5. TEEACOt/TTS BOWKEBI. 



Teracohis boivheri, Trimen, Trans. Ent. Soc. p. 358 (1883). 



The South-western representative of T. agoi/e, to which it is very 

 nearly allied, but all the distinctions dwelt on by Mr. Trimen 

 appear to be constant. According to him it does not occur north 

 of 26° S. lat., being only recorded from Xamaqualand, Griqualand 

 "West, and Basutoland. 



6. Teeacolus ZEPHTEirs, sp. nov. 



Size and shape of T. acjoye, Wallgr. 



S . Uj)persi(le. — Fore %ving -white, with a mere trace of black 

 speckling at base, and a fine black line along costa as far as apical 

 patch ; the latter is of the same size and tint as in T. agoye, but the 

 black border along its inner edge is much narrower and more 

 clearly defined ; along the inuer side of this border is an ill- 

 defined suffusion of sulphur-yellow. The patch is bordered 

 outwardly by a narrow fuscous edging, which radiates slightly on 

 nervules. Hind iving white, the only marking being a few black 

 scales at base. Underside pure white throughout, without 

 markings of any kind. 



This interesting species is in some respects intermediate between 

 T. agoye and T. hoivheri, but Mr. Trimen, to whom I have shown the 

 type, agrees with me that it is quite distinct from either. It may 

 at once be distinguished from T. agoye by the complete absence of 

 black neuration or discal black clouding in fore wing, and by the 

 presence of the black line along costa and the yellow on disc. 

 The two latter points also distinguish it from T. bowkeri, from 

 which it further differs in the colour of the apical patch and its 

 inner black edging. 



Founded on a single male collected by Dr. Donaldson Smith at 

 " Selou," in Somaliland ; this specimen is in Miss E. M. Sharpe's 

 collection, who has attributed it to T. agoye in a paper now in the 

 press (Proc. Zool. Soc. 1896, p. 535). Miss Sharpe tells me that 

 Dr. Smith took three other specimens, which I have not seen. 



7. Teeacolus faustus. 



Papilio fausta, Olivier, Vov. Emp. Othom., Atl. pi. 33. fig. 4 

 (1801). 



Jdmais fausiina, Eeider, Eeise Xovara, Lep. p. 190 (1865). 



Teracohis Solaris, Butler, Proc. Zool. Soc. p. 135 (1876), 



Teracolus rosaceus, Butler, loc. cit. p. 134, pi. vii. fig. 6 (1876). 



Teracohis oriens, Butler, loc. cit. p. 134, pi. vii. fig. 7 (1876). 



Teracolus vi, Swinhoe, Proc. Zool. Soc. p. 437, pi. xxx. figs. 6 & 7 

 (1884). 



This species varies somewhat in the development of the black 

 markings, and has consequently been much split up, but a careful 

 examination of the fine series in the British Museum has con- 

 vinced me that the differences are worthless as specific characters. 

 It inhabits X.W. India, from Disa to the foot of the Himalayas,
