 brown atoms ; inner line faint, double, brown, powdery ; median shade 

 powdery, angled on the median vein ; outer line distinct, purplish,

 white, basal spots and narrow subbasal line shown, claviform obliquely 

 elliptical, cut by the submedian fold ; orbicular small, rounded, cut by a

Type, No. 11414, U. S. National ^Museum. 



The specimen bears Mr. Schaus's label, '•' Hydroicia piirpurifascia, 

 G. and R.," but it differs from that species in its lighter appearance, 

 caused by the reduction of the terminal shading and the total absence of 

 the white spots, it may be considered as a Western representative of 

 pui'purifascia^ specifically distinct, I have no doubt. 



Gortyna triorthia, n. sp. — Fore wing light yellow, heavily shaded 

 with brown in the middle, leaving the costal and inner edges and the 

 space between median and outer lines clear yellow ; inner line faint, 

 double, brown, forming an outcurve below vein i ; median line shaded 

 distinct, bent where it touches the reniform below ; outer line very 

 straight, purple, followed by a purple shade, which is dentate on the veins 

 without ; subterminal line indicated by a narrow, clear yellow space ; 

 red powderings terminally ; claviform and orbicular in a rigid, oblique 

 line, white, full, nearly fused, the claviform dumb-bell-shaped, the 

 orbicular elliptical ; reniform a yellow arc, surrounded by spots, a narrow 

 white one at the upper and lower corners within, four without, of which 

 the second from the top is rather strongly shaded with yellow. Hind 

 wing testaceous, faintly shaded with brown subterminally. Expanse, 

 36 mm.
