The head and prothorax are coarsely and veiy rugosely sculp- 

 tured, the clypeal suture fairly defined, the prothorax with an 

 ill-defined impression across the middle, which widens into a vague 

 fovea on either side. The prothorax is equally long and wide, its 

 front margin nearly twice as wide as its base, its sides strongly 

 rounded, their edges (owing to the coarseness of the sculpture) 

 appearing crenulate. The eljtra are considerably dilated to 

 behind the middle ; their puncturation is very ill-defined, owing 

 to the roughness and irregular elevation of the interstices between 

 puncture and puncture in the rows which almost obliterate the 

 interstices between the 1st and 2nd, 3rd and 4th, &c., rows ; the 

 interstices between the 2nd and 3i'd, 4th and 5th, &c., rows are 

 well-defined and keel-like in front, but become fainter behind, that 

 betw^een the 4th and 5th being the strongest and most continuous; 

 the sutural line is well elevated. 



A very distinct species. The punctures in the rows on the 

 elytra are about the same size as in H. regularis, but are very 

 much less distinct, the spaces between the raised alternate 

 interstices appearing irregularly transversely ribbed (or from some 

 points of view almost tuberculate) rather than distinctly biseii- 

 ately punctulate. 



I have two specimens taken at Ararat, Victoria. 



OCHTHEBIUS AUSTRALIS, Sp.nOV. 



Sat latus ; nitidus ; antennis, palpis, pedibus et prothoracis 

 marginibus plus minus testaceis ; capite et prothorace fortiter 

 insequalibus vix perspicue punctulatis ; elytris fortiter sequaliter 

 punctulato-striatis. Long. 4-1 line, lat. ^-§ line. 



The clypeal suture is arched and very deep ; the portion of the 

 head behind it is sculptured in such fashion that there appear to 

 be (when looked at from directly in front) a raised space at each 

 corner and another in the centre, into which the surface is divided 

 by extremely deep channels. The prothorax is decidedly trans- 

 verse, ot equal width in front and behind, with srtongly explanate
