the edge, six strise strongly impressed on each elytron ; the 

 interstices rather convex. Three last ventral segments with a 

 well marked fovea on each side, from which a linear impression 

 extends inwards towards the middle of the segment. Anterior 

 thighs thickened in the middle ; anterior tarsi with four joints, 

 middle tarsi with two joints, spongiose below ; last joint of tarsi 

 narrow, a little flattened above, but not narrowed to the base. 

 Length 12, breadth 4^ mm.

The size is constant in the specimens I have seen ; it is allied to 

 P. olivaceus, from which it ditFers in its more metallic colour, its 

 much flatter shape, and lighter form.

I am unable to refer any of the forms I know to this species. 

 The following is a translation of M. Putzeys' note on it in his 

 "Revision" of 1873. 



Of a greenish black, slightly coppery on the elytra. Parts 

 of the mouth and anterior tarsi testaceous. The post-ocular 

 prominences two-thirds the size of the eyes. Prothorax cordate, 

 elongate, its greatest width is at the anterior third, whence it is 

 strongly narrowed to the base, where the sides are straightened 

 to form the posterior angles which are right angles. The elytra 

 are oval, narrower in front than behind, a little flat behind the 

 scutellum, marked with lightly punctate striae, the striae diminish 

 in depth towards the sides where the two last become even 

 hardly visible. The lateral fove^e of the abdomen are prolonged 

 internally by a stria parallel to the segments. 



Melbourne ; 3 specimens {^). 



M. Putzeys in his monograph of 1868 gives the size as 

 length 12, breadth 4|-, elytra 6|- mm. 



Guerin gives the locality as Tasmania ;* M. Putzeys is evi- 

 dently wrong in saying f the type came from the Swan River.
