Coleoptera, Part I. 123 



Hab.—^.W. Australia : Upper Ord River (R. Helms). 



In general appearance much the same as tristis, but the size 

 much smaller, the head considerably larger and the prothorax 

 decidedly transverse. 



Lithocharis tristis, IVIacl. 



No part of this insect could fairly be called " black." Its 

 darkest part (the upper surface of the head) is piceous-brown. 

 I have specimens from the Clarence and Hawkesbury Rivers. 



Bledius seniicircu/aris, n. sp. 



Piceoiis-black, apex and sides of elytra and appendages 

 flavous, tibiae and terminal joints of antennae slightly infuscate. 

 Clothed with moderately long whitish pubescence, becoming 

 golden on head and abdomen, on the latter longer and sparser 

 than elsewhere. 



Head with moderately small and rather sparse punctures, and 

 with dense minute punctures ; antennary tubercles prominent 

 and tipped with red. Clypeus with denser punctures than else- 

 where, its sutures distinct. Antennae rather long, first joint 

 almost as long as the second to fifth combined, second as long as 

 the third and fourth combined. Prothorax moderately trans- 

 verse, subcordate, base largely and suddenly narrowed, with a 

 narrow and moderately deep continuous median line : with small 

 depressed minutely punctured granules, the interspaces of equal 

 size and equally punctate. Elytra wider and about once and 

 one-fourth longer than prothorax, sides parallel, each feebly 

 separately rounded at apex ; densely and moderately finely punc- 

 tate. Abdomen feebly dilated from base to beyond middle, 

 each segment very feebly transversely corrugated and sparsely 

 punctate, the margins distinctly punctate ; under surface 

 scarcely corrugated, but with dense minute punctures, in addi- 

 tion to the small ones. Length 5, to apex of elytra 3 mm. 



Hah. — Queensland : Brisbane (A. J. Coates). 



The shape and punctures of the prothorax and colour of the 

 elytra should render this a remarkably distinct species. The pro- 

 thorax can scarcely be called granulate, though from some direc- 

 tions it appears to be so, the elytral punctures cause a some-
