The resemblance of tbis species to tbe preceding is very 

 •great. Apart from colour and size tbe difference seems to be 

 •confined to tbe tborax. In C Lindi tbe anterior margin is 

 two-tbirds tbe widtb of tbe posterior, tbe surface is even 

 (except that there is a fovea close within the posterior angle on 

 ■either side), and the lateral margins viewed from above appear 

 to be narrowed from the base to the apex in a bisinuate curve. 

 In C. constricta the anterior margin is three-quarters the width 

 of the posterior, there is a conspicuous depression all across 

 the base, and the lateral margins viewed from above have the 

 peculiar outline already described. In both these species the 

 true lateral margin (which cannot be seen from above) is 

 gently arched from the front to near the base, then strongly 

 rounded inwards, and then proceeds in a nearly straight line to 

 the base. This sculpture is best seen from a point of view half- 

 way between perpendicular and lateral. The fourth joint of 

 the antennae is longer than either the third or the fifth, and is 

 scarcely less produced than the fifth on the inner side. 



This is a South Australian species; I have taken it near Port 



Lincoln, and have also seen specimens taken near Adelaide.
