THE CANADIAN ENTOMOLOGIST. 79 



Abdomen nearly black above, with four lemon-yellow dots on the lower 



segments ; beneath lemon-yellow. Legs black above, white beneath. 



U[)per side of fore wing trans{)arent, with tawny, black and yellow 



markings. Costa black. Discoidal space transparent, with dusting of 



tawny scales towards the base, and a suggestion of a black spot near the 



centre. A heavy dusting of bl.ick scales extends from the costa downwards 



across the end of the discoidal space, suffusing to hind margin along the 



median nervure, and also along the first submedian nervule, somewhat 



tawny near the margin. Apical area black. Between the apical area 



and the band or dusting of black scales above noted, the space is trans- 

 parent, heavily dusted with brown scales near the costa. The space below 

 median nervure to the hind margin is black, with tawny scales along the 

 nervure. 



The upj)er side of hind wing has the same ground colouring. The 

 upper half of the wing, including the discoidal space and its immediate 

 surroundings, is transparent, the nervures and nervules being heavily 

 dusted with lemon-yellow. The edges of this transparent area are black, 

 the lower portion forming a band across the wing from the centre of inner 

 margin nearly to the upper angle. This transparent area shows a tendency 

 to extend downwards to hind margin in the first submedian interspace. 

 Below this the area to hind margin is tawny. The hind margin has a 

 generous black border, wavy on its basal edge. 



The under side of both wings is the same as upper surfaces, the 

 dusting of lemon-yellow scales being more marked. At the apex of the 

 fore wing are four interspacial white spots, and in the black border of the 

 hind margin of the lower wing is a series of prominent interspacial white 

 spots. 



Variations. — This species varies greatly in the density and suffusions 

 of its markings. The transparent area of the lower wing in some speci- 

 mens extends downwards to hind margin, cutting off the black band and 

 the tawny area at the first submedian nervule. The white spots at apex 

 of the under side of fore wing are at limes entirely wanting.
