then there is no longer any doubt of the identity of Nais and 

 Phalerata. 



With regard to A Decorata, I cannot as yet say as much. I 

 have for some time regarded this as a form of Nais, but this sea- 

 son I have reared it from the larva, and found that it differs from the 

 larva from which Nais wa.s raised, as the following brief description 

 of larva of A Decorata when full grown will show : It is black, 

 rather thick, ten tubercles bearing clusters of hairs to each seg- 

 ment, the second and third on each side from above dark orange 

 of rather a smoky hue, the tips black. Part of the hairs on the 

 sides and all of those on joint l, top as well as sides, are brown, 

 the rest are black. Stigmata bright orange; no dorsal line. 

 From this it may be seen that the identity of this with the others 

 is a subject for future investigation. 



TWO NEW SPECIES OF THANAOS. 



By W. H. Edwards. 



Thanaos Tatius. 



Male. — Expands 1.6 inch. 



Upper side of primaries umber-brown, blackish on disk and 

 to base, the outer limb free from white scales; on outer edge of 

 disk towards costa a light brown patch ; on costa four sub-apical 

 silvery dots, in zigzag line ; one such dot in upper median inter- 

 space, and one, rather obscure, against end of cell ; along hind 

 margin a row of small patches of bluish-white scales ; the usual 

 (in this genus) extra-discal band is made up of large lanceolate 

 and elongated black spots, separated, each edged on the outer 

 sides by bluish-white scales, which scales form a conspicuous 

 serrated line across the wing. 



Secondaries black-brown with an indistinct series of lighter 

 patches beyond the disk ; fringes of primaries concolored ; of 

 secondaries white, cinereous at outer angle. 



Under side of primaries lighter, the spots repeated, the one 

 against cell distinct ; along hind margin a row of white points, 

 and at inner angle a white patch ; beyond the disk an indistinct 

 series of whitish patches, almost obsolete in the middle of the 

 wing; the apical area dusted white. Secondaries uniform blackish- 

 brown ; along the edge of hind margin a macular white band, 

 represented by dots on the upper half. 



Body above dark brown, beneath same, but the thorax with 

 many dark grey hairs ; legs dark brown ; palpi brown with dull 

 white hairs interspersed ; antennae black, on the underside ringed 

 white ; club black above, the under side and tip ferruginous. 



From a single male. 



This fine species is readily distinguished from any of the
