eljtris ovatis ad basin eraarginatis obsolete quinqueseriatim 

 tubereulatis sulcis lateralibus binis insequalibus. 

 This species is from South Australia, and I believe unique. 

 Like the last it has the lateral groove double, but the inter- 

 mediate costa in the present insect takes its rise from the upper 

 one at some distance from the humeral angle, and diverges 

 gradually towards the apex, while the upper groove is throughout 

 narrower than the lower. 



Since my last Paper on the Australian Scaritidce, a few species 

 have come under my notice, which I shall now describe. 



Caeendm parvulum. 

 Long. 5 1 lin. 



Nigrum subangustum, antennis gracilibus submoniliformibus, 

 pal pis labialibus apice triangularibus truncatis, thorace 

 subquadrato postice rotundato, elytris oblongo-ovatis thorace 

 angustioribus subopacis anguste violaceo-marginatis postice 

 bipunctatis, tibiis anticis extus tridentatis. 

 This species was found by Mr. Masters and myself last slim- 

 mer near Murrurundi, a town situated on the upper valley of the 

 Hunter, close to the Liverpool range. 



It is remarkable in several respects. It is the smallest Care- 

 num I have seen. The antennas most resemble those of the 

 C. Spencei group, the palpi are not securiform, and the anterior 

 tibiae are strongly tridentate. It would seem to form a kind of 

 link between the groups of which C. coruscum and G. Spencei 

 are the types. 



Caeenum foveipenne. 



Long. 7| lin. 



Nigrum, thorace subtransverso postice rotundato vix lobato 

 anguste viridi-marginato, elytris oblongis antice truncatis 

 postice rotundatis anguste viridi-marginatis quadri-seriatim 

 foveatis foveis rotundis aureo-viridibus, tibiis anticis extus 

 tridentatis dentibus validis subobtusis. 

 Mr. Odewahn of Gawler Town, South Australia, sent me this 

 species. It differs chiefly from C. Spencei in the colouring of
