T. HIS genus is more numerous in species than entomo- 

 logists at present seem to be aware of. Most of them are 

 regarded merely as varieties of the present species, and of 

 A. lipunctatum ; but they are distinguished from each other, 

 not only by the differences of colour, but likewise of shape. 

 The genus might be divided into two families ; one with a 

 straight scutellum, the other with an arched one, with the 

 carina or keel very much elevated. The present specimen is 

 most probably the Gryllus subidatus und Acrydium subulatum 

 of Degeer and Fabricius ', although Degeer does not notice 

 the black clouds which distinguish the anterior part of the 

 thorax. Our figure is taken from a specimen in the cabinet 

 of the Rev. W. Kirby. 



The body is cinereous, mottled with a darker colour; 

 the scutellum is nearly twice the length of the abdomen, 

 acuminated, with its central carina not very much elevated ; 

 its anterior part clouded a little with black. The antennae 

 are pale, with black tips.
