YO TERACOLUS. 



Dr. Butler and Mr. Guy Marshall are both agreed that Godart's name of ione is the 

 oldest, and I have followed them in this determination. I need not here reproduce 

 the long series of arguments which the above-named authors adduce as their reason for 

 not adopting the nomenclature of Dr. Trimen's standard work on the Butterflies of 

 South Africa, but I also think that Godart's name may properly be used in place of 

 Wallengren's, which Dr. Trimen employed. 



T. johina is the " dry-season " form of T. tone, and must be united with it. 

 T. speciosa is considered by Dr. Trimen to be a local form confined to the coast 

 district of Natal, but I have examined many specimens from the Transvaal and other 

 parts of Africa, and 1 consider that the range of the species must be extended as 

 detailed above. He lias also identified specimens from Manica Land and Ovampo 

 Laud as belonging to T, ione. 



Dr. Trimen writes of T. speciosa -. " I met with it in abundance about Durban at 

 the end of January, all through February, and again at the end of March and begin- 

 ning of April 1867. Colonel Bowker has taken it freely in December also. The 

 red-tipped form of the female is much less frequently met with than the other. I fell 

 in with three specimens only during my visit, and Colonel Bowker has also noted its 

 scarcity as compared with the black and white female. The lovely male is a very 

 active and even rapid flyer, but the female is much slower in her movements. Both 

 sexes are fond of flowers, and I captured the finest specimens I obtained on those of 

 Finca rosea and of Lantana in the Botanic Gardens on the Berea Hill. On the 1st 

 of February I observed and netted a male and a red-tipped female playing together 

 close to the ground. I did not meet with the species anywhere away from the 

 neighbourhood of Durban." 



Of T. jobina, which he was inclined to separate from T. speciosus in 1889, 

 Dr. Trimen also observes : " T. johina seems to occur solely as a winter (or dry- 

 season) butterfly. Apart from the non-typical individuals just mentioned as captured 

 in April (which are, however, much nearer to true T. jobina tlian to T. speciosus), all 

 the specimens whose dates of capture are known to me were taken in iMay, June, 

 July, and August. I never saw this small form during my summer visit, which 

 ended on April the 9th ; nor, on the other hand, am I aware of T. speciosus appearing 

 on the wing except in tlie summer or wet-season. It seems not impossible that the 

 two butterflies may turn out to be summer and winter broods of the same species 

 (this is the opinion of Mr. A. D. Millar, an observer of long residence at Durban). 

 The dated specimens of T. jobina, which he has kindly sent to me, are two males 

 captured on the 22nd of August, one male on the 22nd of September, and two males 

 on the 24th, but this could only be proved by careful breeding from the egg. As far 

 as my records go, T. jobina has a wider range than 7\ speciosus, Colonel Bowker having
