but somewhat densely overlaid along the costal margin, on 

 apical area of fore wing and over the whole surface of the hind 

 wing, with a dusting of black scales that gives the underside of 

 the wings a decidedly green tinge. Antennae, head, thorax and 

 abdomen as in hi/ale, but the latter two somewhat darker on the 

 upperside. $ . Upperside: ground-colour apparently always white, 

 but so very densely overlaid on the basal third of the fore and 

 over the whole surface of the hind wing with irrorations of black 

 scales, that the insect has a very distinctive appearance when 

 compared with the white dimorphic $ of liyale black borders to 

 both wings as in hyale, but traversed on the fore wing by only 

 two white spots and on both wings proportionately broader. 

 Underside : fore wing white, apex broadly greenish yellow ; disco- 

 cellular and postdiscal spots as in hyale. Hind wing : greenish 

 yellow, spots and markings much as in hyale. Both sexes always 

 run strikingly smaller than they do in the tvpical form.

c? . Upperside : bright sulphur-yellow. Fore wing : extreme 

 base irrorated with a small patch of black scales ; a black disco- 

 cellular spot ; the terminal fourth of wing evenly black from costa 

 to dorsum, the inner margin of the black area curved and not 

 sharply defined, the middle of the area traversed by a series of 

 large, somewhat oval, yellow spots, beyond which right to the 

 terminal margin the veins are slenderly but conspicuously yellow. 

 Hind wing : base and a broad posterior area down to the disc 

 irrorated with black scales, with a sparse clothing at the base of 

 long yellow hairs; an orange-yellow discocellular spot, sometimes 

 wanting ; terminal margin towards the apex with broad blac-k 

 border and superposed yellow spots, somewhat as in the fore wing 

 but not at all clearly defined ; both the black border and the 

 superposed yellow spots on it fade out posteriorly and are merged 

 in the ground-colour, which extends to the tornal angle and to the 

 margin above it. Underside : ground-colour similar but somewhat 

 paler. Fore and hind wings shaded with green as follows : Fore 

 wing on the costa, the apex and more or less along the terminal 

 margin ; hind wing over the whole surface, but most densely 

 over the basal four-fifths. On both fore and hind wings the
