Chatsworth, Illawarra, New South Wales ; Mountains near

Although this species is closely allied to Ipsaphes mosrosus, Pasc, 

 it may readily be distinguished from it by the colour of its elytra, 

 its narrower head and the larger size of the thoracic teeth. The 

 joints of the antennae appear to be proportionately larger, 

 especially towards the apex, and the scutelhnu is pointed behind 

 and not ronnded as in that species. 



I have had a specimen of this insect in my possession for some 

 time, bearing the manuscript name " bicoJor" in the handwriting 

 of the late Dr. Howitt, of Melbourne.

All the specimens of Platisus, some thirty in number, which I 

 have examined, appear to belong to this species. In some of 

 them the prothorax is decidedly narrower than in others.
