before the basal angle. Elytra oval, a little wider than prothorax 

 (15-5 X 9-7 mm.), lightly convex, gently declivous to apex ; 

 apical curve obtuse, evenly rounded : striae shallow, finely 

 punctate ; striole at base of first interstice obsolete ; interstices 

 lightly costate, third, fifth and seventh stronger than second, 

 fourth and sixth, seventh strongest (decidedly costate), eighth 

 convex, ninth merged with margin, a row of lightly impressed 

 rather distantly placed punctures along its inner margin ; lateral 

 border reflexed, hardly so on apical curve ; marginal channel 

 narrow, equal ; basal border hardly arcuate on each side ; thii-d 

 interstice with two or three widely placed punctures on apical 

 half. Prosternum lightly longitudinally impressed between coxae ; 

 a single setigerous puncture on each side of base. Mesosternum 

 and metasternum la^vigate. Ventral segments smooth, third, 

 fourth and fifth with a setigerous puncture on each side of middle. 

 Posterior coxfe narrowly divided, metasternum and first ventral 

 segment meeting between them ; anterior tarsi with three basal 

 joints broadly dilatate and squamulose beneath. 



9. Not differing from ^, except in sexual characters. 



Length 28, breadth 9-7 mm. 



Hab. — Inverell, N.S.W. ; (sent by Mr. W. S. Duncan). 



A thoroughly distinct species. The colour alone would serve to 

 separate it from H. cyaneocinclum, Boisd., H. superbum, Casteln., 

 and //. obscuripmine, Macl., the three most nearly allied species 

 known to me. The interstices of the elytra are very different in 

 S. cyaneocinvtum, which has the third, fifth and seventh strongly 

 carinate, the fourth and sixth being obsolete. //. sioperbum 

 differs in the shape of the prothorax and elytra ; the sides of the 

 prothorax being sinuate behind, the elytra obovate, kc. If. 

 obscuripeniie has the elytra similarly shaped, but with all the 

 costse equal ; and has the prothorax more cordate, with the 

 posterior angles more marked though obtuse ; its colour is 

 entirely black. H. stibvirens, Chaud., (only known to me by 

 description) is a smaller species, and seems to differ decidedly in 

 colour, shape of prothorax, and the interstices of the elytra.
