cell with its apical nervure less sinuate, and its anterior 

 margin nearly two-thirds as long as its posterior, in the 

 preceding species it is scarcely half as long. 



$ with the antennas much longer and slenderer, and the 

 penultimate and apical joints forming a distinct club, these 

 two joints are sub-equal in length, and have each a deep im- 

 jjression posteriorly, the pale colour of the underside stops 

 abruptly at the end of the eleventh joint, leaving the twelfth 

 and thirteenth entirely black ; in colour and markings the 

 males of the two species are much alike. 



? much narrower than in 5 punctatn, antennje more dis- 

 tinctly clavate, the basal joints of the flagellum distinctly 

 more slender than in that species ; the pronotum is longer in 

 proportion to its width, and the entire thorax is quite twice 

 as long as wide ; the abdomen is narrower and more 

 parallel- sided, black, with two spots on the second, a 

 band or two spots on the third and fourth, and a central 

 spot on the sixth segment, yellow, the second, third, and 

 fourth segments in the specimen before me are spotted 

 also beneath, and all the tibije are pale at the base. 



L. 9-11 mm. 



J have never captured this distinct species, and am 

 indebted to Dr. Mason, of Burton-on-Trent, for the loan of 

 two of Mr. F. Smith's examples, from which I have drawn 

 up my description. It is recorded from Herefordshire, 

 Nottingham, Birmingham, and near Wakefield. 



POMPILID^. 



This family is composed of, perhaps, the most active of 

 all the members of the order ; they never fly for any long 

 distance, but proceed by means of runuing with short 

 intermediate flights; in their running movements they 

 much resemble ants; they make their nests in sandy banks, 

 &c., generally making rather irregularly-shaped holes ; 

 they nearly all provision their nests with spiders, stung so
