fLEBEIUS ARGUS. 189 



only existing as a series of marginal lunules to the orange spots on the 

 forewings. Wheeler notes (in lift.): "No doubt Bergstrasser is 

 right in his surmise that these {argyrotoxus and argyra) represent the 

 $ and $ aeyon, though the $ is, in the illustration, of a " royal " 

 blue, and the border is not sufficiently suffused ; the $ and the under- 

 side seem to settle the question. Argyra shows an exterior edging of 

 bluish- white to the spots on the hindwing of the upperside." 



t. ab. argyra, Bergstr., " Norn.," ii., p. 78, pi. xlvii., figs. 5-6 (1779). — P P.R. 

 alis rotundatis inlegerrimis fuscis, annulis in postica senis fulvis ; subtus fascia 

 utrisque lulva, senisque pone eandem in postica pupillis argenteis. With rounded, 

 uniformly brown, wings, six orange lunules on the hindwings ; on the underside an 

 orange transverse band on all the wings, with six silver pupils in the tpots on the 

 outer margin of the hindwings. Probably the ? of the preceding (argyrotoxus), 

 and the ? of aegon of the Vienna entomologists. It is quite distinct from argus, 

 owing to its size (Bergstrasser). 



The main characters of this form are the strongly-developed 

 character of the metallic spots on the underside of the hindwings, 

 the restriction of the orange lunules on the upperside to the hindwings, 

 and the pale blue antemarginal edging to the hindwings. As 

 figured by Bergstrasser, it is a $ with unicolorous forewings, with 

 darker nervures and discoidal lunule, the hindwings with a marginal 

 band of ocellated spots margined with reddish above, and with bluish on 

 the outer margin. The underside is dark grey as in the $ argyrotoxus; 

 the submedian row of ocellated spots well-developed, the orange band 

 clearly defined ; the white transverse band between the orange band 

 and submedian row of spots particularly well-marked ; the metallic 

 kernels of maximum number and size. [This figure shows the 

 necessity of caution in considering the details of hand-painted illus- 

 trations. Our first description of the underside of this figure was 

 made from the copy of Bergstrasser's w T ork in the library of the 

 Zoological Soc. of London, and reads as follows : " The underside is 

 most exceptional. The ground colour is pure white, on which the 

 usual black spots stand out conspicuously (the usual white rings, of 

 course, quite lost in the ground colour) ; the submarginal orange 

 band of all four wings normal. . As Bergstrasser suggests it as the 

 2 of argyrotoxus (fig. 4), one wonders whether the figure is unfinished, 

 and that he has overlooked the grey ground-colour, which he, perhaps, 

 intended to add last, which is very characteristic of his fig. 4. On 

 the other hand, he may have had a figure just like the one he has 

 pictured in fig. 6, but one suspects not in a $ . The $ hy[>ochiona 

 has quite white underside, but the ? hypoclnona is pale ochreous or 

 pale brown." The other description (noted above) was made from the 

 copy of this work in the library of the Natural Hist. Museum, South 

 Kensington, and it will be seen that our surmise that the figure was 

 unfinished proves to be accurate.]

 (ioze, " Ent. Beit.," iii., pt. 2, p. 83 (1780). — P.P.E. alis angulatis fuscis maculis 

 anticarum ; annulis posticarum fulvis ; pupilla subtus unica in posticis pone lulvara 

 fasciam argentea. Wings angled, brown, the fore- and hindwings margined 

 with yellow lunules ; on the underside, beyond the orange transverse band, a single 

 silvery pupil. This ocellated butterfly bears great similarity to argyra (pi. xlvii., 

 figs. 5-6); but the difference in the ocellated spots is conspicuous. The one has no 

 orange spots on the forewings, and also has six clearly defined silver pupils beyond 

 the red transverse band (on the underside of the hindwing); on the contrary.
