just before the angles of the base ; the anterior angles are obtuse 

 and very lightly marked ; the posterior angles are well marked 

 and almost right angles. The surface is convex on the sides 

 and a little flattened to the middle ; the median line is deep ; it 

 does not extend beyond either of the transverse impressions, both 

 of which are very distinct. The elytra are oval ; the shoulders 

 are not at all marked ; the border is prolonged to the apex ; the 

 surface is a little flattened only on the first half to about the 

 third stria ; the strife are wide, shallow, lightly punctate ; only 

 the first is entire ; the three following are marked at the base, 

 but do not reach the apex ; the fifth and sixth are only distinct 

 in the middle. The episternaof the metathorax are a little longer 

 than broad. The segments 2-6 of the abdomen have on each side 

 a very deep round fovea ; the last segment is transversely strio- 

 late, particularly in the 9. The anterior and middle tarsi 

 of the (J are very narrow, lightly spongiose only in the middle ; 

 the last joint is club-shaped and hardly flattened.

There are specimens (2) of this species in Sir "William Macleay's 

 collection, in the Australian Museum, and also in my own 

 collection. The following description is from a specimen in my 

 collection. The ^ I have not seen. 



$■ — Of a bronze colour above, under side black ; palpi and 

 first joint of antennse reddish, the rest of the antennae darker. 

 Head narrow, smooth, a deep round puncture on each side of the 

 clypeus ; clypeal suture lightly marked ; the transverse impression 

 across the vertex broad and distinct ; eyes rather prominent ; post- 

 ocular prominences small. Prothorax narrow, a little longer than 

 broad (3| x 3} mm.), subconvex, hardly flattened along the 

 median line ; basal part defined, yet not declivous behind ; sides 

 lightly rounded, broadest at about half the length, narrowed to 

 the base ; the anterior angles not at all marked ; the basal angles 

 right angles ; marginal border narrow, not widened on the 

 anterior angles, sinuate on the sides before the basal angles,
