XXXIV. CERCERIS. 235 
carina between the base of the antennz, that colour extending 
in a curve to the upper part of the interior orbits of the eyes ; 
the first joint of the antennez yellow beneath, the rest fulvous 
and above piceous; the legs yellow, with the anterior coxe, 
trochanters, and base of the thighs above, the intermediate coxe, 
the trochanters above and the base of the thighs above, the 
upper part of the posterior coxz and trochanters, and a ring at 
the apex of their thighs, all black; the posterior tibize with a 
piceous stain at their apex, and their tarsi, excepting the first 
joint, also piceous ; the abdomen with an additional yellow band 
on the sixth segment, those of the third and fourth, continuing 
on the margin of the ventral segment, sometimes interrupted ; 
the intermediate space between the carinz of the anal segment 
deeply punctured and shining.

+44 The Philanthus quinquecinctus of Panzer is cer- 
tainly the ¢ of his Ph. interruptus, although Van der 
Linden considers it a ¢ of this species, which cannot be 
the case, from its posterior tibiz and all the tarsi being 
yellow ; and the black mark of the upper portion of the in- 
termediate femora also extends further towards the knee in 
the present species, besides his figure exactly resembles all 
the ¢ of the C.interrupta Ihave ever captured. The present 
species is very abundant at Hampstead, and at Charlton, 
near Woolwich; the ¢ preys on a small Curculio of the 
genus Strophosomus : at Hampstead it makes its burrows on 
the sandy flat above the Vale of Health, on the spot where 
a short time before its appearance the Panurgus ursinus 
abounds. It is a powerful insect ; notwithstanding which, 
and even the hardness of the integument of its prey, I have 
never found it to sting, although I have captured many 
hundreds with my fingers; in fact, I have never observed 
the genus Cerceris to make use of that organ. It appears 
to be widely distributed over the country.
