344 BRITISH BUTTERFLIES. 



by any other species of Argus ; at the base of the forewing is a spot drawn out 

 into a longish oval, and near this a smaller one of black colour ; a similar one in 

 the form of a bow of remarkable length, parallel with the inner margin ; the 

 discoidal spot double, or like two joined together ; this is followed by a row of 

 five black spots in a bent line sloping across the wing ; they are very broad and 

 surrounded by white which loses itself in the ground colour ; another row of 

 large spots follows these, which are heart-shaped and of orange colour ; the 

 margin, near the fringes, is set with spots, which the nervures, in passing through, 

 divide into separate pairs. The underside of the hindwings has, opposite the base, 

 five spots broadly ringed with white ; in the middle is a heart-shaped spot of clear 

 white ; a pair of these eye- spots are also placed opposite the inner margin, three 

 stand further towards the middle, and two opposite the apex ; the last is doubled ; 

 at the border are seven reddish-yellow spots with black edges ; these are, moreover, 

 surrounded with white. I am unacquainted with the other sex of this insect. 

 The example here illustrated was found in the neighbourhood of Erlangen. It is in 

 the rich collection of Herr Hofrath Rudolph (Esper). 



This is a remarkable aberration of A. thetis, combining the 

 characters of abs. venilia, albicincta, and arcuata. The figure may be 

 described as — $ . Black ground colour, with orange antemarginal 

 markings on hindwings, but none on forewings ; the discoidal of fore- 

 wings edged with white ; the bases of all wings tinged w T ith dark blue. 

 The underside with spot 6 of the submedian series united to the lower 

 basal spots of forewings ; hindwings with central discoidal white. 

 Staudinger and other authors have unaccountably referred this figure 

 to A. coridon. 



y. ab. venilia, Bergstr., "Icon. Pap. Diurn.," dec. L, pi. v., figs. 3-4 (1779); 

 "Norn.," iii., p. 5, pi. 1., figs. 3-4 (1779). — P.P.R. alis angulatis fuscis annulis 

 posticarum senis fulvo coerulescentibus ; subtus cinereis, maculis fulvis conicis 

 post puneta marginalia tarn in antica, quam in postica. Wings brown, with six 

 yellow, bluish-bordered, rings or crescents on the hindwings. Beneath bluish-grey, 

 with orange wedge-shaped spots edging the black marginal spots on both fore- and 

 hindwings (Bergstrasser). 



This is a 5 form of thetis {bellargus) , the ground colour of all the 

 wings fuscous, their basal areas alone bluer, the hindwings only with 

 an antemarginal series of orange lunules edged externally with blue. 

 The underside with normal spotting. 



8. ab. salacia, Bergstr., " Icon. Papil. Diurn.," dec. L, pi. v., figs. 1-2 (1779); 

 "Nom.," hi., p. 4, pi. 1., figs. 1-2 (1779). — P.P.R. alis angulatis integerrimis 

 fuscis maculis utrimque fulvis, subtus cinerascentibus. From venilia and 

 pampholyge, which are perhaps only aberrations of salacia, the latter is best 

 separated by the well-marked lunular spots on the forewings ; these are very faint 

 in pampholyge, and absent in venilia, etc. (Bergstrasser). 



Bergstrasser's solatia is the $ form of thetis (bellargus), with the 

 ground colour of the wings fuscous, tinged with blue at their bases ; a 

 submarginal series of reddish -orange lunules on all four wings, those 

 of the hindwings ocellated and edged with blue externally. The 

 underside is typical of a w r ell-spotted $ of this species. 



e. ab. urania, Gerh., " Mon.," p. 17, pi. xxx., fig. 4 (1853). Bellargus ab., 

 Hodgson, "Proc. Sth. Lond. Ent. Soc," p. 89 (1907-8); Adkin, " Proc. Sth. 

 Lond. Ent. Soc," p. 93 (1908-9).— Var. urania, Bischoff ; Turkey. This variety, 

 kindly sent to me by Herr Bischoff, of Augsburg, is very strikingly different from 

 the normal form. Herr Bischoff brought it from Turkey, where it is somewhat 

 scarce (Gerhard). 



Just as Gerhard erroneously calls the very blue 2 be figures as 

 ceronus (pi. xxx., fig. 2a) a $ , so he calls his figure of urania a $ . It 

 is, apparently, a ? of blackish tint, with blue scaling extending from 

 the base to the discoidal cell on all the wings, leaving the outer margin 

 broadly dark, without trace of orange marginal spots on any of the 

 wings. Adkin records (Proc. Sth. Lond. Ent. Soc, 1908, p. 93) the cap-
