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.

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 Nacaduha 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 caltginosa, sp. n. (Plate XXXI. fig. 15, S .) 



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 than 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.

T 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 alsulus, Herr.-Schaff., but it 

 does not seem to fit the description. 



Lyccena biocellata, Yelder, from Australia, possibly belongs to 

 this genus, but I have no specimen for examination.

Jamides amarauge, sp. n, (Plate XXXI. figs. 20 d* , 21 $ .) 



Male. Upperside brilliant shining silvery light blue, greenish in 

 some lights ; primaries with apex and outer margin broadly blackish 

 brown ; secondaries with the outer margin brown-bordered and a
