204 REVISIONAL NOTES OX AUSTRALIAN' CARAHIDAE,. 



that the prothorax is impunctate, l)ut this is an eiTor; an examination ol' the 

 ootvpe in ray cullectinn under a mieroscope disc-loses a faint and sparse punc- 

 turation. 



Tachys wilsonj, n.sp. 



Robust, convex. Prothorax transverse, subcordate; elytra convex, smooth, 

 sutural stria strongly impressed, titth present on basal third, apical striole 

 short, wide, near margin. Head brown; prothorax and elytra ferruginous, nitid; 

 legs and antennae testaceous. 



Head stout; frontal sulci parallel, short, not deep. Pi'othorax rounded on 

 sides, shortly sinuate before posterior angles; ba.se truncate above peduncle, 

 slopiflg lightly obliquely forward on eaoh side. Elytra oval; eighth stria obsolete; 

 a foveiforni impression a little inward from apical striole; three fixed punctures 

 present, anterior at position of fourth interstice, posterior high up on apical 

 declivity; second stria obsolescent, faintly perceptible between discal punctures; 

 a puncture at anterior extremity of apical striole. Length, 2; breadth, 0.9 mm. 



Hah. — t^ueensland. A specimen was kindly given to me by Mr. F. E. 

 Wilson, who found it at Hrisbane in October. 



A very distinct species, more allied to T. leai SI., than to any other species 

 known to me, but differing decidedly by colour; smaller size; head shorter, 

 frontal sulci shorter and more parallel, eyes less prominent; elytra more oval 

 and much more convex, discal striae (excepting first and basal part of fifth) 

 almost completely lost. Comparing it with T. amtralicus SI., the presence of the 

 strongly impressed basal part of the fifth stria at once distinguishes it. The 

 head and prothorax liave some microscopic punctures, wliicli are stronger on 

 the head. 



Tachys ectromioioes Sloane (ISOG). 



Hab.— N.S. Wales: Richmond River (Lea), Blue Mountains (Carter); Vic- 

 toria; Mell)ourne (Fischer); W. Australia: Donnybrook (Lea). 



This seems to be a rare species, I know nothing about its habits. 



Tachys atriuermis, n.sp. 



Oval, robust, convex. Head convex, frontal furrows well marked, clypeus 

 with latei-al punctures foveiform; prothorax transverse, evidently narrowed to 

 base, lateral basal impressions deep, basal angles rectangular; elytra oval, bis- 

 triate on each side of suture, eighth stria entire, first interstice raised, ninth 

 interstice depressed, disc bipunctate, apical striole well developed, short. Black, 

 legs ferruginous; antennae infuscate with base ferruginous; palpi infuscate. 



Head wide, convex; frontal impressions elongate, lightly divergent pos- 

 teriorly, not extending on to clypeus; space between frontal impression and eye 

 on each side narrow, raised, bearing a foveiform setigerous jjuncture posteriorly; 

 antennae stout, second joint riitlier shorter than tliird. Prothorax widest a 

 little before middle, a little wider at base tluin apex; sides lightly roundly am- 

 pliate before middle, obliquely narrowed to base; lateral border rellexed; space 

 between lateral basal fovea and margin raised into ii sliort carina; a dec]) trans- 

 verse linear basal impression extending inwards from each lateral fovea, but 

 not meeting in middle. Elytra oval; two or three crenulate striae on disc, first 

 entire, second hardly perceptible on apical third, but developed into a shallow 

 oblong fovea between aiiical striole and suture; a well marked basal fovea on 

 each side of scutellum; two fine punctures on disc outside second stria, a dis-
