larger and at sparser one-third from apex than elsewhere. Elytra 

 rather short and wide, with rows of large, but not very deep 

 punctures; suture with numerous rather small depressed granules; 

 third interstice with a row of small round tubercles; fifth and seventh 

 with somewhat similar but smaller and less regular tubercles. 

 Apical segment of abdomen with an excavation extending almost 

 across its entire width, but suddenly deepened in middle; its anterior 

 margin with a small tubercle on each side. Length (excluding 

 rostrum) 14-15 mill. 



$. Differs in having the elytra wider across middle, and narrower 

 at apex; and the apical segment of abdomen longer and without a 

 large excavation. 



Hab. : N. S. Wales : Jenolan (J.-G. Wiburd), Blackheath (Macleay 

 Museum). 



A short robust species resembling rugosus, but shorter, with the 

 rostrum and elytral tubercles and abdominal excavation of male 

 different, the prothoracic granules slightly smaller. Rudis, to which 

 perhaps it is somewhat closer, also has the abdominal excavation of 

 the male diflerent. 



The elevated parts between the rostral scrobes, when viewed 

 from behind, form a perfect M, except that the inner arms do not 

 quite meet. The prothorax of several specimens appears to have a 

 feeble median line, owing to the comparative sparseness of granules 

 along the middle. The sides of the elytra are without tubercles, but 

 owing to the undulations caused by the punctures, each of these 

 appears to be surrounded by four or live very obtuse ones. On one 

 specimen there is a depressed tubercle on the second interstice on 

 the left side and two on the right, and three on the fourth interstice 

 on the left side and two on the right; but on tour others the second 

 and fourth interstices are without tubercles.

(2^. Black. With fairly numerous but small and very indistinct 

 sooty scales. With depressed black setse, becoming shorter and 

 paler and forming feeble spots along middle of abdomen. 



Rostrum with a deep horse-shoe shaped impression, the hind end 

 of which marks its junction with head; median excavation wide 

 and shallow; a ridge on each side with its outer wall fairly abrupt, 

 but inner gradually sloping into the median excavation. I'rothorax 

 moderately transverse, sides strongly rounded ; witli dense, fairly 

 large and somewhat depressed granules, approaching the size of 

 small tubercles near, but not at, apex. Elytra at base distinctly
