in great numbers along the edge of permanent fresh water in the 

 Urana District in April, 1892. 



Tachys murrumbidgensis, n.sp. 



Elongate ; prothorax subcordate ; elytra depressed, finely 

 punctate-striate ; head, prothorax and interstices of elytra 

 sparsely and very minutely punctulate. 



Piceous black. Head smooth ; front strongly bi-impressed ; 

 the impressions parallel, extending to anterior margin of clypeus ; 

 the clypeus truncate, anterior part hollowed out between frontal 

 impressions ; eyes convex, not very prominent. Antennae monili- 

 form, strongly incrassate. Prothorax subcordate, lightly trans- 

 verse, widest before the middle, evidently narrower across base 

 than in front ; base very widely sub-lobate ; sides rounded, 

 shortly sinuate before the base ; basal angles acute and very 

 prominent ; lateral border narrow ; a transverse impression on 

 each side near basal angle defining basal part of prothorax ; 

 lateral fovese of base obsolete ; median line very lightly impressed. 

 Elytra a little wider than prothorax (1-2 x 0*75 mm.) ; sides 

 subparallel ; base emarginate ; shoulders prominent, round ; apex 

 evenly and widely rounded ; five finely punctulate lightly impressed 

 strife (exclusive of marginal stria) on each elytron, first, second, 

 and fifth reaching base, thiixl and fourth finer than others not 

 extending to base, first flexuous and approaching very near suture 

 towards base, fifth strongly impressed near base ; interstices flat, 

 fourth with two setigerous punctures uniting the third and fourth 

 strise (the anterior puncture placed at the beginning of the striae, 

 the other about half way between it and the apex), third with a 

 lightly impressed puncture on posterior declivity ; scutellar 

 stride wanting ; marginal channel strongly impressed with a few 

 punctures behind shoulders. 



Length 1-75, breadth 0-75 mm.

 near the edge of the water on a sand-bank in the INIurrumbidgee 

 at Narrandera, 16th March, 1893.)
