Teracolus regina, Trimen, South Afr. Butt. ii. pl. xi. fig. 3, 2 (1889). 6 , Loangwa Valley Pass, 4090 feet alt., Senga, August 28th ; 2 , 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 T. 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 phlegyas, Butler, B. Z. S. 1865, p. 431, pl. xxv. figs. 3, 3 a (1865). Wet season, S 6, Deep Bay, March 9th, 1896. Bry season, 2 2 > Loangwa Valley forest, August 30th, and Ntonga, Loangw-a Biver, 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 T. phlegyas from those of the White Nile: they are slightly larger, but otherwise typical iu both sexes. T. phlegyas can hardly be a dry-season form of T. 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 T. Imperator taken in the middle of the dry season. Furthermore, T. Imperator cannot possibly be the T. lone of Godart, as assumed by m y friend Trimen in his ' South African Butterflies.' Not only does the distribution of T. Imperator render this highly improbable, but the description by M . Godart does not at all answer to it:- T. lone. 1. Black apical border divided. obliquely by a violet band rounded externally. 2. A conspicuous black discocellular spot on the primaries. 3. N o transverse ray on under surface of secondaries. T. Imperator. 1. Apical area violet, narrowly bordered w ith black. 2. A very faintly indicated discocellular clot, or none at all. 3. A conspicuous oblique transverse ray on under surface of secondaries. I do not doubt that M . Godart's description was made from a |
