TINEINA 



[SCOLIAULA 



Neuration of ScoUaula quadn- 

 maculdla. 



out of 8, 9 absent. Hindwings ovef ^, lanceolate, cilia 2^ ; cell 

 open between 2 and 6, 3-5 absent. 



Only the one species is known ; 

 it must closely approach the 

 common ancestral form of the two 

 preceding genera. Its own oi'igin 

 is obscure, but may probably be 

 referred to a very early form of 

 the family, allied to Tinea and 

 preserving much of the ancestral 

 structure. Imago with forewings 

 lanceolate. 



1. S. quadrimaculella. Boh. 7-9 mm. Head orange, collar 

 ochreous-whitish. Antennal eyecaps ochreous-whitish. Fore- 

 wings bright shining purplish - coppery ; yellow -whitish costal 

 and dorsal opposite spots beyond middle. Hindwings dark 

 fuscous. 



England to York, amongst alder, local ; Holland, Sweden ; 7. 



4. Opostega, Z. 



Head rough, back of crown smooth. Tongue short or absent. 

 Antennae ~, in $ simple, basal joint very greatly enlarged, 

 dilated and concave beneath to form a large eyecap. Labial 

 palpi short, filiform, drooping. Maxillary palpi long, filiform, 

 folded. Abdomen more or less flattened. Posterior tibiae and 

 first joint of tarsi with long bristles. Forewings: lb simple, 

 cell open between 2 and 11, 3-10 all absent; lower surface 

 with large basal denuded patch below costa 

 narrow -lanceolate, beneath with 

 median pecten of stiff scales 

 towards base, cilia 3-5; transverse 

 vein absent between 2 and 5, 3 

 absent, 4 absent. 



A remarkable genus, repre- 

 senting the extreme of neural 

 degenei'ation ; its origin is ex- 

 ceedingly doubtful ; though not 

 large, it is probably nearly cos- 

 mopolitan, more species being at present known from Australia 

 than elsewhere. Imago with forewings lanceolate. Larva 

 almost unknown.
