In a similar manner hispa?ia, with its bright lavender-blue tint, 

 shows the whole series of marginal aberrations, and we find indistincta- 

 Ji ispana, punctata -hispana, albocrena ta-h ispana , subfusca-h ispa no, a ngusti- 

 margo-hispana, and latimargo-hispana, the typical hispana being of the 

 divisa form, and similarly the suft'usa, plumbescens, and other forms vary 

 with regard to the margin. The hindwing groups (antea p. 10) are 

 also traceable through all the different variations of ground colour as 

 (1) pallidula-cincta, pallida la-semicincta, palliduia-cuneata, pallidnla- 

 sessilis, pallidulasuavis ; (2) caeruleocincta, caeruleosemicincta, caeruleo- 

 cuneata, caeruleosessilis, caeruleosuavis, and (8) viridescens-cincta, etc. So 

 much for the $ s. The ground colour of the upperside of the $ s varies 

 considerably in the direction of the brown ground colour (brunnescens) 

 being more or less blackish (atrescens), the palest forms we have seen 

 being those belonging to the Spanish var. albicans, Bdv. The margin 

 varies considerably ; in the most extreme form the ground colour 

 extends to the outer edge, with no trace of ocellation on the forewing, 

 and little or none on the hindwing (ab. unicolor, n. ab.). The marginal 

 spots first become edged externally with whitish or greyish, forming 

 an inconspicuous margin (ab..sv/&ocfZZtfta,n.ab.), and then inwardly with 

 fulvous lunules first on the hindwing where this tint becomes very 

 well-developed, whilst a greyish outline suffices to mark the marginal 

 ocelli of the forewing (&b.subaurantia, n. ab.), and when they show on the 

 forewing, commence from the anal angle upwards (ab. perauranti a , n.ab.), 

 until a w r ell-defined continuous band of orange crescents crosses both 

 wings, although more strongly marked on the hindwings (ab. aurantia, 

 Tutt). Whitish secondary crescents, surmounting the black border 

 edging the orange lunules of the hindwings inwardly, are sometimes 

 developed (subalbolunulata, n. ab.), and, in rarer cases, these white 

 lunules extend to the forewings in the form of a single or double 

 scries of curved spots (albolunulata, n. ab.), a form of variation ex- 

 tending to the discoidal spots which are frequently surrounded 

 with white on the forewings (ab. albicincta, Tutt), and may be simi- 

 larly ringed or replaced by white dots on the hindwings (ab. albi- 

 puncta, n. ab.). Occasionally the lunules noted above are blue instead 

 of white (caeruleolunulata), and the discoidal are blue-ringed 

 {caeruleocincta) or blue-spotted (caeruleopuncta), whilst the lunules 

 may be replaced by a series of blue 1 wedge-shaped dashes (ab. caeruleo- 

 cuneata, n. ab). South figures a good example of albolunulata and 

 albicincta combined (I\nt., xx., pi. i., tig. 11), and slates licit he took 

 8 of these and 20 examples of ab. albicincta at Ventnor in one season. 

 It is, however, in the direction of the blue scaling that the female is 

 most variable. In some examples only the basal areas of the wings 

 are strewn with blue scales (&b. basicaeruleata, n.ab.), in others the blue 



scales extend as intcnieural wedges from the base as far as. or rather 



beyond, the discoidal. suffusing the basal aid discal areas { ab. 

 Siibradiosa, n. ab.), in others more extreme the blue covers the hind- 

 wing to the margin, and the forewing as far as the discoidal ( semi-
