Ilah. W. Australia : Perth, Israel Bay. 



Specimens have existed in tlie British Museum for over 

 seventy years, and others have recently been taken at Perth 

 by Mr. G. E. Bryant. The peculiar lustreless uj)pcr surface, 

 ot the pronotum especially, distinguishes the species from all 

 others known to me. It is of an intense coal-black colour, 

 with a broad pronotum entirely devoid of punctures, and tiie 

 elytra are rather evenly and uniformly punctured in rows. 

 Tlie shape of the thoracic cavity is also peculiar, being longi- 

 tudinal, with an anterior dilatation in the male which gives 

 it a triangular outline.

 B reiver). 



A single male specimen has been in the British Museum 

 since 18/0. 



The species of Novapiis are remarkably alike in general 

 appearance, especially the males, but the examination of the 

 pygidium shows differences of sculpture and cljthing, which 

 seem to be sufficient for the separation of most of them. 

 The present species is the only one known in which that part 

 of the body is closely rugose, the others having it punctured 

 or smooth, often with a close fringe of hair at the base. 

 Although Blackburn has not mentioned the pygilium of 

 N. striatcqyunctulatus, which appears to resemble the new 

 species, his type is a much larger insect, and, as its pro- 

 thorax is less excavated, the difference ot size is evidently 

 not due merely to variation.
