Argyronympha ugiensis, n. sp. (Plate XXXIV. fig. 3.) 



Mnle and female. — Upperside orange-red : primaries with a black 

 marginal border extending on costa from end of cell to rather beyond 

 middle of inner margin ; border very broad at apex, constricted and 

 narrowest at second median nervule, widening out again at first 

 median nervule : secondaries, costa blackish brown, ba^e and margins 

 broadly clouded with dusky, and with some indistinct dusky markings 

 across disk ; a black and rather indistinct submarginal line widening 

 out between subcostal nervules into a linear-shaped blotch ; all the 

 nervures dusky. Underside : primaries orange-red, not quite so 

 bright as upperside ; a submarginal silvery stripe bordered outwardly 

 by a narrow very dark fuscous line ; a short oblique silver stripe 

 extends from inner margin near hinder angle to halfway between 

 first and second median nervules, and with its apex almost touching 

 the submarginal stripe : secondaries, basal half greyish ochreous, 

 thickly irrorated with minute black dots ; an oblique reddish-brown 

 stripe from near costa crosses the wing, and encloses upper part of 

 cell and terminates near anal angle ; this is bordered outwardly by a 

 curved or double crescent-shaped silvery band, which is again 

 bordered by a pale ochreous-yellow band ; a narrow submarginal line 

 of silver bordered outwardly by reddish ochreous, and inwardly, from 

 submedian nervure to discoidal nervule, by reddish brown ; between 

 the discoidal nervule and first subcostal nervule there are four jet- 

 black and somewhat square-shaped spots, with their bases resting on 

 the submarginal line ; between first and second subcostal nervules 

 are two additional black spots, above the others, the space between 

 them, which is ochreous, forming a complete St. George's Cross, and 

 the whole inwardly bordered by a silvery band ; between submedian 

 nervure and two median nervules a silvery horseslioe-mark bordered 

 outwardly and inwardly by reddish brown ; all the wings margined 

 by a line of dark reddish brown. The silvery markings have 

 opalescent tints in various lights.

 and turns back and runs parallel to itself as far as third median 

 nervule, this is bordered inwardly by dark chestnut ; a pale yellowish 

 stripe from near apex to first median nervule, its lower half between 

 the silver bands ; beyond this to grey part of wing a broad band of 

 chestnut : secondaries, basnl |)art, including half of cell to near anal
