684 TINEINA [ANTISPILA 



species. Imago with forewings lanceolate. Larva almost apodal, 

 mining in leaves. Pupa in an oval case cut out from the leaf. 

 The images fly in sunshine. 



Posterior costal spot triangular . .1. pfeifferella. 



transverse-oblong . 2. treitschkiella. 



1. A. pfeifferella, Hb. 8-9 mm. Head dark bronzy-fuscous. 

 Forewings dark coppery-bronzy-fuscous ; a slender fascia before 

 middle, a triangular tornal spot, and a triangular costal spot 

 beyond it pale golden-metallic. Hind wings dark grey. 



England to York, common ; C. Europe, Asia Minor ; 5. 

 Larva very pale greyish-green ; head and plate of 2 pale 

 brown : in blotches in leaves of Cornus ; 7, 8. Pupal change 

 in autumn ; case subterranean. 



2. A. treitschkiella, F.R. 6 mm. Differs from A. pfeifferella 

 as follows : forewings with markings yellower-tinged, costal spot 

 more transverse-oblong, not triangular. 



England to York, local ; C. Europe ; 6. Larva grey-whitish ; 

 head and plate of 2 black; 3-12 beneath each with a black 

 dot : in blotches in leaves of Cornus ; 8, 9. Pupal change in 

 spring; case on surface of ground. 



17. AUGASMA, HS. 



Antennae J, in $ thick, simple. Labial palpi short, drooping, 

 filiform, pointed. Posterior tibiae rough-haired. Forewings : 

 Ib furcate, 3 absent, 5 absent, 6 and 7 stalked, 7 to costa, 8 

 absent. Hind wings ^, lanceolate, cilia 3 ; transverse vein partly 

 absent, 4 absent, 6 absent. 



Only the one species is known ; its exact affinities are 

 obscure. The larva is remarkable as being a true gall-pro-

 larvae themselves, and are not the work of other insects. 



18. DOUGLASIA, Stt. 



Antennae , in $ simple. Labial palpi short, porrected, 

 tolerably filiform, pointed. Posterior tibiae rough -haired.
