The extraordinary elongation of the head of Ceria, which 

 forms a horn at the fore part, longer in some than in other 

 species, will be an unerring mark to characterize the genus : 

 the nervures of the wings are also peculiar as well as the in- 

 crassated basal angles of the abdomen. 



Upon the continent two other species are known and de- 

 scribed, one distinguished by a short peduncle (as the pro- 

 cess has been called) to the antennae, the other by the legs 

 being entirely yellow, characters which might easily be over- 

 looked by those who are not acquainted with the specific di- 

 stinctions. The only species at present detected in this coun- 

 try is C. co7iopsoides, of which the female figured in the plate, 

 presented by Dr. Leach to the British Museum many years 

 back, is the only indigenous specimen that has come to our 

 knowledge ; and I regret that I am not able to give its locality 

 or any satisfactory account of its capture : upon the continent 

 our insect is found from May to October, and is not very un- 

 common. 



The plant is Briza media (Common Quaker-grass or Mai- 

 den's Hair).
