Several of tlie species described in tlie following pages, as will l)e 

 observed, are remarkable forms of the family Carahidce, and form an 

 interesting addition to our rapidly-growing knowledge of New Zealand 

 Coleoptera. 



PtEEOSTICHUS (TuiCnOSTEUNFs) DIFFOKMIPES, n. sp. 



Hlongato-ohlongiis, niger, supra rithro-cupreo tinctus, modice convexus ; capita 

 ovato, oculis modice prominentibus, collo hand crasso ; thorace quadrato, postice 

 modice sinuatim angustato, angulis posticis prominulis, suhacutis ; elytris elongato- 

 ovatis, apicem versus paulo sinuatis, supra punctulato-striatis, interstitiis cequalibus, 

 vix convexis, tertio et qiiinto props apicem bi-, septimo septem-punctatis, punctis longe 

 setiferis. Mas: femoribus intermediis stibtus late dentatis, tibiis intus emargi- 

 natis et apice paulo dilatatis. Long. lOJ lin., $ ? . 



Wellington, not uncommon in tbe same localities as P. (Trich.) 

 jilaniusculus (Mr. C. M. Wakefield). 



Eatlier more slender and less robust in form tban the typical 

 species of TricJiosternus ; tlie bead especially is narrower and not 

 thickened behind ; there is a moderate orbit behind the eyes. The 

 elytra are scarcely more convex than in T. Guerini (Chaud.), but the 

 stria) are simply and very finely punctulated, and the interstices smooth 

 and but slightly convex. The somewhat obscure red-coppery tinge is 

 diffused over the elytra, and on the thorax is most brilliant near the 

 hind angles. 



Pterostichus lobipes, n. sp. 



Eloyigato-oblongus, sub-depressus, ni.ger, serlceo-nilidus ; capita quadrato, orbitu 

 postice magis quam oculo prominenti, collo paulultwi constricto ; thorace quadrato,

 simis ; elytris valde elongatis, juxta basin transversim depressis, prope apicem 

 fortiter sinuatis, supra punctulato-striatis, interstitiis planis, Z^" , 5*0, et 7'°, quinque- 

 punctatis. Mas: tiliis intermediis apice extus lobato-productis. Long.2\ lin., $ .
