158 ON THE AUSTRALIAN CLIVINIDES, 



some apparent differences between them see description of C. 

 cribrosa (ante, p. 157). 



These species require careful study with large series of fresh 

 specimens from different localities. 



The dimensions of a specimen sent to me by Mr. Blackburn are: 

 length 7; head 1-2 x 1-4; proth. 1-6 x 1-75; el. 4x1-9 mm. 



Hab. : South Australia — Adelaide, Port Lincoln (Blackburn); 

 Victoria — Melbourne (Kershaw).

 intercoxal part very narrow anteriorly, sulcate on base; episterna 

 hardly rugulose, very finely transversely striolate; anterior tibiae 

 4-dentate. Black. 



Head large, finely punctate on base of clypeus and middle of 

 front; vertex and occij)ut very convex, not punctate; a wide 

 shallow impression between cl3^peus and front: clypeus deeply 

 declivous and rugose to median part, this narrow, strongly emargi- 

 nate, its angles not marked; wings small, anterior margin sloping 

 roundly and very lightly backwards from median part; supra- 

 antennal plates rounded, bordered, divided from wings of 

 clypeus by a light sinuosity, a submarginal ridge extending 

 backwards from this sinuosity; facial sulci lightly impressed, 

 recurved part elongate and very distinct ; facial carinas 

 short, strong ; eyes very depressed. Prothorax transverse 

 (1-75 X 1-9 mm.), widely convex, strongly declivous to base, 

 smooth anteriorly, rugose-punctate towards sides of disc; sides
