This is the largest cicada existing in this Empire, and though 

 common in Okinawa, is not found in the north. I have no informa- 

 tion about its character, but should like to hear about it from any one 

 who has travelled in that region. I am only acquainted with its figure 

 and description as given by Distant, and it is said that Pryer has 

 collected it in Ryuku. This species is also found in Siam and China.
