Elongate, oblong-oval, rounded in front and behind, depressed, 

 shining. Head entirely clear ferruginous, smooth, and without 

 impressions. Antenna) and palpi testaceous. Thorax brown, 

 with broad ferruginous margins encroaching on the disk (or 

 perhaps it may be more accurate to say — thorax ferruginous, 

 with the anterior and posterior margins, especially towards the 

 middle, becoming embrowned) ; it is rather more than twice as 

 broad as long, broadly emarginate in front, cut nearly straight be- 

 hind, being only slightly bisinuate, broader behind than in front ; 

 very slightly rounded on the sides, which have an extremely slen- 

 der edging : the anterior angles projecting, and rounded at the 

 point ; posterior angles nearly right-angled : a narrow, very finely 

 punctate impression runs along and parallel to the anterior 

 margin, and a short, curved, similarly punctate impression lies 

 parallel to the base on each side of the middle, commencing 

 nearly opposite to the exterior of the scutellum. Scutellum 

 short, broad, and ferruginous. Elytra long, depressed, brown, 

 with a narrow ferruginous transverse band along their base, and 

 an elongate curved ferruginous patch lying parallel to the exte- 

 rior margin at the apex ; they have three scarcely perceptible, 

 interrupted, longitudinal lines of points lying more to the ex- 

 terior than the suture, the middle line most interrupted, being 

 reduced to an occasional point : the reflexed portion of the elytra 

 at the base ferruginous. Under side ferruginous, shining, and 

 impunctate. Legs paler, especially the four anterior.^ 



This is, I think, the first instance of an Agabus having been 

 recorded as found in Africa south of the Mediterranean district. 

 The present species has very much the form and size of Hydro- 

 ])orus memnonius ; but the five-jointed tarsi, the presence of a 

 scutellum, and the unstriated elytra readily indicate its true 

 position.
