109. Apocheima, Hb. 

 Face roughly hairy. Tongue very short or rudimentary. Palpi 

 short or moderate, porrected, rough-haired. Antennae in $ bi- 

 pectinated to apex, or with apex simple. Thorax clothed with 

 dense hairs above, with slight anterior triangular crest, beneath 

 densely hairy. Femora densely hairy ; posterior tibiae in ^ not 

 dilated, without median spurs, or rarely with spurs present but 

 short {pedaria and tartarica). Fore wings in $ without fovea ; 

 6 rarely out of 9, 10 usually anastomosing or connected with 9, 11 

 sometimes out of 10 or abSent, or running into 12, or concealed by 

 anastomosis of 10 with 12. Hind wings with 6 and 7 sometimes 

 stalked, 8 approximated to cell to middle. Female with wings 

 rudimentary or absent. 



Almost confined to the European region ; it is de- 

 veloped from Biston. The variation in structure is rather 

 considerable, but not available lor generic subdivision.

Face rough-haired, with horny triang^^lar projection. Tongue 

 rudimentary. Palpi rather short, porrected, rough-haired. An-

The single species is a development of Biston., from 

 which it does not greatly differ, and inhabits the shores 

 of the Mediterranean.
