214 Mr. R. MacLachlan's Monograi-)h of 



The perfect insects are active and predaceous^ living 

 on other insects, which they pierce with their long ros- 

 trum; with this instrument they will also inflict a sharp 

 and momentarily painful wound on the fingers, when 

 incautiously handled. 



Our three species can be tabulated thus : — 



A. Terminal margin of the fifth segment in the 

 male straightly truncated ; sixth (antepenul- 

 timate) segment conical (PI. XI. figs. 6, 7a) . 

 a. Appendices of the male linear (PI. XI. fig. 



6ft) P. comntunis. 



a. a. Appendices flattened, dilated and truncated 

 at the apex (PI. XI. fig. 7b) .P. gen}ianica. 

 A A. Terminal margin of the fifth segment excavated, 

 sixth segment sub-cylindrical, not conical ; ap- 

 pendices linear (PI. XI. fig. 8, 8ft) . P. cognata. 



I have restricted the references and synonymy to those 

 authors whose descriptions or types permit of a tolerably 

 certain opinion being formed as to the species intended. 

 Both Westwood and Klug, who have monographed the 

 genus, wrongly unite all the European forms under one 

 head ; hence, I have omitted all reference to their works. 

 Stephens' collection of these insects has been re-arranged 

 since it became national property, and his horeaUs is no 

 longer recognizable with surety, as no specimen is so 

 labelled by him.
