Wellington ; not uncommon in the same localities as P. (Trich.) 

 planiusculus (C. M. Wakefield). 



Rather more slender and less robust in form than the typical species 

 of Trichosternus ; the head 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 striae are 

 simply and very finely punctated, 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. 



NOTE. I received two examples of this species some time ago from 

 Mr. J. Buchanan, of Wellington, and described it some months ago, 

 but Mr. Bates' description having been published, his name must have 

 precedence. The T. aucklandicus was described, and the paper read 

 at the Anckland Institute a year ago, so though Mr. Bates has recently 

 re-described it, it appears as I originally intended.

71. T. (PterOSticlms) temukensiS, Bates; Entom. Mon. 

 Mag., July, 1878, p. 26. Niger, supra fusco-cupreus, lateribus interdum 

 viridibus ; palpis apice rufis ; thorace transversim quadrato, postice vix 

 sinuatim angustato, angulis posticis paulo prominentbus; elytra elongato- 

 oblongis, punctato-striatis, interstitiis convexis, 3 io , 5 to , et 7 mo paulo 

 latioribus.

Very closely allied to T. sylvius, and probably only a local form of 

 the same. Comparing half-a-dozen specimens of each species, T. temu- 

 kensis, besides its more uniform and dusky-cupreous colour, appears rather 

 more elongate and parallel-sided, and shows, in some examples, a con- 

 spicuous inequality in the width of the elytral interstices. But the most 

 important and constant structural feature is in the curvature of the sides of 

 the thorax ; this, instead of forming a rather deep sinuation posteriorly 

 between the middle and the tip of the hind angles, continues nearly to the 

 base, as in T. antarcticus, the angle being somewhat abruptly, and, to a 

 less degree than in T. sylvius, turned outwards. The head and front 

 margin of the thorax are formed the same in both species.
