BY THOMAS G. SLOANE. 221 



Length 14^, breadth 5 mm., prothorax 4J x 4|, elytra 8^ x 

 5 mm. 



This species seems to have a wide range ; there are specimens in 

 my collection, which I refer to it, from Melbourne, Sale, and 

 Tallarook, in Victoria ; and from Mulwala and Gunbower on the 

 Murray. It is a well known species, and very common in many 

 parts of Victoria. 



Promecoderus oblongus. 



p. oblongus, Casteln. I.e. p. 169 ; Putz. Revis. 1873, p. 334. 



This species is unknown to me. Only a single ^, de 

 Castelnau's type, has been reported. Judging from M. Putzeys' 

 very complete description, its slightly narrower form seems to 

 be all that separates it from P. hoivitti ; of which I believe 

 it will be found to be a variety. I cannot regard it as a 

 distinct species. The difference in colour — P. oblongus being " of 

 a metallic green" — I attach no weight to ; in P. lucidicollis the 

 colour varies from bronze to metallic green, and I believe the same 

 thing occurs in P. howitti. 



Promecoderus concolor. 



P. concolor, Germ. Linn. Ent. 1848, III. p. 168; Putz. Revis. 

 1873, p. 335; P. suturalis, Casteln. I.e. p. 170; Putz. Stett. 

 Ent. Zeit. 1868, p. 341 ; Revis. 1873, p. 335; P. lucidus, Putz. 

 Stett. Ent. Zeit. 1868, p. 339. 



(J. — Lsevigate ; of a shining bronzed back ; general form convex. 

 Head smooth, with the frontal impressions hardly marked ; the 

 clypeal suture distinct ; eyes prominent, inclosed behind ; the post- 

 ocular prominences not large. Prothorax rather cordate, a little 

 wider than long {i\ x 4| mm.), very convex, declivous behind, 

 constricted near the base ; the lateral margins very slightly sinuate 

 before the basal angles. Elytra very convex, smooth (9 x 5| mm.), 

 subparallel on the sides, not narrowed to the shoulders. Four 

 last ventral segments with a deep round foveiform impi'ession on 

 each side. The anterior tarsi with the three first joints dilatate 

 and spongiose below, the fourth smaller, the trochanters short 

 and rounded at the apex.
