those in the fore- wing. Cilia^ mixed fuscous and ochreous, the white 
interruptions less conspicuous than on upper side. 
^ Duller^ pcde7\ Fore-iving : a submacular narrow transverse 
orange ray from subcostal nervure, not far before apex, joins discal 
orange on third median nervule ; costal ochreous more developed. 
Hind-ioing : submarginal orange ray beginning on radial nervule, 
separated from discal orange by an irregular fuscous stripe ; anal- 
angular projection much shorter than in ^, but that at extremity of 
first median nervule rather better developed, — a deep excavation 
between the two. Under side. — As in 
Var. a. {$ and 
$ Orange in fore-wing a little broader exteriorly ; submarginal 
orange ray in hind-wing much broader on third median nervule, and 
usually completely confluent with discal orange. Under side. — • 
Hind-wing and apiccd area of fore-wing 'palc-fuscous, the neuration yelloiu- 
ochreous in parts only ; all the silvery scoots {except clisco-cclhdar ones 
of fore-wing^ mueh thickened, but decidedly less so than in Argyrasjjis, 
the arrow-head ones retaining their characteristic form. Fore-ioing : 
edging of costa, from base to middle, silvery- white. Hind-wing : no 
marked projection on first median nervule, but anal-angular one very 
prominent. 
$ Orange very pale and dull; the ray in fore-wing indistinct or 
obsolete; that in hind- wing more even than in typical Under 
SIDE. — As in 
(Hah. — Swellendam and Grahamstown, Cape Colony.) 
A few examples (three s and a 9 ) sent from near Grahamstown by 
Colonel Bowker and Mrs. Barber exhibit some divergence from the variety in 
their duller upper-side orange (especially dusky in basal half of hind-wing) and 
in the thicker, blunter silvery markings of the under side, some of which partly 
coalesce. The cjs, too, are unusually small (i in. i-3| lin.), and the fore- 
wings less produced apically. 
The markings of the head and body agree with those of Argyraspis, but are 
thinner and less conspicuous. 
In outline of wing this species is in both sexes blunter and less elbowed 
liind-marginally than Argyraspis, and the ^ has the anal-angular projection 
well developed in the hind-wing, and that at extremity of first median nervule 
small or obsolete — ^just the opposite of what occurs in Argyraspis. In most 
respects it holds a middle place between the species just mentioned and Mala- 
grida, Wallengr., but the silvery markings are remarkably thin and acute, 
more so than in the latter. The variety, however, is unmistakably closer to 
Argyraspis as regards its under-side colouring and marking ; but both forms of 
Wallengrenii differ greatly from that species in their very limited field of orange 
on the upper side, which is, on the contrary, much larger and brighter than in 
Malagrida. 
I met M'ith this butterfly rather numerously on hills near Stellenbosch in 
December 1862, and captured the paired sexes on the 2otli of that month. It 
constantly settles on the ground, and can be taken with the fingers if cautiously 
approached. 
It is with much pleasure that I dedicate this species to the well-known 
Swedish lepidopterist, Pastor H. D. J. Wallengren, tlie recorder of the ricli 
South-African collections formed by the lamented Wahlberg.
