Eortnum, of Adelaide, leaves scarcely a doubt tliat it should be 

 ''Morialta." 



In Masters' catalogue this insect is attributed to N.S. "Wales 

 only. 



&ERMARICA, gen. nov, [Trachydse]. 

 ApJianistico affinis, sed antennarum clava 7-articulata, capite 

 vix canaliculato, tarsis longioribus, horum articulo quarto 

 valde dilatato. 



The insect for which I propose this generic name has quite 

 the appearance of the European Aphanisticus pusillus, Herbst., 

 but in spite of this striking resemblance cannot be associated 

 with it, on account of structural differences in the head, an- 

 tennae, and tarsi. The head is hardly channelled; the antennae 

 are not longer than the width of the head, and are very stout, 

 the apical seven joints strongly produced inward, so that these 

 seven joints together form an abrupt club (reminding one of 

 the antennal club of Syndesus in the Lucanidcd) scarcely more 

 than twice as long as it is wide, and longer than the four joints 

 that precede it together. The tarsi are decidedly, though not 

 very much, longer than those of Aphanisticus, their fourth 

 joint much dilated, the claws very small. I do not know the 

 genus Paracephala, Thoms., but its name cannot stand, having 

 been previously used for a genus of Fhytophaga. If Mr. 

 Masters is right in attributing to it Agrilus pistacinus, Hope, 

 the insect I am describing has nothing to do with it. 



G. casuarincd, sp. no v. Elongata, nigro-aenea ; glabra ; pro- 

 thorace leviter transverse, lateribus baud explanatis ; 

 elytris leviter sparsim punctulatis. Long. 1\ 1., lat. -f 1. 



The whole upper surface is dulled somewhat by a system of 

 very fine close puncturation ; over this are sprinkled larger and 

 very faint punctures, which are sparse on the head, much more 

 so on the prothorax, numerous on the anterior half of the 

 elytra, and obsolete behind. The prothorax is about half again 

 as wide at the base as down the middle it is long, and has its 

 sides gently rounded to the front, which is about three quarters 

 of the width of the base; a transverse impression runs imme- 

 diately in front of the base, which is bisinuate. The elytra are 

 about four times as long as, and not wider than, the prothorax ; 

 they are sub-parallel in their anterior two-thirds, and then 

 contracted to the apex. They have no trace of sculpture other 

 than that described above. The under surface is evenly and 

 very finely and closely punctured. 



A few specimens were taken by me near Port Lincoln by 

 beating Gasiiarina. There are also two examples, unticketed, 

 in the S. Australian Museum.
