222 ON THE CARENIDES (FAM. CARABID.K), 



diverging continuously backwards, anterior part linear ; space 

 between frontal sulci convex; clypeus strongly declivous, median 

 part trisinuate (sinuosities deep, equal, rounded), intermediate 

 angles prominent, triangular ; preocular sulcus well marked, 

 oblique ; preocular pi'ocess small, rounded and not the least 

 angulate externally; eyes deeply set in orbits. Palpi with apical 

 joints securiform; maxillary moderately so, labial very widely so 

 and longer than penultimate. Antennae subfiliform, rather stout; 

 joints 5-11 compressed, sparsely setigerous and punctate on edges, 

 apical joint mUch longer than penultimate, narrowed to apex. 

 Prothorax of same width as head, as long as broad (6 5 x 6 '5 mm.), 

 widest about anterior third, lightly narrowed to base; anterior 

 margin truncate ; anterior angles obtuse, not advanced ; base 

 rounded ; basal angles widely rounded ; border thick, strongly 

 reflexed and crenulate at basal angles; marginal channel wide, 

 not interrupted at basal angles, extending along base ; one 

 marginal puncture on each side about posterior third. Elytra 

 hardly wider than prothorax (14x6'8 mm.), parallel, widely 

 rounded at apex, deeply and widely retuse at base; shoulders very 

 prominent ; dorsal surface depressed ; suture deeply impressed, 

 especially towards apex ; sides and apex strongly and roundly 

 declivous; base deepl}'' and strongly declivous; border wide, widest 

 on each side of apex, widely and strongly upturned (not dentiform) 

 at humeral angles; a row of ocellate punctures along sides in 

 lateral channel; four or five punctures in a single row on basal 

 declivity. Yentral segments impunctate; suture between second 

 and third entire. Legs not long; anterior femora rather long, 

 thick, lightly compressed, not dilatate; channelled on lower side; 

 anterior tibia? light, bidentate (the teeth long), inferior ridge 

 weakly developed, apical plate small with short triangular pro- 

 jection at apex. 



Length 27, breadth 6-8. 



Hah. — Central Australia, MacDonnell Ranges (Coll. French). 



This is an isolated species among the described Carenides, its 

 prothorax and elytra having a general resemblance to those of 

 Seocarenum hiackhurni, SI., while the head is that of a Eiitoma.
