Show 66 ME. E. Y. WATSON ON THE HESPEEIID-E. [Ja«- 17, All the species of this genus in which the male has a tuft of hairs on the hind tibise also are provided with a " pair of scabbard-shaped scaly and hairy appendages, springing posteriorly from the breast at the base of the hind legs and about one third the length ot the abdomen." These appendages will be found to be present in the males of all genera which are provided with tufts on the hind tibise, and when the hind legs are drawn up the tuft is inserted between the appendage and the base of the abdomen. This is a genus which needs splitting up ; but a further knowledge of the earlier stages is necessary to do it satisfactorily. HESPERIA GERON, sp. nov. Upperside dark brown, almost black, spotted with white. Fore wing with a few grey scales at base of wing and along inner margin ; a longitudinal white spot at base of cell, a broad square spot extending across the centre of cell, and a crescent-shaped spot closing cell; an oval spot on submedian ; a submarginal row of eight white spots across wing beyond cell, the upper four coalescing, the first three large, the fourth small, the fifth triangular, equal in size to and immediately below the fourth, the sixth square, twice the size of the fifth, nearer the base of the wing, the seventh and eighth rectangular, almost equal in size, larger and nearer to the base of the wing than the sixth, the eighth placed immediately below the seventh, which is immediately below the crescent-shaped spot closing cell; a marginal row of eight white dots. Hind wing with a large rounded spot closing cell and three more spots coalescing with it and with each other extending towards the inner margin as far as the sub-median ; a small spot at base of cell and a marginal row of six white dots ; inner margin clothed with long whitish hairs; all above spots white. Cilia of both wings chequered. Underside : fore wing as above, the costal margin and apex suffused with greenish white; hind wing : ground-colour ochraceous yellow ; spots as above, but with an additional large spot in the marginal row, situated at the apex of the wing, and an extra spot in the discal row situated between the costal and subcostal nervures just above the subcostal bifurcation. Thorax and abdomen above black ; last few segments of abdomen whitish. Palpi and abdomen beneath greyish white. Antenna?: shaft grey above, white beneath ; club black, tip white. Expanse 31 millim. _ Nearest to II. phlomidis, H.-S., from which it differs in its smaller size, more extended white markings on the fore wing above, but chiefly in the colour and markings on the underside of the hind wing; in phlomidis the ground-colour is sap-green, in geron ochraceous yellow: in the former the large spot above the subcostal bifurcation unites with the discal row and also is broadly diffused above the costal nervure along the costa to the base ; in the latter the large spot above the subcostal bifurcation is well separated from the spot at end of cell and does not extend above the costal nervure. Described from six specimens collected by m e at Quetta, Biluch-lstan, in June. There ^ also a single specimen in the collection |
