Notes on Australian Coleoptera. 133 
From Nickol Bay, on the north-west coast of New 
Holland. 
Note.—This insect by its oreat size can only be taken for 
Bacchus (which is unknown to me), but is very distinct by 
the form of the elytra, &c. 
Scaraphites Martini: length 14°; im general form 
it resembles very much Rotundipennis, but the thorax 
is broader and more rounded backwards, it has a 
broader lateral margin, and two strong impressions are 
seen on the posterior angles; the entire body is more 
smooth ; the colour is black, but not very brilliant ; elytra 
marked with very faint longitudinal striz ; on their margin 
extends a line of punctures, and behind it a series of seven or 
eight points much larger, and disposed on a longitudinal line 
beginning behind the humeral angle; on the posterior part 
of the elytra, and towards the middle of their breadth, are 
on each two punctiform impressions situated one below the 
other ; the anterior tibiz have three very strong teeth ; the 
tibise and tarsi covered with reddish hair. 
Found by Dr. Martin at Champion Bay. 
Note.—-Scaraphites MacLeayi, of Westwood, seems to me 
to be identical with Rotundipennis, of Dejean. Dr. Howitt has 
in his collection a specimen, given to him by Mr. Macleay, jun., 
which presents no differential characters. The one given by 
that entomologist himself, and based on the number of the 
points extending along the margin, is entirely without value. 
Rotundipennis presenting in some instances from eight to 
nineteen of these impressions ; much more, the numbers on 
the two sides of the elytra are often different, and so I find 
13 and 14, 8 and 9, 10 and 11, 14 and 10; and the typical 
specimen of MacLeayi, I have just mentioned, presents a 
similar case, having nine on one side and ten on the other. 
Intermedius of the same author seems, from his description, 
only to be founded on a similar character, and in that case 
ought also to be united with Rotundipennis ; the strong 
rugosities of the front part of the head, and the glossy appear- 
ance of the body being frequently observed in specimens of 
the common sort of Melbourne Rotundipennis. 
CARENUM. 
The following sorts appear different from all those described 
by Mr. MacLeay :— 
Carenum Brisbanensis: length 84’ ; black, not very bril- 
liant, having more or less a bronzed tinge; head having
