Face rounded, or with conical horny projection

Antennae 

 Forewings : 4 and 5 sometimes

 sometimes coincident, 10 rarely

A very large genus, occuri'ing 

 plentifully all over the world 

 except in Australia, where there 

 are no indigenous species, and 

 the, Indo-Malayan region, where 

 there are comparatively few. 

 The different types of frontal 



,, and antennal structure are com- 



^ pletely connected by transi- 



NeurationandheadofCram6«sc«;m«Kws. ^j^^^^j forms; the differences of 



neuration occur in different specimens of the same species. 

 The larvae probably all feed amongst stems and roots of grass 

 or on moss, but are proportionately less known than those of 

 any other considerable genus.
