322 Mr. Bates on new species of 



Trechus Diemenensis. 



Siib-elongatus, depressiis, tliorace relative parvo, qnadrato ; 

 subtus piceo-rufo, ventro rufo-testaceo ; capita thoraceque rufo- 

 castaneis, elytris nigi-o-piceis, palpis et pedibus flavin, anteuiiis 

 rufo-testaceis ; thorace qnadrato, antice leviter rotundato, postice 

 paiilluhim sinuato-angustato, angulis posticis rectis, ibiqTie mar- 

 gine explanato-reflexo, margine basali utrinque obliquo, foveis 

 basalibTis maguis, lajvibus : elytris oblongo-ovatis, liumeros versus 

 hand aDgiistatis, pimctulato-striatis, disco utrinque bipuDCtato. 

 Long. 5 mm. 



South or Central Tasmania (Simson). 



Similar in general sliape to such species as Tr. pal pal is ; but 

 the thorax is relatively smaller, and the explauated and rellcxed 

 lateral margins, especially towards the hind angles, amply 

 distinguish it. 



Rhahdotus fiorichis. 



Elongato-oblongus, capite thoraceqixe supra viridi-fpneis, 

 elytris Itete purjiureis sericeo-nitentibus ; palpis rufis, gracilibus, 

 articulis ultimis apice paullo attenuatis ; capite ovato, oculis 

 baud prominulis : thorace quadrato, postice quam antice latiori, 

 angTilis posticis acutis : elytris oblongis, fere parallelis, apice 

 valde obtuse rotundatis, supra striatis, interstitiis paullo convexis 

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

 l^edibusque uigris, tibiis et tarsis rufescentibus. Long. 17-21 

 mm. ^ , 9 . 



Distinguished from Rhahdotvs rejlexus (Chaud.) by the rich 

 uniform purple 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 roimded at the apex (most so in the 9 ) 

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

 striaj ai-e moderately sharply impressed. In certain lights the 

 rich purj3le colour changes into golden.
