the antenna? are scarcely half as long as the body, and 

 that the petiole only of the abdomen, in the $ , is black. 

 His omission of other characters renders the description

Described from five males, four females, taken in the 

 Isle of Wight ; at Milford Haven ; at St. Albans ; at 

 Nunton, Wilts ; at Honor Oak (by Billups) ; in the 

 Pyrenees ; and from Walker's collection. Found several 

 times by Haliday in North Ireland, in autumn. Wesmael 

 possessed five males captured near Brussels, and Ruthe's 

 collection contains fifteen males and seven females.
