BY T. G. SLOANE. 599 



intercoxal part cordiform, narrow and longitudinally sulcate 

 anteriorly; pro-episterna smooth; lateral cavities of peduncle 

 smooth; metasternum longer between median and posterior coxal 

 cavities than the length of the posterior coxge; legs stout : 

 anterior tibiae strongly 3-dentate; intermediate tibia? thick, wide 

 at apex, a strong obtuse external spur at apex: posterior tibia- 

 short, incrassate. Black. 



Head not large (1-6 mm. across eyes); front strongly rugose; 

 clypeus with median part deeply emarginate, lateral parts 

 rounded externally, not divided from median part on anterior mar- 

 gin, concave, the inner margin of this concavity sharply defining 

 the median part; supra-antennal plates large, rounded externallv 

 divided from lateral parts of clypeus by a sinuositj-; eyes globose, 

 prominent. Labrum 7-setose. Palpi stout. Antenna' shoit, 

 moniliform, incrassate, second joint longer than third. Pro- 

 thorax smooth, convex, broader than long (2-1 x 2*75 mm.), 

 widest just before posterior marginal puncture, strongly and 

 roundly narrowed anteriorly (ant. width 1-7 mm.); basal curve 

 short; anterior margin truncate; anterior line deeply impressed: 

 lateral channel wide; border strongly developed, particularly on 

 each .side of basal curve, not sinuate on each side of base, inner 

 basal angles not marked. Elytra truncate-oval (5x2-9 mm.), 

 convex, abruptly declivous at base, strongly declivous to apex; 

 strise deep, strongly punctate the punctures reaching apical 

 extremity — seventh entire; interstices convex, sixth and seventh 

 uniting at base to enclose sixth stria, eighth narrow on apical 

 curve. Intercoxal declivity of prosternum narrowed and strongh' 

 transversely sulcate in middle. Anterior femora short, thick, 

 compressed; anterior tibiae stout, strongly 3-dentate, apex stout 

 and curving outwards; posterior trochanters shortly subreniform, 

 obtusely pointed at apex. Length, 8-6, breadth 29 mm. 



Hah. — Northern Territory. Type in Coll. Sloane (unique); 

 given to me by Mr. C. French. 



A ver}' remarkable and isolated species, representing a new 

 genus among the Australian Clivinides. The head difl'ers from 

 that of all Australian species of CJivina by the strong rugosity 

 of the front; the clypeus, too, is more triangularly emarginate
