Hab. — Mackay to Cairns, Q. 



This species is very variable in colour. Specimens from Cairns 

 have the yellow markings much reduced and of a duller colour; 

 the minute tubercles on the emargination of the clypeus are also 

 distinctly further apart. It is one of the commonest species in 

 North Queensland.
