40 THE VICTORIAN NATURALIST. [Vol. XXVI. 



Sound in the north-west round Australia to the mouth of the 

 Glenelg River. This coastal strip is divided by Professor Spencer 

 at the Clarence River into two parts — viz., a northern ' Torresian' 

 sub-region (in which New Guinea is included), and a southern 

 ' Bassian ' sub-region (in which Tasmania is included). 



" The ' Birchip-Sea Lake ' area partakes of the general 

 poverty in Carabid?e which characterizes the Eyrean sub-region, 

 and its Carabidse show a decided preponderance of Eyrean 

 types. Being situated near the confines of the Bassian sub-region, 

 it has naturally received more genera and species from that sub- 

 region than from the more distant Torresian sub-region. It has 

 derived from the Bassian sub-region its Nomiini (an Antarctic 

 element) and Lebiini. The Apotomini, Panageini, and Odacan- 

 thini have, no doubt, been derived indirectly from the Torresian 

 sub-region — they are Oriental tribes now distributed generally 

 over Australia. The Clivinini, Scaritini, Broscini, and Helluonini 

 are represented by forms which are essentially Eyrean. The 

 other tribes included in this local fauna are here composed of 

 ordinary Australian forms, and have such a general distribution 

 over Australia that more knowledge of the areas to which the 

 different genera and species are limited will be required before it 

 will be possible to divide them into geographical groups for the 

 study of their geographical distribution. 



"The general conclusions I arrive at from an examination of 

 Mr. Goudie's materials are — 



"i. The Carabidffi in the main are composed of elements that 

 are characteristic of the interior of extra-tropical and Western 

 Australia. 



" 2. Owing to the arid summer and the low annual rainfall 

 there is a marked absence of the types which reach their highest 

 development in the more humid forests of the adjacent Bassian 

 sub-region. — Thos. G. Sloane. 6/6/09." 



CICINDELID^. 



4. Megacephala (Tetracha) australis, Chd. (Nov.) 

 This fine species is not common in the area under notice, but 

 is said to be frequently met with along the course of the Murray, 

 under logs, &c., close to the water. 



13. Cicindela semicincta, BruUe (Nov.) 



A widely distributed species, but rare in the Mallee. Habits 

 similar to foregoing. 



CARABIDiE.

 35. Calosoma schayeri, Er. (Nov.)
