Show 366 MR. H. H. DRUCE O N T H E [June 2, rather broadly and evenly bordered with brown, down the centre of which is a marginal row of large black lunules, indistinctly bordered inwardly with whitish and outwardly with distinct white spots, some of which appear slightly bluish. Head, thorax, and abdomen blackish above, white beneath. Expanse If inch. Florida I. I have before me three males of this beautiful species, which is allied to E. inops, Feld., from Aru ; but it appears to be of a more brilliant shade of blue than specimens of that species, and on the underside is distinguished by being entirely without the broad brown border to the costal margin of fore wing, and the brown ultra-median band to the hind wing. PROSOTAS, gen. nov. Allied to Nacaduba and allied genera, from which it differs by having the first branch of the subcostal nervure very short, reaching only to the costal nervure, which it joins, and disappears. Type P. caliginosa, mihi. PROSOTAS CALIGINOSA, sp. n. (Plate XXXI. fig. 15, 6 •) Male. Upperside dark greyish brown, rather darker at the margins ; slightly shining violaceous in the disks, especially of the hind wing; cilia light brown. Underside dark brownish grey, with bands and lunules edged with sordid white, much as in N. ardates, Moore, but having the submarginal row of lunules on both wings large, indistinct, and darker thau any other portions of the wing. On the hind wing, near the anal angle, is a large black spot inwardly edged with orange. Female. Upperside uniform dull greyish brown, of a lighter shade than male. Underside as in male but paler. Head, thorax, and abdomen brownish ; legs brown with small white spots ; antennae brown annulated with white. Expanse f inch, 6 2 • Alu I., near Shortland I. Aola, Guadalcanar I. Rubiana I. Malaita I. I have compared this species to N. ardates, Moore, but on the upperside it has a very different appearance, somewhat resembling some specimens of the European Lyccena alsus. It is possible that this is the Lyccena cdsulus, Herr.-Schaff., but it does not seem to fit the description. Lyccena biocellata, Felder, from Australia, possibly belongs to this genus, but I have no specimen for examination. JAMIDES, Hiibn. J A M IDES A M A R A U G E , sp. n.
