spot of hind- marginal row vertically divided into two well-separated 
spots. 
In outline the wings of the $ are more even and blunted, the 
fore-wings being less elbowed below apex, but with a slight prominence 
at end of first median nervule. 
A streak margining the front of each eye ; another at lateral base of 
each palpus ; and six spots on each side of the abdomen (the latter 
edged with black) ; silvery- white. General colouring of body fuscous- 
ochreous, with two longitudinal whitish stripes on each side of breast ; 
legs ochreous, with whitish femora. 
A 9 example from Murraysburg differs from other specimens in the great 
breadth of the fuscous bordering, particularly in the fore-wings. 
There is a series of variations which leads from Z. Malagrida, Wallgrn., in 
the direction of Z. Argyraspis, but the latter, -which is the largest and finest 
form I have seen, is sufficiently well marked in both sexes to demand separa- 
tion as a species. From the type Z. Malagrida (to which M. Wallengren, who 
has seen specimens which I have forwarded to him, informs me must be 
referred the " var. Aglasjns^' of liJtop. Afr. Aust., ii. p. 272) Z. Argyraspis 
seems to be constantly distinguished by the very hroad field of orangefidvous, 
ivhicJi extends to the costal edge of fore-ioings on the upper side, and by the 
much brighter, more clearly defined, and rounder silvery spots of the under side. 
As regards the latter, it is very noticeable that the spots of the hind-marginal 
row in^the hind-ioings are not sagittate^ and that those of the row beyond the 
middle are far more irregularly placed than in Malagrida^ and present no 
approach to the continuity which almost forms a stripe in that species. In 
addition to these distinctions should be mentioned the much larger size of 
Argyraspis, and the different outline of the wings, which latter consists in a 
marked prominence of the apical region of the fore- wings, and the production 
of the slight dentations in the hind- wings of Malagrida at the ends of the sub- 
median nervure and first median nervule into distinct pointed tails. 
Dr. Kannemeyer was the first to communicate to me this strilving form in 
the shape of a $ taken near Burghersdorp, in the Albert Division of the Capo 
Colony. Mr. Muskett, in 1864 and in 1870, sent me examples of both sexes 
from Murraysburg. Mr. E. L. Layard shoAved me a specimen taken by him 
near Beaufort West, and early in 1871, Mr. J. H. Bowker sent me a very 
fine $ , taken "on the way from Murraysburg to Somerset East." 
In August 1873 I had the good fortune to meet with this butterfly in the 
ISTamaqualand District, capturing two of each sex. These specimens were all 
easily taken, sitting constantly on the bare ground. They differ from the 
Murraysburg specimens in their narrower fuscous border (especially in the fore- 
wings), and in the larger silvery spots of their under side.
