Abdomen above, black, posterior margin of tlie segments jcllow, -widest on the sides ; 

 beneath black, posterior margin of tlie segments broadly yellow, sides almost 

 entirely yellow ; last genital segment black at the base, lower margin narrowly,

Length, <? , 2 lines. 



Larger tlian P. impura, to whicli it is closely related, but the 

 colour is clearer, and tlie insect more shiny than that species ; and 

 besides it has not the fifth black spot on the vertex, which is always 

 present in the above-named. 



The description has been made from two ^ examples taken by 

 Mr. Douglas, at Dareuth, in July.
