Imago. — One s . Ground color of the body and wings ocher- yellow ; collar, breast, and 

 all the legs sable brown. Head at base of the antennae white; tegulse white, thorax and 

 abdomen yellow. 



Fore wings with six cross lines; yellow with a broad diffuse pink shade, beyond which is 

 a narrow four-scalloped brown line most distinct hi the discal space; a doubly scalloped narrow 

 dark line just beyond the discal spot, each scallop divided into sharp secondary ones. About 

 half way between the discal spot and edge of the wing is a fine dark brown line, not scalloped, 

 and paradel with the outer edge. The outer margin of the wing is broadly lined with dull 

 lilac and incloses a yellow seven-scalloped line, the points of the scallops thicker, and the apex 

 of the wing yellow. 



The discal spot about one-third as large as that on the hind wings, roundish oval, the 

 center clear, crescentiform, minute, edged externally with black scales; the outer portion of 

 the spot pale reddish, encircled with deeper red. 



Hind wings yellow, the yellow and dark lines nearly repeating those of the fore wings. 

 Discal spot large, reddish, the center black, not clear, D-shaped; a lilac circle between the 

 inner paler red and the outer deep venetian-red circle. 



The extradiscal line is narrow and nine-scalloped; the scallops largest and most marked 

 toward the inner edge. Between the discal spot and the inner edge are two unequally zigzag 

 brown lines. 



Beneath, the wings are as above, though of a faded hue, and the lines fainter. Discal 

 spot of fore wings about half as large as above and nearly as large as the discal spot of the 

 wings of the hinder pair, the latter being centered by a short black line. 

 Expanse of the fore wings, <? 130 mm. 

 Length of a fore whig, s 60 mm. 

 Breadth of a fore wing, s 34 mm. 

 Length of a hind wing, s 40 mm. 

 Breadth of a hind wing, J 32 mm. 



Geographical distribution. — Nearly the entire Ethiopian realm. Westwood gives the 

 following localities: Ashantee, Sierra Leone, and Port Natal. The specimen from which my 

 description was drawn up was sent me by Mr. J. T. Queckett from Durban, Natal, the moth 

 having appeared in November, 1901. 



Mr. Rothschild gives the name fusca to an aberrant specimen from Natal which has the 

 ground color reddish chestnut instead of yellow. He adds: "Sierra Leone specimens of the 

 female are much brighter, and the patterns are more distinct than Natal specimens, while 

 Sierra Leone males are paler in color and the markings more restricted." 



Subfamily 4. Cyetogonin^; Packard. [Micragonin-e.] 

 [Cyrtogoniinse Packard, Psyche, February, 1902, p. 306.] 



[The original diagnosis is as follows:] 



Antennae of <? with a single pair of pectinations to a joint, in venation differing from that 

 of the other groups, in veins II U H 2 , and II 4 [HI., etc., in revised nomenclature] of the fore 

 wings all originating at nearly the same point, quite far beyond the outer end of the discal
