134 Notes on Australian Coleoptera. 
between the eyes two arched grooves, united posteriorly by a 
curved and transverse impression, all the space between 
these lines being elevated; thorax rather square, a little 
broader than long, slightly marginated laterally, with the 
sides almost straight ; the posterior angles rounded ; the 
surface of the thorax presents transversal striole, and it is 
marked in the middle by a longitudinal sulcate, and at 
its anterior and posterior sides by two faint transversal 
impressions ; elytra oval, with the axillary angles rounded ; 
they are slightly marginated laterally, and present each two 
strong punctiform impressions on the middle of the breadth, 
one towards the fourth of the length, and the other at its three- 
fourths ; faint marks of longitudinal striz can be seen, with 
a magnifying power, on the surface ; anterior tibie with two 
strong teeth on their external side. 
Several specimens were found by Dr. Howitt near Bris- 
bane ; one was kindly placed by him in my collection. 
Carenum Ebermmwm : length 94’; of a rather dull black ; 
head with two longitudinal grooves curving transversely 
behind the eyes; thorax transversal, rounded behind, rather 
sinuous at the place of the posterior angles ; marginated all 
round, with a deep longitudinal sulcate in the middle, and 
two transverse impressions, one in front and the other 
behind ; elytra of an oval form, not broader than the thorax, 
having marks of very faint longitudinal puncturated lines, and 
presenting two rather deep punctiform impressions on each 
elytron, one at some distance behind the axillary angle and a 
little nearer the margin than the sutura, and the other a 
little past the two-thirds of the whole length ; anterior legs 
with two large teeth, surmounted by three others very 
small. 
I received one specimen from Mr. Odewahn, of South Aus- 
tralia, found near Gawler. 
Carenum Carbonarium: length 11’; of arather dull black ; 
head large, with two deep sulcates between the eyes, they 
run rather obliquely, and diverge in front towards the ante- 
rior angles of the head ; thorax broad, transverse, semilunar, 
rather sinuous behind, marginated, and presents a strong | 
longitudinal sulcate in its middle, and a rather faint trans- 
versal impression in front ; elytra not quite as broad as the 
thorax, marginated, of an oval form, with the axillary angles 
pretty well marked ; their surface is covered with very faint 
longitudinal lines too feeble to be called striz, and they 
present towards their posterior part a very feeble punctiform
