piERiN.^:. 
The Variety A. above described is linked to the type by an inter- 
mediate $ taken by Mr. A. W. Eriksson in the region between the 
north-west limits of the Transvaal and South Matabeleland. 
By means of an exquisite water-colour drawing of Wallengren's 
type, obtained for me by the kindness of Mr. Aurivillius, I have identified 
that author's Io?ie with my Variety A. of Eegina ; the markings being 
only a little less developed, and approaching those of Mr. Eriksson's 
example just mentioned. A second example was sent for my inspection 
by Mr. Aurivillius with the following note, viz. : " Referred by Wallen- 
gren to his lone^ but distinct from his type and description." This was 
a small worn example of my typical Regi7ia 
The very closely allied Hdmra, Gerst. (Glicderth.- Fauna d. Sansi- 
har-Gebietes, 1873, p. 365, t. xv. f. 2), founded on a single $ from 
Endara, near Mombas, seems to be distinguished from Begina by its 
rather larger size and redder apical patch, — the latter being also entirely 
devoid of any trace of black on its inner edge. 
This magnificent species excels in beauty all its near cougeners, and is, 
moreover, the largest of the genus, with the exception of the doubtfully distinct 
Hetcera. The apical patch of the ^ is nearly twice as broad as that of lone, 
Godt, and of different colouring, the most brilliant metallic pale (almost 
glaucous) blue shifting over a ground of purplish-lake. The $ , moreover, 
stands alone in presenting an apical violet space partaking to a large extent of 
the splendour proper to that of the $ . The Variety A. is undoubtedly the 
finest form of the species, but one of the two forms of $ that are referable to 
it exhibits only traces of the purple of the typical $ , and the other none 
whatever. 
Like so many of its congeners, Eegina appears to find its " metropolis " 
between the Zambesi and the limit of the Southern Tropic, and to penetrate 
but a little distance into the extra-tropical tracts. Mr. T. Ayres, however, 
informs me that he met with the species " in numbers for a very short time in 
December 1875," among the mountains in the Lydenburg District of the 
Transvaal, and several examples (including one ? of Var. A.) taken near the 
junction of the Marico and Limpopo Kivers have reached me from Mr. Selous 
and Mr. Eriksson. Mr. John A. Bell, who in 1862 made me first acquainted 
with the butterfly, brought down from Damaraland no fewer than sixty-seven 
specimens, and informed me that it was most abundant on the Botletle, one of 
the chief streams connected with Lake Ngami. On the eastern side of the 
interior, the Makloutze River and Tati seem to be favoured stations of Eegina, 
Mr. Gates having noted it from the latter, and Mr. Selous and Mr. John L. 
Fry having each sent me ticketed specimens from both localities. Mr. Fry's 
examples from Makloutze River were taken on the 20th May 1887, and a 
S of Variety A. from Tati on the 23d January. He informs me that at the 
former place the butterfly was immerous on the purple flowers of a species of 
Cineraria.
