516 ON CARABID.E FROM WEST AUSTRALIA, 



South-eastern Australia and the sea. I am also compelled l)y 

 want of further knowledge to restrict the term " Eyrean Sub 

 region " to that part of the continent west of the East Australian 

 Slope and south of a line drawn from Bathurst, in New South 

 Wales, to Alice Springs, and thence to Nickol Bay. 



As far as I can judge from the data available, and working 

 w'ithin the limitations laid down above, the Carabidfeof Australia 

 in their distribution show a consonance with the rest of the fauna, 

 and support the conclusions arrived at b}- Professor Spencer in 

 his able summary of the distribution of the fauna of Australia.^' 



Taking South-west Australia as here limited, the Carabidse 

 sent by Mr. Lea number 98 species, to which 10 previously 

 described species may be added as definitely recorded as having 

 been found within the area under consideration. These 108 

 species are comprised in 11 f triljes and 48 genera; the total 

 recorded numbers for Australia are 21 tribes, 160 genera, and 

 about 1320 species. These figures show that the carabideous 

 fauna of South-west Australia is poor in numbers — though doubt- 

 less it will be considerably augmented by future collecting. 



I give below four tabulated lists of the number of genera in 

 several divisions of Australia. These lists show their own results 

 and there seems no reason to allude .at all fully to them. The 

 endemic Carabidae of Australia comprise about 118 genera and 

 735 species. Tables iii. and iv. give a comparison of the 

 Carabidas of South-west Australia with a part of New South 

 Wales which may be looked upon as the extreme south-eastern 

 part of the Ej^rean Subregion, viz., an area extending from 

 Mulwala (where the 146th parallel of E. longitude cros.ses the 

 Murray River) to Junee — say a distance of 120 miles in a north- 

 easterly direction; over this area I have collected for a numl^er 

 of years with considerable care.

 N.S. W. 1897, xxii. p. 683, for a note by Mr. Fletcher on the Batrachia of 

 South- west Australia. 



t I expect that the following tribes not yet definitely recorded as occur- 

 ing in the S. VV. corner of Australia will be found thurc, viz., the Apotoniini, 

 Pogouiui, Odacanthini, Dryptini, and Hellucnini.
