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 tlattened 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 fovese ; there is no marginal 

 edging along tlie 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 striae, slightly oblique, being more 

 numerous at the base than at the apex ; suture depressed, most so 

 near the scutellum ; there are three slightly raised costse running 

 obliquely inwards from the base to the apex, the inner one starting 

 at the base between the third and fourth or fourth and flfth striae ; 

 and the three or four striae 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 striae similarly 

 diminishing in number as they approach the apex ; the outer 

 costa is scarcely observable except posteriorly ; none of the costse 

 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 ;
