93. Teeacolus auxo, Lucas. 



Intermediate form ( = T. topTia), 6 , Tugela Eiver, 2500 feet, 

 near Weenen, 21st October, 3rd November; 5 , 9th November, 

 1896. Wet-season, c? S, 15th, 16th, and 19th November, 1896. 



The extreme dry-season form is T. keiskamma, Trimen. 



Mr. Marshall writes respecting this species as quoted in the 

 introduction to the present paper. 



94. Teracolus eigne, Boisd. 



(S d , ■wet-season phase, Tugela River, 23rd October, 5th, 11th, 

 12th, and 13th November ; $ $ , 2nd, 10th, and 14th November. 

 Intermediate phase, d $ , 22nd October ; d c? , 28th October, 

 2nd, 3rd, and 5th November. 



Mr. Marshall labels some of the specimens " T. evagore " and 

 others " T. plilegetonia,'^ others, again, " evagore-phlegefonia." 

 T. evagore is undoubtedly the dry-season phase of the Arabian 

 T. yerhuryi (both having been bred from one batch of lar\ae by 

 Capt. Nurse, who, however, followed me in incorrectly calling the 

 dry phase T. notina). T. phlegetonia is a species common to 

 AVestern Africa and the South ; it is the wet-season form of 

 T. antigone, and difFers from T. eione in having the base of the 

 primaries broadly lemon-yellow on the under surface ; this cha- 

 racter is, however, confined to the wet phase of the species. In 

 my judgment three of the examples obtained by Mr. Marshall 

 should be referred to T. antigone. 



95. Teracolus antigone, Boisd. 



Intermediate phase, S <3 , Tugela Eiver, 22nd October and 

 9th November, 1896. 



These examples correspond with my T. friga. but do not show 

 the dry characters so strongly on the under surface : one of them 

 is marked as " intermediate " and two are marked " dry." It is 

 inconceivable that wet, intermediate, and dry forms of one and 

 the siime species should be flying together, all three being in 

 equally good condition, excepting in an unusually dry and hot 

 climate in which no rainy season coiild be said to exist. 



96. Teeacolus exole, Eeiche. 



c? , Tugela Eiver, near Weenen, 2500 feet, 16th November, 1896. 



This is labelled as T. ompliale, and it may perhaps be an extreme 

 development of that species in which all three phases show a well- 

 defined wet-season upperside pattern : at any rate it is a tolerably 

 distinct form, T. exole, Eeiche, = rtc^<', Felder, being the wet form, 

 T. roxane the intermediate, and T. hyhridus (part) the dry. 



97. Teracolus osiphale, G-odart. 



S 6 , Tugela Eiver, 27th October, 12th and 14th November ; 

 intermediate phase T. omplialoides, 27th October ; dry phase 

 T. theogone, Malvern, S 6 , ? ? , 6th, 7th, 10th, 11th, and 15th 

 August, 1896.
