BA (July, 
Entirely testaceous-red (with the exception of the eyes, which 
are black, and very small), very shining, and thinly clothed with seat- 
tered long yellowish hairs. Head rather narrow and elongate, with the 
vertex elevated, smooth, and exhibiting the trace of a linear depression in 
the middle of the base, and (viewed from the front) a shining Y -shaped 
depression in the middle reaching from just below the eyes to the inser- 
tion of the base of the antennz,—the parts near this depression being 
obsoletely roughened. Antenne rather slender, with the basal joint 
almost cylindrical (rather narrowest at the base) and almost as long as 
joints 3—8 taken together ; 2nd joint rather narrower than 1st, as long 
as 3 and 4 together, with no perceptible peculiarity of structure; 3—9 
gradually getting transverse; 10 and 11 forming a club, the apical 
joint being oval-conic. Maxillary palpi somewhat as in B. Curtisii, 
but with the apical joint not so long or so broadly securiform, and with — 
the basal joint rather more curved and not so abruptly thickened towards 
the apex. .Prothorax cordate, rather wider at its upper third than the 
head, thence rather straightly narrowed behind; elevated, smooth, and 
very shining in front, with a large shallow fovea on each side below the 
middle, reaching the lateral margin and connected across the base of 
the thorax by an impressed curved line. Hlytra with the sides gradually 
widened and rounded from the base to the outer posterior angle, and 
with the usual humeral plica and sutural stria, but not quite so elevated 
or laterally rounded as is usual in the genus, and with only a few obso- 
lete traces of punctures. dddomen smooth and shining. Legs elongate 
and slender ; with the femora slightly thickened and the anterior and 
intermediate tibize slightly thickened on the outer side below the 
middle: the posterior tibiew are considerably longer than the others, 
and are slightly thickened and curved inwards towards the apex. 
_ Three specimens of this very interesting species were taken by 
Messrs. F. H. and E. A. Waterhouse at the end of the summer of 1865 
in a mossy hollow on the chalk on Seaford Downs, in common with 
Trichonyx Merkelii and a small yellow Myrmica. It is rather larger 
than B. securiger or Burrellii ; but its shining appearance, light colour 
and want of punctuation, and the long basal joint of its antenne, at 
once remove it from any species to the description of which I can 
obtain access. M. Chas. Brisout de Barneville, to whom I have 
communicated it, returns it as utterly unknown at Paris.
