S. nigropictus, Pasc, J. Linn. Soc, x., p. 463, pi. xix., f. 11 (1870). 



S. Sagittarius, Per., Trans. S. Afr. Phil. Soc, 1885, p. 139. 



Long. 8-9^; lat. 5-7 mm. 



Colom" grey or fulvous ; the prothorax with two longitudinal black 

 stripes, edged with reddish brown ; the elytra with the suture 

 entirely grey or fulvous, on each side a black stripe extending from 

 the base to the declivity and from the 2nd interval to the 4th, which 

 stripe is broadly interrupted in the middle by an oblique brownish 

 band uniting broadly with the suture at the base and thus forming 

 a large common arrow-shaped mark, of which the apex is at the 

 base of the suture, and the apical part of the suture forms the shaft. 



Prothorax dorsally about as long as broad, sides slightly rounded, 

 broadest behind middle, gradually narrowed anteriorly, the apical 

 constriction confined to the dorsal part, the base bisinuate ; upper 

 surface convex posteriorly, deeply and remotely punctate, with a very 

 deep central furrow and sometimes a faint longitudinal impression 

 on each side of it, a deep transverse impression near apex, the apical 

 margin forming a broad transverse callus, the lateral obtusely angu- 

 lated and crenelated right to the apex of the ocular lobes. Elytra 

 short subovate, the basal margin sinuate and not broader than the 

 base of the prothorax, shoulders broadly subrectangular, sides sub- 

 parallel to beyond middle, the declivity steep but rounded dorsally ; 

 upper surface rather convex, with regular rows of large punctures 

 more or less completely hidden by the dense scaling, intervals 3 and 

 5 each with a short basal costa ; 2 and 4 each costate in the basal 

 half, crenelated and more elevated posteriorly, the latter terminating 

 abruptly at the top of the declivity, the former ending nearer to the 

 apex ; interval 6 with a row of sharply conical tubercles from the 

 shoulder to the apex. Legs black, spotted with grey or fulvous, the 

 basal three- fourths of the femora w^ith dense uniform grey or fulvous 

 scaling; tibiae scabrous, the anterior pair externally dentate, the 

 outer apical angle with a long process ; tarsi moderately long and 

 very broad. 



Damaealand. 



Type in the British Museum ; type of Sagittarius in the South 

 African Museum. 



I have seen only three examples of this strikingly marked species.
