A small but quite cosmopolitan genus, derived from Tinea ; 

 endemic species occur in each region, but there arc others 

 whose range has been artificially extended over a large part of 

 the world. The genus shows more structural variation than 

 Tinea, especially in neuration, but the stalking of veins 3 and 

 1 of the forewings is a constant character for distinction, imago 

 with forewings elongate, rather narrow, tolerably pointed. Larva 

 feeding on dry vegetable substance and various refuse, especially 

 of an excrementitious nature.
