174 ON THE AUSTRALIAN CLIVINIDES, 



from the Gulf of Carpentaria mentioned below under C. quadra- 

 tlfrons, SI.; but, if so, the description does not aid one in deter- 

 mining it, besides the inference is that the anterior tibije are 

 3-dentate as in G. planiceps. 



Clivina quadratifrons, n.sp. 



Robust, parallel, cylindrical. Head flat, rugulose; prothorax 

 about as long as broad; elytra with fifth stria joining sixth at 

 base, eighth interstice distinctly marked on apical curve, a well- 

 developed submarginal carina at shoulders; anterior tibiae 4- 

 dentate. Black, under surface piceous, anterior legs reddish 

 piceous, four posterior legs and antennae testaceous brown. 



Head quadrate (2 x 2-1 mm.), flat, rugulose: clypeus not 

 divided from front; median part truncate; wings divided from 

 supra-antennal plates by a light linear impression, lightly and 

 obliquely advanced beyond median part, wide, truncate, external 

 angle marked, rounded; supra-antennal plates depressed, declivous 

 before eyes, divided from clypeal wing by a light sinuosit}^ 

 external margi-n sinuate; facial sulci lost in facial rugulosity; 

 facial carinte distant from eyes, feebly developed; eyes convex, 

 prominent; orbits narrow, abruptly truncate behind eyes. Man- 

 dil)les wide at base, decussating. Mentum concave; lobes rounded 

 at apex, lightly longitudinallj^ striate; median tooth large, rounded 

 at apex. Prothoi'ax of almost equal length and breadth

 anterior angles obtuse; postei'ior angles not marked; border wide 

 and explanate near anterior angles, narrow backwards, not inter- 

 rupted at posterior angles; median and anterior lines well marked; 

 lateral basal impressions short, shallow, subfoveiform. Elytra 

 parallel, cylindrical (8-5 x 4 mm.), truncate on base; striae entire, 

 lightly crenulate, deeply impressed, becoming shallow towards 

 apex, first outturned to join second at liase, fourth free at base; 

 interstices lightly convex, eighth forming a narrow carina on 

 apical curve; border narrow. Prosternum protuberant; inter- 

 coxal part very wide in front, widely and lightly channelled.
