90 NOTES ON AUSTRALIAN COLEOPTERA, 



angles are peculiar, the side and base meeting in a slightly obtuse 

 angle, the extreme point of which, however, is minutely but 

 abruptly sharpened and turned outward. The anterior tarsi of 

 the male (as usual in Trechus) have their basal two joints (only) 

 dilated and spongiose beneath. The apex of the hind body is a 

 little protruded beyond the elytra as in many other species of 

 Trechus, especially in the females. The facies of this species is of 

 Bemhidium rather than Trechus, but the structure of its palpi will 

 of course at once distinguish it from Bemhidium.

T. SiMSONi, sp.nov. 



Minus elongatus ; minus depressus ; nitidus ; luride brunneus, 



capite prothorace et pone medium elytris insequaliter sub- 



maculatim infuscatis, elytrorum striis nigricantibus, tibiarum 



parte inferior! et tarsis quam femora magis obscuris, antennis 



basi excepta brunneo-piceis ; prothorace vix transverso, postice 



fortiter angustato, lateribus antice sat fortiter rotundatis 



postice sinuatis, angulis posticis rectis, foveis basalibus 



elongatis Isevibus ; elytris breviter ovalibus, fortiter striatis, 



disco utrinque fortiter bifoveolato, interstitiis convexis, stria 



suturali sat manifesto recurva. [Long. 14, lat. y^^line (vix). 



In colour and markings very like T. Victorice (though the 



general colour being considerably darker the markings are much 



less conspicuous), but at once distinguishable from it by the 



much smaller size and very differently shaped prothorax, which is 



almost as long as wide and is much narrower across the base than 



across the front margin.

Tachys Flindersi, Blackb. 



This species seems scarcely distinguishable from Tachys (Bem- 

 hidium) rubicundus, Mack, which latter, however, is a nom. 

 prcBocc, having been used by Chaudoir for an Asiatic sp. (1850).
