Female. Length 44 lines. — Black; the head and thorax coarsely 

 punctured; the apical joint of the antennae yellow beneath, 

 and two yellow spots between them at their base ; a transverse 

 line on each side of the anterior margin of the prothorax ; the 

 tibiae with a longitudinal yellow stripe at their base outside ; 

 the tarsi and tibiae simple ; the wings slightly coloured, their 

 nervures black. Abdomen : a yellow spot on each side of the 

 second segment, a subiuterrupted band on the third and fourth, 

 and a large central spot on the sixth, yellow ; beneath, a trans- 

 verse ovate spot on each side of the third and fourth segments. 



Mole. Length 4 lines.— The antennae capitate, much longer 

 than the thorax, and the joints of the flagellum from the 

 second to the tenth yellow beneath ; the clypeus yellow ; the 

 thorax with a yellow spot at the extreme angles of the collar ; 

 the anterior tibiae in front, and a yellow line on the outside of 

 the base of all the tibiae, yellow. Abdomen as in the female, 

 with the exception of the spot on the sixth segment, which in 

 the male is on the seventh. The spots on the abdomen in 

 both sexes are subject to much variation in size and in intensity 

 of colouring. 



This species is not found in the London district ; Mr. Newman 

 first captured a British specimen in Herefordshire ; it is plentiful 

 in some parts of the north of England, and has been captured 

 at Nottingham, Birmingham, and near Wakefield — at the latter 

 place as late as the 18th of July. It appears about the beginning 

 of June ; it frequents similar situations as the former species. 



Fam. 3. Pompilidae, Leach. 



Prothorax usually transverse and broader than long, in one or 

 two genera oblong-quadrate ; the posterior margin arcuate or 

 subangular ; legs elongate ; abdomen more or less oval, attached 

 to the thorax by a short peduncle.
