tilled by parallel rippled grey stripes, the first of which is ac- 

 centuated and pointed on each nervnre : all the lines empha- 

 sised on the costa ; extreme hin<l mariiin irregularly edged 

 by bhuk streaks and dots ; cilia grey or grey-brown. Hind 

 wings elongated and ample, rounded behind, but the dorsal 

 margin long and straight ; shining silky white, tinged with 

 grey : nervures faintly brown ; costal margin clouded with 

 grey-brown shades; and sometimes two similar ti-ansverse lines 

 lie near the hind luargin, which is dotted with brown; cilia 

 brcjwnish-white. Female stouter in the thorax, and in the 

 abilomen still mure so ; fore wings shorter and bi'oader, with 

 the costa more arched, and the markings more definite, re-

 tinct grey transverse strijies, and on the hind wings into a 

 hind-marginal stripe.

 costal i-egion yellowish-white, twice barred with smoky-

 Occasional specimens of pale ground colour have all the dark 

 markings collected into a single broad dark central band ;

 hind margin. In the collection of the late Mr. F. Bond is a 

 male of uniform ochreous-white colour : another very dark
