This elegant species is nearly allied to Idiocephalus Roei before 
described, but differs in the marking on the thorax, and in the 
character of the marginal band of the elytra. It is a native of the 
east coast of New Holland, where it was taken by Mr. J. Horsley, 
a very observing Entomologist. Jdiocephalus Roei, its nearest ally, 
is a native of the western coast and Van Diemen’s Land, where 
it appears to be one of the commonest species ; so that the two, 
although so nearly allied, are inhabitants of parts of New Holland 
wide apart.
