the rest, legs pitchy, clothed on the femora with whitish, and on the

An. bucephala.— iS^fi/)^. Nomen. 2d edit. 
Black: head very large and broad, sparingly clothed with longish 
ochreous hair in front: thorax with a few scattered hairs on the 
sides and behind: abdomen shining, glabrous, the margins of the 
segments pitchy, and the anal one tawny : femora black ; tibifc tawny, 
the anterior pair with the front dusky ; tarsi tawny ; wings iridescent ; 
stigma tawny. 
This may be only a veiy highly developed male of the Andrena 
longipes of Shuckard ; but I have seen no connecting link, in re- 
gard to the magnitude of the head, which in the present insect 
is enormous. Found in June, near Bath.
