SECOND DIVISION.- 



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

 ventral segments Scarab.i'.ida-: 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 Mclolonthince . 



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 . . BiitcUnce.

transverse, deeply sunk in the cotyloid cavities .. Dijnastincc.i ^/

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



With the exception of the GlaphyrincB, all the suh-families arc 

 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 Apliodiiiue, and I have placed the Dyiiastincd after 

 the Orphnlnce, with which they have manifest afifinities.
