posterior angles rounded ; border widely reflexed, strongly sinuate 

 behind each posterior angle and in middle of base; median line 

 , well marked. Elytra widely oval (ll-5x8-5 mm.), truncate 

 between humeral angles; margin wide; border reflexed, rather 

 widely folded backwards and upwards at humeral angles ; 

 marginal channel terminating abruptly at humeral angles. Legs 

 and under surface as in C. margiyiatum, Boisd. 



Length 24, breadth 8 '5 mm. 



Hab. — Victoria; Wimmera District. (Sent to me by Mr. C. 

 French). 



This species resembles C. marginatum so closely that it can 

 hardly be distinguished from it, but is nevertheless distinct. I 

 note the following differences from C marginafam .-—Its more 

 shining colour; elytra with greenish reflections — except in middle 

 of disc, the basal declivity and inflexed margins of elytra green; 

 preocular sulcus more deeply impressed ; preocular process 

 larger; eyes less convex and less strongly enclosed by the orbits; 

 sides of the head more abrupt above the eyes; two supraorbital 

 punctures on each side of head ; prothorax with the sides more 

 evenly rounded, the base wider, the posterior sinuosities more 

 marked; elytra much wider at apex, the marginal channel wider 

 and closed at humeral angle by a short ridge that crosses it and 

 connects the folded humeral border with the disc of the elytra; 

 in C. marginatum the elytra are declivous to the humeral angles 

 and the marginal channel is not closed by a ridge. 



Carenum amplicolle, n.sp. 



Robust, convex; head large; prothorax transverse; elytra sub- 

 cordate, narrower than prothorax, bipunctate on apical third; 

 anterior tibias bidentate. Black, opaque; prothorax and elytra 

 with narrow and obscure bluish margin. 



Head transverse (3-4 x 5-2 mm.), strongly declivous on each 

 side to eyes; frontal sulci deep, lightly divergent backwards; the 

 space between them rounded posteriorly and raised above the 

 plane of the occiput; preocular sulcus well marked; preocular 

 process narrow, not prominent; eyes convex, prominent, strongly
