LYaENIDxE. 191 



spot of liiiid-margiual row vertically divided into two well-separated 

 spots. 



lu outline tlie 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 $ example from IMurraysburg 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. Mcdagrida, Wallgrn., in 

 the direction of Z. Argyrasins, but the latter, Avliich 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 Isl. Wallengren, who 

 has seen specimens wliich I have forwarded to him, informs me must be 

 referred the " var. Aglasjns" of Rhop. Afr. Aust., ii. p. 272) Z. Argijraspis 

 seems to be constantly distinguished by the very broad field of orange-fidvous, 

 icliicli extends to the costal edge of fore-wings 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 

 rotu in'Jhe hind-ivings are not sagittate, and that those of the roio beyond the 

 middle are far more irregidarly 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. Ivannemeyer was the first to communicate to me this striking form in 

 the shape of a $ taken near Burghersdorp, in the Albert Division of the Capo 

 Colony. Mr. INIuskett, in 1864 and in 1S70, sent me examples of both sexes 

 from Murraysburg. Mr. E. L. Layard showed me a specimen taken by him 

 near Beaufort West, and early in 187 1, Mr. J. H. Bowker sent me a very 

 fine (J, 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 ditter from the 

 Murraysburg specimens in their narrower fuscous border (especially in the fore- 

 wings), and in the larger silvery spots of their under side.
