impunctate, curve of carina (seen sideways) continuous. Scu- 

 tellum semielliptic, raised in middle. EUjlra as wide as long 

 (16 mm.), widest behind middle, of the same width as prothorax 

 at base, sides gradually widened, widely rounded at apex, humeri 

 (seen from below) obtusely angulate; seen from above, the angle 

 formed by thickened raised border is rounded; foliate margins as 

 wide as those of prothorax at base, only slightly narrowed at 

 apex, gibbous at shoulders, horizontal at sides, more convex at 

 apex, extreme border very tliick and strongly reflexed, edge(seen 

 sideways) deeply concave and much wider than that of prothorax. 

 Disc convex, apparentl}' impunctate, separated from margins l>y 

 a row of round pustules continuous from behind humeral callus 

 almost to apex of costis; with strongly raised costa on eacli 

 elytron extending from base to apex of disc, diverging at base) 

 gradually converging on steep apical declivity, again a little 

 divergent near apex (3-5 mm. apart at base, 2 mm. distant at 

 apex), costje crenulate on sides, tlie suture slightly raised from 

 middle to apex, sulcate on each side, the depression widening 

 towards apex into a concavity between suture and costse, and 

 containing a single line of punctures rather widel}'^ separated. 

 Abdomen finely, not deeply punctured, underside of legs opaque 

 and slightly rough, tibiae coarsely punctured, sparsely clad witli 

 red recumbent hair and strongly bispinose. Prosternum convex

A single specimen, probably female, in tlie French Collection 

 of the National ^Museum, Melbourne. It is very distinct from 

 any described s[)ecies by its combination of large size and polished 

 -ebony-black colour. Though widely differing from H. coniiiilaris 

 Pasc , it is perhaps nearer that species than to others, but may 

 readily be distinguished by its more brilliant polish, by thespini. 

 form prothoracic carina, by its more ])arallel elytral costse, and 

 by its widely oval form. (//. consularis is obovate, widest at 

 shoulder, //. spinijei- widest behind tlie middle). Type in th«
