antenne ferruginous, the three or four last joints piceous ; 
mandibles ferruginous. 
Thorax and legs ferruginous, the latter sometimes piceous ; 
the anterior tarsi slightly ciliated, and all the tibiz spinose. 
The abdomen black, and shining; the fifth segment piceous 
at its margin, and the last ferruginous at its extremity ?. 
The ¢ differs in being entirely black and villose, the head 
much punctured in front, shining at the vertex ; the mandibles 
rufescent at the apex. The thorax slightly punctured, shining ; 
the dorsolum with two central parallel longitudinal lines, extend- 
ing its whole length ; another on each side, parallel with these, 
commencing opposite the tegule and reaching the apex; the 
scutellum deeply punctured, shining; the metathorax very 
rugose, with a longitudinal carina extending its whole length, 
sometimes obsolete ; the tegule and tarsi piceous, the wings 
hyaline, sometimes subfuscous, with their nervures piceous. 
The abdomen slightly punctured, shining ; the base of the seg-

Curtis, at Black Gang Chine, Isle of Wight; it has since 
been captured at the same place by Mr. Westwood, the 
Rey. G. T. Rudd, and Mr. Walker, who has also taken 
it in September at Lyme Regis, Dorset; and by the Rev. 
F. W. Hope at Southend, Essex. I have taken it fre- 
quently on Hampstead Heath, where I captured in June, 
1833, also two specimens of the male, which I believe are the 
first and only instances of its being found in England. It 
is remarkable that both the days on which I caught those 
males turned out very boisterous before noon; and both 
captures were made before 10 a.m.
