AGRIADES THETIS. 341 



grey, hindwings smoky-brown ; spots as in typical bellargus, but enclosed in rings, 

 which are but little paler than the colour of the wing upon which they are placed ; 

 the discoidal spot of hindwings pale but ill-defined. Kent, June, 1886. (2) <? . 

 Blue-black, somewhat darker than that just described ; fringes chequered, dark grey 

 and black ; underside similar to last, but the discoidal spot of the hindwings oblite- 

 rated (Ent., xx., pp. 80-81). 



Cockerell named (Ent., xxii., p. 5) this form by reference to two 

 examples exhibited at the meeting of the South London Entomological 

 Society, held on October 7th, 1886, by Sabine (among other aberra- 

 tions of A. thetis), and described as two " black " $ s of this species, 

 one captured in 1886, the other the preceding year, in Kent (Proc. Sth. 

 Lond. Ent. Soc, 1886, p. 61). The former of these two examples was 

 recorded (Ent., xix., p. 176) as captured on June 15th, 1886, and was 

 described at length by South (Ent., xx., p. 80) = (no. 1 supra), who also 

 diagnosed (op. cit., p. 81) another example (no. 2 supra), said to have 

 been captured at Folkestone, in the autumn of " 1884 " (? 1885, as Sabine 

 said " the previous year " when he exhibited them). Austin notes 

 (Ent. Bee, ii., p. 273) two $ s taken at Folkestone, September 13th 

 and 15th, 1891, of a dark slate, almost black, colour ; whilst Briggs 

 exhibited a dark leaden-coloured $ , taken at Folkestone by Austin, 

 on September 12th, 1892 (Proc. Sth. Lond. Ent. Soc, 1894, p. 77); 

 Huckett records (Ent. Bee, iy., p. 259) an unicolorous leaden-coloured $ , 

 taken at Folkestone, August 23rd, 1893, whilst a very dark blue-brown 

 $ , with conspicuous orange tips to the antenna, taken at Folkestone 

 in September, 1875, by W. P. Weston, was exhibited by Briggs at the 

 meeting of the South London Entomological Society, November Sth, 

 1894, and Frohawk notices another (Proc. Sth. Lond. Ent. Soc, 1895, 

 p. 40) as dark leaden-blue, taken at Weymouth in August, 1892. 

 It is also recorded as having been taken at Speyer by Griebel. Mosley's 

 reference of this form (Vars. Brit. Lep., p. 95) to nrania, Gerh., with 

 the remark "not uncommon in Turkey," appears to be a bad hit, 

 not quite so amazing, however, as Dale's wild guess (Hist. Brit. 

 Butts., p. 66) about the same urania.

 chequered fringes. ?. Brown, well-scaled with blue ; fringes not chequered on 

 forewings, slightly chequered on hindwings. July, near Dartford (Lewin, Ins. 

 Gt. Brit., pi. lvii., figs. 4-5). 



It is most unusual to find examples of this species with absolutely 

 white fringes ; the best one we have was taken at Sonzier, May 25th, 

 1909, by Alderson ; the dark dashes are very faint in some eastern 

 examples, especially in the hindwings, but there is no example with 

 the fringes quite white in the British Museum coll. Ochsenheimer notes 

 (Schmett. Eur., i., pt. 2, p. 34) that the fringes of the <? are chequered 

 black and white, though this is not always the case, for he has specimens 

 before him in which the fringes of the hindwings are quite white, others 

 in which the blackish ticks are very faintly developed also in those of 

 the forewings. Hiibner figures (Eur. Schmett., pi. lxi., fig. 298) a 

 $ with white fringes on the upperside, but his fig. 299, apparently the 

 underside of the same insect, shows chequered fringes. Klopsch 

 records (Beit. Schles. Faun., ix., pp. 212-214) an example with white 

 fringes, scarcely at all chequered on either upper- or underside, of all 

 the wings, as a possible hybrid between this species and P. icarus, the
