On new Species o/'Planema. 415 
Loc. Grey mouth (New Zealand, South Island). 
Allied to C. de Lacyi (White), from Waikato, but differs 
in having the punctuation finer and closer, in having the anal 
tergite compressed, alid in being spotted with black. From 
liosoma (Hutton), from Dunedin, it may be recognized by 
having the infero-lateral portion of the tergites more strongly 
emarginate and the edge of the anal tergite laterally notched. 
LV. — Descriptions of new Species o/'Planema in the Collection 
of the British Museum. By A. G. Butler, Ph.D. &c. 
Whilst recently rearranging the Museum collection of 
AcrceincB of the Old W orld, and incorporating the fine series 
presented by Messrs. Godman and Salvin, I came upon the 
following undescribed species of Planema : — 
Planema Salvini, sp. n. 
Nearest to P. camerunica, the male with the discoidal area 
of primaries, the area below the cell, and the band crossing 
the centre of the wing golden orange instead of tawny ; the 
transverse band itself more regular, especially along its outer 
margin ; secondaries with the basal spots arranged as in 
P. jormosa and followed by a diffused wiiitish band, more 
distinctly white on the under surface : the female chiefly 
differing from that sex of P. camerunica in the much less ir- 
regular inner edging of the white belt on the primaries (which 
is less distinctly continued below the first median branch) 
and its less prominent external angle, so that the deep-brown 
apical area is broader in this species : the secondaries much 
more nearly resemble those of the female of P. formosa, but 
the white belt across them is broader and more diffused. 
Expanse of wings, (J ''5 millim., ? 93 millim. 
Fernando Po and Cameroons (from the Godman & Salvin 
Collection). 
The natural position of this species is undoubtedly between 
P. formosa and P. camerunica. 
Planema Godmani, sp. n. 
Allied to P. camerunica and P. alcinoe ; the male has almost 
the same pattern on the primaries as the latter species, 
excepting that the inner blackish edging of the central band 
is usually almost wholly lost, so that these wings become

divided into two equal parts, the apical half smoky blackish, 
the basal half bright orange-tawny ; the blackish inner 
edging, however, is always faintly, and sometimes strongly, 
represented : the secondaries are quite distinct from those of 
P. alcinoe, the basal spots being small and more restricted 
upon a reddish-tawny ground ; beyond them is a diffused 
band (traversed by the dark veins and internervular streaks), 
its centre golden orange, its extremities whitish ; the external 
area smoky brown, paler internally, sometimes becoming 
almost white as it merges into the central band. The female 
has primaries like those of P. camerunica $ , but the basal 
spots of the secondaries are more restricted and their outer 
limit forms a straighter line than in P. camerunica, whilst 
the brown basal patch on which these spots are usually placed 
is infringed upon by the broader white central belt -, the latter 
is more regular and of more uniform width throughout. 
Expanse of wings, ^ 69-78 niillim., $ 88 millim. 
Sierra Leone (B.M. and Salvin & Godman Colls.). 
We had long had a pair of this species in the Museum 
collection as P. alcinoe of Felder ; the latter, however, is 
quite distinct, both sexes showing a well-defined and rather 
narrow dusky border to the secondaries. We have a pair from 
Accra. 
Planema indentata, sp. n. 
The male has smoky-brown primaries, similar to other 
species of the P. alcinoe group, but the belt across the wing, 
excepting that it is broader and golden orange, resembles 
that on the primaries of P. elongata (^ ; the secondaries are 
like those of P. macaria, but much paler, the central area 
being broadly pale yellowish, almost inclining to whity brown, 
of course interrupted by the usual dusky veins and streaks ; 
the female has the primaries marked somewhat as in P. came- 
runica (,> , but the broad white band has its inner edge nearly 
straight, two small notches alone indicating the angular ex- 
cavations which characterize this band in P. camerunica : the 
secondaries are quite distinct, pale sandy yellow, the base 
narrowly brown, so that all the outer black spots are thrown 
into strong relief ; the external border almost as narrow as in 
P. alcinoe $ , but emitting much more prominent internervular 
blackish streaks to the middle of the wing. Expanse of wings, 
^ 78 millim., $ 100 raillim. 
One pair, Cameroons (Godman & Salvin Coll.). 
The female was taken by Dr. Preuss at Barombi. 
Quite recently Dr. Karsch has described a female Planema 
from Uganda under the name of P. albicolor, which he says 
new Species of F\a.nema. 417 
corresponds with the same sex of P. consanguinea so closely 
that the only difference of marking which he is able to point 
out is the slightly smaller size of the basal spots of the hind 
wings, " In the 5 from Uganda, however, all the yellow 
and red-brown of the wings and body of Planema consan- 
guinea are entirely white," a most singular statement ! He 
means to say that the yellow and red-brown areas of P. con- 
sanguinea are replaced by white in the female from Uganda. 
I must express my positive conviction tliat this P. albicolor is 
nothing whatever but the rare albino form which constantly 
recurs in many species of Acroiaj and which may also exist 
in some species of Planema. It is true, indeed, that the 
white forms of many species of Acroia have been described as 
distinct, but they always occur with the typical forms as 
either seasonal developments or simple sports ; the following 
may be cited : — 
Several other species have a white as well as a tawny 
form of female ; so that to found a new species upon a female 
alone, which (to all intents and purposes) differs in nothing 
but its white colouring from its nearest ally, is in the 
highest degree venturesome. Differences of pattern are 
alone to be relied upon in the Acrceince, the ground-colour 
varies enormously, tlie width of the black apical patch 
varies seasonally, the number of spots on the under surface 
varies a good deal in certain species, but the position of the 
spots, the outlines of the bands, and width of the hind wing 
border do not appear to be variable in Planema, or very 
slightly so : but in Acrcea the width of the outer border 
varies considerably. 
* This is rather a pale than a white form, and is perhaps a climatic 
variety.
