192 A NATURALIST IN THE TRANSVAAL. 



Distinguished by the short dentiform prominence at centre 

 of front margin of clypeus, and by the two tubercles to the 

 forehead. (W. L. D.) 



Fam. MELOLONTHID^E. 



A considerable number of the flower- visiting species of this 

 family are found in the Transvaal, but in nothing like the 

 number in which they abound in more Southern Africa. 

 Species of the genera Eriesthis, Pachycnema, Monochelus, and 

 Dichelus are found on the few scattered flowers that bloom on 

 the veld, and Eriesthis semihirta is certainly the most abundant 

 and common species. 



The smaller species of the family are still so little worked 

 out that I can only make a small enumeration of those that 

 have been described. 



Eriestlds semihirta, Burm. Pretoria. 



Eriesthis guttata, Burm. Pretoria. 



Pachycnema tibialis, Oliv. Pretoria. 



Monochelus, sp. ? Pretoria. 



Dichelus vulpinus, Burm. Pretoria. 



S erica, spp. ? Pretoria. 



Trochalus, sp. ? Waterberg. 



Schizonycha, sp. ? Pretoria. 



Fam. RUTELID.E. 



To the difficult species of this family the same remark 

 applies as to the Melolonthidse they are little worked out. 

 I found, as I did in Malacca, that many species come to light, 

 and are almost only found in that way. The peculiar habits of 

 two species of Adoretus have already been described (ante, 

 p. 47). 



Popillia bipunctata, Fabr. Durban, Natal. 



Adoretus luteipes, Casteln. Pretoria. 



Adoretus , sp. ? Pretoria.
