[Plates XIII. & XIV.] 



This paper is based upon a sturly of the species of the 

 ]\Ialachiid genera Hedijhius, Er., I/lops, Er., and Philhedonus, 

 Gorh., represented in the Cape Town Museum, the Durban 

 Museum, the British Museum in London, and the Hope 

 Collection at Oxford. The Cape Town material, which 

 includes the ty[)es of the various forms described or named 

 by Abeille de Perrin in 1900 and examples of most of the 

 species here enumerated, has been communicated by Dr. L. 

 Peringuey, who has allowed me to retain co-types or 

 duplicates for our National Collection. These genera, like 

 many others of the group, are based almost entirely upon 

 cj -cliaracters, and it is therefore impossible in some cases 

 to locate with any certainty a $ example when that sex 

 only is available for examination. Again, the head, antennae, 

 prothorax, or pygidium is sometimes difl'crently coloured, 

 or otherwise maculate, in the two sexes, at least in the 

 genus Hedyhius. The result is that several species have 

 been described two or three times under difl'erent names. 

 Paired examples of various S. African forms sent by 

 Dr. Peringuey, and the abundant material obtained by
