GENUS ODONTOSIA. 

 Odontosia, Hiibner, Verz. bek. Schmett. p. 145 (1822?). 



This is another small genus, formerly included with Noto- 

 donta, but distinguished by its more strongly denticulated and 

 uniformly-coloured wings ; the body, too, is rather stouter and 

 shorter. The thorax has a slight crest. The typical species 

 is widely distributed in England, but not common, though it 

 is not of such extreme rarity as many of our British Noto- 

 dontidce.
