Platytliyris fasciata, n. s. 



(Plate 13, figs. 4, $ , 5, $ [reverse].) 



Dull cupreous brown. Anterior wings with three approximate, 

 wide, diffuse, transverse basal bands, composed of obscure yellow 

 scales, speckled with and separated by brown scales of a brighter 

 hue than the ground color of the wings. The first of these bands 

 covers the extreme base of the wing and is so diffuse as to lose its 

 vittate character. All of these bands are brighter and more dis- 

 tinctly marked on costa ; the third, which crosses the disc, is most 

 evident. Impinging on the outer margin of the third band is a 

 small, sub-triangulate, vitreous spot on the disc. Beyond, the dull 

 brown color of the wing obtains, appearing as a regular band 

 tapering to internal margin. Beyond this are two terminal bands 

 similar to the basal ones but darker, more brownish, and more dis- 

 tinctly defined and separated. The first of these, or the subter- 

 minal band, is contiguous to the second or external band, which 

 latter lies directly on the margin. Secondaries, resembling prima- 

 ries in appearance and coloration. The yellowish bands of the 

 primaries are here in reality continued, but are so diffused that the 

 surface of the wings appears to be irregularly mottled with yellow 

 and bright brown scales. A much larger vitreous discal spot than 

 that on the primaries, acutely excavate externally. Fringes, brown- 

 ish, paler at the incisures of the margin. 



Under surface, pale brownish, faintly mottled and lined, con- 

 trasting rather forcibly with the upper surface in general color. On 

 the primaries are four distinct blackish olivaceous transverse bands. 

 The first, at just beyond the base, is little more than a faint linear 

 streak ; the second, is wider, darker, especially on the disc, and 

 interrupted, not attaining internal margin ; the third is very wide, 

 broadest (with the first two) on costa, with sinuate borders, taper- 

 ing towards internal margin, immediately on which it again 

 expands. Impinging on the inner margin of this band is the discal 

 vitreous spot, which, with that on the secondaries, is the same on 

 either surface. The fourth band is broad and runs along external
