164 ON THE AUSTRALIAN CLIVINIDES, 



though he places C. ohliquata in a group characterised by the 

 fifth stria, not the fourth, reaching the eighth interstice, he says, 

 in the description, that the fourth unites more or less distitictly 

 with the eighth at the base; in C. ohliquata it turns out at the 

 base, but does not actually join the fifth. 



Clivina debilis, Blackburn. 



P.L.S.N.S.W. 1889 (2), iv. p. 722. 



Black, legs testaceous. Narrow, elongate, subdepressed. 

 Clypeus with median part truncate, hardly distinct from wings, 

 its angles very weak; wings truncate, external angles squarely 

 obtuse; supra-antennal plates projecting strongly beyond wings of 

 clypeus. Prothorax quadrate (12 x 11 mm.). Elytra parallel 

 (2'8 X 1"3 mm.); fifth stria joining sixth at base, seventh well 

 marked in all its course. Prosternum with intercoxal part very 

 narrow anteriorly, transversely sulcate on base. Anterior tibiae 

 narrow, 3-dentate (only an obsolete trace of an upper prominence). 



Length 5, breadth 1-3 mm. 



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



Closely allied to C obliquata, Putz., from which its small size 

 will at once distinguish it. The description above is founded 

 on a specimen for which I am indebted to Rev. T. Blackburn. 



A specimen brought from Lake Callabonna (Central Australia) 

 by Mr. A. Zietz, in 1893, differs slightly, being a little larger 

 (5"3 X 1'4 mm.), and having the pi-othorax with longer sides (basal 

 curve short), (1-4x12 mm.), the disc punctate near the sides; the 

 angles of the median part of the clypeus more prominent, the 

 " wings " more angulate, kc. It may be a different, but closely 

 allied species ; to study it satisfactorily several specimens would 

 be necessary. 



Clivina riverine, n.sp. 



Wide, parallel, very depressed. Prothorax quadrate; elytra, 

 punctate-striate, four inner stripe free at base; prosternum with 

 intercoxal part very narrow anteriorly, transversely sulcate on 

 base; anterior tibitv 3-dentate. Black, shining, legs piceous.
