1897.] BUTTERFLIES COLT/BCTED IN NATAL. 853 



98. Teracolits ithonus, Butler. 



Intermediate form (large examples of T. hyperides), Tugela 

 Eiver, near Weenen, 2500 feet, <5 , 23rd October; Durban, 

 2 , 7tli August, 1896. 



These examples are labelled as the dry-season form of T. achine, 

 but T. simplex is the dry phase of typical T, acliine ; whereas the 

 dry phase of T. ithonus is represented by T. ignifer (large), 

 T. ithonus, and T. harmonides (small) ; the wet form being repre- 

 sented by T. hero (part), and the intermediate phase by specimens 

 resembling those forwarded in the present collection. 



T. ithonus may perhaps prove to be only a race of T. achine, 

 but it appears to me rather to represent T. antevippe in S. Africa. 

 I do not believe in the presence or absence of a black inner bar to 

 the male apical orange patch being immaterial in the wet phase of 

 a species ; the dry-season forms usually want this black edging. 



99. Tebacolus achine, Cramer. 



Wet phase, Estcourt, 1 5th October ; Chuga's Hill, near "Weenen, 

 29th October ; Tugela River, near Weenen, 6th, 9th, 10th, 12th, 

 13th, and 16th November. Intermediate phase, c? , 28th October, 

 cJ {in copula with wet phase), 10th and 14th November, 1896. 



100. Teracolus ANNiE, Wallgr. 



Tugela Eiver, near Weenen, 2500 feet, 9th, 11th, and 12th 

 November ; intermediate phase, 22nd and 30th October, and 12th 

 November, 1896. 



101. Teracolits mutans, Butler. 



Tugela Eiver, near Weenen, 2500 feet, 28th and 30th October, 

 2nd, 9th, 10th, 11th, 12th, and 15th November, 1896. 



This is the T. vesta of Trimen and Marshall, but not of Eeiclie ; 

 the latter differs considerably according to the published figures, 

 and is an Abyssinian species. 



102. GrLTTTOPHRISSA CONTRACTA, Butler. 



6 , Durban, 6th August, 1896. 



This is labelled as " Pieris saba," but the latter is a very distinct 

 and purely West-African species.
