93. TERACOLUS REGINA. 
3 Q. Anthocharis regina, Trimen, Trans. Ent. Soc. London, 
3rd ser. 1. p. 520 (1863). 
Teracolus regina, Trimen, South Afr. Butt. ii. pl. xi. fig. 3, 9 
(1889). 
3, Loangwa Valley Pass, 4090 feet alt., Senga, August 28th ; 
o-. Mbalizi Valley, Unyika, Sept. 16th, 1895. 
The female contained “pale yellow ova”; she was somewhat 
worn, having probably been long on the wing. 
The receipt of these specimens, the male taken in the dry season 
and the female before the rains had fairly set in, is very interesting, 
as supporting the assertion that 7. anax is the wet-season form of 
T. regina. The entire absence of the latter from any of the 
collections previously received by us from British Central Africa 
had led me to regard this statement with considerable doubt ; but 
now I see no reason for rejecting it. 
94. TERACOLUS PHLEGYAS. 
Anthocharis phleqgyas, Butler, P. ZS. 1865, p. 431, pl. xxv. 
figs. 3, 3. a (1865). 
Wet season, 3 3, Deep Bay, March 9th, 1896. 
Dry season, 9 9, Loangwa Valley forest, August 20th, and 
Ntonga, Loanewa River, Senga, Sept. 13th, 1895. 
After carefully studying the purple- tipped species, in relation to 
the question of seasonal dimorphism, I am forced to the conclusion 
that there is no reason for distinguishing the Eastern and Central 
African examples of 7’. phlegyas from those of the White Nile: 
they are slightly larger, but otherwise typical in both sexes. 
T. phlegyas can hardly be a dry-season form of 7. imperator, 
because the specimen of the male recorded above (and which is 
fairly typical) was obtained in the middle of the rains, whilst the 
females were obtained near the end of the dry season: on the 
other hand, we have a typical male of 7. imperator taken in the 
middle of the dry season. 
Furthermore, 7’. imperator cannot possibly be the 7. tone of 
Godart, as assumed by my friend Trimen in his ‘ South African 
Butterflies’ Not only does the distribution of YZ. imperator 
render this highly improbable, but the description by M. Godart 
does not at all answer to it :— 
T. wone. T. tmperator. 
1. Black apical border divided 1. Apical area violet, narrowly 
obliquely by a violet band bordered with black. 
rounded externally. 
2. A conspicuous black disco- 2. A very faintly indicated dis- 
cellular spot on the primaries. cocellular dot, or none at all. 
3. No transverse ray on under 3. A conspicuous oblique trans- 
surface of secondaries. verse ray on under surface of 
secondaries. 
I do not doubt that M. Godart’s description was made from a
