SPHEGID.E. 119 



a large yellow spot; in tbo $ the tormiual ventral segment 

 is scarcely emarginatc, in the ? the anterior impression of 

 the clypeus does not extend upwards beyond the centre. 



L. 9-10 mm. 



The capture of a ? of this species is recorded by Smith 

 Ent. Ann. 1801, p. 43, at Kingsdown, near Deal, but he 

 omitted it from his catalogue, published by the Entomo- 

 logical Society, and it therefore escaped my attention, and 

 I have not recorded it either in my Synopsis or catalogue ; 

 Dr. Mason was kind enough to forward me the original 

 specimen from Smith's collection, which is undoubtedly 

 referable to this species, and I hope that now attention is 

 called to it other specimens will be found.

 but distinguishable at once by the structure of the second

 nearly entirely yellow, the black band on the second, when 

 present, being at the base of the segment and not at the

 along the costal margin.
