Mr. A. Murray on Coleoptera from Old Calabar, 459 



dibles with two longitudinal carinse, and several smaller carinse 

 within them sloping obliquely inwards. Labrum tridentate; 

 front of head with a tooth projecting on each side of labrum, 

 and one or two longitudinal grooves beside these teeth ; two 

 longitudinal fovese on each side of the front at equal distances 

 between the eyes, deepest in front ; and on each side, a little 

 on the exterior and in front of their termination, is a round, 

 flat-bottomed puncture with a depression in its centre, and a 

 faint line leading from this towards the anterior corner of the 

 head; the eyes with a very slight, scarcely observable tumour 

 behind and below them. Mentum longitudinally rugose, two 

 elongate fovese in the middle, the space between which forms a 

 ridge, which becomes the point of the middle tooth. Thorax 

 somewhat quadrate, with the posterior angles rounded behind 

 from the tooth on the margin, and alongside and within them a 

 few small papillae gathered together ; margined both on the sides 

 (which are slightly rounded) and behind, but not in front ; dorsal 

 line faint, not reaching to the front. Scutellum situate on the 

 peduncle, transverse, smooth, with a ridge across; prescutellar 

 space rugose. Elytra short and obovate, except at the base, which is 

 truncate ; deeply and broadly striate, particularly on the sides and 

 apex, where the striae are almost as broad as the interstices ; the 

 strise impunctate ; interstices impunctate and convex, particularly 

 so where the strise are deepest ; three impressions on the third 

 interstice (counting the sutural space as an interstice), the first 

 more than half-way from the base, the second about a fourth from 

 the apex, and the third on the point where the third and fifth 

 interstices combine together shortly before reaching the apex. A 

 few very minute papillae at the base degenerate into a slightly 

 rugose surface along the margin, and a row of punctures occurs 

 on the marginal space and at the base ; the margin distinct and 

 equal all round, not being expanded ; the humeral tooth distinct. 

 Under side polished and shining; division of head behind men- 

 tum marked; punctures on segments of abdomen same as in 

 preceding species ; anterior tibise furnished with two long teeth, 

 one short one behind, and a small one behind it, — so that they 

 may be said either to be bidentate and bidenticulate behind, or 

 tridentate and unidenticulate behind, it being doubtful whether 

 the third tooth should go with the large teeth or the small one; 

 intermediate tibise with one prominent projecting tooth, and a 

 number of smaller and decreasing ones ; posterior tibise without 

 teeth.
