those iu the fore-wing'. Cilia, mixed fuscous and ochreous, the white 

 interruptions less conspicuous than on upper side. 



$ Duller, paler. Forc-icivf/ : 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-iuing : 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 deejD excavation 

 between the two. Under side. — As in ^. 



Vak. 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. — 

 Hincl-iving and apical area of fore-wing imle-fuscous, the neuration yellow- 

 oelireoiis in p)arts only ; all the silvery spots (except disco-cellular ones 

 of fore-wing) much thickened, but decidedly less so than in Argyraspis, 

 the arrow-head ones retaining their characteristic form. Fore-ivinq : 

 edging of costa, from base to middle, silvery- white. Hind-tving : 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 $ ) 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 ^ s, too, are unusually small (i in. i-^h lin.), and the fore- 

 wings less produced apically. 



The markings of the head and body agree with those of Arggraspis, but are 

 thinner and less conspicuous. 



In outline of wing this species is in both sexes blunter and less elbowed 

 liind-marginally than Arggraqns, 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 Argi/rasjns. In most 

 respects it holds a middle place between the species just mentioned and Mala- 

 grida, Wallengr., but tlie silvery markings are remarkably tliin 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 

 MalagriJa. 



I met with this butterfly rather numerously on hills near Stellenbosch iu 

 December 1862, and captured the paired sexes on the 20th of that month. It 

 constantly settles on the ground, and can be taken with the fmgers if cautiously 

 approached. 



It is with much pleasure that I dedicate this species to the well-known 

 Swedish lepidopterist. Pastor H. D. J. Wallengren, the recorder of the rich 

 South-African collections formed by the lamented "\Yahlberg.
