TERACOLUS. 51 



from Damara Land uo fewer thau sixty-seven specimens, and informed me that it 

 was most abundant on the Botletle, one of the chief streams connected with Lake 

 N'gami. On the eastern side of the interior, the Makloutzie River and Tati seem to 

 be favoured stations of T. regina, Mr. Gates having noted it from the latter, and 

 Mr. Selous and Mr. John L. Fry liaving sent me ticketed specimens from both 

 localities. Mr. Fry's examples from Makloutzie River were taken on the 20th 

 of May 1887, and a male Variety a. from Tati on the 23rd of Januar}^ He informs 

 me that at the former place the butterfly was iiumerous on the purple flowers of a 

 species of Cineraria." 



With regard to the variation of this species, I quote the following observations 

 made by Dr. Trimenin his paper " On Butterflies from Manica " (P.Z.S. 1894, p. 66). 

 " There are five specimens (all males) of this splendid Teracoliis, captured in Miueni 

 Valley from the 9th to the 27th of March. These diff"er slightly from Mr. H. G. 

 Smith's figure of a Mombasa male, having on the underside less irroration basally, 

 a narrower inner black border to the violet apical patch in the fore-wings, and 

 smaller nervular hind-marginal black spots in the hind wings ; the last-named 

 markings are also much reduced on the underside of the hind wing. The black 

 spots of the discal series on tlie underside of the hind-wings vary a good deal in 

 size and distinctness, one example liaving them just as in Mr. Smith's fig. 6, two 

 others having all but the first and last larger, another wanting tlie second spot, and 

 the last wanting both second and thii'd spots ; the ground-colour is also variable, two 

 examples presenting it creamy instead of pure white. As usual in the genus Tera- 

 coliis, it is impossible to define exact limits between T. anax and T. regina. The 

 Manica males here noticed, link T. anax to the Variety a. of T. ret/ina from Damara 

 Land, and so do two others taken by Mr. A. W. Erikson, in 1885, in the belt of 

 country between the Transvaal and Matabele Land ; while, as I have noted [op. cii. 

 p. 113), another male from the latter tract is intermediate between the Variety a. 

 and typical T. regina. Of the two females taken by Mr. Selous in 1882 on the Upper 

 Limpopo, Transvaal boundary, one is typical T. regina, but the other is referable to 

 Variety A.; tlie latter is on the upper side very close to Mr. Smith's figure (7) 

 of female T. anax, but has both the basal irroration of the fore-wings and the hind- 

 marginal large black spots considerably broader — the latter, indeed, are so enlarged 

 as to meet and form a continuous border, while on the underside the corresponding 

 spots are very much smaller tban in the figure (8) of T. anax female. Looking to the 

 evidence afforded by several species of the genus, I am inclined to think that the 

 typical T. regina, with greatly reduced dark markings and more or less reddisli- 

 tinged underside, and the large T. anax form (including my T. regina Variety a.), 

 with strongly developed dark markings and white or creamy-white underside, will
