This beautiful species is also peculiar to Japan and is known 

 commonly as higurashi or hanakana zemi ; the latter name being derived 

 from its screamings. It is an alpine insect, many living in deep forests 

 where sunlight does not penetrate. Its voice is heard especially at sun- 

 rise and sunset. In Hokkaido it is very common near dwellings and is 

 the earliest cicada we meet with. It cries from morn till night with its 

 peculiarly accented tone.
