Geoup CLIVINID^. 



In this group the shape of the Hgula is normal, that is to say, it 

 is not concave, and the paraglossae are partly separated, and some- 

 times very divergent from the ligula which is more or less slender ; 

 the head has a very well-defined lamina on each side from the eye 

 to the angle of the epistoma ; the eyes are prominent {Beicheia 

 excepted) and reach nearer to the epistoma ; the first joint of the 

 antennae is not so long as in the Scaritidce, the other joints are more 

 moniliform ; the head has two supra-orbital setae, and the prothorax 

 also two subapical and a postical ; the elytra are convex, sometimes 

 cylindrical. 



Sy7io])sis of Genera. 



Anterior tibise tridigitate. 



Mandibulse very long and strongly falcate ; mentum quadrate ; 

 median tooth much shorter than the lateral lobes ; paraglossse 

 slender, diverging ; ligula broad, quadrate, a little convex in the 

 median part which is less transparent than the sides Scolyphts. 



Mandibles arcuate ; mentum subquadrate ; median tooth nearly 

 as long as the lateral lobes ; paraglossae very slender and curving 

 inward, longer than the ligula which is very narrow, truncate at 

 the tip and bears four long setae Bohemania. 



Mandibles arcuate ; mentum quadrate ; median tooth as long as 

 the lateral lobes ; paraglossse short, diverging from the ligula 

 which is very narrow, and bear two long setae at tip ; prothorax 

 more or less quadrate Clivina. 



Mandibles arcuate ; mentum without a median tooth ; para- 

 glossae and ligula of Clivina ; prothorax globose Dyscliirius. 



Anterior tibse hardly without any digitation. 



Mandibles arcuate ; eyes hardly distinct . . . . Beicheia. 



Clivina is found in damp grassy places or under stones. 

 Dyschirius prefers the sandy shores of rivulets or streams, where 

 they run with rapidity and bury themselves to avoid being captured. 

 Beicheia was captured in sifting some damp mould and mosses. Of 

 the five genera included in the Clivinidce one only, Bohemania, is 

 South African ; Scolypttos is an African genus, occurring in Senegal ; 

 Clivina and Dischirius are represented in Europe, Asia, North and 

 South America, and Australia ; while Beicheia occurs in Europe 

 only. 



The dissection of the buccal organs of the species of this group is 

 by no means easy, as rightly stated by Dr. Horn (genera CarahidcB^ 

 &c., p. 121), but it is somewhat singular that the figure of the 

 mentum, ligula, and paraglossse, as given by him, should differ so 

 much from that of the South African species. Putzeys' figures of 

 some Clivince (Postcriptum ad Clivin. Monogr., figs. 43-60) seem 

 highly fanciful, but the details of the buccal organs of Bohemania 

 and Scolyptus are fairly correct.
