266 THE CANADIAN ENTOMOLOGIST. 



Under side of hind wings is entirely of bronze colour, somewhat 

 lustrous, excepting at the top portion of each interspace, where there is a 

 whitish spot, and inside of that, one-sixteenth inch from margin, a 

 semicircle of brick colour, very prominent. The dentations of the wing 

 bear the white linear border appearing on upper side. 



The specimens in my possession were taken some two hundred miles 

 north from Cochabamba. In general appearance, it resembles closely 

 Papilio Numitor, Cram., and that group, and may be a climatic variation 

 of it, but in Numitor the greenish-white dashes on hind wing follow more 

 closely the contour of the hind margin, while in this these dashes are 

 more in line with a line drawn from apex to anal angle. My specimens 

 are invariable, showing no difference in the suffusion or size of dashes. 



Dynamine albi'dula, sp. nov. 



Habitat: Bolivia, near Sicasica. Expanse, 1.25 inches. 



Head, palpi, thorax and abdomen above, blackish with gray hairs ; 

 beneath, nearly white. Antennae, black with white annulations at the 

 base of each joint. Club, tipped with tawny. Legs, white. 



The lower portion of the fore wing is white, from a line drawn from a 

 point close to the base on inner margin, and extending upwards to and 

 along the median nervure to end of discoidal space, then curving down- 

 wards to lower angle, meeting inner margin one-sixteenth* inch from 

 angle. The rest of the wing is black with white spots. The discoidal 

 space is heavily dusted with lustrous greenish-blue scales. In the centre 

 of the space is a small white spot. Midway between apex and base is a 

 large white spot, extending from costa towards hind margin, and directly 

 over the summit of the lower white area. Just within hind margin, one- 

 third distance from apex to lower angle, is a smaller white spot, and 

 there is another below it, one-third distance from lower angle to apex. 

 The latter of these merges into the white area of the lower portion of the 



wing. 



Upper side of lower wing is entirely white, excepting a small area 

 of black at the very base, and a narrow border of black along hind 

 margin. This border is black at the upper angle, and turns to grayish at 

 the lower half, disappearing entirely just before it reaches anal angle. 

 Outside of this, on the edge of the margin, is a white thread. 



The white area of upper side of fore wing is duplicated on underside. 

 The black of the upper side gives way to a great extent to tawny. The 

 discoidal space is jet black at its upper portion, tawny at basal portion,
