Notes on Australian Coleoptera. 131 
anterior part, and growing narrower towards their extremity ; 
they have a lateral margin, and their axillary angles are 
carinated ; a feeble marginal row of points extends to this 
extremity. To the naked eye they appear smooth, but not 
brilliant, and with a lens very faint punctured striz are 
seen more visible on the sides ; anterior legs rather slender, 
with two strong teeth on their external side, surmounted by 
three other very minute ones. 
From Cooper’s Creek. In Dr. Howitt’s collection. 
This sort -is very nearly allied to Scaraphites Lucidus of 
Baron Chaudoir (“ Magas. de Zoologie”), but the elytra of 
Carbonarvus are more elongate, and not inflated in the 
middle. 
The group to which Mr. Macleay, jun., gives the name of 
Huryscaphus includes at this moment the following spe- 
cies :—Angulatus, Dilatatus, Minor, Bipunctatus, Water- 
houset, and Obesus (Macleay, jun.), Lucidus (Chaudoir), 
Howittu, Ajfinis, Hoper, and Carbonarvus, here described ; 
in all eleven species. Lucidus is erroneously stated by 
Chaudoir to be found near Melbourne; it is from the © 
Murray. Two specimens are in my collection from that 
locality. I have also obtained lately a specimen of Water- 
housei from Nickol Bay on the western coast of Australia. 
Mr. Waterhouse had found the one, which has been described 
by Mr. Macleay, in the centre of the continent. This mag- 
nificent insect bears a remarkable resemblance to the African 
Mamnticora. 
As I have already stated, Sc. Heros forms a passage 
between the two groups. It comes also near to Carenuwm 
Tuberculatum of Macleay, jun. , 
Scaraphites Hopet: length 144’; the smooth elytra of 
this insect, and the impression of the head without striole, 
only allows it to be taken for Lucidus or Mimutus, but in 
both of the latter the elytra are nearly circular ; while in 
Hoper they are oblong and rather prolongated behind ; the 
mandibulee are very acute ; the thorax rounded behind ; the 
humeral angles‘rounded, and not advanced ; the elytra when 
seen with a magnifying power show four very faint striz 
towards the sutura. The colour of the only specimen I have 
seen is of a light brown, probably from not being mature. 
It was found by Mr. Waterhouse in the centre of New 
Holland, and sent to me by that gentleman. 
Scaraphites Humeralis: length 15’ to 18’; black, gene- 
rally very brilliant ; head large, square, with two large
