narrowed, otherwise formed as in the c? , except that the external 

 depression and ridge are absent. Penultimate ventral segment in 

 the c? ample, very broadly rounded ; in the 2 similar but less 

 broadly rounded, more pronouncedly convex. Pygidium of cS and 

 $ not protruding. Porceps with the branches in the c5" remote 

 at the base, very stout and trigonal, the upper keel corre- 

 sponding to the slight tumidity of the last dorsal segment, the 

 outer surface being depressed in correspondence with the similar 

 depressed area on the last dorsal segment, the outer ridge corre- 

 ponding with the line of the points of the sixth-ninth abdominal 

 segments and lateral ridge of the last dorsal segment ; the branches 

 are straight at first, tapering rapidly; at about half their length they 

 become abruptly attenuate, cylindrical and strongly bowed inwards ; 

 the maximum breadth is over double the length. In the $ the 

 branches are contiguous, stout, trigono-conical, straight and taper- 

 ing, the inner margin crenulate.

Easily recognizable by the apically dilated abdomen. It is re- 

 lated to G. javana, Borm., and G. sumatrana, Bonn., but is smaller, 

 more shining, and the abdomen much more strongly dilated.

Type, Forficula maritima, Bon. 



Body convex, rather elongate, generally stout. Head convex, 

 longer than broad. Antennae with from 15 to 25 segments, formed 

 as in Psalis, but the form and size varies within certain limits. 

 Pronotum rectangular, almost or quite square ; mesonotum trans- 

 verse ; metanotum with posterior border sinuate. Elytra entirely 

 absent. Legs rather short, wide. Sternal plates rather narrow, 

 longer than broad. Metasternum somewhat produced between 

 posterior coxae ; the lobe generally truncate at the apex. 

 Mesosternum rounded posteriorly. Abdomen depressed, rather 

 broad, attaining its greatest breadth at about two-thirds of its 

 length ; lateral tubercles sometimes distinct, sometimes obsolete.
