THAMNOTRIZON CINEBEUS 193 



There has already been much about insects in this 

 book, and it may seem that I am giving a dispropor- 

 tionate amount of space to these negligible atomies; 

 nevertheless I should not like to conclude this chapter 

 without adding an account of yet another species, one 

 indeed worthy to rank among the Insect Notables of 

 Southern England described in a former chapter. The 

 account comes best in this place, since the species had 

 seemed rare, or nowhere abundant, until, in October, I 

 found it most common in Selborne parish ; and here I 

 came to know it well, as I had come to know its great 

 green relation, Locusta viridissima, at Longparish. 

 Both are of one family, and are night singers, but the 

 Selborne insect belongs to a different genus Thamno- 

 trizon of which it is the only British representative; 

 and in colour and habits it differs widely from the green 

 grasshoppers. The members of this charming family are 

 found in all warm and temperate countries throughout 

 the world : in this island we may say that they are at 

 the extreme northern limit of their range. Of our 

 nine British species only three are found north of the 

 Thames. Thamnotrizon cinereus is one of these, but 

 is mainly a southern species, and the latest of our grass- 

 hoppers to come to maturity. In September it is full 

 grown, and may be heard until November. It is much 

 smaller than viridissima, and is very dark in colour, 

 the female, which has no vestige of wings, being of a 

 uniform deep olive-brown, except the under surface, 

 which is bright buttercup-yellow. The male, though
