POMPILUS EXALTATUS. 65 



This species I have not found in the London district ; it cer- 

 tainly closely approaches the male of pectinipes. I have exa- 

 mined the typical specimen, and am inclined to consider it a 

 variety, or rather a dark, fresh specimen of the male of that 

 species : the emargination of the ventral segments is the same. 



12. Pompilus (Priocnemis) affinis. 



P. ater ; abdominis basi rufo-ferrugineo, metathorace irregulariter 

 transverso-rugoso, alis apicibus nigris.

Female. Length 4J-7 lines. Black, with a few long erect hairs 

 on the vertex, clypeus and cheeks ; the face slightly sericeous 

 above the clypeus ; the antennae inserted on each side of a tu- 

 bercle ; the mandibles slightly ferruginous a little before the 

 apex. Thorax : the posterior margin of the prothorax rounded ; 

 the metathorax transversely rugose, with a slight longitudinal 

 impression ; wings fusco-hy aline, with a dark border at their 

 apical margins, the nervures dark fusco-ferruginous ; the an- 

 terior tarsi slightly ciliated, the intermediate tibiae and the basal 

 joint of the tarsi spinose ; the posterior tibiae strongly serrated, 

 with the first joint of the tarsi spinose. Abdomen covered with 

 a fine white silky pile ; the first, second, and base of the third 

 segment ferruginous; the apical segment covered with short 

 fulvous pubescence, which is interspersed with long hairs. 



The Male closely resembles the female, but is smaller, the face is 

 more silvery, and the tibiae have only a few short spines ; the 

 sixth ventral segment is slightly emarginate. 



This species is very local, and has not been found near London ; 

 it has been captured at Hawley, Hants ; at Ripley and Wey- 

 bridge, Surrey ; at Southend, Essex ; at Deal, Walmer, and in 

 Norfolk. It is usually met with during August and September.
