Species of Nev:i- Zealand Coleoptera. 351 



a slight flattening of tlie base inwardly ; the fine punctuation 

 at the base extends to the lateral margins, but the uiiddh', 

 though slightly uneven, is less evidently punctured. Elytra 

 convex, much broader than thorax, widest before the middle, 

 considerably narrowed behind; tlie shoulders, though rounded 

 and narrowed, are distinctly wider than the base of tlie 

 tiiorax ; their strise are rather shallow and finely punctured, 

 but become deeper, yet less evidently punctured, posteriorly; 

 the apical carina is well developed. The antennce reach 

 backwards to beyond the thorax, their third joint is rather 

 longer than the fourth, and the terminal is distinctly longer 

 than the tenth. There is a minute seta at each hind angle 

 of the thorax. 



When compared with T. la^vi'ventn's, no. 1800, the pos- 

 terior sinuosity at each side of the thorax is seen to be 

 deeper and the angles more projecting ; the hind body 

 broader, with more explanate lateral margins and wider 

 channels to within a very short distance from the very 

 slight incurvature near the apex, and that the ])Osterior plica 

 extends forwards to the hind thighs. The thoracic basal 

 impressions and punctuation also are quite different. 



Length nearly 2f lines ; breadth 1^ lines. 



Invercargill. 



One example from Mr. Alt'red Philpott. 



Tarastethus carhonarius^ sp. n. 



Compact, nitid, black ; legs rufous, tinged with piceous ; 

 tarsi, palj)i, and antennae fulvescent. 



Head (including the eyes) as broad as front of thorax ; 

 frontal impressions elongate and minutely punctured, with a 

 single seta near the back of each eye. Thorax nearly as 

 long as it; is broad ; base truncate, apex slightly incurve I ; 

 its sides finely margined and moderately rounded, rather 

 wider near the middle than elsewhere, moderately sinuate 

 behind, posterior angles a little prominent but not acute ; 

 its base resting on the elytra, the discoidal groove seemingly 

 finely punctate but not attaining the base or apex ; basal 

 fovege apparently absent, but represented by elongate feeble 

 in)j)ression3 only, its surface without distinct sculpture. 

 FAijtra oblong, witi) slightly refiexcd rims and somewhat 

 concave lateral channels, their sides only slightly curved ; 

 apex broadly rounded, the base finely margined and distinctly 

 wider than thorax ; the sutural two striae on each well 

 n)arked, quite deep behind and finely punctate ; third to 

 sixth distinct bchintl, mere series of line punctures on the
