Much like L. lacrymosus, Cand., but much more nitid ; that 

 species is stated to be "opacus." I think I have identified L. 

 lacrymosus with tolerable certainty, although the description is 

 very defective, giving no information, e.g., as to the tarsal sulci. 

 Compared with that insect, the present one, besides being much 

 more nitid, is considerably smaller and narrower, witli more 

 elongate elytra, the carinate interstices of which (though growing 

 more carinate near the apex) are not tuberculate ; also the colour 

 is different, — the testaceous colour of the epipleurse and underside 

 of the prothoracic hind angles being conspicuous and apparently 

 constant ; the prothorax is less closely punctured and the tarsal 

 sulci of the prosternum are very much more sharply defined 

 (being not much less so than in L. caliginosus, GUier.) ; in both 

 species the tarsal sulci of the metasternum are distinctly indicated. 



South Australia ; not rare near Port Lincoln, under bark of 

 Eucalyptus.
