 The localities known for this rare species are Barham and 

 Pakefield, in Suffolk ; Arundel ; Hawley, near Blackwater, 

 Hants ; and Kingsdown, near Deal. It burrows, as I have 

 shown, in dock-stems, and also, as I observed, at Kingsdovvn, 

 in dead sticks of the bramble. 



The markings on the face, in this species, as well as on 

 the legs, are white ; in P. communis they are yellow. 



The male of P. variegatus has the scape of the antennae 

 dilated in the same way as the male of this species, and has 

 been forwarded to me as a coloured variety of it, but the 

 sculpture of the metathorax is very different, and in other 

 particulars they are too dissimilar to admit of being con- 

 sidered identical.

 The nauie given to this species is that which Kirby had 

 proposed in his own interleaved copy of the ' Monographia :' 

 the male was unknown to him. The propriety of uniting the 

 sexes was confirmed by my rearing them from the same 

 nidus, as I have shown in the introductory remarks. The 

 known localities for the species are Barham, in Suffolk ; Cove 

 Connnon, near Blackwater, Hants ; and Croydon, Surrey.

I only once captured this species, about twenty years ago : 



it most strongly resembles P. signata. The female is readily 



distinguished by the strong punctuation, particularly that 



on the basal segment of the abdomen. The male differs
