UNDESCRIBED RHOPALOCERA IN THE BRITISH MUSEUM. 251 



increased in extent, in the fore wing reducing the black markings to 

 a narrowish band extending from base along costa and bind margin 

 into the extremity of area la, its inner edge very irregular throughout, 

 forming a broad tapering bar across the discocellulars, which fuses 

 with a triangular patch in the base of area 2, and a broad black 

 subapical bar enclosing an oval patch of yellow. The base of 

 the wing as far as the origin of vein 2 is suffused with pale orange. 

 In the hind wing the whole wing is lemon-yellow with the exception 

 of a narrow black border which extends as far as the anal lobe, 

 where it encloses the three silver spots, which are a good deal larger 

 than in the male. Underside, fore wing : x\s above, except that there 

 is no basal orange suffusion ; the cell is filled with black to a little 

 beyond the origin of vein 2, so that a yellow oblong spot is tints 

 enclosed in the cell; and that the band on the hind margin is narrower 

 than above, the difference in the corresponding widths being occupied, 

 in the apical area only, by white. Hind icing : Marginal band also 

 narrower than above, inwardly edged with white, terminating half- 

 way along costa with a wedge-shaped black mark directed towards 

 the extremity of vein 3, but barely reaching vein 7. A narrow 

 irregular black mark extends from base some slight distance along 

 vein 16, and beyond this is a series of three rather indefinite black 

 points in a curve, the uppermost on vein 3 at its origin, the others 

 one each on veins 2 and lb. The orange scaling of the male in the 

 abdominal region is represented only distally and faintly along vein 

 1& ; of the two silver bands of the male only the outer is present, 

 and extends as far as vein 2. 



The abdomen, thorax and palpi in both sexes orange below ; in 

 the male black like the wings above, slightly banded with yellow 

 laterally, in the female the head and thorax above are dark brown, 

 the abdomen conspicuously yellow banded laterally and dorsally, and 

 the thick tuft of hairs at the extremity of the abdomen grey.

The male agrees very well with Holland's figure of his nigra 

 (Ent, News, iv, pi. 1, fig. 9) and also with his description (Annals 

 and Mag. [6], x, p. 286) except as to colour. All the markings 

 here described as yellow appear to be white in nigra. Similarly 

 the female would do very well for antinmchus, Stand., were it \\ hite 

 instead of yellow. The probability seems to be that antimachus 

 nigra and spolia will all prove to be forms of the same species. 



Pseudaletis dardanella, sp. nov. 

 $. Upperside, both wings: Dead white, the hind margins and 

 cilia black. Fore wing : The costal area to just beyond end of cell, 

 the base of wing as far as the origin of vein 2, and the discocellulars, 

 all orange. The whole of the apical area black, the marginal band 

 decidedly broad, black, the inner edge of the continuous black area 

 thus formed very irregular and diffuse. Some slight orange suffusion 

 is also present against the marginal border on vein 1 and central!]
