Very little is known of the habits of this species, it forms 

 quite small colonies and nests under ground. 



P. punctatissima, Bo<jer { = tanla Sm.) — Very like 

 coiitracta, but easily recognized in both sexes. 



(J with the apical dorsal valve of the abdomen simple, 

 scape of the antennce almost as long as the second joint of 

 the flagellum, and the body less shining. 



? and 5 darker than those of confracfa, maxillary palpi 

 only one-jointed, head somewhat shining, exceedingly finely 

 punctured, puncturation throughout finer and closer than in 

 coiitracta; eyes in the ? larger and almost touching the 

 base of the mandibles.

 at Bromley in Kent, flying in the evening at some distance

 abdomen with seven segments. I have seen examples of 

 this form from Oxford.
