

 spur on the subcostal vein. The submedian nervure inserted towards 

 the apex of the discoidal cell. Posterior wings ample ; apex obtuse ; 

 apical margin very concave ; dorsal margin entire ; costal margin 

 very concave. Abdomen slender in the J , stout in the $ ; apex 

 tufted in both sexes. 



A singular genus, and presenting remarkable peculiarities in 

 structure, colours, and clothing. In the clothing of the anterior 

 wings there is some resemblance to Oxygrapha and Peronea, 

 but the long antennae, the acutely-truncated apex, and the ex- 

 treme length of the palpi, besides the abnormal shape of the 

 middle joint, at once remove it from all proximity to those genera. 

 The larva has not been sufficiently observed to offer characters 

 for classification.

Head white, a few brown scales over the eyes. Face white. Eyes 

 black. Palpi more than twice the length of the head ; above, be- 

 tween, and at the sides white, with a few brown scales on the latter, 

 beneath slightly drab. Antennae pale brown; basal joint clothed 

 with white scales. Thorax : on the vertex white, edged at the sides 

 with black ; the crest or tuft white, with rich orange scales at each 

 side. Patagia rich drab, speckled with chestnut-brown at the base, 

 pale at the apex. Anterior wings dull, white ground-colour, thickly 

 marked with obovate or reniform patches of various colours, with 

 numerous tufts of elevated scales, which are white when viewed ob- 

 liquely from the base, and black when viewed towards the apex: 

 vertically these tufts are scarcely perceptible, and are of different 

 colours, according to the colour of the markings on which they are 

 placed. At the base is a streaky patch, extending one-fifth along the 

 costa, of dull drab or pale fuscous colour, streaked with umber, and 

 paler on the dorsal margin. In the middle of the costa is a truncate 

 triangular, fuscous patch, speckled and edged anteriorly with umber ; 

 at the truncation is a small roundish, fawn-coloured ocellus, with a 

 minute dusky centre, and bordered with white : meeting this from 

 each side of the triangular patch, are two broadish bands, the ante- 

 rior of a rose pink colour (which soon fades after death), the posterior
