 of costal area dusted with blackish. Apical area bordered inside with blackish ; 

 the rest of the wing pearly bluish-grey, with a large whitisli spot on the 

 inner margin, and the two innermost yellow spots of the upper side faintly 

 visible. Posterior wings yellow, mottled with ])rown, especially about and 

 above the end of the cell ; a row of pearly white spots curves from below 

 the costal nervm'e, to the middle of the inner margin, in addition to which

" Nearly allied to L. Medora (Doul)leday), fr(_>m which it differs on the upperside by having 

 the central l>anj of the anterior wings broken, and on the underside by the white spots of the 

 posterior wing" (Hewitson). The male of D. Medoriua also slightly resetuljles D. Idonia 

 (Hewitson), but in the latter speciL's the lower spot of the inner row ou the anterior wings is 

 Ycry large, and the posterior wings are destitute of any orange markings, being only marked with 

 a rather na,rr(.iw yelh^w band.
