 abundant where it occurs ; Southeud ; Margate and St. Peter's, Kent (T. Wood) ; 

 Kamsprate (in great profusion, Champion); Deal (Syme) ; Dover (C. G. Hull) ; Mr. 

 Champion has remarked that the species is only to be found while the sun is out, and 

 that if cloudy not a specimen will be seen : it seems strange that such large and 

 conspicuous insects can so soon disappear without leaving a trace behind them of their 

 place of refuge.
