This 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. bipunctalum ; 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 subulatus and 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.
