Insectorum," places them in the latter family. I do not 

 concur without hesitation in this arrangement, but as the 

 classification of the "Genera Insectorum" will no doubt be 

 widely followed, I accept it. 



This group, like the Cebrionidce, is easily distinguished 

 from the true Elateridca by tibiae dilated and of triangular 

 form (of the fossorial type) and furnished with strong deve- 

 lopment of spines. It has not hitherto been reported as 

 occurring in Australia. It is represented in my collection 

 by two specimens, for which it is necessary to form two new 

 genera. 



NULLARBORICA, gen. nov. 



Frons declivis ; labrum fortiter transversum ; antennae sat 

 fortiter serratse, articulis 3° quam 2 11S multo longiori, 

 11° subappendiculato; prothorax a basi ad apicem angus- 

 tatus, ad latera marginatus, margine (superne viso) sat 

 continuo; presternum antice truncatum, suturis sinuatis 

 antice clausis postice nonnihil duplicates ; tarsi subtus 

 haud laminati ; coxae intermediae haud plane contiguae ;. 

 sulcus mesosternalis manifestus. 



The characters cited above in combination distinguish, 

 this genus from those described in the "Genera Insectorum. " 

 It bears much superficial resemblance to Antoligostethus, but 

 differs by its head obliquely declivous, the margins of its 

 prothorax not bent down in the front part in such fashion as 

 to be invisible from above, by the front of its prosternum 

 more abruptly truncate and by its intermediate coxae not in 

 contact with each other but separated by a quite visible 

 mesosternal cavity. 



N. concinna, sp. nov. Rufo-brunnea ; modice nitida; supra 

 pilis brevibus suberectis sat dense vestita ; antennis ultra 

 prothoracis basin elongatis ; capite crebre fortiter punctu- 

 fato; prothorace quam trans basin latiori fere quarta parte 

 breviori, supra sat sequaliter fere ut caput punctulato, 

 antice modice angustato, margine antico bisinuato, lateri- 

 bus fere rectis vix sinuatis, angulis posticis haud divari- 

 catis intra marginem haud carinatis ; scutello ovali ; 

 elytris quam prothorax plus quam triplo longioribus, sat 

 fortiter striatis, interstitiis leviter convexis crebre minus 

 subtiliter punctulatis, apice vix acuto fere rotundato ; 

 prosterno episternisque crebre subgrosse punctulatis ; 

 processu prosternali supra planato, postice abrupte 

 declivi ; coxis intermediis subcontiguis ; sulco mesoster- 

 nali manifesto; coxis posticis intus gradatim sat for- 

 titer (sed supra trochanteres paullo magis fortiter) 

 dilatatis; abdomine sat crebre sat fortiter punctulato ;
