Macaria fieldi, n. sp. 



Ma/e— Expanse 20-23 mm. Head, antennae and legs light ashen 

 gra\'. Thorax and abdomen light ashen gray, with a slight pinkish 

 cast. Fore wings light ashen gray intradiscally, becoming fuscous 

 beyond. They are clear ashen gray to the basal line, which is 

 broad and strongly black at the inner margin, running at a slight 

 angle to the median vein, where it seems to fade out, and there is 

 just a trace of an orange line tt) tlie costa. The mesial space is 

 also clear ashen gray, sometimes with a pinkish ca^ in fresh 

 specimens. Discal spot black, with a paler centre, forming a ringlet 

 of considerable size. The extradiscal line appears as a spot on 

 the costa, just below which it is apparently broken off, running 

 out sharply at a right angle, then connecting with a heavy black 

 line, which runs almost straight to the inner margin, curving in 

 slightly from Ms to the margin. The bhick extradiscal line has 

 a faint orange line bordering it inwardly, appearing stronger when 

 the black is faded out. Be\ond the extradiscal line there is an 

 irregular blackish or fuscous clouding, apparently bordered by an 

 irregular whitish line. Beyond this clouding the margin of the 

 wing is slightly paler, and there appears to be a minute black 

 dot at the base of the fringe on each vein. Fringe on all the wings 

 fuscous. Hind wings basally light ashen, darker at outer border, 

 more or less strigated. There is a prominent black discal spot; 

 beyond this an extradiscal line, which runs straight across the 

 wing, sometimes fading out before reaching the outer margin. 

 Beyond this is a faint whitish line, appearing like a continuation 

 of that of the fore wing, though not apparent in all specimens. 

 Beneath, very pale ashen, the lines above showing through. The 

 fuscous clouding appears on both fore and hind wings, not cjuite 

 reaching the outer margins. The discal spots are prominent and 

 black on all the wings. 



Female paler than the male, the black extra- and intradiscal 

 lines very faint, with an orange shading, sometimes appearing as 

 pale orange-coloured lines. Fuscous clouding less heavy. Beneath,
