96 NOTES ON AUSTRALIAN COLEOPTERA, 



front distinctly margined all across, and with the striae of its 

 elytra strong and distinctly punctulate and their interstices 

 somewhat convex ; it is winged, and has rather prominent eyes. 



Besides this species, the Baron de Chaudoir places in Loxandrus 

 the following three : — Poecilus rufilahris. Cast., (from Queensland), 

 which is described as an iridescent insect, larger than iridescens 

 (long. 5 lines), with reddish-brown labrum and palpi, black legs 

 and brown tarsi, prothorax wider in front than behind (where it 

 is punctulate), and elytral striae strongly punctulate ; Poecilus 

 gagatinus, Cast., (from Tasmania), described as a small species 

 (long. 3| lines), entirely black ; and Poecilus atrouitens, Macl., 

 (from Queensland), which is briefly characterised as a little 

 smaller than subiridesceris, with the impressions on the head 

 feebler than in that species, the elytral interstices less convex, and 

 the surface almost devoid of iridescence. I have not seen any 

 species that I can identify with the three just named. 



Loxandrus l^vicollis, sp.nov. 



Alatus; sat elongato-ovalis; nitidus; niger, vix cyaneo-iridescens, 

 capite antice palpis antennis tarsisque rufescentibus ; oculis 

 sat fortiter prominulis ; prothorace haud punctulate, quam 

 longiori plus quam tertia parte latiori, tenuiter canaliculato, 

 utrinque ad basin sulco elongato longitudinali impresso, 

 antice late leviter emarginato, margine antico quam postico 

 paullo latiori, latitudine majori sat longe ante medium 

 posita, lateribus modice arcuatis, angulis posticis obtusis vix 

 rotundatis ; elytris punctulato-striatis, striis latera versus 

 minus profundis, stria abbreviata scutellari nulla, interstitiis 

 sat planis (3° ante medium punctura ornato).

Probably near L. rufilahris, Cast., but with the prothorax 

 entirely devoid of puncturation (except the two marginal 

 punctures). Compared with the species mentioned above, as 

 probably L. iridescens, Cast., this insect inter alia has a more 

 transverse prothorax, wider towards the front and with the
