Show 189L] VYCMNIDM OF THE SOLOMON ISLANDS. 365 M. Semper and others ; but on the underside it is a brilliant metallic golden yellow, which is not shown in Felder's figure. THYSONOTIS CHROMIA, sp. n. (Plate XXXII. fig. 3.) Male. Upperside silky violaceous blue, costa and outer margins very narrowly and evenly black ; cilia black ; tail black, tipped with white. Underside : fore wing creamy white, with the costal margin broadly black ; outer margin narrowly black near apex, gradually widening towards outer angle; an indistinct marginal whitish line, and a distinct submarginal white line thickening at each nervule. Hind wing : costa pure white from the base, gradually tapering towards the apex; below that a broad black band between the costal and subcostal nervures reaching from the base to the apex ; below this a broad white band from the inner margin running to a point at the apex, even on its upper edge, zigzag on its lower; following this a rather broad black band, and again beyond this a submarginal row of black lunules bordered inwardly with large white crescent-shaped lunules ; the four lower ones being more or less covered with brilliant shining ceerulean-blue scales. A rather broad distinct white marginal line from the apex to the anal angle, intercepted with black at each nervule. Head, thorax, and abdomen concolorous with wings ; antennae black, annulated with white ; legs black and white. Expanse lyV inch. Fauro I. Maravo I. I have not seen the female of this insect. It is allied to T. sper-chius, Feld., but has many points of distinction. The specimen figured is from Fauro I. EPIMASTIDIA, gen. nov. Allied to Thysonotis; neuration the same ; antennas somewhat more slender and more gradually clavate. Upperside of hind wing with subcostal nervure clothed from base for about two-thirds its length with long slender hairs. Underside with no metallic spots or markings. Type Lyccena inops, Feld. In the British Museum collection E. inops is placed in the genus Pithecops, with which it also agrees in neuration, but I think from its general appearance it is more nearly allied to Thysonotis. It may perhaps be found convenient to retain the name Danis for the group of which the Papilio danis, Cr., is the type, as they seem to be coarser-scaled aud more robust insects. Epimastidia contains tailless insects, Thysonotis tailed and tailless, and Danis tailless species. EPIMASTIDIA ARIENIS, sp. n. (Plate XXXII. fig. 6.) Male. Upperside uniform shining caerulean blue, with the outer margins of both wings rather narrowly blackish brown ; hind wing with the costal third whitish brown, lighter towards the margin. Underside pure creamy white, with the outer margins of both wings PROC. ZOOL. Soc-1891, No. XXV. 25 |
