slender shining leaden-grey semicircular line bulging outwards from 

 the costal and recurved to the dorsal margin about the anal angle ; 

 at the apex is a conspicuous black spot, from which a curved black 

 line runs through the cilia towards the anal angle, but is ended 

 abruptly before reaching it ; between this and the semicircular 

 shining line already mentioned is an oblique straight black line 

 following the margin of the wing at the base of the ciUa and reach- 

 ing upwards nearly to the costo-apical spot ; cilia tipped with 

 black at the extreme apex, those on the hind margin pale reddish 

 grey. Underside brownish fuscous. 



Hind wings grey ; cilia pale reddish grey. 



Abdomen reddish grey. 



Legs : hind tibiae fringed above with separate pale yellowish 

 hairs, giving a pectinate appearance ; a black spot lies at the base of 

 the spurs and three black bands on the tarsal joints, which are 

 otherwise white.

This species is closely allied to Oracilaria leuconota, Z., from 

 Ubaque, which also probably belongs to this genus ; the species now 

 described differs chiefly in the larger dark apical spot, which is 

 placed nearer to the costal margin, and in the presence of the oblique 

 black streak below it. I am justified in separating it from the genus 

 Gracilaria on account of its much longer antennae and its slender 

 long recurved palpi ; the maxillary palpi, although undoubtedly 

 present in the typical Zarathra, are not quite so strongly developed 

 as in this species, but the shape of the wings is the same, and, so far 

 as I can judge without denuding the specimen, the general pattern 

 of neuration is similar. This genus is not confined to South America, 

 but extends also to Africa and the Indian region.

 Gracilaria, Hw. 



Gracilaria iENEOCAPixELLA, sp. n. 



Antennae greyish, faintly spotted with paler colour. 



Palpi whitish, outer half of second joint fuscous, except at the 

 extreme apex. 



Head shining iridescent bronze ; face shining metallic whitish. 



Thorax shining bronzy. 



Fore wings tawny purplish, mixed with pale lemon-yellow beyond 

 the basal fourth ; a conspicuous broad pale lemon-yellow band 

 extends from the basal third along the costal portion of the wing to 

 the apex, its margin not clearly defined, the tawny purple blending 

 into it from below ; this band is widest and most conspicuous about 

 its commencement, where it contains one or two minute fuscous 

 costal dots ; a series of dark purple strise is also visible along the 

 dorsal margin, and some small groups of fuscous scales are on the 

 apical portion of the wing, reaching to the extreme apex ; cilia at
