sides. Club not very large, about the width, of clypeus. 

 Prothorax moderately transverse, latero-apical incurvature 

 slight, latero-basal very feeble ; median sinus moderately deep, 

 about one-fifth the width of base, the lateral ones shallower 

 and somewhat oblique ; punctures dense, but not very large, 

 in places transversely confluent. Scutellum with larger but 

 sparser punctures than on prothorax. Elytra short, post- 

 humeral incurvature moderate, with a distinct but rather 

 narrow and feebly-elevated ridge one-third from suture, and 

 disappearing posteriorly ; with dense, coarse, and irregular 

 punctures, becoming transversely confluent towards sides. 

 Pygidium concentrically strigose, with a fovea on each 

 side. Mesosternal process short and obtuse. Abdomen some- 

 what flattened along middle. Front tibicz obtusely bidentate, 

 with a short stout spur; middle pair bidentate and unequally 

 bispinose at apex, towards base with a strong semidouble 

 tooth ; hind pair with a triangular tooth and a truncated one, 

 and with two long acute unequal spurs at apex, with an 

 oblique dentiform ridge at middle, and a less-distinct one 

 towards base. Length, 17 mm. 



Hab. — North-western Australia: Shark Bay. Type in 

 National Museum, Melbourne, from C. French. 



Allied to the preceding species, but more robust, pro- 

 thorax entirely black, front tibiae differently armed, spurs of 

 hind tibiae simple, and club much smaller, etc.

9 . Black with a slight bronzy or bronzy-green gloss, 

 inner half of two apical- joints of club bright-red. Under - 

 surface and legs with rather short brownish or greyish hairs, 

 becoming still shorter on pygidium. 



Head rather strongly convex in middle, with deep punc- 

 tures of irregular size and distribution. Clypeus with rather 

 strongly turned-up margins, apex widely rounded, sides de- 

 creasing in width to base ; punctures larger but shallower 

 than on head, suture traceable only at sides. Club much 

 shorter than width of clypeus. Prothorax feebly transverse, 

 sides strongly rounded towards apex, apex distinctly incurved 

 to middle ; median sinus shallow, about one-fifth the width 

 of base, the lateral one somewhat oblique and very feebly in- 

 curved ; with dense punctures of moderate size, becoming 

 coarser and transversely confluent on sides, and almost absent 

 from a narrow median line. Scutellum with two irregular 

 series of punctures. Elytra moderately long ; posthumeral in- 

 curvature feeble ; with very dense, coarse, and irregular punc- 

 tures, but leaving five almost impunctate ridges on each
