I. TWO NEW WEST AFRICAN RHOPALOCERA. 

 By W. J. Holland. 



(Plate IV.) 



While recently restudying and labelling the Papilionidce of Africa 

 in our collections, I came across a specimen, which I am unable to 

 refer to any species known to me in nature, or described and figured 

 in any of the literature accessible to me. It comes nearest to Papilio 

 ucalegonides Staudinger, of which specimens are before me as I write, 

 but differs from that species, in having the median band of light 

 spots on the fore wing widely interrupted, in not having a large 

 whitish spot at the lower outer angle of the cell of the fore wing, and 

 in having a series of submarginal spots in both fore and hind wings. 

 In addition on the lower side of the wings the markings are much less 

 clearly defined than in P. ucalegonides, though the light spots of the 

 upper side reappear faintly on the lower side, including the sub- 

 marginal spots, and the spots at the base of the hind wings are but 

 two, whereas in P. ucalegonides, there are three. The figures I give 

 will enable students to recognize this form. I append a detailed 

 description.

Antennae, palpi, head, thorax, legs, dorsal region and sides of 

 abdomen as far down as the spiracles, black, except that above each 

 spiracle there is a sublunulate yellowish-white spot, with its longer 

 axis running diagonally from below upward and backward. Below 

 this series of spots there is a narrow longitudinal yellow line, running 

 the length of the abdomen, which is succeeded ventrad by a more or 

 less broken longitudinal line of black spots, which are largest upon 

 the anterior segments. The middle of the abdomen on the under 

 side is orange-yellow throughout, save that the first two segments 

 are each marked with a small black annulus or circle on the median 

 line. Minute spots, composed of tufts of white hair-like scales, are 

 located, one below, one in front of, and one behind each eye. The
