128 THE CARABIDAE OF TASMANIA, 



There were two specimens in the Simson Coll. without number. It is of 

 evidently larger size and narrower form than the species which I identify as P. 

 tasmanicus Cast.; both prothorax and elytra much less strongly rounded on sides; 

 anterior tarsi in male with four, not three, joints clothed beneath. It cannot be 

 P. subdepressus Guer. by basal angles of prothorax not rectangular — as said by 

 Putzeys . 



Promecoderus tasmanicus Casteluau. 



I attribute the name P. tasmanicus to a species given to me by the late Mr. 

 George Masters, ticketed "Tasmania" ; this specimen evidently represents the ^orm 

 with a wide prothorax referred to by Castelnau. The following description will 

 enable it to be recognised: — 



Nigro-virescent ; inflexed margins of elytra aeneous ; under surface with slight 

 viridescent reflections; anterior tarsi and palpi reddish. Elliptical-oval, rather 

 depressed. Head with suborbital cicatrix obsolete; eyes convex, prominent; post- 

 ocular part of orbits about one third length of eye. Prothorax broader than 

 long (2.7 X 3 mm.), cordiform-oval, strongly rounded on .sides, lightly transversely 

 depressed across base, declivous to basal angles, these obtuse. Elytra oval, 

 declivous to peduncle, rather strongly and roundly declivous to apex; disc lightly 

 striate; humeral angles marked. Anterior tarsi with three joints clothed beneath; 

 intermediate tarsi not clothed beneath. Length, 10.2, breadth, 3.7 mm. 



Specimens received from Mr. Lea ticketed "Mount Wellington" only differ 

 slightly, as under:-— c?, colour black; form narrower; both prothorax and elytra 

 less strongly rounded on sides. Length, 10.5; proth., 2.75 x 2.85; breadth. 3.6 

 mm. This is probably the narrow form referred to by Castelnau. P. tasmanicus 

 was not represented in the Simson Coll. 



Promecoderus plebius, sp. nov. 



Elliptical-oval, lightly convex; head with suborbital cicatrix obsolete; pro- 

 thorax with basal angles obtuse, but marked ; elytra oval, convex, striate on disc. 

 Black; legs piceous; tarsi and antennae piceous red. 



Head ordinary (2 mm. across eyes). Prothorax lightly convex, subcordate, 

 as long as broad (2.7 X 2.7 mm.), widest about anterior third, lightly rounded on 

 sides; sides narrowed in a gentle curve to base; basal area with a shallow, riither 

 rounded impression on each side; border narrow, well developed on each side of 

 i'pex and base; basal angles set low down, open but marked. Elytra oval (5.5 x 

 3.5 mm.) ; striae well marked on disc, obsolete on sides. Ventral segments 4 — 6 

 with a shallow impression on each side. (?. — Anterior tarsi with three joints 

 clothed beneath; intermediate tarsi not clothed beneath. Length, 8.5—10, 

 breadth. 3.3—3.8 mm. 



Hub. — Ben Lomond, 5000 feet (Siinsmi). Six specimens. 



I separate P. plebius from P. tasmanicus Cast., by shape more conNcx. espe- 

 cially of prothorax, which is less strongly rounded on sides, and with basal angles 

 set lower down, and more marked, though obtuse; even should it be regarded as a 

 variety of P. tasmanicus, .its separation under a varietal name seems advisable. 



Genus E u R Y L y c H N r .s. 

 EuRTLTCHNUS FEMORALis Sloane (1915). 



A black species apparently only differing from the genus Chiihiiis 

 (= Li/chnus Putzeys) by the presence of a mandibular seta. Prothorax sinuate 

 on sides before base, basal angles marked. Length. 14 mm.
