TORTRIC1NA. 249 



otherwise very undulate ; near the apex, on the costa, is a short 

 truncate patch, of the width of the central fascia, and directed to- 

 wards it. The costal and dorsal margins between the markings 

 speckled with black ; the anal angle and apical region thickly studded 

 with dark iron-grey freckles, disposed somewhat in transverse lines ; 

 apical margin white. In an oblique direction the principal markings 

 have a rich golden-brown appearance. Apical scales very pale fawn- 

 colour. Cilia darker. Posterior wings pearly white, with numerous 

 grey freckles over the surface, especially towards the apex. Marginal 

 scales and cilia very glossy, white. Abdomen glossy, umbreous ; 

 the segments fringed with long drab scales ; the caudal tuft pale 

 drab. $ Exp. al. 8 lin. Anterior and posterior wings as in the tf . 

 Abdomen glossy, dark grey; the segments more fringed and paler 

 than in the tf ; apex obtuse and whitish. 



First captured in 1 857 by the Rev. J. C. Tress Beale, " on the 

 sloping bank of a field at Alkhara, near Dover," in July. The 

 figure in the frontispiece of the 'Entomologist's Annual' for 

 1858, fig. 4, gives a most excellent idea of this insect. It is 

 abundantly distinct from all the other British species of the 

 genus, and easily recognized by its pearly-white under-winys. 



2. hybridana, Hub. Alis anticis ochraceo-albis ; fasciis tribus, macu-

 posticis fusco-griseis. tf Exp. al. 7-7^- lin. 



Head and face fuscous. Eyes black. Palpi as long as the head, 

 fuscous. Antenna? fuscous. Thorax and patagia golden brown, speckled 

 with chocolate. Anterior wings glossy, cream-colour, pale drab, 

 with a patch at the base, a broad irregular fascia in the middle, an- 

 other near the apex, and with a patch at the anal angle, in different 

 specimens more or less produced towards the middle of the disk, all 

 pale fuscous, and more or less speckled and edged with chocolate- 

 colour ; viewed in an oblique direction, the dark markings assume a 

 dull golden lustre. The basal patch extends one-fifth along the 

 costa, and attains the opposite margin nearer the base with a rounded 

 undulating edge. The central fascia is of nearly equal width through- 

 out, hollowed and angulated on its anterior edge, and on its posterior 

 border (where it is not so sharply defined) ; it is produced into an 

 acute angle before the middle ; the apical mark reaches near to the 

 anal angle, and dilates in the middle ; the patch at the anal angle is 

 somewhat triangular in shape, but not always well defined. The 

 costa is speckled, and between the central fascia and the apical mark 

 are two conspicuous triangular fuscous spots. The pale portions of 

 the wing speckled, or faintly streaked, with pale fuscous. Apical 

 scales cream- colour, variably freckled or spotted with brown. Cilia 

 cream-colour. Posterior wings glossy, fuscous grey. Marginal scales 

 pale fuscous, with paler bases. Cilia cream-colour. Abdomen fuscous,
