150 MR. G-. T. BETHUNE-BAKER : A REVISION OF THE 



secondaries the costa is broad. Underside : both wings brownish grey. Primaries with 

 a narrow, even, obscure, transverse band to the lower median nervule ; submarginalband 

 darker and broadish at the anal angle, tapering away below the apex. Secondaries with 

 an obscure narrow spot closing the cell and another obscure one below the cell; 

 transverse band distinct, moderately even, lightly edged interiorly, but the outer paler 

 edging diffused ; submarginal row obscure, palely edged in the anal area ; a small 

 black spot at the anal angle, a larger one between the second and lower median nervule, 

 the space between and over which is very pale bluish white. 



2 . Upperside : primaries blackish, with a paler and less purple-blue patch from the 

 discoidal to the submedian nervule aud about a third over the median area. The 

 secondaries are bluish from the upper discoidal to the submedian nervure with a broad 

 dark margin, all the nervures showing broadly black. Underside as in the male, but 

 with all the markings very much obscured. 



This is a very distinct species and is recognisable at a glance ; it is very near fulla 

 Hewitson, the distinctions being recorded under that insect.

6 ■ Upperside : both wings brilliant shining violet-blue ; the primaries with an 

 exceedingly narrow black costa and narrow black posterior margin ; secondaries with the 

 costa broadly and the posterior margin narrowly black, abdominal fold greyish, a 

 slight tooth-like projection at the end of the lower median nervule. Underside : both 

 wings pale, slightly rufous brown. Primaries paler in the submedian area, spotless, with 

 a narrow transverse band to the lower median nervule somewhat obscure ; submarginal 

 and marginal areas rather darker. Secondaries with an exceedingly obscure spot in the 

 cell and a very narrow dash closing it; beyond this a broadish band of darker shading 

 edged indefinitely rather palely, the exterior edging broadly pale ;-> marginal and 

 submarginal areas darker, divided at the anal angle by a pale curved line ; a very small 

 black dot at the extreme anal angle. 



2 . Upperside: both wings paler and less violet than in the male; primaries with 

 costa and posterior margin broadly and apex very broadly blackish ; secondaries with 

 costa very broadly and posterior margin narrowly black. Underside as in the male. 



This species may be known from canulia Hewitson by the bluer and brighter 

 colour of the upper surface and by the darker, redder, and warmer tone of the under 

 surface. Canulia has a very cold greyish under surface and has also distinct black anal 

 spots with metallic scaling, which are absent in this species.
