Imago. — One <? , one 9 . Antennae of J well pectinated, only slightly subplumose, with 

 27 to 28 joints, and the branches well ciliated; the tip subfiliform, consisting of 10 joints, the 

 external vestigial branches of the tip longer than the inner, and well developed, and about as 

 long as the joints themselves. Antennas wanting in my 9 . Head fairly prominent; the 

 front not very convex, only moderately wide; the vestiture close. Palpi large, stout, porrect, 

 well developed, and extending a little beyond the front; third joint fairly well developed, 

 unusually distinct from the second. 



Body and wings Vandyke brown; collar and tegulas faintly edged with whitish scales. 

 Fore wings distinctly falcate ; the costa much arched and the apex unusually sharp in <? , 

 more so than in N. dione; outer edge deeply and regularly excavated ; inner angle well rounded. 

 Hind wings with the costa very convex, apex squarish ; outer edge moderately convex. Abdomen 

 not reaching to the inner angle or very near it. Wings of both pairs uniformly pale rich Vandyke 

 brown. Fore wings with the basal line faint, obsolete. Extradiscal line straight, not sinuous 

 or scalloped, arising from the outer third of the inner edge and ending on the costa before the 

 apex in a hoary cloud; the line is blackish, edged within with whitish. Discal spot small, 

 subtriangular or D shaped, the outer side rounded, surrounded by a faint dark line, not forming 

 a distinct circle. Hind wings like the fore wings, but with a roseate shade on the costal region, 

 winch does not reach the apex; extradiscal line dark, diffuse, whitish within, curved outward 

 and nearly touching the discal spot, which is large, black-brown, with a small round clear area 

 in the center, encircled with snuff brown; while the outer circle is very pale Vandyke brown, 

 paler than the rest of the wing; the basal line in 9 white, distinct, more so than in the <? . 



Fore wings beneath as above, but more hoary along the extradiscal line; along the inner 

 edge roseate. Hind wings with the ocellus only a clear spot, smaller than on the fore wings. 

 Extradiscal shade faint, slightly marked, not curved, not roseate beneath. The 9 only differs 

 in having a diffuse broad hoary shade beyond the extradiscal line above and beneath. 



Expanse of fore wings, S 95 mm.; $ 122 mm. 



Length of a fore wing, <? 50 mm.; 9 70 mm. 



Breadth of a fore wing, S 25 mm. ; 9 38 mm. 



Length of a hind wing, S 32 mm. ; 9 48 mm. 



Breadth of a hind wing, s 25 mm. ; 9 33 mm. 

 That this species is not a Bunaea, to which it has been referred by Druce, Aurivillius, 

 Rothschild, and Southonnax, but a true Nudaurelia, is shown by the venation, which is almost 

 exactly as in N. dione and rhodophila, as may be seen on reference to Plate XXXVII, Figures 

 1 and 2. Veins IIj and II 2 and II 3 are well developed and the origin of the median branches 

 are almost identical. The unusually falcate S wings, the pointed apex, the small triangular 

 clear discal spot, without an aureole around it, give it an appearance, not so much like Bunaea, 

 as we have restricted that genus, as of a species of Lobobunaea or Gonimbrasia. 



Geographical distribution. — West Africa, Sierra Leone (Schaus collection, Amer. Mus.

NUDAURELIA AURANTIACA Rothschild. 



Nudaurelia aurantiaca Rothschild, Nov. Zool., II, p. 42, 1895. 



Imago. — "Fore wings deep ruddy orange; about one-third from the base they are crossed 

 transversely by a double zigzag line from the costa to the inner margin; on the inner side this 

 double band is black, and in the outer white. At the apex of the cell there is an ocellus sur- 

 rounded by a black outer ring, center vitreous with a broad fuscous inner ring. A little beyond
