Large, powerful ; segments 4 and 5 of antennae equally long,, 

 together longer than 3. Head tuuiid, sutures deep. Pronotum 

 as wide as the head, not broadened posteriorly. Elytra ample,

 depressed, elongate, toothed. 



Range. Oriental Region. 



This genus is very inaptly named by Verha3fF, who gives it a 

 diminutive tei-mination, though it includes the largest species of 

 the family, and one of the largest known species of earwigs. It 

 is characterixed by the broadened elytra with a sharp and distinct 

 keel running the entire length of the costal fold. 



It would appear that Verhceft' was familiar only with the typical 

 species, as it must have been by guess-work that he included 

 Chelisoches pyulcliripennis, Borm., and Ch. ghmcopterus, Borm., on 

 the strength of their metallic coloration. As a matter of fact, 

 those two species have only a very short keel on the elytra, and 

 so are excluded from the genus by Verhcefi's own characterisation. 



The genus is monotypic, for the reception of Lohopliora superha, 

 Dohrn, of which Chelisoches dorice, Borm. is evidently the male. 



This is not the only member of the family in which the female 

 has highly developed "forceps, having all the appearance of a male.
