322 Mr. Bates on new species of 



IWchus Diemenensis. 



Sub-elongatus, depressus, thorace relative parvo, qiiadrato ; 

 subtus piceo-rufo, ventre rufo-testaceo ; capite thoraceque rufo- 

 castaneis, elytris nigro-piceis, palpis et pedibus flavis, antenuis 

 rufo-testaceis ; tborace quadrate, antice leviter rotundato, postice 

 pauUulum siuuato-angtistato, augulis posticis rectis, ibiqiie mar- 

 gine explanato-reflexo, margine basali iitrinqvie obliquo, foveis 

 basalibus magiiis, Irovibus : elytris oblougo-ovatis, humeros versus 

 baud angustatis, puuctulato-striatis, disco utrinque bipunctato. 

 Long. 5 mm. 



Soxitli or Central Tasmania (Simson). 



Similar in general shape to such species as Tr. palpalis ; but 

 the thorax is relatively smaller, and the explanated and reflexed 

 lateral margins, especially towards the hind angles, amply 

 distincruish it.

Elongato-oblougus, capite thoraceque supra viridi-a?neis, 

 elytris laste purpureis sericeo-nitentibus ; palpis ruiis, gracilibus, 

 articulis ultimis apice pauUo attenuatis ; capite ovato, oculis 

 baud prominulis : thorace quadrato, postice quam antice latiori, 

 angulis posticis acutis : elytris oblongis, fere parallelis, apice 

 valde obtuse rotuudatis, siqara sti'iatis, interstitiis pauUo convexis 

 tertio post medium 2-4 punctato : corpore subtus, antennis 

 pedibusque nigris, tibiis et tarsis rufescentibus. Long. 17-21 

 mm. $ ,^ . 



Distinguished from Ehahdotvs refie.rns (Chaud.) by the rich 

 uniform purjjle colour of the elytra ; similar in shape and in the 

 striated upper surface of the tarsi and the form of the palpi. 

 The eyes are encased behind by an orbit longer than themselves ; 

 the frontal furrows are broad, but not deeply incised. The 

 thorax is nearly as long as broad, narrowed to the front and 

 very gradually and slightly narrowed behind, with the hind 

 angles acute ; the lateral rims are thick and the margins reflexed 

 and explanated towards the hind angles ; the base is transversely 

 depressed. Head and thorax are glossy, brassy-green. The 

 elytra are very obtusely romided at the apex (most so in the $ ) 

 and the margin is but slightly sinuate before the apex ; the 

 striffi are moderately sharj^ly impressed. In certain lights the 

 rich purple colour changes into golden.
