together, and these were exhibited to the meeting. This 



series is shown in full on p. xix. in a table to which Mr. Neave 

 has kindly added notes from his journal as well as the record 

 of additional specimens. 



With reference to the localities Mr. Neave points out that, 

 in some older maps, the Luapula, after leaving Lake Mweru 

 (it is generally called the Luvua beyond the lake), is named 

 " Webb's Lualaba," which must not be confused with the 

 real river of that name — the one we are dealing with- which 

 is much further west. 



In Mr. Neave's opinion the three dates printed in heavy 

 type in the Congo list, viz. April 18, 26 and 29, 1907, are the 

 only ones that give an accurate record of the proportions in 

 which the insects occurred. At the same time the other less 

 con plete data are of value in confirming the conclusion that 

 the insects are found in the same places, and often at the 

 same time. 



A large proportion of the specimens of all the species in 

 this table is kept together as a special series in the bionomic 

 collection of the Hope Department — a series of which Dr. 

 Eltringham wrote: "The general effect of the group as seen 

 fcogel her is that they are all alike, and when they are arranged 

 in haphazard manner there is a distinct sense of effort in 

 counting the respective numbers of the different species. I 

 know of no instance which could illustrate more forcibly the 

 reality of the resemblance " (" African Mimetic Butterflies," 

 Oxford. 1910, p. 38). 



In addition to the bionomic series many of the other speci- 

 mens recorded in the table are arranged in the systematic 

 collections of the Hope Department, together with the follow- 

 ing examples of /'. poggei taken by Mr. Neave in X.lv 

 Rhodesia: Lower Chambezi Valley, Kasama distr., 3900 ft., 

 2; Luwingu, N. of L. Bangweolo, 4200 ft., 1; Luwingn to 

 mouth of Chambezi 1!. in L. Bangweolo, 2; high plateau 

 between L. Tanganyika and the Lofu R., 4200-4500 ft., 3 

 (one of these exhibits an injury probably caused by an enemy 

 and noted before •■ apt ure). 



A scries of /'. poggei, taken by Mr. Neave in the Lualaba 

 Valley, Katanga contains the only examples of this species
