As the specimens o£ this genus vary mncli, I do not consider it 

 advisable to note this otherwise than a variety of D. Fovtunei, which 

 it more nearly approaches than D. rugipennis. 



BRACHELYTBA. 



Leptacinus beeviceps, sj). n. 

 Niger, nitidtis ; elytris obscure testaceis, suturd regioneque scutellari 

 nigris ; eapite latitudine vix longiori, utrinque puree fortiter punctata ; an- 

 tennis pedib usque piceis. Long. 2\ lin. 



Very closely allied to L. parttmpunctatus, but a little smaller, and the head dis- 

 tinctly shorter. Head not perceptibly longer than broad, a little narrowed in front, 

 less strongly punctured at the sides than in L. parumpunctatus ; thorax in all respects 

 as in that species, with the dorsal line and lateral punctures the same. Elytra pitchy- 

 testaceous, with the scutellar region and the suture blackish, very smooth, with a 

 few punctures in a line at the suture, a line of very fine punctures from the shoulder 

 to the apex, and two or three fine punctures at the apical angle. Abdomen nearly 

 smooth, with a few obsolete punctures. 



Hab. : S. E. Africa, Zambesi. 



Ste>'US c(eruleus, sp. n. 

 Nigro-coeruleus, nitidus ; elytris uhdoininisque hasi late cceruleis, pedib us 

 testaceis, abdomine haud marginato. Long. 2^ lin. 



Head greenish, deeply excavated, distinctly but not very closely punctured, 

 with a slightly raised smooth mesial line. Thorax blue, elongate, very little enlarged 

 in the middle, strongly and thickly punctured. Elytra one-third broader than the 

 thoi'ax, as long as broad, convex, as strongly but not so thickly punctured as the 

 thorax. Abdomen not margined, sub-cylindrical, bluish at the base, blackish at the 

 apex, very finely and sparingly punctured. Legs entirely pale testaceous ; penulti- 

 mate joint of the tarsi bilobed, rather broad. 



Hal. : Port Boweu. 



StENUS GUTTULIFEE, sp. n. 



Niger, parum nitidus, crebre rugoso-punctatus ; elytris sat hrevibus, si}i- 

 gulis guttuldjiavd marginali notatis ; abdomine tenuissime marginato, seg- 

 mentis 1-4 lined mediand nitidd; femorum basi tarsisque obsolete picescentibus, 

 his a7'ticulo penultimo bilobato. Long. 2^ lin. 



Head thickly and rather strongly punctured, moderately excavated, with two 

 longitudinal impressions between the eyes. Thorax a trifle longer than broad, gently 

 arched at the sides, a little more narrowed behind than in front, very convex, the 

 surface rather uneven, vea*y thickly but not veiy strongly punctured. Elytra scarcely 

 as long as broad, rather depressed, a little narrowed at the base, a little broader than 

 the thorax, shoulders distinct, the surface rather uneven, very thickly but not very 

 strongly rugose-punctate ; each elytron with a small oblong yellow spot on the side, 

 a little behind the middle. Abdomen sub-cylindrical, scarcely narrower than the 

 elytra, the margins indicated by a fine line, a little less thickly and strongly punctured 

 than the elytra, tlie four basal segments with a smooth mesial line. Legs black, the 

 base of the femora and tarsi scarcely pitchy ; the tarsi slender, the penultimate joint 

 strongly bilobed.
