witli and below spot at extremity of cell, one above, tlie other below 
first median nervure ; base moderately suffused with dusky-grey ; costal j 
and hind-marginal black edging line very attenuated. Hind-iving : j 
basal and disco-cellular spots, and discal row of eight spots, quite as in 
Douhhdayi, but smaller and often indistinct (excepting the two near 
and. at extremity of cell, and the two beyond cell respectively above 
and below third median nervule) ; hind-marginal border consisting of a j 
terminal black line and an inner fainter festooned line enclosing between 
them seven elongate spots of the ground-colour ; towards anal angle 
the festooned line becomes fainter and sometimes obsolete. Under j 
SIDE, — Paler. Fore-ioing : apical black wanting^ replaced by greyish- 
yellow, crossed by yellow-ochreous inter-nervular rays from hind-margin ; 
no basal suflfusion ; two small black spots on costa near base ; other 
spots as on upper side. Hind-wing : pale-yellowisli, varied near base 
and as far as middle with pinkish-red (leaving rings of the pale ground- 
colour about the black spots) ; hind-marginal and sub-marginal lines 
more defined, their enclosed spots of the pale ground-colour ; a little ' 
before the border, and leaving a bounding line of the ground-colour, a 
series of broad, short, inter-nervular, yellow-ochreous rays ; spots as on 
upper side, but more constant and much better marked.

This butterfly is very closely related to A. DouUedayi, Gn^r., but at once 
distinguishable by the very conspicuous broad black tip of the fore-wing. In 
the the ground-colour is paler and with less of a fulvous tinge, and the fore- 
wing is less transparent ; while in the only $ I have seen (from Tati) there is 
no trace whatever of tlie subapical whitish bar of DoubledaTji ^ . Acrcea 
Dirccea, Westw. (loc. cit., p. 348, n. 42), seems from the short diagnosis given 
not to be separable from A. Caldarena. | 
The species appears only just to enter the extra-tropical region. Hewitson 
(/. c.) notes that it was received "in abundance" from Lake Nyassa, and had 
previously been sent from the Transvaal by Dr. Bradshaw. Specimens have 
reached the South-African Museum at different times from the Matabele ! 
Country and the Zambesi Valley, and also one from Damaraland ; while | 
recently (April 1882) Mr. F. C. Selous collected several individuals on the 
Marico and Upper Limpopo in the North- West Transvaal, and forwarded them 
to me, with many other species, for determination.
