Fam. DYNASTID.E. 



I did not meet with many of this family in the Transvaal. 

 Oryctes boas was very abundant in old tan, and in its larval 

 condition is, I have little doubt, eaten by the Wagtail (Mota- 

 cilla capensis], as numbers of these birds were always searching 

 the material which contained the larvae.

Fam. CETONIID^E. 



I paid considerable attention to the collection of these beetles, 

 for they appeared with the flowers, and as plants and trees 

 successively blossomed, so new species of Cetoniidae were found 

 upon the bloom. Often the time of the appearance of the 

 insect was as limited as the duration of the flower. Anoplo- 

 chilus tomentosus is found on the open veld, buried in the 

 bloom of a dicotyledonous plant somewhat resembling our own 

 Dandelion. The blooms of Asclepiads (Gomphocarpi) are 

 visited by Melinesthes umbonata, species of Oxythyrea (includ- 

 ing the widely distributed Oxythyrea cinctella}, Coptomia urn- 

 brosa, and Tephraa morosa. Diplognatha silicea is of very 

 strong flight and I only secured it on the wing, and in the 

 same manner I took the rare Ischnostoma nasuta. The two 

 commonest species are Plcesiorrhina plana and Pachnodaflavi- 

 ventris ; both are found nearly throughout the whole of the 

 summer, and their depredations on apples in the Natal Colony 

 have already been described (ante, p. 126). 



I have to thank Mr. Oliver Janson for assisting me in the 

 identification of some species of this family.
