Show 416 MR. J. H. LEECH ON THE BUTTERFLIES [May 3, In spring and autumn there is a large pale form of male (connected by grades with typical argia), which has been allotted to japonica, Murray (which was described from a single female). The females in spring and autumn seem to be much suffused with blue, which is not the case with the summer broods. Although I have not seen Mr. Fenton's type of alope, yet I have no hesitation in including it as a form of this species. The principal points Mr. Fenton enumerates as differences between alope and argia are (1) the deeper violet colouring, (2) the broader border to primaries, (3) the black spot absent from cell of primaries (underside). The colour of argia is very variable in intensity, and the width of tbe marginal border seems to vary in proportion to the depth of the ground-colour. With regard to the black spot in the cell of primaries (underside), I have specimens with spots of varying sizes and intensity, specimens without spots, and several specimens with a spot on one wing and not on the corresponding one. The female of alope has, I believe, not yet been described. 57. LYCJENA CLEOBIS. L. cleobis, Brem. Bull. Acad. Petr. iii. p. 472 (1861). L. argonides, Brem. Lep. Ost-Sib. p. 28, t. iii. fig. 8 (1864). Common at Gensan in June and July ; the specimens are far larger than those from the A m u r region. The males cannot possibly be confounded with agon or argus, on account of their darker colouring ; and the females differ on the underside by their brighter colour, sharper defined markings, and larger spots. 58. LYCENA ARGUS, Linn. Occurs commonly at Gensan in June and July ; also in Central Japan (Oiwake, Oct.), and is reported from Yesso. The Corean specimens are rather smaller than the Japanese, and have a broader black margin to hind wing. 59. LYCCENA .EGON, Schiff. L. micr argus, Butl. Cist. Ent. ii. p. 283 (1878). L. pseudagon, Butl. P. Z. S. 1881, p. 851. Common in Gensan in June and July. It occurs also in Yesso and in mountain districts of Central Japan. Corean specimens are usually much above the average size. Lycana iburiensis, Butl. P. Z. S. 1881, p. 852; Aid Identif. Ins. pl. 113, is a form of agon. The type is in Mr. Fenton's collection. 60. LYC-ENA ARGIOLUS, L. L. ladonides, de l'Orza, Lep. Jap. p. 20. L. levetti, Butl. Ann. & Mag. Nat. Hist. ser. 5, xi. p. 111. Common all over Japan -and Corea during the warm season, and as variable in Eastern Asia as it is in Europe. |
