truncate, angles obtusely rectangular; median line lightly im- 

 pressed ; lateral basal impressions strongly developed, widely 

 foveiform. Elytra ovate (2x1 '4: mm.), a little convex on disc, 

 gently declivous to sides, more strongly so to apex; base truncate, 

 humeral angles rounded; apical curve short; stride lightly im- 

 pressed, seventh distinct for whole length, eighth strongly 

 impressed; interstices depressed. Length 3-2, breadth 1-4 mm. 



Hah. : N.S. Wales — Mulwala (Sloane; three specimens under 

 bark of trees where they had taken refuge from the flood waters 

 of the Murray River, July 11th, 1894.) 



The affinity of this small species is evidently to Tk. britnuicofor, 

 SI., which it resembles in facies. Diiferences to which attention 

 may be directed are its less robust form, smaller size, lighter 

 colour; the prothorax with the sides less subsinuate near the basal 

 angles (these less rectangular), the concave depression at each 

 side of the base (in Tk. brurmicolor the prothorax is flattened 

 near each basal angle); the elytra less strongly striate and without 

 a striole at base of second interstice. In none of my specimens 

 are the anterior tarsi dilatate. It has a decided superficial 

 resemblance to Tachys trausversicollis, Macl. 



Thenarotes margin atus. 

 JJarplaner marginatus, Macl., P.L..S.KS.W. 1888, (2) iii. p. 472. 



A specimen of Narplaner marginatus, Macl., a cotype from 

 the Macleay Collection, is before me; it is a Thenarotes. The 

 dilatation of the four anterior tarsi in the ^ is as in Thenarotes 

 tasmanictcs, Bates, except that the fourth joint of the anterior 

 tarsi is deeply excised (almost <-shaped) and the corresponding 

 joint of the intermediate tarsi a little more lightly so; the fourth 

 joint of the posterior tarsi is entire.
