Sternopriscus minimus, n.sp. 



2- Subopaque ; with very fine pubescence. Black, abdomen 

 piceous-black ; prothorax testaceous, the middle black ; elytra 

 margined with indistinct testaceous spots, head very indistinctly 

 bimaculate in front; legs testaceous, in places infuscate; antennae 

 testaceous, the apical and median joints blackish. 



Densely and minutely punctate all over. Prothorax depressed 

 on each side of base, the depressions connected together, each 

 bounded outwardly by a straight, slightly oblique ridge. All the 

 tibiie curved. Length 1| mm. 



H'lh. — Swan River, Donnybrook, W^A. 



In certain lights a; bluish iridescence may be seen on the elytra 

 and to a less extent on the prothorax. The species strongly 

 resembles Ayitiporus femoralis in miniature. 



Steknopriscus multimaculatus, Clark. — I have a specimen 

 from Whitton which I believe to belong to this species; it has 

 the terminal joint of the antennte almost as long as the three 

 preceding combined, and these are slightly thickened. 



Sternopriscus tarsalis. Sharp. — The female differs in having 

 the interinediate tarsi much shorter than in the male. The 

 transverse depression of the prothorax is usually absent, but it is 

 sometimes traceable. I have specimens from Sydney, Forest 

 Reefs and the Clarence River.
