The head is much hirger, especially much longer in front of the eyes ; 

 the mandibles and palpi being also longer. The elytra offer fewer 

 points of diffei'ence ; the interstices, however, maintain their convexity 

 to the apex. The antennae and palpi are reddish, and the legs dark 

 pitchy-red in all the examples I have seen. 



One example, from xlucliland, differs from the above description, 

 in being of a dull purplish-copper hue, inclining to seneous on the 

 Lead and thorax. 



PtEEOSTICHFS (TRICHOSTEEXrs) TEMIJKENSIS. 



Niger, supra fusco-cupreus, lateribiis interdum viridibiis ; pnlpis apice rujls : 

 tliorace transversim quadraio, postice vix sinnatim angtistato, anyuUs posticis paido 

 prominentibus ; elytris elongato-oblongis, pnnciato-striatis, interstitiis contexts, 3^°, 

 5'°, et '7''^^o paulo latioribus. Long. 83 lin. 



Very closely allied to Tr. 81/lviiis, and probably only a local form 

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

 tem?iJcensis, besides its more uniform and dusky -cupreous colour, 

 appears rather more elongate and parallel-sided, and shows, in some 

 examples, a conspicuous inequality in the width of the elytral inter- 

 stices. 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 Tr. antarcficus, the 

 angle being somewhat abruptly, and, to a less degree than in Tr. Sylcius, 

 turned outwards. The head and front margin of the thorax are formed 

 the same in both species. 



Temuka (C. M. Wakefield). 



Pteeostichtis (Trichostee^vus) Stltius. 



Supra viridi-ceiieus rel cupreo-cenetts, marginihus viridibus, nitidus, palpis apice 

 rujis : thorace transversim quadrafo, postice sinnatim angustato, angulis posticis 

 prominentibus, acutis : elytris oblongis, jmnctato-striniis, interstitiis convexis, cequali- 

 bits, tertio 3 vel A-, septimo pluri-pnnctato. Long. 9 lin. 



Agrees with the description of Feronia {Tr.) rectangula (Chaud.) 

 in every important respect, except in the hind angles of the thorax^ which, 

 instead of being " exacte rectis," are decidedly projecting. This char- 

 acter is constant in the six examples before me, and is corroborated by 

 the shining metallic colour of the whole upper surface, head included ; 

 Chaudoir giving as a speciality of Tr. rectanguJrt, " color paginse 

 superioris minus nitidus, elytrorum dorso fere nigricante." Specimens 

 agreeing with this description were taken by Mr. Wakefield, at Ean- 

 giroa, whereas all his examples of Tr. Sylvius came from Peel Forest.
