518 NOTES ON AUSTRALIAN COLEOPTERA, 



less developed than those of Dascillus and the apical spines of its 

 tibice (though not large) are quite well-defined. The apical joint 

 of its maxillary palpi is shorter and considerably less stout than 

 the preceding joint. It departs from Helodes also in its glabrous 

 upper surface ; I do not think the example before me is abraded. 

 The small diamond-shaped piece behind the middle of the 

 metasternum and between the bases of the hind coxae (which is 

 noticeable in most if not all of the Dascillidcv, and which I take 

 to be the scutum of the metathorax) is extremely conspicuous in 

 this species. 



Victoria ; Alpine district. 



Helodes cinctus, sp.nov. 



Sat late oblongus ; sat convexus ; sat nitidus ; crebre breviter 



fulvo-sericeo-pubescens; rufus, prothorace posticeet elytrorum 



singulorum disco toto infuscatis ; capite prothoraceque crebre 



subtiliter punctulatis ; hoc quam longiori plus quam duplo 



latiori, angulis posticis subrectis ; elytris leviter distincte 



3-costatis, sat fortiter sat crebre punctulatis ; antennis quam 



corporis dimidium manifeste brevioribus, articulis 2° 3° que 



conjunctis quam 4 US brevioribus. [Long. 3, lat. 1± lines. 



Structurally very similar to the preceding but with the apical 



spines of the tibise less developed though quite distinct. In the 



example before me the infuscation of each elytron leaves only all 



the margins narrowly red. The puncturation of the elytra is 



about as strong but not nearly so close as in the European H. 



minutus, Linn. ; it becomes finer and feebler towards the apex ; 



there are no transverse wrinkles.

Helodes olliffi, sp.nov. 



Oblongus ; sat parallelus ; depressus ; pubescens ; obscure 

 fuscus, antennarum basi tibiis tarsisque paullo dilutioribus ; 

 capite subtiliter, prothorace subtilissime, crebre punctulatis ; 

 hoc fere semicirculari basi bisinuato ; elytris crebre minus 

 subtiliter punctulatis, lineis 3 elevatis obsoletis instructis ;
