 Alls supra omnibus fumosis, argenteo-splendentibus ; subtus, anticis 

 fuscis, Uneaque apicali lactea ; posticis fuscis, lineaque in similitudinem 

 irianguli albida lactea. Exp. alar., 39 mm. 



Hah. : Punta Arenas, in Preto Magellanico ; mensis Junius. 

 Wings on the upper-side of a shining smoky-silvery hue, with the markings of 

 under-side showing through ; under-side, fore-wings of a darker colour than above ; 

 costal border and apex ferruginous, with a short milky-white dash at apex ; hind- 

 wings of a beautiful chocolate-colour, crossed by two diverging milky-white stripes, 

 running from the base of wing to outer border, the one running parallel to the 

 abdominal border, the other (which is slightly arched) on the upper third of wing ; 

 from the abdominal border just above the inner angle of wing another stripe runs 

 towards the outer angle of wing, crossing the abdominal stripe, and on reaching the 

 upper curved one, turns off abruptly at an obtuse angle and terminates at the outer 

 third on the upper border of the wing, so that these stripes form a large triangle 

 with prolonged sides ; on the outer border of the wing and midway between these 

 prolongations is a white dash, this dash and the upper edge of curved stripe are 

 black bordered ; on either side of curved stripe above the cell are two little dashes ; 

 thorax colour of upper-side ; abdomen smoky-bi'own. 



This species is easy of recognition ; a large milky-white triangle 

 on a chocolate-coloured ground. 



This species differs from Butler's S. columla, Trans. Ent. Soc , 

 page 422, 1882, in its having the abdominal stripe from base to mar- 

 gin in lieu of the two oblique dashes, and the marginal line instead 

 of the spot on the second median interspace, as also in its larger size.
