FIRST DIVISION. 



Abdominal spiracles placed on the connective membrane of the dorsal and 

 ventral segments Scara.b.eidj-: Laparosticti. 



A-. Ligula membraceous, free. 



B-. Abdomen consisting of six ventral segments. 

 C^. Mandibles hidden by the clypeus. 



D^. Posterior tibise with one apical spur . . . ..•. Coprincc. 



D'. Posterior tibiae with two apical spurs. 



Antennae nine-jointed ApJiodiiittC. 



G\ Mandibles not hidden by the clypeus. 



c5. Antennae nine-jointed CJclroniiitc. 



c'-'. Antennae ten-jointed. 



d-. Abdominal segments free Orphninc?.. 



d^. Abdominal segments, except the apical one, soldered.. Hybosorina. 



c^ Antennae eleven-jointed . . . . Geotrupuuc. 



A^ Ligula horny, almost fused with the mentum. 



B\ Abdomen consisting of five ventral segments Trogince. 



SECOND DIVISION. 



Abdominal spiracles placed partly on the connecting membrane, partly on the 

 ventral segments Scarab.eid.e Pleurosticti. 



A. Abdominal spiracles placed almost in a line, but only the basal 

 three on the connecting membrane, the terminal one not 

 usually covered by the wing-cases Melolonthincc . 



A. Abdominal spiracles on two lines, the basal three on the con- 

 necting membrane, the others, very diverging, on the ventral 

 segments. 



a-. Claws of the tarsi unequal, labrum distinct, free . . EiLtelliuc. 



a^. Claws of the tarsi equal, labrum not visible; 



b^. Mandibles projecting beyond the clypeus, front coxae 



transverse, deeply sunk in the cotyloid" cavities . . Dijnastincc. 



b\ Mandibles hidden by the clypeus, front coxae not very 



transverse, and projecting from the cavities . . . . Cetonina. 



With the exception of the GlaphyrincB, all the sub-families are 

 represented in South Africa. I have created a new sub-family for 

 the reception of the genus Chiron, which can certainly not be 

 included in the AphodiincE, and I have placed the DynastincB after 

 the Orphnince, with which they have manifest affinities.
