Mr: A. Murray on Coleoptera from Old Calabar. 89 
a slight emargination behind, on each side of which there is a 
faint elevation : in front of this shelf is a raised rounded ridge 
divided longitudinally, reminding one of the swollen upper lip 
of an otter or seal, slightly and shortly bristly, chiefly at the 
sides; this raised part projects a very little at each side both to 
the sides and in front, forming a semicircular epistome. Labrum 
transverse, entire, rather large, fringed with a moustache of 
fulvous pile. Thorax cylindrical, nearly as broad in front as 
behind, roughly tuberculate, except on the disk, where the tu- 
bercles are flattened down into flat scale-like markings ; there is 
an irregular, not very strongly marked, longitudinal dorsal stria. 
The anterior angles are produced for a space about a third or 
fourth of the length of the thorax. Seen from above, the pro- 
jections are nearly straight forward; seen from the sides, twice 
as broad as from above, and slightly turned up at the end; on 
their underside towards the base there is a tubercle; along 
the upper margin and the hollowed front of the thorax lying 
between the two projections are a number of small teeth or tu- 
bercles of different sizes; this anterior margin slopes obliquely 
to a channel in the middle, on each side of which is one of the 
more prominent tubercles ; it is lined on its upper part with a 
sparing fulvous pile, and immediately above the head it is hol- 
lowed out into two smooth shallow fovez ; there is no marginal 
edging along the front; the posterior angles, seen from above, 
are rectangular. Scutellum slightly raised, somewhat rugosely 
punctate, and longitudinally impressed. Elytra very deeply and 
coarsely punctate-striate, the striz, slightly oblique, being more 
numerous at the base than at the apex; suture depressed, most so 
near the scutellum ; there are three slightly raised coste running 
obliquely inwards from the base to the apex, the inner one starting 
at the base between the third and fourth or fourth and fifth strie ; 
and the three or four striz lying between it and the suture have 
diminished to two before it reaches the apex ; the second costa 
is separated from the first by a similar number of striz similarly 
diminishing in number as they approach the apex; the outer 
costa is scarcely observable except posteriorly ; none of the costz 
reach the apex, but stop where the elytra begin to decline to 
the apex, where, in the species which have apical teeth, they 
would have terminated in teeth; the inner costa, as usual, stops 
first ; the striation and punctuation continues equally marked 
to the apex; there is no excavation or smooth space, but the 
extreme apical margin is slightly explanate, and the edge thick- 
ened. Underside clothed with a somewhat loose woolly fulvous 
pile. 
Olivier describes and figures a species from Madagascar under 
the name of B. cornutus, with the angles of the thorax projecting ;
