tiiiiii as suggested by Sc-liaum; Cratoceriiii (as typified by the genus Basolia) 

 comes into the Carabidae uniperforate ; Mormolyeini, Agriini, Anthiini, Graph- 

 ipterini, and Oithogonini, all of which I have examined, belong to the Carabidae 

 biperforatae. 



With regard to the plan of having- names for the six great sections into which 

 the system here advocated divides the Carabidae, it has seemed to me that an 

 undoubted benefit of definiteness results from its use, therefore I hope ii will 

 prove acce]3table to Carabophiles. 



Middle co.ral cavities. As a matter of some interest it may be placed on 

 record that in the Carabidae generally (inclnding Metrius) the middle coxal cavi- 

 ties are confluent, the mesosternum being arched to cover the opening between 

 the cavities by its meetins; with the metasternum between the coxae; but, m. the 

 tribe Ozaenini. as far as I have observed, each coxal cavity is completely de- 

 fuied, and separated from the other by a chitinous partition, as a result of the 

 close and continuous attachment of the mesosternum and metasternum. Further 

 investigation on this subject is required, both in the Carabidae generally, and in 

 the Ozaenini, where my observations have been confined to two species, viz., 

 Pseudozaeua orientalis Klug., and Mystropomus subcostatus Chaud. 



Anterior tibiae. — The spurs and their position. Hitherto authors seem to 

 have recognised practically only two plans, as far as the position of the two 

 spurs of the anterior tibiae are concerned, viz, (1) both terminal (as in Cara- 

 6ms), (2) one above the other (as in the Scaritini) ; but there is a want of exact- 

 ness about this statement of the case, as may be readily seen Ijy anyone who 

 will examine the position of the spurs in the tribes Ozaenini, Carabini, and Scari- 

 tini, not to mention others. One of the spurs never varies in its position 

 throughout the Carabidae, it is always at the inner side of the apex of the 

 tibia ; in the tribes Metriini and Ozaenini, the other spur is opposite the inner 

 one at the outer side of the apex; here there can be no question as to both 

 spurs lieing terminal, nor as to which is the inner, and which the outer. An ex- 

 amination of any member of the tribe Carabini will show that it is the spur 

 corresponding to the outer one in the Ozaenini that is the one which, by a 

 change in position, becomes placed on the lower side of the tibia, a little ob- 

 liquely above the inner spur; it is far moi'e distant from the apex in the Scari- 

 tini and other tribes. Dr. G. H. Horn habitually used the term "inner" for 

 the spur which varies in position; this is evidently an erroneous term, and seeing 

 that in e\ery case, where it is not opposite the inner spur at the outer side of 

 the ajiex. it is more or less above the apex, the term upper would seem more 

 suitable for it ; also I think the words "both spurs terminal" can only accurately 

 be applied to the tibiae in the tribes Metriini and Ozaenini. AVhether the posi- 

 tion of the spurs in Metriini and Ozaenini implies any relationship between these 

 tribes T am not prepared to say, but I believe the form of the anterior tibiae 

 found ill these two tribes is the most archaic now existing, and I attach a high 

 value to it. 



CO-MPONENTS OF THE TaSMAXIAN CARAB-FAUNA. 



Tile Carab-faura of Tasmania includes 18 tribes, 60 genera, and 183 species 

 [and there are. besides, 1 tribe (Chlaeniiiii), 1 genus {Chlaeiiins) and 9 species re- 

 ported from the islands of Bass Strait; also, the introduced Laemostenwi eoni- 

 planati(s Dej.] Two tribes, 8 genera, and 59 species have not yet been found 

 on the mainland of Australia; this endemic part of the fauna is essentially
