Show 1883.] MR. A. G. BUTLER ON INDIAN LEPIDOPTERA. 153 The females of this species are yellow below, as in the males ; sometimes with a row of brown spots on the secondaries. 29. IXIAS KAUSALA. Ixias kausala, Moore, Ann. & Mag. Nat. Hist. ser. 4, vol. xx. p. 49 (1877). o* 2 • Depalpore, December 1881, January 1882. " Very common on the banks of the Depalpore lake in November, December, and January ; not observed anywhere else in this district."- C. S. Chiefly differs from what I believe to be tbe 1. pyrene of Linnaeus in the decidedly narrower black inner border to the apical patch on primaries. 30. IXIAS DEPALPURA sp. n. (Plate XXIV. figs. 6, 7.) Allied to I. agnivena of Moore, but differing in the broader and brighter orange patch on primaries and the narrower macular border of secondaries. Wings above white ; primaries with the basi-internal area almost to the middle of the wing white, tinted at base and towards the costa with bluish grey ; a broad oblique black patch across the end of the cell, continued in the male as a narrow oblique black band to the external angle, so as to separate the basi-internal and apical areas; the latter area bright orange ; the costal margin, apex, and external border black-brown, somewhat as in I. marianna; the disk in the female marked with four small black dots parallel to outer margin : secondaries white, with a marginal series of subconfluent squamose brown spots somewhat as in the female of I. dharmsala; base greyish. Under surface similar to that of I. agnivena and some examples of I. marianna, but with only four ocelloid spots towards apex upon the disk of primaries and with no large brown patch at external angle ; the ocelloid spots on the secondaries are large and white with pale coffee-brown borders. Expanse of wings 48-51 m m. Five examples. Depalpore, January 1882. " This Ixias is also very plentiful at the same place in company with /. kausala in the same months, and has not been observed anywhere else in these parts."-0. S. 31. PAPILIO DIPHILUS. Papilio diphilus, Esper, Ausl. Schmett. pl.40 B. fig. I (1785-1798). Dudhi and Shabgunge in the Mirzapore distinct, N.W. Provinces, in February 1882. The example from Dudhi is smaller than the other; and Colonel Swinhoe regards the two as distinct local forms. This may be so; but hitherto I believe all have been regarded as varieties of P. diphilus; and I should be sorry, with single specimens before me, to question the correctness of this view. 11* |
