The name tiiaiisitcta being already employed in the genus for a form 

 of cornea H. S. we would propose the above name for this species, 

 and append following description : 



Palpi dark gray beneath, black above ; third joint almost entirely black, 

 black lateral dot at base of second joint with a slight reddish shading, antennje 

 bipectinate in both sexes, brown ; head and thorax dark gray, especially notice- 

 able in female ; patagia with black dot and central stripe, bordered inwardly 

 with white ; abdomen pink, last segment sometimes with black patch, beneath 

 gray, with a double lateral black stripe : tibiae and tarsi gray ringed with black ; 

 anterior femur more or less pinkish. Primaries hyaline, more or less sprinkled 

 with black and various shades of gray ; five black patches on costa with gray 

 interspaces indicate the usual bands, of which the subbasal one alone is con- 

 tinued nearly across wing ; basal portion of inner margin gray, followed by 

 two black patches separated by gray, in female more or less confluent ; disco- 

 cellulars and basal portion of vein Mo, as well as cubitus at origin of Cu,, 

 black ; veins in subterminal area tinged with black ; outer margin dark brown, 

 shaded inwardly with light gray and containing some diffuse black marks ; 

 fringes smoky, checkered with gray at extremities of veins, most prominently 

 at anal angle. Secondaries hyaline, smoky gray, with slight discal dot and 

 dark outer margin towards apex. Beneath as above, more hyaline, markings 

 less distinct ; costal border of secondaries gray, terminated by black.

 tially defined by black, reniform indistinct, with black margin on basal side, 

 both spots concolorous with wing, claviform absent, t.p. line geminate, dentate, 

 from a point on costa above reniform strongly outcurved to well beyond same,
