Wings below paler, transversely striated with darker lines, the disk (particularly in the female) suffused with lilacine grey, the ocelli with pale zones, and in the male1 with whitish instead of orange irides, those of the primaries situated as on the upper surface, but the subapical one, particularly in the female, greatly reduced in size; the outer border with sharply defined zigzag inner edge towards apex, in the female suffused with ferruginous, the intersecting submarginal line being dark ferruginous ; a broad central belt, the inner edge of which is obsolete in the male but sharpely defined by a white-bordered ferruginous line in the female; the outer edge slightly undulated and angulated on all the wings, dark brown with pale border in the male, ferruginous with white border in the female; secondaries with seven discal ocelli, of which the second, third, and seventh are very small and the fifth the largest. Expanse of wings, S 1 inch 6 lines, $ 1 inch 9 lines. Two worn males and one fresh female were obtained. CHARAXES BALFOURI, sp. u. (Plate XVIII. fig. 6.) (No. 741.) Allied to C.varanes, from which it differs as follows:-The outer margins of all the wings dentated at the extremities of all the veins, that of the secondaries with two tails of the ordinary type, that at the end of the first median branch being rather short (3 to 4 millimetres), and that at the end of the third branch of about double the length, more slender and gradually tapering towards the point: wings above deep mahogany red, rather paler on the basal half; primaries with all the markings as in C. varanes, excepting that the spots beyond the cell are not so black : secondaries with the rounded black spots only distinct towards the apex ; outer border black with a marginal series of pale blue lunules fringed with snoio-ivhite. Body laky brown, prothorax and head olivaceous. Under surface of wings very like 0. varanes, but the general colour greener, most like that of the darkest Natal specimens, the black characters on the basal area better marked, the white stripe limiting the broad basal area wider, more diffused externally, and distinctly angulated on all the wings: the ocelli on the secondaries slightly narrower, and the outer margin of these wings bordered with a series of large black and white lunules. Expanse of wings 3 inches 8 lines. One specimen of this extremely interesting species was captured. The allied species C. varanes has hitherto been referred to the genus Philognoma on account of its only having one peculiarly shaped tail to the secondaries; but the arrival of this form from Socotra necessitates its transfer to Charaxes, since we now possess a species with the structure of the latter genus, and the general character of the supposed Philognoma. 1 Possibly owing to fading. |
