rufo-flavous above and in front, and black behind and beneath ; 
their tibiee yellow in front with sometimes a black spot, a black 
line above and rufescent behind and below, the posterior ones 
the same as in the @, except a reddish yellow stain towards the 
apex of the femora above; the anterior tarsi pale yellow, ferru- 
ginous at their base, their apical joint more deeply coloured, the 
intermediate pair flavo-rufous, and their basal joint produced a 
little on the outside towards the apex, and at the margin of this 
process armed with robust spines, the posterior pair entirely rufo- 
piceous. ‘The abdomen subclavate ; it has an additional band to 
that of the @, and all as variously interrupted.

+4+ Panzer evidently had two species (see my observa- 
tions under C. Lindenius) in view in describing this, for he 
distinctly figures a @ and implies its being the ¢ in the 
description, having mistaken the colour of the clypeus as 
sexual. The two species are in fact extremely alike unless 
closely examined, and then it is found that besides the 
clypeus the position of the stemmata gives a difference. It 
is not so common as many of the species. I have found 
it at Caenwood near Hampstead, and at Birchwood in 
Kent ; I suspect it nidificates in putrescent wood.
