straight, rather oblique ; fuscous-grey or dark grey, densely irrorated with 

 white, especially in disc ; a very small dark fuscous triangular spot at base 

 of costa; first line whitish, distinct, posteriorly suffusedly margined with 

 dark fuscous, rather strongly oblique, slightly curved, somewhat indented; 

 orbicular small, oval, whitish, dark-margined, detached; claviform repre- 

 sented only by a small dark spot very obliquely beyond orbicular ; reniform 

 large, irregularly 8-shaped, grey, margined first with whitish and then 

 incompletely with dark fuscous, dark margin strongest on anterior inden- 

 tation ; second line whitish, distinct, anteriorly dark-margined and with 

 blackish dots on veins : terminal space hardly irrorated with white, except 

 broad suffused subterminal line, not interrupted ; veins posteriorly obscurely 

 blackish : cilia white, basal third barred with grey, and with a grey 

 posterior line. Hindwings If, very pale whitish-ochreous ; apex in female 

 greyish ; cilia ochreous-white. 



Characterized by the absence of black markings. 



Bealey Eiver (2,100 feet), Castle Hill (2,400 feet), Lake Guyon, and

 64. Xer. cy amenta, n. sp. " 



Male, female. — 25-28 mm. Head and thorax grey, irrorated with white, 

 with a short blackish or dark fuscous lateral stripe from eye, not reaching

 Antennas grey ; ciliations \. Abdomen whitish-ochreous. Legs white,

 wings very elongate, triangular, costa slightly arched, apex obtuse, hind- 

 margin straight, somewhat oblique ; fuscous, densely irrorated with white, 

 especially in disc ; a black median streak from base of costa to first line ; 

 first line white, tolerably distinct, moderately oblique, somewhat curved, 

 rather indented, posteriorly strongly black-margined on upper half ; orbicular 

 oval, whitish, outlined with fuscous above and black beneath, touching first 

 line ; claviform similar, margined with two or three blackish spots ; reniform 

 8-shaped, obscure, fuscous, partially dark-margined, cut by a strong black 

 longitudinal streak from near orbicular ; second line white, distinct, 

 anteriorly dark-margined; terminal space hardly irrorated with white, 

 except suffused broad subterminal line, interrupted above middle ; veins 

 posteriorly obscurely blackish : cilia white, basal third barred with dark 

 fuscous, with a fuscous posterior line. Hindwings If, pale whitish- 

 ochreous ; postmedian line obscurely indicated ; apex and upper part of 

 hindmargin very narrowly grey ; cilia ochreous-white. 



Very closely allied to X. petrina, but distinguished readily by the various 

 sharply defined black markings.
