Not only does von Bottemburg mention the brown form with 

 orange lurmles on all the wings as one of the forms known to him, 

 but the same form had already been described in 1763 by Scopoli 

 (Ent. Cam., p. 179) as alexis var. 2, and was later known to Gerhard 

 as iphis (Man., pi. xxviii., figs, la-c), except that the latter is of a paler 

 ground colour. We selected, in 1896, the latter name in combination with 

 cuneata to represent this form, which has, in addition to the typical 

 characters of alexis (var. 2) Scop, — icaras, v. Rott. — iphis, Gerh., a 

 pale bluish or whitish wedge-shaped mark on the upperside of the 

 hindwings, commencing widely just inside the marginal border and 

 pointing towards the base, ending in a point just within the discoidal 

 area.

This is a form of the $ , the forewings slightly scaled with blue 

 basally and with ill-developed fulvous submarginal spots ; the hind- 

 wings broadly blue, with dark nervures, and with small fulvous lunules 

 surmounting the marginal spots. The specimen mentioned by Gillmer 

 was taken near Hirschberg, in Bohemia, in 1904.

 wings strongly blue, without orange-red submarginal spots, which are also almost 

 entirely wanting on the undersides.

This is similar to semiclara, except that the bases of the wings are 

 typical lilac-blue and not of the bright blue tint of the former. 

 Restricting this name to the form with orange marginal lunules on 

 all the wings, that with orange lunules on the hindwings only might 

 be called thersites-caerulescens, that without orange lunules on any of 

 the wings fusca-caeritlescens.

 Brown, with lilac-blue bases to wings; a wedge-shaped mark and central spot to 

 hindwings (Tutt). 



The brown form with lilac-blue bases to the wings, the discoidal lunule 

 of the hindwings edged with pale bluish or bluish- white, and a cuneate 

 spot running from the marginal border to the discoidal area, is not at all 

 an uncommon form. Grover recorded a few as occurring at Guildford in 

 1897, and we have found it generally distributed with other forms in 

 most British localities in which we have collected.
