as mentioned by Burmeister in his description of the species 

 (Handb. d. Entomol., 3, p. 735). 



Length 9-11 mm. ; width 5-5J- mm. 



Hab. Cape Colony (neighbourhood of Cape Town). 



Agenius plagosus, Per., 



Plate XLV., fig. 10. 



Trans. S. Afr. Phil. Soc, hi., 1885, p. 101. 



Male : Glabrous, black, with the antennae flavescent, and the elytra 

 pale yellow but marginate with black and having a broad sutural 

 band reaching from the apex to the median part, where it expands 

 in a quadrate patch ; clypeus slightly arcuate in front in the same 

 manner as the preceding species, but the reflexed margins are not so 

 thick ; both the head and prothorax are covered with deep, nearly 

 contiguous punctures ; the prothorax is sub -angular laterally a little 

 before the median part and evenly attenuate thence to the apex or the 

 base which is bi-sinuate with the angles acute, the punctures on the 

 disk are not as deep nor as closely set as those of the head ; scutellum 

 deeply but sparsely punctate ; elytra hardly ampliate laterally in the 

 median part, and narrower at apex than at the base, non-striate and 

 not distinctly punctate ; legs and tarsi very long ; intermediate tibiae 

 not arcuate. 



Length 11-11^ mm. ; width 6 mm. 



Hab. Transvaal (Lydenburg), Natal (Upper Tongaat).

Buccal parts of Agenius ; clypeus not longer than the head ; 

 antennal club of equal length in both sexes ; body glabrous ; elytra 

 slightly ampliated laterally in the middle, as broad at apex as at 

 base, barely covering the propygidium ; prothorax with a distinct 

 round supra- marginal impression on each side of the disk ; legs long, 

 slender, glabrous ; spurs of hind tarsi neither compressed nor blunt 

 in the female ; anterior tibiae tri-dentate outwardly in both sexes, 

 the two apical teeth nearer to one another than the third ; a 

 sternal process projecting beyond the coxae and sub-obtuse at 

 apex. 



The two species included in this genus have retained the two 

 lateral prothoracic impression which obtains in the Melolonthince,
