252 ON THE AUSTRALIAN CLIVINIDES, 



Sydney coastal district; the Melbourne district; the southern parts 

 of South Australia, where the Rev. T. Blackburn has collected; 

 and a part of inland New South Wales \ying between Narrandera, 

 on the Murrumbidgee River, and Mulwala on the Murray, over 

 which I have collected, though not with sufficient care. Good 

 collections have also been made by Mr. Masters at Port Denison 

 and Gayndah in Queensland, and at King George's Sound; by 

 Mr. Froggatt at King's Sound; and by Mr. Lea at Tamworth in 

 New South Wales. No vise can be made by me, from want of 

 accurate knowledge, of the collections from Melbourne, South 

 Australia, Gayndah and King's Sound. 



The Clivinides are a well defined division of the subfamily 

 Scaritini. They reach their greatest development in the warm 

 parts of the earth, and it is, as might have been expected, in 

 tropical Australia that they are most numerous and show the 

 greatest diversity of form. All the Australian genera, viz, 

 Dyschirhcs, Glivina, Steganomma, and i 'Jivintrchus have represen- 

 tatives in tropical Queensland , the two last being peculiar to that 

 region. 



Dyschirius (5 species) seems spread over the continent. 



Clivina (83 species) has representatives wherever there is 

 water of any permanence all over Australia. The following are 

 a few remarks on the dispersion of the thirteen groups into which 

 I have divided the Australian species : — 



(1) C. biplajiata extends over eastern Australia from the Gulf 

 of Carpentaria to Melbourne. 



(2) The " crihrosa group " (4 species) is typically a western 

 and southern one. 6'. frenchi from Central Australia and 

 Queensland is not closely allied to the other three species. 



(3) The '^ oh/iquata group" (11 species) has its headquarters 

 in the southern and western parts of the continent. The two 

 species, C. cylindriformis and C. obsoleta, from tropical Queens- 

 land, are both isolated species, not closely allied to one another or 

 to any of the other members of the group. 



(4) C. coronata is from south-western Australia.
