on the upper edge and ends on the median nervure. The secon- 

 daries have beyond the middle a whitish line, straight in its first 

 half, angular towards the anal angle, where it describes a kind of 

 M, and then continuing to the side. Between this line and the 

 outer edge there is another line, less distinct, shaded outwardly 

 with blackish, interrupted by a red spot, situated in the space 

 between the two tails. The anal angle has a black spatule, sepa- 

 rated from the internal tail by a square pale blue spot. At the 

 base of the tails there is a small white or grayish line which sepa- 

 rates the fringe, which is also white in this part of the wings. 

 The base of the upper edge of the primaries is reddish, and the 

 middle of the secondaries, near the upper edge, is marked with a 

 whitish point. 



Body, bluish above ; ashy gray below. 



Antennae blackish, annulate with white ; club blackish, tipped 

 with fulvous. 



In some specimens there is a small red spot on the spatule of 

 the anal angle. 



Larva slightly pubescent, pale green, a little yellowish, with a 

 dorsal ray and seven oblique streaks, green. 



Head black ; marginal ray yellow, slightly shaded with obscure 

 green on its upper side. Feeds on Quercus.

Same size as T. M-album, and most probably a mere variety. 

 The four wings glossy blue, a little violet, with a wide black border 

 as in T. M-album. The primaries sometimes have the costal margin 

 a little reddish at the origin. 



Secondaries with two tails; generally a small red spot at the 

 anal angle ; sometimes a small white spot on the disk of the pri- 

 maries, in the male. 



Under side dark, cinereous. Primaries traversed in the upper 

 half by two whitish rays, meeting at their lower extremity. Secon- 

 daries traversed to the middle by a white ray describing a sort of 

 M. Between this ray and the external edge there is another, 

 which is interrupted between the two tails by a red spot. Near
