TORTRICINA. 191 



west ; it has likewise been taken in Norfolk, and at Shustoke in 

 Warwickshire. In Scotland it has been taken in the vicinity of 

 Edinburgh. 



Genus III. ROXANA, STEPHENS. 



Palpi longer than the head, remote, ascending ; basal joint droop- 

 ing, elongate, truncate ; apical minute, ovate, partly concealed by the 

 long scales clothing the apex of the middle joint, not so long as the 

 basal ; middle joint ascending, curved, moderately stout, thickest 

 beyond the centre, five times as long as the apical. MaxillaB longer 

 than the palpi. Anterior wings: length equals twice the width. 

 Costa regularly arcuated ; apex obtuse ; apical and dorsal margins 

 slightly rounded. The discoidal cell extends scarcely two-thirds 

 along the wing. The costal vein attains the margin about one-third 

 from the base, subcostal nervures not equidistant. Posterior wings : 

 apex obtuse ; apical margin slightly concave, dorsal margin entire. 

 Abdomen slender in the tf , stout in the $ , tufted in both sexes ; 

 the tuft small in the . 



Another aberrant genus. The only British species contained 

 in it is included by Treitschke in his genus Carpocapsa, but in- 

 dependent of the very peculiar markings on the anterior wings, 

 the structure of the palpi does not warrant such a location ; the 

 middle joint of these organs in this genus is five times as long as 

 the apical, whilst in Carpocapsa it is only twice the length ; the 

 maxillae too are longer in the latter genus. The larva is un- 

 known. 



There is another species on the continent, R. Boisduvaliana.

 nigro atroque punctatis, basi lineis tribus longitudinalibus, strigis 

 arcuatis punctisque casruleis ; medio litura albida ; posticis nigro- 

 fuHginosis. tf Exp. al. 7-g 8 lin. 



Head dull brown, paler behind, whitish behind the eyes. Face 

 drab. Eyes black. Palpi drab, the apex dusky, the apical joint 

 black. Antennae umber. Thorax glossy, dusky brown, with a few 

 orange scales at the sides, towards the apex. Patagia dusky brown, 

 mixed with ochreous or orange. Anterior wings dull ; rich orange, 

 clouded with umber and with metallic-lustred blue markings ; at 

 the base are three thick, lustrous blue streaks edged with umber, 

 placed longitudinally, and extending one-fourth the length of the 

 wing, one on the eosta, the second through the middle of the base, 

 and the third (a less distinct one) within the dorsal margin ; before 

 the middle is a similar- coloured concave streak, reaching from the 

 costa to the dorsal margin, and another very curved one in the apical
