Aphodius (Ammoecius) dentinus, n. spec. 



This species differs from A. luguhris in the shape of the clypeus 

 which is straight at apex and has on each side two comparatively 

 long, spiniform teeth; the prothorax is a little more finely punc- 

 tured, and the intervals of the elytra, which are also plane, are 

 impunctate, and the ninth stria is also, as in the two previous 

 species, quite united with the marginal one towards the base ; the 

 anterior tibiae are tri-dentate outwardly, and obtusely serrate above 

 the outer teeth. 



Length 4-4|- mm. ; width 2 mm. 



Hah. Transvaal (Potchefstroom). 



Aphodius (Ammoecius) armaticeps, n. spec. 



Black, shining, glabrous ; edges of clypeus, palpi, and legs piceous 

 red ; clypeus straight in front and having the outer angle dentate, as 

 well as a strong and sharply triangular tooth set inwards at a 

 little distance from it, head simple, strongly punctured and with 

 the median part of the clypeus impressed ; antennae piceous red ; 

 prothorax sub-parallel from the anterior part to the middle, and 

 rounded from there to the basal part which is feebly marginate, it 

 is convex, and very deeply and very closely punctured ; scutellum 

 short ; elytra sub-geminato-striate, transversely and deeply punctate, 

 and with the geminate line in the striae more distinct and more 

 raised behind, intervals strongly carinate, and stopping a little 

 short of the apex except the first three, the first seven striae 

 reach the base, and the eighth unites with the seventh on the 

 humeral callus, while the ninth, which is hardly longer than 

 the eighth, does not unite with the marginal one ; abdomen briefly 

 pubescent ; anterior tibiae strongly tri-dentate, simple above the 

 digits. 



Length 5 mm. ; width 2 mm. ~^ 



Hah. Cape Colony (Prince Albert). 



Aphodius (Ammoecius) spectabilis, n, spec. 



Black, shining, glabrous, palpi and legs piceous red ; head punc- 

 tate and with a transverse, very distinct, hardly arcuate carina, 

 clypeus not deeply emarginate in front, genae sub-obtusely triangular; 

 near the basal part there is a distinctly carinate intra-ocular line ; 

 prothorax convex, a little ampliate laterally, produced very obliquely 

 towards the base which is very distinctly marginate, and covered
