Habitat.—Port Adelaide, Lyndoch, &c., South Australia ; 
Broken Hill, Central Australia (Coil. S.A. Mus.). 
Brunner’s description of this magnificent species is unmis- 
takably applicable to the four specimens in the Adelaide 
Museum, but as they vary in size and colour, it has been slightly 
departed from. The insects live solitarily under logs, &c., when 
the ground is dry, or under the loosely-adhering dry bark of 
Eucalypts, usually about the thicker branches. They appear to 
be much rarer now than they were some thirty years ago.
