The wings are crenulate, slightly concave about the middle of the margin of the 

 primaries and truncated at their lower angle thus resembling in outline the wings of 

 C. sangaris, which is a much larger species. The hind wings are somewhat produced 

 at the anal angle, but not more so than is the case in C. aramis and C. anatorgis. 

 Both wings are defined outwardly by verj' fine black lines, except on their inner 

 margins; both have a submarginal series of quite small black dots on the inter- 

 spaces, those of the foie wing tending in a number of specimens before me to become 

 obsolete, those on the hind wings, which are larger and more conspicuous than those 

 of the fore wings, in some specimens tending to become arcuate or sagittate toward 

 the anal angle. 



9 . The female in general appearance is not unlike the female of C. ogova 

 (Ploetz), but the white transverse band on the upper side of the secondaries lies much 

 nearer the base than in that species, and the dark basal area, which succeeds it in- 

 wardly is correspondingly reduced in extent. The differences between the two sexes 

 as shown by the upper side of the wings is clearly revealed in the figures given upon 

 Plate X.

There are thirteen males and two female.? of this beautiful species in 

 the collection. They were all taken at Medje (type locality) in July and 

 August, except one male which is labelled as caught at Niangara in 

 November. 



On the occasion of the visit to the Carnegie Institute by their 

 Majesties, the King and the Queen of the Belgians, and of His Royal 

 Highness, the Crown Prince Leopold, Duke of Brabant, on October 23, 

 1919, I had the honor of showing to Her Majesty, the Queen, a proof of 

 Plate X of this paper, which was lying upon my desk. I requested Her 

 IVIajesty to accord to me the privilege of naming this loveh^ butterfly 

 in her honor, and 'she most graciously acceded to mj' request, expressing 

 pleasure at the thought. It therefore bears the name of the Queen of the 

 Belgians. 



The types are in The American Museum of Natural History; 

 paratypes in the Holland Collection.

The male of this species has never hitherto been described or figured. 

 I possess a series of eighteen males and twenty-two females bred for me 

 more than twenty years ago by Dr. A. C. Good at Kangve on the Ogove 

 River. On Plate X, Fig. 3, 1 give a figure of the upper side of the wings of 

 the male and in Fig. 4 a representation of the wings of the female. The 

 male has a small shining white spot, girdled with black, at the very base
