NOTES ON TORTRIX PRONUBANA, Hb. 

 33T EUSTACE E. BANKES, M.A., F.E.S. 



At the request of Mr. W. H. B. Fletcher, who has most gene- 

 rously added to my collectiou the example of Tortrix pronuhana re- 

 corded by him in Ent. Mo. Mag., ser. 2, xvi, 276 (1905), I append 

 some information about this handsome species, which may be readily 

 recognised by the rich orange colour of the hind-wings. These 

 notes are mainly an abridgement from the more detailed account of 

 it given by Milliere in his " Iconographie et Description de Chenilles 

 et Lepidopteres Inedits," i, pp. 382-5 (1859), but the description of 

 the imago (J*) is made from the Bognor specimen. 



IMAGO. 



(J. Exp. al., 15-7 mm. Antennae moderately ciliated, dark brown, annulated 

 ■with whitish, with a wliitish lateral stripe from base to apex externally. Head and 

 thorax dark red-brown. Fore-wings rich brownish-grey with two oblique dark red- 

 brown fasciae, one stretching from the middle of the costa, where it is narrowest, to 

 the tornus, above which it unites with the other, which extends broadly along the 

 termen, being widest on the costa, and obscurely reticulated with bluish-grey ; 

 dorsum dark red-brown towards the middle ; cilia ochreous-red, more red at the 

 base, but blackish-grey at the tornus. Hind-ioings rich orange, with a broad black 

 marginal line, and some scattered black scales ; cilia orange, with a deep orange 

 basal line dusted with black along the middle. Underside of both fore- and hind- 

 wings rich orange, with the dorsum and lower half of the termen of the former 

 broadly blackish-brown, this colour stretching far up the wing above the tornus ; 

 cilia of all the wings rich orange, slightly deeper at the base, but blackish-brown at 

 the tornus of the fore-wing. Abdomen black, ringed with ochreous ; anal tuft orange. 

 The 9 J according to Milliere, is a little larger than the ^ > and is paler, es- 

 pecially on the fore-wings, on the under-sides of which the dorsal margins, instead of 

 being broadly black, are merely tinged with dark grey. 



Von Heinemann (Schmet. Deutsch. u. d. Schweiz, Kleinschmet., 

 B. i, H. i, pp. 37 — 8) says that the ground-colour of the fore-wings 

 varies from ochre-yellow to cinnamon-brown, and I gather that their 

 markings are also rather variable. 



LARYA. 

 Fusiform, wholly green. Dorsal area, between the subdorsal lines, from the 

 2nd to the 10th segment, dark green. Lateral area, between the subdorsal and 

 the spiracular lines, glaucous-green. The spiracular line alone is well defined ; it is 

 broad, continuous, wavy, and yellowish-green. Ventral surface inclining to bluish. 

 Head large, heart-shaped, testaceous, bordered with brown from cheek to cheek. 

 Ocelli large, black. Prothoracic plate with three cuneiform spots pointing for- 

 wards. Spiracles minute, white, black-ringed. Trapezoidals pale green, fairly 

 distinct. Hairs long, whitish. Legs and prolegs greenish (Milliere's description 

 condensed) .
