148 NOTES ON AUSTRALIAN COLEOPTERA 



I am sorry that I caa suggest no structural characters for the 

 genus more reliable than those I have criticised, but after a pro- 

 tracted examination of a fairly numerous series of Ano'plognatlii 

 and Calloodes I can find not one structural character nor any com- 

 bination of structural characters that seem confined to and 

 invariable in either genus. Nevertheless the distinction of the 

 genera seems very desirable, for the species called Calloodes 

 certainly ditFer from all described Anoplognatld in being genuinely 

 metallic insects of pure brilliant colours (instead of being of some 

 shade of red or testaceous with more or less metallic gloss or 

 shimmer), of a wide DytisGus-\i]s.Q form somewhat (though not 

 very greatly) different from that of most if not all A7ioplognathi. 



Calloodes frenchi, sp.nov. 



Argenteo-viridis ; nitidissimus ; supra vix perspicue (capite 

 excepto) punctulatus ; elytris vix striatis ; prothorace medio 

 postice haud emarginato ; labro, mento, antennis, palpis, pedi- 

 busque testaceis ; corpora subtus (metasterni segmentorumque 

 ventralium lateribus exceptis) vix perspicue punctulato, parce 

 albido-piloso ; mesosterno fortiter producto ; pygidio sparsim 

 obsolete punctulato, apice leviter barbato.

Maris clypeo antice sat anguste producto sparsim punctulato, 

 supra obsolete bi-tuberculato ; coxis anticis externe ad apicem 

 bidentatis ; unguiculis simplicibus. 



Feminaj clypeo antice rotundato crebre punctulato ; coxis 

 anticis externe tridentatis ; unguiculis externis anticis bifidis. 



The clypeus in the male narrows forward for more than half its 

 length and then dilates very slightly to its apex which is much 

 narrower than its base, the front margin being gently rounded 

 (in C. Mastersi the clypeus of the male is almost parallel-sided in 

 its hinder two-thirds and then dilates to its apex which is quite as 

 wide as its base). 



The species closely resembles C. Mastersi, Macl., in colour, but 

 the beautiful silvery gloss that overspreads its green colour is even
