seriatim punctulatis, striatis, interstitiis inter se sequalibus 



vix convexis, angulis humeralibus vix acutis ; tarsorum anti- 



corum sulcis sat angustis sat bene determinatis, posticorum 



subobsoletis. [Long. 2 (vix), lat. ? line. 



The smallest Australian Lacon yet described. Perhaps nearest 



to L. Victoria}, Cand., but smaller and narrower and with no 



difference between the punctures in the striae and interstices of 



the elytra, also the prothorax less closely and not at all rugulosely 



punctured. The dark antennae will distinguish this species from 



many of its allies. 



Victoria ; in the western districts. 



Lacon eucalypti, sp.nov. 



Minus latus ; minus nitidus ; sat convexus ; setis brevibus 

 cinereis sequaliter sat crebre vestitus; piceo-niger, prothoracis 

 angulis prosterno antice antennis pedibusque runs ; capite 

 prothoraceque crebre minus grosse punctulatis ; illo sub- 

 planato in medio impresso ; hoc quam longiori vix (postice 

 quam antice minus quam duplo) latiori, leviter canaliculato, 

 ad angulos anticos haud impresso, lateribus crenulatis autice 

 arcuatis a basi ultra medium fere parallelis, angulis posticis 

 sat acute rectis retrorsum vix productis intra marginem 

 lateralem vix perspicue carinatis ; elytris pone medium leviter 

 diktatis, quam prothorax paullo latioribus plus quam duplo 

 longioribus, punctulato-striatis, interstitiis planatis aequalibus 

 quam striae paullo minus crebre magis subtiliter punctulatis, 

 angulis humeralibus subobtusis nullo modo rotundatis ; 

 tarsorum anticorum sulcis angustis bene determinatis, inter- 

 mediorum sat distinctis. [-Long- 2J-2i, lat. -t-1 line. 



A small species nearly allied to several preceding, but distin- 

 guished by elongate elytra (which are evenly punctnlate-striate), 

 close puncturation of prothorax (which is not at all foveate within 

 the anterior angles), and strongly denned tarsal sulci, those of the 

 metasternum particularly being very well (though much less so 

 than in L. caliginosus and its allies) defined. 



S. Australia ; under bark of Eucalyptus near Port Lincoln.
