large, very shallow, dull punctures, which have a tendency to 

 form two lines on each interstice. The space between the 

 sixth stria and the margin is somewhat flat, without large 

 punctures ; behind the middle there are several short oblique 

 impressed lines, visible only in certain lights. Sternum 

 smooth and shining in the middle, closely punctured at the 

 sides. Abdomen dull but smooth ; the first segment with 

 some large punctures at the sides, the second and third seg- 

 ments densely and very finely punctured at the sides, the 

 fourth and fifth segments very strongly punctured. The 

 epipleural fold of the elytra has numerous distinct transverse 

 folds, giving the appearance of a ladder. 



Hah. Taveta, Masai country, at the south-east foot of 

 Kilimanjaro {J. Thomson). 



This fine species is closely related to S. cujyreus, Casteln., 

 but may be distinguished by the rather coarser sculpture, by 

 the oblique striation on the margin of the elytra, which, 

 although apparently a slight character, is very constant ; and 

 by the granules on the sides of the thorax being confluent 

 instead of isolated. 



Trichiidae. 



Ayenius suturalis, n. sp. 



<$ . Black, the elytra testaceous, with the suture and mar- 

 gin black. Head, thorax, and the body beneath clothed with 

 rather long pale pubescence. Clypeus as in A. limbatus, but 

 more finely punctured. Thorax scarcely broader in the 

 middle than at the base, more gradually narrowed in front 

 than in A. limbatus, and beginning to narrow from rather 

 behind the middle ; shining, very closely and rather strongly 

 punctured; the base sinuate on each side. Scutellum dull, a 

 little longer than in A. limbatus. Elytra a little more nar- 

 rowed at the apex than in A. limbatus , not so dull as in that 

 species, the punctuation similar, except that there is a series 

 of very closely-placed punctures along each side of the suture, 

 noi quite reaching the scutellum ; the apex rugose. Meta- 

 stemum moderately thickly punctured in the middle, very 

 closely and more finely punctured towards the sides. Abdo- 

 men not very closely punctured in the middle (but the punc- 

 tures three times as numerous as in A. limbatus) , closely 

 punctured at the sides. Pygidium closely rugulose. 



Length 13 millim. 



V . Entirely black, shining, the elytra dull. Much 

 broader than A. limbatus; the thorax rather more convex,
