Tlie aberration plumbea is analogous to the aberration fasciata of clathrata, 

 the inner and outer lines being swollen into dull leaden-grey bands only about 

 half as wide as those in fasciata, the outer band edged inwardly with blackish, 

 a streak of the same grey filling up the interval between veins 3 and 4 to the 

 margin, and another streak, bnt much narrower, running along vein ; the space 

 between this band and submarginal line being filled in with deep red-brown ; 

 the costa is of the same tinge as the bands. 



Head, thorax, and abdomen as in the type form.

While the type form and its aberration plnnihca are represented only by ? ? , 

 the aberration atriplena is a c? only. 



Forcwing : yellow, dotted witji orange, and with the veins orange ; costal 

 area brownish grey with dark speckling ; the lines swollen into bands, as in the 

 ab. jilnmbca, but the outer one twice as broad, and both suffused with black, which 

 to a great extent obliterates the leaden-grey tints ; the bands as well as their 

 extensions to the hiudmargin are more conspicuous owing to the paler ground- 

 colour. 



Uindwiiuj : the same. 



Underside pale ochreons, witli the black liaiids both shown. 



Abdomen orange-red with black bars at the hinder edge of each segment. 



Expanse of wings : 3s mm.

1 have no doubt that the ground coloration of this c? is the normal ground- 

 colour of the cj in all its forms ; and it is possible that the aberration afri/j/cna 

 may be the corresponding c? form to the ? aberration pliunbea ; though in that 

 case the difference in the coloration of the sexes is much greater than in the 

 corresponding aberration of clathrata and its type form. 



The antennae of the S of both alhihasis and clathrata differ from true Si/iit.aracta 

 in being serrate, with short I'ascicles of cilia, these being much shorter in albibasis 

 than in clathrata,.

(S. Forcwing : jiale ochreo\is, speckled with rusty-edged brown granules ; the 

 veins and lines brown ; costal area above subcostal vein dull grey-brown, the costal 

 edge dotted with ochreons and brown ; first line thick, curved, at one-third, luiinlate- 

 dentate, toothed inwardly on the veins and outwardly between them, jirecedcd 

 by a i)ale ochreons space ; outer line at two-thirds, parallel to hiudmargin, also 

 double and lunulate-dentate, followed by a line of unspeckled ochreons ; submarginal 

 line single, indented on submedian fold, followed by a [lale space ; all three lines 

 start from the subcostal vein ; veins 3, 4, and I) thickened to hiudmargin ; a dark 

 fine marginal line ; cell-si)ot black ; fringe ochreous, chequered with brown beyond 

 veins. 



Jlii/diciiig : without basal line. 



Underside (piite pale ochreous, with all the markings dull grey. 



? suffused with grey-brown, the lines and veins grey-brown; only the (hrec 

 pale edges of the lines remaining clear ochreous, the rusty speckling being much 

 thicker ; costa ochreous grey, dusted with black. 



Face, vertex, and paljii yellow and fulvous ; shoulders concolorous with costa ; 

 patagia fulvous ; dorsum marked with brown saddle-shaped marks with pale
