densely hairy beneath. Femora hairy ; posterior tibiae in $ 

 dilated. Forewings in <$ without fovea; 10 often connected 

 or anastomosing with 9, sometimes with 12 also, 11 out of 10, 

 usually anastomosing with 12, rarely with 10 also. 



Kestricted to a few species inhabiting the European region 

 and India ; derived from the Biston group. 



1. S. abruptaria, Thnb. 29-35 mm. Forewings pale ochreous;

 Ligustrum, rose, etc. ; 6-8. The imago when at rest with 

 outstretched wings appears to imitate a wood-growing fungus. 



10. ABRAXAS, Lch. 



Face smooth. Tongue developed. Antennae in <$ stout, 

 ciliated with fascicles. Palpi shortly rough-scaled. Thorax 

 hairy beneath. Femora glabrous ; posterior tibiae in dilated. 

 Forewings in $ without fovea ; 10 sometimes connected with 9, 

 11 out of 10, anastomosing with or running into 12, or absent. 



A genus of rather limited extent, mainly Asiatic.

1. A. grossulariata, L. 36-43 mm. Head black. Thorax 

 and abdomen light orange, spotted with black. Forewings 

 ochreous-white ; first line curved, very near base, second sinuate, 

 orange, margined with rows of subconfluent black spots ; a 

 sinuate median, and a terminal series of black spots ; sometimes
