156 SOUTH-AFRICAN BUTTERFLIES. 



fuscous iiToratiou above median iiervure ; inner-marginal stripe fainter 

 than on upper side, but its terminal upward ray well marked, and 

 (more faintly) continued to near costa by diffused macular inner border 

 of apical patch ; disco-cellular spot well developed ; oi^ange of apical 

 patch veiy faintly indicated. Ilind-vjing : only a very faint indication 

 of elbowed discal ray. 



Variety A. {$ and $). 



$ Larger {cxp. cd., i in. /-^-^ lin.), tvith orange-yclloiu apical patch 

 someichat redder hut duller in tint, and its inner blackish border much 

 narroirer and more diffused. Fore-uing : disco-cellular dot smaller. 

 Ilind-iving : hind-marginal nervular spots very small.- Under side. — 

 Hind-uing and apical patch of furc-iving very pale reddish-creamy, irro- 

 ratcd more closely than in type-form. 



$ Exp. al., I in. 6-y lin. Pattern as in type-form ; but apical 

 orange-yellow in one example represented only by a few scales, and in 

 the other by a diffused ill-defined ray of three spots in the middle of a 

 dusJcy blackish 'paich. Under side. — Hind-wing and apical patch of 

 fore-wing paler and duller than in typical ^. 



(Hab. — Vaal Eiver, Griqualand West.) 



The $ of this very distinct species has some resemblance to Klug's 

 figures of his Ephyia, from Ambukohl {Syrnh. Fhys., pi. vi. ff. 9, 10), 

 but presents a smaller apical patch and an irrorated under side. In 

 both these characters it approaches T. Bowkeri, Trim, (see p. lOo), but 

 differs in the much deeper, warmer colour of its apical patch with its 

 narrower and fainter inner blackish border. In this last feature it is 

 not unlike Agoye, Wallengr., ^, but wants the conspicuous upper-side 

 black neuration and irroration of the latter. As regards the ^, Lais is 

 altogether different from the two South-African congeners just named, 

 that sex having the upper-side pattern and facies partly of Antcvippe, 

 Boisd., $, and partly of Antigone, Boisd., $, whereas the ^ s of Agoye 

 and Bowkeri are wholly, or almost wholly, devoid of the characteristic 

 dark stripes and rays. 



The variety above described co-exists with the type-form on the 

 Vaal River, and may possibly be a seasonal form of the latter. 



Very few examples of tins butterfly liave come under my notice. The type 

 {&. S) in the British Museum is ticketed "Orange River," and registered as 

 collected by " C. H. Pilcher, 1872." A $ from Damaraland was sent to me 

 for determination by Mr. Aurivillius in 1S81, and a $ and 5 taken on the 

 Vaal River were presented to the South-African Museum by Mr, H. L. Feltham 

 during the current year (1888). 



Of the Variety A., four examples (two of each sex) were taken by Colonel 

 Bowker on the Vaal River in 187 1, but no note accompanied them except the 

 general one (since confirmed by Mr. Feltham), that in that tract of country all 

 the TeracoU were almost confined to the immediate vicinity of the river.
