The hind femora each have an almost equilaterally triangular 

 extension of the inner apex, which, however, from some directions 

 appears as a thin apical flange. It should possibl}' be regarded 

 as a tooth, but, if so, it is very different from the long and com- 

 paiatively narrow tooth so conspicuous in A. Tasmanue and the 

 following species. 



Anisotoma ammophila, n.sp. 



Reddish-castaneous, appendages somewhat paler. 

 Head with dense but veiy minute punctures. Pruthoiyi.r with 

 extremely minute punctures, scarcely visible except on sides. 

 Elytra with regular rows of distinct but small punctures, not 

 extending to base; interstices impunctate, but a few small punc- 

 tures about shoulders. Metasternum with dense punctures at 

 sides. Legx short and wide; hind femora at apex each with a 

 strong acute inner tooth; tibite wide, especially the four hind 

 ones and with short, stiff' seke. Length '2(vix)mm. 

 Hab. — Tasmania : Hobart(A. M. Lea). 



In general appearance close to A. myrmecophila and A. Tas- 

 nianicf] from the latter, distinguished by the impunctate elytral 

 interstices; and from the former, by the armed femora: the 

 femoral teeth are large, but rather shorter and stouter than in A. 

 TasmanifP.. A single specimen was taken in sand, whilst hunting 

 for species of Phycochus at Sandy Bay. 



The Australian species of this genus, at any rate those K nown 

 to me, so closely resemble each other in general outlines, that 

 they are not very easily distinguished, and the following table 

 may therefore be useful.
