riiwer. moi-o (lee])ly bisuleate, eyes smaller and less proininent ; elytra more striate, 

 third pimeture of the third interstice above the apical declivity. In T. longino- 

 tatits the elytra have, on each, a lurid testaceous humeral lunule extending- from 

 the sixth interstice at the humeral angle and curving inwards liehind the anlerior 

 puncture of third interstice on to the fourth interstice, and there is au indistinct 

 macula of a duller colour on the apical declivity beside the recurved striole. 



TrECIIUS BREVINOTATU.S, sp. nOV. 



Oval; head large, arcuately bisuleate; prothorax cordate, hardly narrower at 

 base than apex, sides roundly narrowed to base, basal angles obtuse; elytra oval, 

 lightly striate, interstices depressed, third 3-punctate beside third stria, posterior 

 puncture above apical declivity. Pieeous-black ; vertex, sides and base of pro- 

 thorax (narrowly), border, inflexed margin, and tirst intei-stiee (especially behind 

 niiddlel reddish; apex (rather widely), and a rotundate humeral spot outside fifth 

 interstice lurid-testaceous; antennae infuscate, l)ase reddish; legs testaceous; tiliiae 

 and tarsi brownish. 



Head largi' (0.7 across eyes) ; vertex convex; frontal sulci deep, lightly diver- 

 gent posteriorly; post-ocular part of orbits small (not half size of eye), strongly 

 raised from head; eyes large, convex. Prothorax broader than long (0.7 X 

 1 mm.) ; apex truncate; angles obtuse, not prominent; sides lightly rounded; base 

 truncate; angles obtuse; lateral border narrow anteriorly, a little wider near base ; 

 lateral channel wide; lateral basal impressions well marked; median line distinct. 

 Elvira oval (2.2 -^ 1.5 ram.), convex (a little depressed near suture) : base wide; 

 striae 1 — 5 lightly impressed, 6 — 8 obsolescent. Length. 3.7, breadth. 1.5 mm. 



Hah. — Great Lake (Simson). Unique. 



Allied to T. loucjinotatus SI., from which it differs decidedly b\' eyes larger 

 and more convex, orbits less developed behind eyes, frontal sulci less divergent 

 jiosteriorly; iirothoi'ax with anterior angles less prominent, sides not sinuate 

 before basal angles, these obtuse; elytra witli shoulders more rounded off, post- 

 humeral maculae shorter, not reaching backwards as far as anterior puncture of 

 third interstice. The apical decli^'ity is of a rather lurid-testaceous colour, bul the 

 dark ground coloui' extends well down the declivity. 



Trechus xitens Putzeys. 



T have identified T. nitens Putz., from the description. Length, 3 mm. 



Hab. — Mount Wellington (Lea); "in roots of grass at summit.'' Mr. Lea 

 sent it to me, ticketed T. tasmaniae Blackb., which I believe to be an allied, bvtt 

 distinct, species. 



Trechus blackburxi, sn. nov. 



Oval; head large; prothorax cordate; elytra rotundate-oval, convex. Black; 

 inflexed margins of elytra, legs, mouth-parts, and antennae reddisli. 



Head ordinary (0.8 mm. across eyes). Prothorax cordate (0.8 x 1 mm.), 

 widest before middle; base and apex of about equal width; sides rounded, oblique- 

 ly narrowed to base; basal angles marked, obtuse; border strongly reflexed at 

 basal angles; lateral basal impressions foveiform. Elytra widely oval (2.3 x 1.7 

 mm.), convex; base rotundate; disc striate; striae faint towards sides; apical 

 striole in line with fifth stria (but not quite uniting with it) ; third inteistiee 

 3-punctate beside third stria, posterior puncture above apical declivity; interstices 

 f) — 8 uniting to form a ridge at apex. Length, 3.8, breadth, 1.7 mm. 



Hah. — Cradle Mountain (Carter and Lea).
