The protective mimicry of these five species is very striking. 

 Both in shape and colour they resemble the glumes of the 

 flower-spikes of the grasses among which they live, as well green 

 as ripened.

 off Ononis arvensis, one, 25th July, 1887. 



Mr. Saunders writes : ' I do not feel sure that this is not a 

 female saundersi. The two species are very closely allied in the 

 female.'

 19th July, 1885. Well; plentiful, 1 6th August, 1888.
