being liandled. The appearance of some species is extremely 

 local and spasmodic. As an example I may mention that on 

 my first visit I procured a single example of a new species — 

 Paroeme Gahani. During a subsequent three years' collecting 

 T never saw another specimen, till 1 found it one day literally 

 swarming in an old lumber-room, which was also ray last 

 acquaintance with the species, and affords an illustration of 

 the difficulty in learning much as to habits or time of appear- 

 ance. AJphito'pola maculosa is, in Barberton at least, destruc- 

 tive to the leaves of orange-trees, as I was informed by my 

 friend Mr. Harrison, who spoke from experience. Tithoes 

 conjinis, the largest Prionid found in the Transvaal, is not 

 altogether scarce at Rustenburg, and is found under the b;irk 

 of decaying or dead trees. It varies immensely in size — my 

 largest specimen (from Rustenburg) measures 80 millim., my 

 smallest example (from Barberton) only attains a length of 

 34 millim. 



By the aid of my collection I am able to enumerate 

 100 species as found in the Transvaal, and, as might be 

 expected, many of the smaller ones appear to be undescribed. 

 Through the assistance of the E.ev. H. A. Junod I received 

 from time to time 47 species collected in the neighbourhood 

 of Delagoa Bay. The enumeration and description of these 

 I have added as an appendix, for many of the species are 

 common to the two regions, and more will no doubt be subse- 

 quently proved to be distributed over what — the eastern 

 Transvaal and Mozambique — is practically one entomological 

 fauna, especially so far as these beetles are concerned. 



I have received the greatest assistance from Mr. J. C. 

 Gahan in the preparation of this paper, particularly in the 

 generic identifications. The description of Pixodarus of 

 Prionidas he also obligingly made at my request. 



Where not otherwise designated, the captures were my 

 own ; several friends who visited other districts of the Trans- 

 vaal helped my quest for Longicorns, and their aid is here 

 gratefully acknowledged.
