TORTKICINA. 101 



stant in size and colour. It is most nearly allied to H. turbi- 

 dana, but smaller, and never so darkly coloured. 



The imago appears in July, and occurs in the west and south- 

 west of England, New Forest, near Folkestone, Dover, and Deal ; 

 at Darenth, Ripley, and a few other places ; but always attached 

 to the above-named plant, in the roots or stems of which the 

 larva is supposed to feed. 



9. fcenella, Linn. Alis anticis obscure brunneo-fuscis, postica ad 

 angulum analem cinerea, macula dorsali tibialiformi alba ; posticis 

 fuscis. cf Exp. al. 10^-11 lin. 



Head drabby brown. Face paler above, white below. Eyes black, 

 sometimes purplish brown. Palpi as long as the head, drab above, 

 beneath and between, darker at the sides. Antennae dull fuscous, 

 paler beneath ; the basal joint is clothed with shining scales. Thorax 

 fuscous, the crest rich chocolate. Patagia same colour as the thorax, 

 but slightly paler at the base. Anterior wings rich chocolate-brown, 

 with an immaculate white, curved marking on the dorsal margin, in 

 shape like a bird's head and neck, with the beak towards the apex. 

 The wing towards the costa is greyish ; the costa itself chocolate, and 

 streaked throughout, the streaks beyond the middle being geminated ; 

 the apical spot distinct. The ocelloid patch is of irregular shape, edged 

 inwardly with white, and consisting of two lustrous leaden-coloured 

 clouds with a yellowish streak between, on which are several black 

 spots with pale borders. Apical scales iron-grey, darkest at the 

 apex, tipped with white. Cilia fuscous, speckled with white, and 

 becoming paler towards the anal angle. Posterior wings glossy, rich 

 golden brown. Marginal scales of same colour, with the bases straw- 

 colour. Cilia pale fuscous, the bases dull straw-colour. Abdomen 

 fuscous, the caudal tuft rich brown. $ Exp. al. 10-13 lin. In 

 colour paler than the <$ , especially along the costal portion of the 

 wing. 



Not of very frequent occurrence; variable in size, but tole- 

 rably constant in colour and markings. In some instances the 

 pale blotch is suffused with fuscous, so as to be but slightly 

 discernible from the rest of the wing. Distinguished from its 

 congeners by the shape of the dorsal blotch. 



The imago appears in June and July ; occurring in England 

 in the South and Midland Counties ; also in Norfolk and Cam- 

 bridge. 



The pupa is 6 lines long ; in shape compressed from the sides, 

 and somewhat isometric. The head, thorax, and wing-cases 

 shining, smooth, and black, the pale marks of the anterior wings 

 distinctly seen through the latter ; the abdominal portion pale 

 hazel on the ventral, and deep red-brown on the dorsal surface ;
