106 apid^;. 



the labrum transverse ; mandibles acute ; ocelli in a triangle on the 

 vertex ; tongue acute, a little longer than the mentum ; the para- 

 glossce slender, acute, and one third the length of the tongue ; labial 

 palpi two thirds of the length of the tongue and 4-jointed ; the 

 basal joint as long as the three following united ; the maxillary 

 palpi 6-jointed. Thorax ovate ; the anterior wings with one mar- 

 ginal cell truncate at its apex, and with two submarginal cells, the 

 second receiving both the recurrent nervures ; the posterior tibiae 

 and first joint of the tarsi with a dense scopa of long pubescence. 

 Abdomen ovate. 



Three species of this genus are indigenous to this country : two 

 only have been hitherto recorded ; the third is included because 

 among the specimens of the males of P. calcaratus in the British 

 Museum one of P. dentipes was found with the locality Salisbury 

 attached to it. The genus is one of limited extent, seven species 

 only being at present known ; two of the British species occasionally 

 form rather large colonies, both appearing to prefer open commons 

 or trodden pathways in fields ; I have never found them in sloping 

 banks. They are preyed upon in the larval state by a dipterous 

 insect (Miltogramma punctata) ; and their nests are also infested by 

 a parasitic bee {Nomada fabriciana).
