Mi TINKINA [antjsmla. 



species. ] mago with forewings lanceolate. Larva almost apodal, 



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



The imagos fly in sunshine. 



. Posterior costal spot triangular . . 1. pfeifferella. 



„ ,, transverse-oblong . 2. treitsehkiella. 



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

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

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

 beyond it pale golden-metallic, ilindwings dark grey. 



England to York, common; (!. 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, V'.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 ; fi. Larva grey-whitish ; 

 head and plate of 2 black ; 3-1 2 beneath each with a black 

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

 spring; case on surface of ground. 



17. AlJCiASMA, 7/.S'. 



Antennae J, in <? thick, simple. Labial palpi short, drooping, 

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

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

 absent. Ilindwings \, 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-
