Mimicry in Mashonaland Butter t'LiES. 



Acr;vine and Lycpcniri miniics of Limnas chrysij^jitis. Incipient 

 ininiicry of Acrreas l)y LijcivnidcV. and Hesperidee. 



All tlie figures are abont ^^ of the natural size. 



All the specimens figured on this phite were cajitured by Guy A. 

 K. Marshall in Mashonaland. 



Fig. \. Lim-nHs chn/sippus 9, April 9, 1899. Captured together 

 with the specimens represented in Figs. 1«, 2, and 2a at 

 Salisbury (5000 feet). The s))ecinien is rather small ; 

 the ground-colour is of the dark-brown shade char- 

 acteristic of the Ethiopian Region. 

 \a. L. chrysipjvis, under-side (^ . Tlie pi'culiar shade of 

 the apex of the fore-wing beyond the suli-ajiical white bar 

 much resembles the ground-colour of the hind-wing, but 

 is distinguished from it by a faint greenish-orange tinge. 

 It is seen to be mimicked in the undw-side of Miniacrsea 

 mnrshalU (Fig. 2a), nnd less perfectly in that of Aci-cra 

 enrrdon (Fig. 3^). 



2. Mimamva marshalli (^ . A beautiful mimic of (hrmip}iiis 



(compare Fig. 1). Tlie shape of the sub-apical white bar 

 however more strongly suggests that of Acnea encedon 

 (Fig. 3). 

 2a. ]\f. marnhalli, under-side ^. The spots at tlie base 

 of the hind-wing as well as the shape of the sub-apical 

 bar suggest enrcdon rather than cJiriisippns (compare 

 Fig. 3ff), although the miuiicry of the lalter is strong 

 and evident. 



3. Acraea encedon ^, Dec. 1900. Captured together with the 



specimens represented in Figs. 3((, 4, G, and 7 at Umtali 

 (3700 feet). This, the typical form of the species, is seen 

 to be synaposematic with cfirysipp)ts. 

 3rt. A. encedon, under-side (^ . The under-side is seen to be 

 synaposematic as well as the ujiju'r. 



4. Catochrijsops pecidinris, underside (^ . Tlie figure well 



sliows incipient niimiciy of the black- syiotted nnder-.side 

 of an Acrasa. 



5. C. mashuna, under-side $, Nov. 7, 1897. Captured 



at the Umcheki River (4200 feet). The resemblance 

 to an Acreea is closer in this species than in the
