58 TORTRICINA. 



with one distinct streak proceeding from it to the anal angle ; a few 

 slight reticulations at the apex. Apical scales shining yellow. Cilia 

 somewhat paler, both becoming whitish at the anal angle. Posterior 

 wings : the anal half pale dusky, the costal half white ; the apex with 

 a pale yellow tinge. Marginal scales and cilia shining white. Abdo- 

 men pale fuscous, the caudal tuft somewhat luteous. $ Exp. al. 

 8-| 9 lin. Anterior wings coloured and marked like the <5 ; but the 

 marks are very dilute and undefined. Posterior wings more dilute. 



A very rare and local species, but does not vary. 



The imago appears in July near Darenth, Mickleham, and at 

 Bordeau Hangers, near Petersfield, Hants, at which latter place 

 it was taken in July 1842 (vide ' Ann. & Mag. Nat. Hist/ 2 ser. 

 vol.v. p. 110).

Head pale ochreous on vertex, fuscous in front. Face fuscous. 

 Eyes black. Palpi longer than the head, above and between pale 

 ochreous, fuscous at sides, darkest at apex; ochreous, sometimes 

 straw-colour, beneath. Antennas straw-colour above, fuscous be- 

 neath ; basal joint fuscous above, clothed with shining pale -coloured 

 scales beneath. Thorax pale ochreous on vertex, slightly fuscous at 

 sides. Patagia ochreous, dusky at base. Anterior wings glossy 

 straw-colour, sometimes pale ochreous, with brown markings ; the 

 costal fold broadly brown at the base, followed by one or two streaks, 

 and one or two brown spots near the middle of the wing at the 

 base ; before the middle of the costa commences an angulated fascia, 

 strongly indicated at its origin, usually becoming suddenly paler in 

 its course to the dorsal margin, where it is more or less denned 

 (sometimes this fascia is represented by a few brown spots near the 

 costa, succeeded by an ochreous cloud and a dark mark on the dorsal 

 margin) : the subapical costal patch is fuscous, maculated with dark 

 brown, well-defined ; and the apical region of the wing more or less 

 dotted. Apical scales dull straw-colour ; cilia also dull, and slightly 

 paler, both merging into pale grey beyond the anal angle. Posterior 

 wings dirty white at base, with a pearly lustre, at the apex slightly 

 straw-colour, sometimes grey, and apparently maculated, from the 

 fuscous spots beneath showing through. Marginal scales and cilia 

 same colour as the wing. Abdomen and caudal tuft straw-colour or 

 pale ochreous. $ Exp. al. 9-11 lin. Head, face, thorax, and patagia 

 dull ochreous. Palpi dull ochreous, tinged with fuscous above and 

 at sides, dull straw-colour beneath. Antennas dull ochreous (some- 

 times fuscous) above, and fuscous beneath. Anterior wings glossy 

 dull ochreous. marked like the $ , but with fewer maculations at the
