group in the genus, characterised by the eyes small and distant 

 from the buccal fissure. L hrunneus may be readily distinguished 

 from Z. micans (also from the Darling River) by its smaller size; 

 olour; head more narrowed behind eyes, the *' temples " more 

 ollen; prothorax proportionately longer, less strongly rounded 

 on sides, more narrowed to base, basal angles less strongly 

 rounded, etc. 



LOXANDRUS QUADRICOLLIS, n.sp. 



Oblong-oval, convex. Eyes large, prominent, not distant from 

 buccal tissure beneath. Prothorax Isevigate, subquadrate (2-6 x 

 2 -8 mm.) with sides rounded, strongly narrowed to apex (1-75 mm.), 

 very lightly so to base (2-5 mm.); basal angles widely rounded; 

 base truncate, bordered; lateral border wide and bearing the 

 posterior marginal seta at basal angles; lateral channel wide, 

 opaque, extending to base ; median line light ; lateral basal 

 impressions elongate, linear; spaces between these and lateral 

 channel impunctate, a little convex. Elytra ovate (6-5 x 3'85mm.); 

 inner angle at shoulder formed by junction of lateral and basal 

 borders open; strife deep, crenulate; interstices lightly convex, 

 3rd unipunctate near 2nd stria a little before middle. Mesosternal 

 episterna, metasternum on each side and its episterna punctate. 

 Ventral segments rugulose-punctate. Black, iridescent ; legs 

 black, tarsi piceous; antennae dark piceous. Length 10, breadth 

 3-85 mm.

The description given above is founded on specimens from the 

 Urana District. For the validity of L. quadricollis as a species 

 distinct from L. suhiridescens, Macl., reliance is placed on its 

 larger size; more robust form; differently shaped prothorax, which 

 is much wider at the base and more strongly narrowed to the 

 apex, more evenly rounded on the sides, hardly at all narrowed 

 to the base, &c.
