have a strong family likeness, and are undoubtedly related 
to Apterygida. 
The type of the genus is Forficula linearis, Esch., 
Entomoer. p. 81 (1822), from Tropical America.

II. CHELISOCHIDA. 
This family includes all those earwigs in which the second 
tarsal segment is produced into a narrow lobe beneath the 
third, that is, the two species of Awchenomus, Karsch, and 
some twenty odd species included in Chelisoches, Scudd. 
The former genus requires no treatment at present; its 
species are few and individuals are rare in collections. 
The twenty odd species of the Chelisoches are here divided 
for the first time into no less than nine genera, of which 
seven are new. I hope that all will stand the test of time. 
The Chelisochidg fall into two sub-families as follows :—
