not depressed, subconvex, very slightly declivous to the base, 

 broader than long (3| x 4 mm.), truncate in front ; the anterior 

 angles well marked, broadly margined, but hardly adA'anced ; sides 

 inflated, rounded off in front, obliquely narrowed behind, widest a 

 little before the middle ; the marginal border narrow, decidedly 

 widened at the anterior angles, not sinuate before the basal angles, 

 not reaching the middle of the base, the basal angles well marked, 

 veiy slightly obtuse ; the median line deeply impressed ; the 

 anterior transverse impression obsolete ; the posterior marked 

 towards the sides. Elytra oval (7 x 4| mm.), subconvex, rather 

 flattened towards the base ; the sides lightly rounded, the humeral 

 angles being about equally rounded with the hinder part ; base 

 truucate behind the peduncle ; the strise strongly marked on the 

 back, less so on the sides, first five strong and crenulate, the others 

 indistinct ; the interstices rather convex ; the first and second 

 posterior lateral punctures connected by a stria. Three last 

 ventral segments deeply foveate on each side ; a well marked 

 transverse impression extending from the fovese towards the 

 middle of the segments. Thighs cylindrical, strongly inflated 

 in the middle ; ^ with four first joints of anterior tarsi dilatate and 

 spongiose below ; middle tarsi with two joints spongiose ; last 

 joint of tarsi flat above and broad towards the base. 



Hah. — Porpunkah, at the foot of Mt. Buftalo, (on the north side) 

 Victoria. Three specimens (^J) in my collection. This species is 

 very like P. olivaceus, from which it differs inter alia in its 

 moi'e parallel elytra and broader prothorax, the sides of which are 

 less inflated in the middle and more gently narrowed behind. 



Promecodekus olivaceus. 



P. olivaceus, Macl. I.e. p. 334. 



^. — Dark bronze above, under surface a shining bronzy black ; 

 legs black with tarsi brown ; parts of the mouth and antennae 

 brown ; the first joint of antennfe and apex of palpi of a lighter 

 colour. Head rather small ; clypeus with the lateral punctures 

 distinct, behind them a short shallow impression on each side
