saturatiore pone medium, et post earn plaga magna caeruleo- 

 nigra, fascia teniii recta alba ante punctum apicali nigrum. 

 Exp. al. 5| lin. 



Head greyish-oclireous, with a faint olive tinge. Face pale 

 greyish-ocbreous. Maxillary palpi white, spotted with dark 

 fuscous. Labial palpi white, with the base of the 2nd joint and 

 two spots on the terminal joint dark fuscous. Antennae pale 

 fuscous, with darker annulations; the 2nd joint elongate, pale 

 oclireous-grey in fiont, dark fuscous behind. 



Anterior wings greyish-ochreous with a faint olive tinge, with 

 an oblique, darker fascia beyond the midille, followed by a large, 

 irregularly-shaped blue-black blotch; before the apical black 

 spot is a slender whitish fascia, perpendicularly placed. The 

 basal portion of the wing is rather irregularly marbled on a 

 paler ground-colour, the first defined marking being the oblique 

 fascia, which is anteriorly edged with blackish, and broadest on 

 the inner margin ; the blotch beyond this begins on the disc, 

 sharply edged with black ; it then extends to the costa, along 

 which it attains' a considerable breadth, enclosing (on one wing) 

 a small costal spot of the pale ground-colour; it slopes gradually 

 towards the inner margin, which it reaches just at the anal angle; 

 its outer edge is pretty well defined by black scales, and it is 

 followed immediately by a slightly oblique fascia of the pale 

 ground-colour towards the costa, but much suffused towards the 

 inner margin. Then follows a fuscous patch nearly of the colour 

 of the central fascia ; it is intersected by an oblique black streak, 

 beyond which . is the slender, dark-margined, perpendicularly- 

 placed, white fascia ; at the apex is a minute black spot. Cilia 

 olive-brown, paler towards the tips, intersected by two blackish 

 lines ; cilia of the inner margin dark grey. 



Posterior wings dark grey, with grey cilia. 



Thorax greyish-ochreous, with a faint olive tinge. 



Anterior legs : femora and tibiae dark brown ; tarsi white, 

 spotted with dark brown. Middle legs: femora whitish-grey; 

 tibiae dark brown ; tarsi white, spotted with dark b^own. Pos- 

 terior legs: femora and tibiae whitish- grey ; tarsi whitish, spotted 

 with dark fuscous. 



A true Gracilaria, reminding one slightly of G. Syringella. 



I have only seen a single specimen (of which the abdomen is 

 wanting); it was captured by Mr. Sylvester Diggles, at Moreton 

 Bay, North Australia.
