From that species, it differs in the more rounded sides of the 

 prothorax, and in the more obliterate granules, on both prothorax 

 and elytra. The sides of the prothoiax, tliougli appearing evenly 

 rounded from above, have the basal half distinctly ridyed, tliis 

 ridge being conspicuous only when viewed from the side. In 

 both species, the supraorbital crests differ considerably frcni the 

 usual form: instead of projecting more or less forwards from the 

 plane of the head, they project upwards and somewhat outwards, 

 the inner surfaces looking almost directly forwards. I have 

 not. however, thought it necessary to separate these two species 

 generically from Cubicorrhynchus. I have specimens of C. 

 Mnssoni from Walcha and Muswellbrook; these have been C(jm- 

 pared with specimens from the type-locality (Tamworth) in the 

 Macleay Museum. More recently, I have had an opportunity 

 of inspecting the tvpe in the l)ritish Museum, and am able to 

 confirm the identification. 



CUBICORKHYNCHUS AURICULATUS, n.sp. 



(J. Moderately small: elongate-ovate. Black; clothed with 

 muddv-brown squames, feebly emarginate with grey: teta^. 



Head convex, separated from rostrum by a transverse impres- 

 sion ; forehead with two, small granules; supraorbital crests 

 elongate, the apices directed upwards and outwaids, the inner 

 surfaces looking forwards as well as inwards. Rostrum with 

 upper surface slightly depressed; median line carinate, two 

 oblique, almost obsolete, internal ridges traceable; lateral margins 

 not raised, slightly depressed at base of crests, somewhat 

 divergent at base. Prothorax (2'5 x 3-5 mm.) feebly convex on 

 disc, with a marked, subapical, transverse impression; median 

 line impressed in basal half; lateral margins with a lather dis- 

 tinct notch about middle, this continued across disc as an in- 

 distinct impression, obtusely bidentate in front of notch, and 

 with a row of granules behind notch, lunning backwards and 

 inwards to latero-basal angle, which is marked and rectangular; 

 disc closely set with large, round granules, with two, rather 

 large, backwardly directed tuliercles overhanging the base, in 

 the middle; sides with rather coarse granules above, becoming
