The male type of tbis highly variable species is a dwarfed specimen 

 from the Wliite Xile, and its most distinctive character is that 

 the underside of the hind wings is white ^Aith all the neuration 

 finely blackened throughout. Prom Wadelai and Xjemps. I have 

 seen verv similarly marked specimens, which are, however, of much 

 larger size, being quite equal to the T. imperator form. The onlj^ 

 important difference between these examples and T. lacchus, Butl., 

 which is recorded from AYadelai, Kandera, and the Sabaki Valley, 

 is that the latter has the underside neuration very heavily 

 blackened, which certainly gives it a very distinct appearance ; but 

 the development of the black on neuration is sucli an eminently 

 unreliable character in this genus that I cannot consider it a good 

 species. 2\ nvogoroana from Zanguebar is identical with bacchus, 

 the differences referred to by M. Vuillot appearing to me to be 

 absolutely trivial. 7'./)7i%?/«s also varies in the opposite direction, 

 namely in the gradual loss of the black neuration below until the 

 underside of the hind wing becomes pure white without any 

 markings whatever. Such specimens, however, seem to be rare, 

 as there is nearly always some trace of the oblique dusky discal 

 ray from costa, which is so characteristic of the group. It was 

 on a dry-season specimen of this variety that Mr. Butler founded 

 his T. jalone, which has the underside of secondaries of a pinkish 

 tinge with a faint discal ray. This again merges gradually into 

 T. imperator (Central East Africa) both in the development of the 

 discal ray and in the tendency to assume a 6th spot in the purple 



descriptions by examination of the actual specimens from which they were 

 made in the Paris Museum — gives Senegal only. As late as 1847 (App. Voy. 

 Deleg. p. 587) — referring to the discoyery of T. ionc in Natal — Boisduval writes : 

 " Avant ce voyage, cette espece etait fort rai-e dans les collections. Lesquelques 

 individus que I'on connaissait avaient ete recueillis en Abyssinie ouau Senegal." 

 T. speciosus is by far the most strictly local of the known forms of purple-tipped 

 Teracoli, and even in England does not seem to have been received before 

 1 840 ; and it was not until 1857 that Wallengveu described it as distinct from 

 the recognized T. ione. On the whole 1 must still regard it as far more probable 

 that in 1818 Godart had before him one of the widely-ranging tropical forms, 

 and most likely a Senegal specimen, than that he should have been in possession 

 of a form peculiar to the Natal coast, where even the pioneer European 

 elephant-hunters and traders did not go till 1825. — R. Trimen.] *
