. Bulletin of the British Museum (Natural History) Entom Supp. 140 Wing shape. This varies from species to species. In the $ fore wing the inner margin is hardly lobed at all in sidus, mimosae, tajoraca, aphnaeoides, flavilinea, alienus, aemulus and penningtoni ; the lobe is more pronounced in the other species, especially in those of the iasis and hemicyanus groups. In most of the species the fore wings are roughly of the subtriangular shape, but in the hemicyanus group the inner margin is much shorter than the costal margin so that the wing becomes almond-shaped. The hind margin

In the $ fore wing the inner margin is hardly lobed at all in sidus, mimosae, tajoraca, aphnaeoides, flavilinea, alienus, aemulus and penningtoni ; the lobe is more pronounced in the other species, especially in those of the iasis and hemicyanus groups. In most of the species the fore wings are roughly of the subtriangular shape, but in the hemicyanus group the inner margin is much shorter than the costal margin so that the wing becomes almond-shaped. The hind margin of the hind wings is slightly concave in alienus, violacea and bakeri ; on the other hand in the other species it is angled or even tailed at the end of vein 3, this tail being moderately well developed in the laon group. There is a delicate tail at the end of vein 2, and another longer one at vein ib which in longicauda is very long. Male secondary sexual characters : on the underside of the fore-wings there is a glossy area, between the lower edge of the cell and the inner margin, which is small or even absent in some species, mimosae, aphnaeoides, alienus, aemulus and bellina, but large and conspicuous in sidus, iasis, cytaeis, laon, silanus, australis, creta etc. A hair tuft on the inner margin is present in all species except glaucus and those of the hemicyanus group. On the upperside of the hind wing, in all the species of the subgenus, there is a more or less well developed glossy androconial patch at the base of the wing. Wing venation (Text-fig. 297). Fore wing with 11 veins in both sexes. Male genitalia (Text-fig. 125, sidus). Uncus composed of two small triangular lobes narrowlv fused to the margin of the tegumen on either side of the median depression ; subunci long, robust, massive basally, obtuse angled, blunt ended ; tegumen strap-like, its posterior margin with a rounded depression ; as in all lolaus, the tegumen in its normal position is hood-shaped ; vinc
