148 THE CARABIDAE OF TA.S3IAXIA. 



tangular; elytra oval, strongly striate, seventh and eighth striae weak, interstices 

 1 — 5 convex, third interstice 3-punctate beside third stria. a]>ical striole in line 

 with fifth stria. Black, legs and antennae reddish. 



Head large (0.8 mm. across eyes), obliquely narrowed l)ehiiid eyes (continu- 

 ously with slope of eyes); vertex convex; frontal sulci curved, decidedly diver- 

 gent and defining orbits posteriorly; eyes prominent; mandibles prominent; 

 labrum emarginate. Prothorax broader than long (0.85 ^ 1.15 mm.); apex 

 lightly emarginate; anterit)r angles obtuse, a little prominent; sides lightly 

 rounded; base truncate, sloping lightly forward at each side; Ijasal angles, sulrect- 

 angiilar. summit obtuse; border strongly reflexed, not wide, liardly wider towards 

 base; lateral channel curving round at basal angles and uniting with bottom of 

 basal impressions, these deep; median line strongly impressed. Elytra oval (2.5 

 X 1.6 mm.), convex; humeral angles rounded off, not marked; interstices (i — 8 

 uniting to form a narrow carina at apex, this carina defined on inner side by a 

 strongly impressed apical striole; posterior puncture of third interstice level with 

 anterior end of apical striole. Leng'th. 4. breadth, l.fi nun. 



Hah. — Great Lake. Unique in the Simson Coll. 



A very distinct species, not nearly allieil to any other yet found in Tasnmnia. 

 If the sides of the prothorax are viewed from straight above they ajijH'ar to be 

 lightly sinuate before the basal angles; but. if looked at from the o|)posite side 

 across the segment, this sinuosity (which is caused by a sliyht lioi-i/.ontal curve 

 of the border) disappears.

Trechcs loxginotatus, sp. nov. 



Oval, robust; head large, arcuately bisulcate; prothorax cordate, narrower 

 across base than apex, sides sinuate posteriorly, basal angles acute; elytra widely 

 oval, weakly striate, third interstice 3-punctate, posterior puncture above apical 

 declivity. Black; elytra with a humeral lunule, inflexed margin, apex, a .small 

 ante-apical spot, and apical part of first interstice lurid-testaceous; antennae in- 

 fuseate, base reddish ; legs testaceous, tibiae and tarsi brown. 



Head finely shagreened. large (0.7 mm. across eyes), strongly narrowed be- 

 hind eyes) ; vertex convex; frontal sulci curved, strongly divergent posteriorly; 

 eyes convex, rather small, a little prominent; post-ocular part of orbits about as 

 long as eyes, curving continuously with eyes to head. Protliorax broader tlian 

 long (0.7 X 1 mm.) ; apex liglitly emarginate; anterior angles obtuse, bordered, 

 a little prominent; sides lightly rounded anteriorly, shortly sinuate before base; 

 basal angles acute; base truncate; border narrow, refie.ved, very little wider at 

 Itasal angles; lateral channel curving round at basal angles to form bottom of 

 basal impressions, these well marked; median line well marked (m disc. Elytra 

 oval (2 X 1.4 inin.l subconvex; base wide; basal curve .short; diseal striae lightly 

 impressed, first only entire; striae 6 — 8 obsolescent; recurved apical striole nanow.

With T. hrerinniatus SI., this species forms a distinct group. Cniiqiaring 

 these two species with T. monolobus Putz., and T. scapularis Putz., from Cliili, 

 species which also have post-humeral maculae, it is at once seen that there is iittle 

 affinity towards the riiilian species. The Tasmanian species have the liciul uar-
