666" Mr. J. O. Westwood on the Paussidce, 



the antennae are situated upon the head, it appears to me that 

 when alive the insect carries them with the spines pointing 

 upwards, so that, probably, their flat inner surfaces may be 

 applied to each other. I regret not having been able to obtain 

 any information respecting its habitat.
