Antennse : club moderate, evenly curved. Palpi porrect; third joint short, obtusely conical. Fore wing: inner margin longer than outer margin ; cell less than two-thirds the length of costa ; vein 12 reaching costa almost opposite end of cell; discocellulars slightly inwardly oblique, the lower the longer ; vein 3 shortly before end of cell ; vein 2 twice as far from end of cell as from base of wing. Hind wing evenly rounded ; vein 7 very close to end of cell ; discocellulars and vein 5 barely traceable; vein 2 immediately before end of cell ; vein 3 considerably nearer to end of cell than to base of wing. Male : no costal fold on fore wing, but with a large patch of appressed scales on the upperside of the hind wing, occupying the basal half of the wing from the costa to the middle of cell. The inner margin of the fore wing on the underside is also clothed with modified scales, presenting a silky appearance, and bearing a tuft of hairs attached to the submedian near the base. The hind tibise are flattened, and bear a tuft of hairs attached along their inner surface. There are three species of this genus in the British Museum from W. Africa, two being unidentified, and the third being pulvina, Plotz. All these three species present slight modifications in the extent of the sexual patches on both wings, and in pulvina the hind tibise are only fringed, and exhibit no trace of the tibial tuft. 17. Genus TAGIADES. (Plates I. fig. 9 ; III. fig. 11.) Tagiades, Hiibner, Verz. p. 108 (1816). Type, japetus Cram. Pterygospidea, Wallgr. Rhop. Caffr. p. 53 (1857).' Type, flesus, Fabr. Antennse: club slender, bent at about a right angle, terminal portion rather long. Palpi porrect, third joint minute. Fore wing: inner and outer margins subequal; cell less than two-thirds the length of costa; vein 12 reaching costa well before end of cell; discocellulars suberect, the lower the longer ; vein 3 shortly before end of cell, three times as far from 2 as from 4; vein 2 almost twice as far from end of cell as from base of wing ; lower margin of cell between origins of veins 2 and 3 strongly arched. Hind wing evenly rounded ; vein 7 well before the end of cell, about twice as far from 8 as from 6 ; discocellulars and vein 5 very faint ; vein 3 shortly before end of cell, twice as far from 2 as from 4; vein 2 considerably nearer to end of cell than to base of wing. Hind tibise fringed, and with two pairs of spurs. It is quite impracticable to separate Pterygospidea from Tagiades, the only difference being that in flesus the outer margin of the fore wing is slightly excavated just above the outer angle, which is not the case in japetus ; when, however, one tries to apply this |
