1910.] FROM NORTHERN RHODESIA. 5 



collections were all made by myself or by youthful native assistants 

 under my direction. " 



The following list of species has been arranged as far as possible 

 according to Professor Aurivillius' great work, ' Rhopalocera 

 ^Ethiopica.' I have therefore not thought it necessary to give 

 the references or synonymy of species except in the case of those 

 described since the publication of that book, or where some change 

 in the nomenclature seems desirable. In the case of the skippers 

 I have given references only to those species not mentioned in 

 Dr. Holland's paper in these 'Proceedings' for 1896. 



The Roman numerals, frequently placed after the locality, refer 

 to the months of capture. In the descriptions of new species the 

 veins are counted from the hind margin to the costa, the first 

 submeclian always being vein 2. The descriptions of the markings 

 begin, as far as possible, at the base of the costa and end at the 

 outer margin. 



The measurements given are the greatest length of the primary 

 from the middle of the base to the tip. 



In the laborious work of identifying so large a number of 

 species I am very greatly indebted to the following friends for 

 their kind assistance : — Mr. G. T. Bethune-Baker, Dr. F. A. Dixey, 

 Mr. Hamilton H. Druce, Mr. F. A. Heron, Dr. Karl Jordan, 

 Mr. G. A. K. Marshall, and finally Mr. Roland Trimen, F.R.S., 

 who has been so kind as to advise and assist me on many points 

 throughout the paper. 



I also owe much to the authorities of Magdalen College, Oxford, 

 who, by means of a generous grant, enabled me to spend in 

 Oxford the several months necessary for the production of this 

 paper. The bulk of the collection remains in the Hope Collection 

 at Oxford, where many of the specimens were set and most of 

 the systematic work done. For this I am greatly indebted to the 

 kindness of Professor E. B. Poulton, F.R.S.
