390 Mr. Butler's descriptions of Lepidoptera- 



12. Acritocera negligens, n. s. 



Primaries brown, the veins slenderly blaelvish, the whole of the 

 internervular areoles longitudinally streaked with blackish and 

 dark brown ; an oblique pale testaceous stripe beyond the middle ; 

 secondaries pale brown ; body brown, head and antennae whitish, 

 palpi with blackish terminal joint; wings below pale brown, 

 irregularly mottled with patches of dark brown scales. Expanse 

 of wings, 41 mm. 



Viti Islands. 



The character of the antennge in this species is so 

 peculiar that it at once arrests the attention ; in some 

 respects it resembles that of Ereiixa {Amphidasijidoi),

 and is confined to one side of the shaft. 



LEUCANIIDiE. 

 Leucania, Ochs. 



13. Leucania diatrecta, n. s. 



Pale creamy stone-colour; primaries above with a brown 

 <-shaped marking at base, its upper fork resting upon the median 

 vein, irrorated with black scales, and forming the commencement 

 of a slender dusky median streak, which extends beyond the cell 

 almost to the middle of the disc, but is interrupted at the inferior 

 angle of the cell by a black and white dot ; a slender blackish 

 streak along the internal margin, but not extending to the base ; 

 fringe shghtly greyish, preceded by a marginal series of black 

 points ; secondaries semitrauspareut sericeous-white, with ill- 

 defined greyish apical external border and fringe, tapering towards 

 the first median branch, where it ceases ; a white line at the base 

 of the fringe ; a short blackish streak on the inner fringe of the 

 tegulffi ; primaries below with marginal black dots and greyish 

 fringe, otherwise without markings ; secondaries with six inter- 

 nervular marginal black dots ; antennie below ochraceous. Expanse 

 of wings, 29 mm.
