Pentatomides. 
St§l, 1. c. p. 54, gives the following analysis of the genera 
which have been formed, very unnecessarily in the Recorder's 
opinion, at the expense of the genus Acanthosoma (Curt.) : — 
1. Posterior lateral margins of thorax neither dilated nor produced backward. 
A. Basal margin of thorax wider than scutellum, posterior angles produced 
into a small tooth ; anterior margin of the prostethium not produced ; 
basal joint of antennae not passing apex of head; apical margin of 
corium rounded Cyphostethus (Fieb.). 
B. Basal margin of thorax not wider than scutellum ; anterior margin of
