Secondaries with a narrow terminal line, edged interiorly, at the anal angle, 

 with a short white line ; two tails, the outer short, and tipped with white, the 

 inner one three times the length of the outer, and fringed exteriorly with 

 white. Fringe brown. 



Under side reddish brown, suffused with greenish and olivaceous, espe- 

 cially on the apical area of the fore wings and over the whole hind wings. A 

 transverse white line, bordered interiorly by a ferruginous streak, runs from 

 the outer third of the primaries' costa, nearly parallel with the outer edge, to 

 the abdominal margin. Secondaries with a terminal white line, and a small 

 black anal patch ; the lower part of the area enclosed between those two white 

 lines is strewn with violaceous ash-white atoms, and there are two prolonga- 

 tions of the inner white line, respectively down the first and second median 

 veinlets, usually uniting with the ashy space below. Posterior to this line 

 there are three oblong black spots encircled with white, and following the cen- 

 tral of these a larger violaceous brown patch. Expanse 1*12 inches. An- 

 tenna? black, annulated with white, club ferruginous. 



Female. Upper surface reddish ochreous ; the black margins are much 

 broader than in the male. Underneath the surface is more greenish ; expanse 

 1-25 inches.

Male. Upper side brilliant, shining blue, a black border of moderate width 

 on the primaries, broadest at the apex ; narrower upon the secondaries, which 

 have two tails, the inner being the longest and tipped with white ; there is 

 the usual smooth sexual spot at the end of the fore-wings' cell, and obliquely 

 below, and connected with it a large black patch. 



Underneath brown tinged with purplish ; on the primaries a submarginal 

 band of obsolete dashes and a sinuated median row of six black spots extend- 

 ing from the costa to the first median veinlet. 



Secondaries with three transverse bands and lines ; the first is composed of 

 interrupted black spots and dashes, bordered posteriorly with pale silvery- 

 blue ; the second is a waved black line, above which is super-imposed a broad 

 stripe of silvery-blue atoms, and the third is marginal and silvery blue ; 

 there is besides a large black anal patch, and a small black spot above and 

 midway between the two tails, surmounted by a reddish crescent ; also a large 

 rounded black dot above the cell. Fringe brown ; expanse 1*4 inches. 



Body above glossed with lustrous blue ; underneath brown, abdomen yel- 

 lowish.

Female. Upper side shining greenish blue ; costa of primaries, and a very 

 broad outer belt, black ; secondaries with a broad brownish-black outer mar- 

 gin, cut by a narrow, submarginal, white line ; two tails, the fringe from the 

 apex of the primaries to the lower of these, white ; this has the anterior side 

 fringed with black, and the posterior with white ; hence to the anal angle the 

 fringe is black. 



Underneath light brown ; the fore wings crossed between the middle and 

 apex by four transverse white stripes, of which the first runs parallel with 

 and close to the outer margin ; the second starts near the apex, and in com- 

 mon with the other two, rising respectively at three-fourtlis and one-half the 

 length of the costa, converges towards the inner angle ; a short line running 

 above the submedian vein unites the three ; the third is bent very abruptly 

 immediately before this junction. 



Secondaries have two submarginal white lines, united at the outer angle 

 and on the second and first median nervules ; the upper one, in the space 

 included between these two veinlets, is replaced by a black line surmounted
