FURTHER NOTES ON AUSTRALIAN COLEOPTERA, 
The sinuous fovea on the front of the prothorax is very similar to 
that of the male, but is continuous to the centre line where it is 
rather sharply angulated, the part in front of the furrow resembling 
in form a hood turned back quite across the front of the prothorax, 
extending back half a line in the middle, its centre part but little 
triangularly produced. There are no smooth tubercles on the 
mentum, but it is strongly convex with its posterior two-thirds 
deeply and widely sulcate in the middle. The male was sent to 
me by Mr. Sloane, and was taken near Melbourne. The female 
is, I believe, from X. S. Wales. Occurs also near Adelaide. 
N.B. — A specimen (13| lines) in the South Australian 
Museum, which 1 consider a variety of this insect, may possibly 
prove to represent a closely allied s[>ecies ; it has the clypeus 
narrower and slightly emarginate in front, and the prothorax le.ss 
elevated behind with the lateral furrow continued from the sides 
all across the base (immediately within the margin as on the .sides). 
It has the same elongate parallel form as my tyi>e of Z>. major. 
Differs from Dejeani and AuMralis in the strongly dentate 
superior lobe of its maxillae, and in the slightly elevated smooth 
linear keel that runs do"«Ti the retuse ])oi-tion of the prothorax in 
the male. The size of the prothoracic excavation varies somewhat 
but in all the examples I have seen it is exceptionally large. Both 
sexes differ from the two just named and from tritviberculatus in 
their more parallel form, not dilated posteriorly ; the male differs 
from that of trittihercidatus by the presence of the keel on the 
prothoracic excavation, and the female differs from that of Aus- 
tralis by the sculpture of the head and clypeus, and by the 
different foveation of the prothorax.
