I found a specimen of the male of this species amongst a mass of unarranged British Hymenoptera in the 
Hopeian Collection, and was informed by Mr. Hope that he took it in the Archdeacon’s close at Netley. I 
am indebted to Signor Costa, of Naples, for a knowledge of the female, now for the first time figured.

A figure of this species appears amongst a Collection of Abbots’ Drawings of Georgian Insects which I saw 
at Paris. The late Mr. E. Doubleday found it but rarely, in one spot, in a sandy pathway about one hundred 
yards from the River St. John’s, and a little South of the Bluff. A specimen, also taken by Mr. E. Doubleday, 
was in the Collection of the Entomological Club, taken at Mount Pleasant, Ohio.
