676 TINEINA [HELIODINES 



costa, 8 absent. Hindwings J, lanceolate, cilia 3; transverse 

 vein partly absent, 4 absent, 6 and 7 approximated. 



There is only one known species. Imago with forewings 

 lanceolate. 



1. H. roesella, L. 10-11 mm. Head and thorax metallic 

 dark bronzy-fuscous. Forewings deep orange, margins narrowly 

 blackish ; an oblique mark from base of costa, a narrow fascia 

 at J, three posterior costal spots, a triangular tornal spot, and 

 small subapical spot leaden-rnetallic, black-edged. Hindwings 

 dark fuscous. 



Said to have been formerly taken near London, record prob- 

 ably authentic ; C. Europe, WC. Asia to Turkestan ; 7, 8. 

 Larva pale green ; dorsal line darker ; head black ; 2 with two 

 black spots : amongst spun leaves of Atriplex and Chenopodium ; 

 6. 



12. PANCALIA, Curt. 



Antennae -J, in <$ rather thick, very shortly ciliated, basal 

 joint rather long. Labial palpi very long, recurved, second 

 joint somewhat loosely scaled beneath, terminal shorter, acute. 

 Posterior tibiae rough -haired. Forewings with scale-tufts on 

 surface : Ib furcate, 7 and 8 stalked, 7 to costa. Hindwings 

 almost 1, lanceolate, cilia 2 ; 6 absent. 



It is probable that the three supposed different forms of 

 this genus constitute only one species. Imago with forewings 

 elongate-lanceolate. 



1. P. leuwenhoekella, L. (latreillella, Curt.) 9-13 mm. 

 Head and thorax dark bronzy-metallic. Antennae usually with 

 white subapical band. Forewings deep orange, margins more or 

 less blackish; a narrow interrupted fascia at J, a costal spot before 

 middle and another inwardly oblique at f , a dorsal median spot, 

 and an erect tornal mark pale golden -metallic, blackish -edged ; 

 a whitish spot in cilia on posterior costal spot. Hindwings 

 rather dark bronzy-fuscous. 



Britain to the Clyde, somewhat local ; Europe, Asia Minor ; 

 5, 6. Larva dull purple - reddish, segmental incisions and 

 wrinkles pale brownish -ochreous ; head pale yellowish -brown, 

 darker-marked ; plate of 2 transparent : in leaf-stalks, after- 

 wards in silken galleries amongst rootstock of Viola hirta; 6-8. 

 The imago flies in afternoon sunshine. 



13. CHRYSOCLISTA, Stt. 



Antennae i to almost 1, in $ simple. Labial palpi long, 

 recurved, second joint loosely scaled beneath towards apex,
