The distinctive mark of N. wahlbergii is the two dorsal groups of bright yellow fungoid 

 warts, four or five to eight or nine hi a group, and of irregular oval or polygonal shape; between 

 the dorsal and supraspiracular spines on abdominal segments 1 to 7 the spots are largest 

 on segments 4 to 6; on the eighth segment there are only one or two on one side. 



The median "horn" or tubercle is just as in N. dione, being split down or forked in the same 

 manner. Two examples from Durban, March, 1901. J. M. Fawcett.

Imago. — One <? . Head as usual in Nudaurelia; front broad, square toward the labial 

 region; surface full, convex. No trace of tongue. Antennae of $ dark, almost black, sub- 

 plumose, bepectinate, 16 double sets of branches, tip suhfiliform, the nine terminal joints with 

 seven to eight pairs of rather long vestigial branches. Palpi stout, reaching the front, but not 

 passing beyond it; third joint small, distinct, not so long as the. second joint is broad. Thorax 

 with the vestiture moderately shaggy; greenish yellow with whitish roseate hairs. 



Fore wings falcate, of the same shape, but a little less acute at the apex than in N. anthina: 

 wings of both pairs yellowish olive green with hoary lilac shades. Basal line narrow, dark, 

 differing from that of N. anthina in being straight instead of zigzag, with a slight bend or dis- 

 location on the median vein; beyond this a broad lilac hoary shade, expanding along the third 

 median vein (IV 2 ), and again toward the discal spot. Extradiscal line as in N. anthina, a 

 double narrow dark line mixed with yellow, whitish between the two lines; costal end of lin6 

 toothed [?] on both sides and to the apex with hoary lilac. Beyond is a pale lilac broad shade 

 extending externally (as in N. anthina, but more distinctly) ; seven sharp triangular points or 

 scallops. Discal clear spot small triangular, with no ring or aureole around it- 

 Hind wings concolorous with the fore wings; the basal white band bent toward the inner 

 edge of the wing as in N. anthina, and shaded in the middle with brown both inside of the white 

 line, and outside between it and the discal ocellus. Extradiscal line white, curved outward as in N. 

 anthina, shaded externally toward the costal edge with brown and also inside toward the ocellus; 

 beyond is a zigzag line of five or six pale lilac scallops. Discal ocellus large, almost perfectly 

 round (13 x 12 mm.); a clear central round space inclosed by a deep ochreous ring, then a dark 

 brown ring not so wide as in N. anthina, and outside is a pale tawiy ring edged toward the costal 

 side with white. Costal region as far as the discal spot, deep reddish salmon. 



Wings beneath hoary gray, especially those of the hinder pah; the discal clear spot on the 

 fore wings as above, but no ocellus or any spot on the hind wings. Extradiscal line common to 

 both wings, but fainter than above. A submarginal series of about eight hoary lilac points as 

 above. Edge of both wings greenish yellow. 



Expanse of fore wings, S 110 mm. 



Length of fore Aving, s 59 mm. 



Breadth of fore wing, s 30 mm. 



Length of hind wing, <? 37 mm. 



Breadth of hind wing, <? 29 mm. 

 Differs from N. anthina in its olive-yellow green hue, in the basal line being straight, not 

 zigzag, in the reduced discal spot, having no yellow ring around it, and in having no discal spot 

 on the under side of the hind wings, when in N. anthina one is present on each wing. 



It agrees with Sonthonnax's figure (from a photograph) of "B. intermiscens." The original 

 type of intermiscens is in the Strecker collection, as I was told by Mr. Strecker himself . 



Mr. Rothschild states that Walker's B. intermiscens is a synonym of his B. rhodo2)hila. My 

 specimen is in the Schaus collection hi the American Museum of Natural History. 



Geographical distribution. — Congo, Cameroons, West Africa (Sonthonnax), Calabar.
