390 Mr. Butler's descriptions of Lepidoptera- 



12. Acritocera negligens, n. s. 



Primaries brown, the veins slenderly blackish, 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.

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 slightly greyish, preceded by a marginal series of black 

 points ; secondaries semitransparent 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 

 tegulse; primaries below with marginal black dots and greyish 

 fringe, otherwise without markings; secondaries with six inter- 

 nervular marginal black dots ; antennae below ochraceous. Expanse
