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,

d , Callosune hetccra, Gerstaecker, in Van der Decken's Reisen in 

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



Endara. 



This species is larger than T. rer/ina, 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. 



10. TERACOLUS PHLEGYAS. 



Anthocharis phlegyas, Butler, P. Z. S. 18G5, p. 431 , pi. 25. figs. 3,

White Nile (PethericA ,. Type, B.M. 



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

 (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 uuder surface of the 

 secondaries. 



3d. 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 

 w ith slightly darker hatchings, and limited by an oblique whity- 

 brown streak (not angulated). T. buxtoni. 



17. Teracolus buxtoni.

Type, B.M. 

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



3 e. 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
