New Species and Subspecies of Pierinae. 13 



panies the inner side of the median trunk and first median branch, 

 but leaves free the greater part of the course of the submedian vein. 

 In the angle between the median trunk and the first median branch, 

 it passes into a curved band which takes its course round the end of 

 the cell, turns forward, and becomes lost on the lower aspect of 

 the second subcostal. The fuscous shade is somewhat deeper just 

 anteriorly to the third median branch than elsewhere, but it does 

 not form a definite spot. A much paler fuscous infusion forms a 

 broad marginal shading to the wing. There is a minute dark fuscous 

 spot on the lower discocellular, close to the origin of the radial ; 

 the costa is edged with rich orange, prolonged along the margin 

 as a narrowing streak as far as the end of the first subcostal. A spot 

 of the same colour occupies the root of the subcostal at its junction 

 with the body. 



$. Exp. al. 52 mm. (Another $ measures 54 mm.) Upper- 

 side white tinged with greenish yellow. Fore-wing with a slight 

 duskiness along the costa, which opposite the end of the cell passes 

 into a definite dark streak reaching to the apex. The extremities 

 of the veins along the hind margin marked, as in the male, with 

 fuscous spots; these diminish from before backwards; no spot on 

 the submedian vem. A dark fuscotis spot, larger than in the male, 

 occupies nearly the whole of the lower discocellular vein ; and dark 

 discal spots, similar in character and situation to those on the lower 

 surface in the male, but more pronounced, occur in connection with 

 the second and third median branches. The series is continued by 

 another smaller spot uitemal to the first median branch. Hind- 

 wing immaculate except for a minute dark spot on the lower 

 discocellular vein. 



Beneath, the fore-wings are white, tinged with the same greenish 

 yellow as on the upper surface ; but even paler, especially towards 

 the inner margin. The apical area is ochre yellow dusted with 

 yellowish brown. The same brownish dustmg is continued inwardly 

 as an ill-defined streak along the costa, but dies out before reaching 

 the body. Within the apical area it collects chiefly at the marginal 

 ends of the veins, forming indistinct spots which are prolonged as a 

 diminishing series as far as the termination of the first median. A 

 further condensation of brownish or fuscous scales forms a patch 

 at the inner end of the apical area where this meets the costa. This 

 patch is in series with dark discal spots occupying corresponding 

 situations with those on the upper surface; the last of them is 

 marked only by a few brown scales. A dark oval spot, larger 

 than the corresponding spot on the upper surface, occupies the 

 lower discocellular vein. The ground-colour of the hind-wings 

 is the same as that of the apical area of the fore-wings, viz.
