emarginate at tip in the middle, and with the angles rounded, 

 oblique laterally, genae little prominent, oljtusely triangular, frontal 

 part tri-tuberculate, the median tubercle being much more developed 

 than the other two ; prothorax sub-parallel, moderately oblique 

 laterally towards the base which is not marginate, the discoidal 

 part has only a few scattered punctures, but the sides are more 

 densely punctured; scutellum moderately long, impressed in the 

 middle at base ; elytra oblong, striate, striae not deeply punctured 

 and not reaching the apex, intervals plane, hardly convex in the 

 posterior part and impunctate, the sixth and seventh striae reach 

 only to the median part of the humeral callus, and the eighth, which 

 is much shorter than the ninth, is obliterated towards the base for 

 about one-quarter of the length, the ninth unites with the marginal 

 one under the shoulder ; metasternum normal ; abdomen almost 

 glabrous ; anterior tibias tri-dentate and with two serrate teeth above 

 the digits. 



Length 4^-5 mm. ; width 2 mm. 



This species occurs in the whole of South Africa as well as in 

 Europe, Central and Eastern Africa, India, Australia, etc. 



Aphodius calcakatus, Bohem., 

 Insect. Caffrar., ii., p. 353. 



Entirely similar to A. Uvidus, and differs only by the great length 

 of the apical inner spurs of the posterior tibiae. Boheman in his 

 description mentions only a fine transverse groove on the frontal 

 part, but my examples, which are quite similar to the type, have in 

 both sexes three small tubercles as in A. Uvidus. 



Length 4-4^ mm. ; width If -2 mm.

The description of A. Uvidus suits this species in every point, 

 except that the elytra have no trace whatever of a discoidal longi- 

 tudinal fuscous band ; the suture is also either very slightly infuscate 

 or not at all, and the head is more deeply punctate. 



Length 4^4f mm. ; width 2 mm.
