•iSO Mr. G. A. K. Marshall on 



often cited as a mirnic of L. cltrysippKH, vai". Mngii. Now 

 this is by far the commoner form of the female misipjnts in 

 S. Africa, whereas klugii appears to be extremel}' rare, in 

 fact the single specimen recorded by Trimen is the only 

 one I know of. How then can it be said to be mimicked 

 by inaria ? Again, m.isvppus is recorded in several places 

 in South America, where I believe chrysipims does not 

 occur. It seems to require further investigation." 



" U'liihmiaas Mouth, Natal; Sept. 3, 1897. — I certainly 

 think that I have more frequently seen Ilypolimnas 

 misiiypus (female) in company with L. chrysijjpus than 

 with its own male. The latter is fond of haunting the 

 tops of kopjes in company with various species of Precis 

 (which always occur in such localities), but I have never 

 seen the female do so, neither does chrysipims." 



The range of the forms of encedon corresponds remark- 

 ably well with the forms of chrysipjms. Mr. Marshall 

 states above that the klugli-Wke form claira is extremely 

 rare in the south where khigii is absent. Passing north- 

 ward on the east side of the continent it gradually in- 

 creases in proportionate numbers till it preponderates over 

 encedon where Idugii preponderates over clirysippus. On 

 the West Coast all forms seem to occur, but recently the 

 white-hind-winged (dcippina (Plate XV, fig. 7) has been 

 found there in greater numbers than elsewhere. (Auri- 

 villius, Rhopalocera Ethiopica, Stockholm, 1898, pp. 583, 

 534; Poulton, Proc. Linn. Soc. Lond., 113th Session, p. 0, 

 Report of Meeting Dec. 20, 1900, where however the name 

 encedon is erroneously printed unicolor.) The distribution 

 of the Lycffinid mimic corresponds equally well, marshalli 

 with chrysippus in the south (Maslmnaland), dohertyi with 

 the predominant Idugii in British East Africa. H. misippus 

 $ shows upon the whole an almost complete lack of corre- 

 spondence, for inaria is common nearly everywhere, while 

 Idugii is confined to the range described on p. 476. In British 

 East Africa, however, misipptis ^ corresponds well with the 

 two forms of its model ; while on the west, where alcippus 

 is the only form, the want of geographical coincidence is 

 most striking, for the inaria form is relatively abundant, 

 while neither in it nor in the type-form, so far as I am 

 aware, is there any special tendency towards the develop- 

 ment of white in the hind-wings. It is a striking fact 

 that the Acroeine mimic si ion Id exhibit so dope a co- 

 incidence with the geographical range of its Danaine
