the model. The specimen is unfortunately in too poor 
a condition for figuring. 
Locality of specimen represented in Fig. 3a., N.E. 
slopes, Mamba State, about 5000 fect, September 26, 1905 ; 
Rev. K. St. Aubyn Rogers. It will be observed that the 
mimie was captured the day after that on which its model 
was taken. 
Fic. 4. Limnas chrysippus, L., form dorippus, Klug. (= klugii, 
4a. 
Butl.), 2. This is the dominant form of chrysippus in 
British East Africa. Kilimanjaro, May 1905. 
Acrva johnstoni, form fulvescens, Oberth., ¢. An obvious 
and beautiful mimic of dorippus (Fig. 4). The ancestral 
markings persist, faint but distinct; and characteristic 
in shape and position on both wings. On the under- 
side they are more conspicuous. The basal spots on 
the hind-wing under-side are distinct, but the most 
prominent are in this form brown instead of black, and 
therefore comparatively inconspicuous. December 15-31, 
1905 : native collector.

Amauris lobengula, E. M, Sharpe, 3, from the forest, Mt. 
Chirinda (about 3600 feet). Melsetter, Gazaland, S.E. 
Rhodesia. Captured October 7, 1905, by Guy A. K. 
Marshall. The model of Figs. la and 1b. 
Acrea johnstoni, Godm., form proteina, Oberth., ¢. From 
the same locality as the last, and captured by Mr. 
Marshall on the same day. The relatively large size of 
the squarish discal patch of the hind-wing (compare Fig. 
1d on Plate XX1I) is an evident synaposematic approach 
towards the Amauris represented in Fig. 1, also charac- 
terized by an especially large discal patch.
