Notes on Australian Coleoptera. 137 
From Swan River. 
Carenum Odewahnis: length 103-13’; this insect has been 
taken by Mr. MacLeay, jun. (“Trans. Ent. Soc. of New South 
Wales ”) for Smaragdulwm, but it is easily distinguished by 
its much larger size, its elytra still more rounded at the 
humeral angles, and by the punctures of the marginal row of 
the elytra being much smaller, more regular and more 
numerous ; the punctiform impressions of the posterior part 
of the elytra are much less deeply marked; the teeth of the 
anterior tibiee are larger. 
Found by Mr. Odewahn near Gawler, in South Australia. 
Carenwm Coruscum (MacLeay, jun., “Trans. Ent. Soc. of 
New South Wales,” part ii, p. 141): specimens of this fine 
insect were brought by Mr. Hubert from the Paroo River, 
and are in the collection of Dr Howitt and in my own. 
Note.—- Carenum Marginatum, Germar (“ Linnee. Entom.”) 
from Adelaide, is probably C. Levigatum (MacLeay, jun.), the 
true Marginatum not being found in South Australia. 
Carenum Schomburgkia: length 84’; this insect is very 
nearly allied to Lwvigatum, and is only distinguished from 
it by its elytra being a little more elongated and covered 
with transverse striole. It may possibly be a simple 
variety. | 
South Australia. 
Carenwm Devastator : length 164’; of a rather brilliant 
black ; head large, smooth, with two longitudinal impres- 
sions between the eyes, diverging in front towards the ante- 
rior angles of the head ; on the space left between these im- 
pressions and the base of the mandibule are two punctiform 
impressions, one on each side; thorax broader than long, 
emarginated in front, with the anterior angles protuberant ; 
the sides, which are marginated, are almost parallel, rounded 
at the posterior angles, rather sinuous behind them; it is 
truncated and marginated behind; it has a longitudinal 
sulcate on its centre, a transverse arched impression in front, 
and two rounded impressions behind; on its surface are 
seen very faint transverse striole ; elytra long, oval, of the 
breadth of the thorax, marginated laterally, truncated at the 
base ; the axillary angles are well marginated, and rather 
acute, their surface is smooth, and they present each two 
punctiform impressions, one behind the axillary angle and 
the other backwards ; the general form of the body is elon- 
gated, and the aspect is that of a Scarites. 
From Swan River.
