Artaxa simulans (Liparidae).] In Africa exactly similar phenomena recur, species of Papilio and of Diadema mimicking Danaidae or Acraeidae with the most curious accuracy.
Mr.Trimen, who studied this subject in South Africa, has recorded eight species or varieties of Diadema, and eight of Papilio, which each mimic some species of Danais; while eight species or varieties of Panopaea (another genus of Nymphalidae), three of Melanitis (Eurytelidae), and two of Papilio, resemble with equal accuracy some species of Acraea.[102] He has also independently observed the main facts on which the explanation of the phenomenon rests,--the unpleasant odour of the Danais and Acraea, extending to their larvae and pupae; their great abundance, slow flight, and disregard of concealment; and he states that while lizards, mantidae, and dragonflies all hunt butterflies, and the rejected wings are to be found abundantly at some of their feeding-places, those of the two genera Danais and Acraea were never among them.
The two groups of the great genus Papilio (the true swallow-tailed butterflies) which have been already referred to as having the special characteristics of uneatable insects, have also their imitators in other groups; and thus, the belief in their inedibility--derived mainly from their style of warning coloration and their peculiar habits--is confirmed.

In South America, several species of the "Aeneas" group of these butterflies are mimicked by Pieridae and by day-flying moths of the genera Castnia and Pericopis.

In the East, Papilio hector, P.
diphilus, and P.liris, all belonging to the inedible group, are mimicked by the females of other species of Papilio belonging to very distinct groups; while in Northern India and China, many fine day-flying moths (Epicopeia) have acquired the strange forms and peculiar colours of some of the large inedible Papilios of the same regions.
In North America, the large and handsome Danais archippus, with rich reddish-brown wings, is very common; and it is closely imitated by Limenitis misippus, a butterfly allied to our "white admiral," but which has acquired a colour quite distinct from that of the great bulk of its allies.

In the same country there is a still more interesting case.
