TEKAC0LU8. 147 



The name of tliis species has been united with a number of others to 7'. evayorc, 

 by Mr. Guy Marshall (Cf. P. Z. S. 1897, p. 3G). I do not agree in all liis identifica- 

 tions, but quote the following note he has written upon the subject. 



" This widespread little species is certainly the most variable of all the Tcracoli, 

 as is well shown by the above lengthy list of synonyms. 



"In May 1893 I found the dry-season form of this species very plentiful in the 

 Northern Transvaal, and they there exhibited much greater variation than in either 

 Natal or Mashonaland, more especialh^ the females, which presented a wonderful 

 variety of coloration. Most of these forms have been raised to specific rank b}- 

 Dr. Butler, but he has based his species chiefly on the relative development of the 

 variable seasonal black markings in the male. We thus get a graduated series from 

 the lightly marked T. subfiimosus, through T. lijcori>i, T. Jlaminia, T. fnya, T. hiiPiia, 

 T. rmnaqncbaiHt, to T.galatMnus, in which the upperside markings approach to those of 

 the wet-season form of the species, represented by T. pldeyetonia (Boisd.). All these 

 forms exhibit the tinted and irrorated underside colouring, which in South Africa, at 

 all events, is always characteristic of the dry-season form. I have, however, seen 

 very few specimens of this type from Central Africa, and these appear to have been 

 captured in the dry belt of country referred to by Mr. Scott Elliot in his interesting 

 book on that region. It is therefore possible that in the more humid and forest-clad 

 areas the dry-season form may be represented by T. antiyone (Boisd.), which differs 

 from South African specimens in having a pure white underside, and here, too, we 

 can find every gradation of colouring linking it to T. jililoyefonia. But I can find no 

 sufficient reason for separating T. noitna (Luc.) from T. aii/iyoiio, the only difference 

 beinsf that the black borders are reduced and the variable inner-marcjinal bar and the 

 black spot on the inner edge of the apical patch, botli of which are evanescent in 

 T. anfif/onc, have quite disappeared in T. noiina. 



"The latter, again, seems to me identical with T.jaiiiesi, Butl., T. henylini (Feld.), 

 and T. ecagore (Klug.). In the arid climate of Arabia T. cvagorc appears to be the 

 normal wet-season form, the dry-season form being probably T saxeufi, Swinh., which 

 only differs in having a pink underside. 



" Of the two specimens of T. yelmhu/s in the British Museum, one has the underside 

 pure white while the other is sparsely irrorated with grey ; on the upperside of fore- 

 wings they have no inner-marginal bar, but the spot on the inner edge of the patch is 

 distinct. The\' thus form an interesting link between T. aiilif/oiic and the southern 

 dry form, being also intermediate in locality, as they came from Angola. With 

 regard to some of the other variations which have been described as species ; T. ih'iikiiix 

 is a variable form ranging across the Continent in Central Africa; it is white below, 

 and the upperside markings show ju-actically every gradation from T. erayore to
