PYRALW.S—CLEDEOBIA. 367 



tubercles nearly black. In a tough, white, glossy silken 

 cocoon, in a corner or among the leaves of the food-plant ; 

 changing to pupa a day or two after finishing the cocoon. 

 (G. T. Porritt.) 



The moth hides during the day among grass in fields, and 

 especially on coast sands and cliffs, where often it is exces- 

 sively abundant, starting up at every footstep, and retreating 

 hastily to a short distance. It flies naturally at dusk and 

 through the night, and there is reason to believe that it 

 often migrates or moves about in large numbers at this 

 time, since the morning will find it occasionally in plenty 

 when there were few or none the night before. Thus I have 

 known every bit of a suburban lawn to become suddenly 

 populous, although it does not usually frequent such situa- 

 tions by any means so much as the dry fields and hill sides ; 

 while it especially favours the coast, and becomes there, from 

 its numbers, absolutely bewildering. In England it is 

 usually not very common in the Midlands, yet is found 

 throughout the British Isles to the Shetlands in varying 

 numbers. Abroad it seems to be spread over tlie temperate, 

 sub-tropical, and tropical regions of the whole world.
