778 TINEINA [OCHSENHKIMERIA 



Hindwings 1, elongate-ovate, cilia J-l ; 3 sometimes absent, 6 

 and 7 stalked or coincident. 



A genus of few species, apparently confined to Europe. 

 They frequent grass-fields, and fly freely in the middle of the 

 day (12 to 2 P.M.), but are seldom met with at other times. 

 Imago with forewings elongate, apex pointed. Larva feeding 

 in stems of grasses. 



1. Antennae more or less thickened with scales . 2. 



not thickened . . .3. vacculella. 



2. Hindwings with transparent basal patch . 1. birdella. 



only thinly scaled towards base 2. bisontella. 



1. 0. birdella, Curt. 11-12 mm. Antennae thickened with 

 rough scales to above middle. Forewings fuscous or ochreous- 

 fuscous, mixed with lighter and darker, and with loosely raised 

 scales. Hindwings rather dark purplish -fuscous, becoming 

 transparent on a patch towards base. 



England, N. and E. Ireland, local ; Germany ; 7, 8. Larva 

 slender, whitish-yellowish ; head pale yellow-brownish : in stems 

 of grasses (Dactylis, JBromus, Poa, etc.) ; 5. 



2. 0. bisontella, Z. 9-12 mm. Antennae in $ hardly, in $ 

 rather strongly thickened with rough scales to above middle. 

 Forewings narrower than in 0. birdella, in < rather dark 

 fuscous, in $ greyish-ochreous more or less mixed with fuscous. 

 Hindwings brassy-purplish-fuscous, thinly scaled towards base. 



Britain to Stirling, local ; C. Europe ; 7. 



3. 0. vacculella, F.R. 11-12 mm. Antennae not thickened. 

 Forewings fuscous or greyish-ochreous, mixed or almost wholly 

 suffused with dark fuscous. Hindwings rather dark fuscous, 

 basal third transparent. 



England to Durham, under dead bark of trees and in houses, 

 local and uncommon ; C. Europe ; 7, 8. Larva described as 

 pale ochreous, with brown head, feeding in stems of rye, but it 

 seems doubtful whether the species was rightly identified. 



31. SCARDIA, Tr. 



Head rough. Tongue short. Antennae f, in $ shortly 

 ciliated, basal joint with pecten. Labial palpi rather long, 

 curved, ascending, second joint with projecting tuft of scales 

 beneath, terminal joint as long as second, rather pointed. 

 Maxillary palpi short, porrected. Posterior tibiae hairy. Fore- 

 wings : Ib furcate, 7 to costa, 8 arid 9 sometimes stalked. 

 Hindwings 1, elongate -ovate, cilia J; 5 and 6 somewhat 

 approximated.
