base to form a short humeral carina; marginal channel narrowed 

 at humeral angles. Prosternum with pectoral part protul^erant; 

 intercoxal part wide anteriorly, non-sulcate on base; episterna 

 overhanging anteriorly, minutely rugulose and finely transversely 

 striolate. 



Length 9-3-10-5, breadth 2-7-2-8mm. 



Hah. : N.S. Wales — Urana District (Sloane; common on the 

 edge of the more permanent creeks and, swamps). 



This species resembles C. australasue, Bohem., so closely that 

 it is impossible to distinguish them except by a close scrutiny. 

 The head is smoother, it is not punctate as is always the case in 

 more or less degree with C. australasue; the sinuosity between 

 the supra-antennal plates and the wings of the clypeus is less 

 marked; the antennae are a little lighter and slightly less 

 incrassate; the supra-antennal plates diverge from the head more 

 gently before the eyes; the pro thorax is more convex, more 

 strongly narrowed in front, the lateral basal impressions more 

 distinct; the elytra are more convex, the sides being more 

 declivous from the fifth stria to the margin, the basal declivity 

 is greater, the stride a little more distinctly crenulate, the sub- 

 marginal humeral carina shorter and less developed; the base of 

 the prosternum is not sulcate, and the wavy rugulosity of the 

 episterna is finer; the exteriial teeth of the anterior tibiie are 

 weaker in both sexes (especially in ^), the upper being smaller 

 and less outtui'ned, the upper internal spine is longer, straighter, 

 more acute, the apical spine is lighter in both sexes, and in ^ 

 is obtuse at the apex (in C. australasue, though the inner apical 

 spine is longer in ^ than in ^, it is bent and" pointed at the 

 apex].
