16 MR,. 0. V. A. PEEL AND OTHERS ON [Jan. 23, 



Ve i ns : — in the fore wing the 2nd and 3rd subcostal, the two radial 

 and the three median branches; in the hind Aving the 2nd subcostal, 

 the radial, and the three median. These marginal spots are oval 

 in the hind wing, the long axis being parallel with the border of 

 the wing ; in the fore wing they are more or less triangular, with 

 their bases at the margin. The first two at the apex of the fore 

 wing are more or less fused ; the remainder in both wings are 

 distinct. There is a slight submarginal powdering of black scales 

 in the fore wing between the 2nd and 3rd subcostal, and also 

 between the two radials. A much fainter powdering occurs 

 between the 3rd subcostal and upper radial, and the slightest 

 possible trace of a similar powdering between the 2nd and 3rd 

 median. The marginal spots and the submarginal powdering mark 

 out between them a very indistiuct series of white subapical spots, 

 the first three more or less wedge-shaped, the fourth nearly 

 circular ; these are barely to be separated from the general white 

 surface. Beneath, the wings are white ; there is a thin dusky line 

 along the costa of the fore wing, and dark marginal spots, like 

 those of the upper surface but smaller, occur at the extremities of 

 the same veins in both wings. There is an orange-yellow patch at 

 the base of the fore wing, occupying about one-fifth of the cell, and 

 somewhat prolonged along the course of the subcostal vein. The 

 same orange-yellow colour occurs in the hind wing as a streak along 

 the costa, as a well-defined patch between the roots of the median 

 and submedian veins, and as a median chain of spots crossing the 

 disc of the wing from the costa to the inner border ; these latter 

 are seven in number, one occupying each interspace posterior to 

 the costal vein except the space between the second subcostal and 

 discoidal, and that between the second and third median. The 

 third of the series surrounds the discocellular venule. This and 

 the four succeeding spots are fairly distinct ; the other two are 

 faint. There is also a very slight indication of a submarginal 

 series of dull yellow spots running parallel with the hind border 

 of the wing. 



Female. Above, like the male, but with the marginal dark spots 

 somewhat larger. These are triangular in the hind wing, and in 

 the fore wing become fused towards the apex into a narrow marginal 

 band. The dark subapical powdering forms more definite and 

 larger patches than in the male, and the white subapical spots are 

 consequently more distinct. There is a trace of a marginal dark 

 spot at the termination of the submedian vein of the fore wing, 

 which is hardly if at all visible in the male. The basal pearly 

 gloss is well marked, and the basal orange-yellow shows slightly 

 through from the lower surface. Beneath, as in the male ; but the 

 basal orange-yellow occupies from one-third to one-half of the cell 

 instead of only one-fifth. The submarginal series of spots is some- 

 what more distinct than in the male, aud appears to be of the same 

 orange-yellow as the median series. 



In both sexes the first subcostal branch of the fore wing coalesces 

 with the costal. The wings of the male are slightly more pointed,
