Holland: Two New West African Rhopalocera. 15 



trochanters of the legs are clothed with white hairs, and thus reveal 

 three white spots on either side of the otherwise black lower side of 

 the thorax. There are also three small white tufts of hairs arranged 

 longitudinally on the last segment of the thorax dorsad the white 

 spot on the last trochanter. Upper side of wings: The ground-color 

 of the wings above is brownish-black, darkest on the cell and at the 

 base of the primaries, becoming lighter toward the outer margins, 

 and on the outer half of the secondaries passing into chocolate-brown. 

 The fore wing is ornamented by an interrupted median band of five 

 pale yellow spots, extending from the middle of the inner margin as 

 far as the fifth nervule. Of the spots composing this band the first 

 and the third are relatively narrow, the second and the fourth the 

 largest and suboval, the fifth a mere narrow streak. Beyond the 

 end of the cell near the costa there are two pale yellow subapical 

 spots, which are outwardly bifid, and only half as large as the corre- 

 sponding spots in the wing of P. ucalegon and P. ucalegonides. On 

 the hind wings the median band of spots is continued across the 

 wing to the middle of the inner margin, where it is widest. On this 

 wing the band is not interrupted, or broken, and changes in color as 

 it approaches the inner margin from pale yellow to grayish-white. 

 The hind marginal fold is densely clothed with long hairs and andro- 

 conia. The outer half of the hind wing is chocolate-brown, upon 

 which the black veins stand forth conspicuously, as well as the long 

 black rays which run from the outer margin to the median band 

 at the middle of each interspace. The fringes are concolorous, 

 without any trace of marginal white lunettes, as in some other species 

 of this group. Under side of wings: Both wings are much paler 

 below than on the upper side, being pale chocolate-brown, shading 

 at the base of both wings, and on the inner margin of the secondaries 

 into reddish. The spots of the upper side reappear faintly on the 

 lower side, and are not as well-defined as upon the upper surface. 

 The hind wing has two small black spots at the base, one at the origin 

 of the cell pupilled with white, the other at the origin of the precostal 

 vein solidly black. Expanse, as spread, 80 mm. The type, which is 

 unique, was taken in the vicinity of Lolodorf, Cameroon. 



I name the species in honor of its discoverer, Rev. H. L. Weber, 

 who in recent years has added many new and interesting species to 

 the African collections of the Carnegie Museum. The type, which is 

 unique, is in the Carnegie Museum.
