1. Zoological Collections from Northern Rhodesia and 

 adjacent Territories : Lepidoptera Rhopalocera. By 

 S. A. Neave, M.A., B.Sc.Oxon.,F.Z.S. 



[Received November 9, 1909.] 

 (Plates I.-III .*, Text- figures 1 & 2, and a Map.) 



The following paper is the first yet published, in extenso, of 

 the collections of insects which I have had the opportunity 

 of making during recent years in Northern Rhodesia and the 

 Katanga Region of the Congo State. These collections were 

 made on two separate expeditions. The first was during 1904- 

 1906, when I was in N.E. Rhodesia as Naturalist to the Geodetic 

 Survey, then in that country. A short account of the country 

 traversed and of the vertebrates collected on that expedition has 

 already been published in the Transactions of the Literary and 

 Philosophical Society of Manchester, vol. 51, pts. I., II., III. etc. 

 The country covered was the southern third of N.E. Rhodesia 

 and the north-east portion of N.W. Rhodesia. The second expe- 

 dition began early in 1907, and practically the whole of that 

 year was spent in the Katanga region of the Congo State 

 when I was Entomologist to the Katanga Medical Commission. 

 The following year, 1908, was occupied in travelling over those 

 northern portions of N.E. Rhodesia which had not been visited 

 on my first expedition to that country. The areas covered by 

 the two expeditions are therefore contiguous, comprising the 

 whole of N.E. Rhodesia, the north-eastern portion of N.W. 

 Rhodesia, and the south-eastern or Katanga Region of the Congo 

 State. 



The appended Map and Itinerary (see p. 5) will make clearer 

 the relative positions of the localities visited. I have recently 

 published f an account of this part of Africa, more especially in 

 relation to the general features and geographical distribution. It 

 will perhaps be of interest to add a few facts important from an 

 entomological standpoint. As I have pointed out J, the country 

 divides itself into three areas : — 



(1) The low ground of the Zambezi basin, comprising chiefly 

 the valley of the Zambezi itself and of its tributary the Luangwa. 



Of this region, which is hot and low-lying, the chief characteristic 

 is the very marked differences between the wet and dry seasons.
