130 MR. A. 6. BUTLER ON THE GENUS TERACOLUS. [Jan. 18 



3 b. Primaries of male with apical patch redder in tint and broader ; 

 secondaries with the veins slightly blackish, and terminating in 

 well-marked black spots. 



15. Teracolus het^ra. 



S, Callosune hetcera, Gerstaecker, in Van der Decken's Reisen in 

 Ost-Afrika, p. 365. n. 7, taf. xv. fig. 2 (1873). 



Eudara. 



This species is larger than T. regina, and in the marginal spots of 

 secondaries approaches T. ione and allies. 



3 c. Primaries of male above without black internal limitation of the 

 apical patch ; secondaries black-veined ; below whitish, with base 

 of costa yellowish, black veins, and an oblique, ill-defined, dotted 

 transverse line : female with apical patch of primaries orange, 

 crossed by black spots ; secondaries white, with marginal blackish 

 spots ; below pinkish ochraceous, with a well-marked, spotted, 

 red-brown, angulated, oblique transverse streak. 



16. Teracolus phlegyas. 



Anthocharis phlegyas, Butler, P. Z. S. 1865, p. 431 , pi. 25. figs. 3, 

 3a (1865). 



Callosune phlegyas, Kirby, Syn. Cat. p. 500. n. 5 (1871). 



White Nile {Petherick). Type, B.M. 



It is possible that this may be the species represented by Reiche 

 (Ferret & Gal. Voy. Abyss, pi. 30) as a variety of A. ione ; only it 

 is there represented with a black internal limitation of the apical 

 patch, and with no trace of a cross bar on the under surface of the 

 secondaries. 



^d. Like the preceding, excepting that the violet apical patch of 

 the male and the orange patch of the female are both larger ; 

 secondaries of male below whitish, with base of costa indistinctly 

 ochraceous, veins below not black : female with outer limitation 

 of apical patch almost obliterated by the orange colouring, the 

 black spots small ; secondaries white, with the marginal spots 

 small ; below very pale brown with the apical area and a well- 

 marked discocellular spot white ; the brown area reticulated 

 with slightly darker hatchings, and limited by an oblique whity- 

 brown streak (not angulated). T. buxtoni. 



17. Teracolus buxtoni. 

 Tei-acolus buxtoni, n. sp., supra. 



c? 2 , Between Natal and Delagoa Bay (E. C. Buxton). 



Type, B.M. 

 This is probably the South-African representative of T. phlegyas. 



3e. Size of the preceding two species ; violet apical patch of the male 

 bordered on both sides with black ; secondaries below and apex 

 of primaries with a distinct pink tinge ; costa of secondaries
