The species according to Hampson's key would fall into the above 

 genus, although totally dissimilar to the other species placed here. 

 Superficially it bears considerable similarity to our Leucocnemis vari- 

 abilis but is darker and heavier marked. Possibly its nearest ally is 

 Paracretonia aleptivoides B. & McD. a desert species from the same 

 general region. 



Tarache CORA sp. nov. (PI. XVII, Figs. 19, 20). 



$ . Front and collar white ; thorax largely purple-brown, the patagia 

 shaded with white ; abdomen dull ochreous ; primaries with hyaline fovea at 

 base ; costal edge to near apex broadly white, narrowing beyond cell ; remainder 

 of wing purple-brown, shaded with olivaceous just below the white area which 

 is crossed by two yellow outwardly oblique bands, dividing the wing into three 

 equal parts, the border line between the light and dark areas of wing forming 

 a slight angle where the inner yellow band touches it ; above inner margin 

 beyond fovea some slight pale marks indicate the t. a. line ; reniform round, 

 partially projecting into white costal area and outlined in blackish; t. p. line 

 only distinct above inner margin as a waved white line margined inwardly 

 by olivaceous which is preceded by some bluish-white scaling; subterminal 

 area shaded with bluish-white; terminal area white, broadest above anal angle, 

 narrowed to a point some distance below apex, bisected by a pale yellow shade ; 

 terminal dark dots on apical portion of outer margin ; fringes white with a 

 slight apical dark shade and a larger one opposite cell ; secondaries hyaline 

 whitish, shaded along outer margin with brownish ; fringes with basal half 

 pale brownish, outer portion white. Beneath primaries smoky brown with cell 

 ochreous; secondaries paler than above with faint dark discal dash. Expanse 

 25 mm. 



$ . Larger than S with basal half of primaries white, crossed by a 

 broad sinuate yellow band originating in a purple-brown costal blotch and 

 preceded by a bluish-gray costo-basal round spot and similar shading along 

 inner margin ; orbicular a small round blue-gray spot ; reniform a similar 

 larger spot partially encircled with white; a faint gray shade between spots; 

 outer area of wing purple-brown shaded with olivaceous and blue gray with 

 large triangular white costo-apical spot ; a strongly sinuate t. p. band bends 

 around reniform, largely olivaceous, bordered outwardly with blackish and 

 arising from a blackish blotch on costa; irregular bluish-white shading sub- 

 terminally; terminal area and fringes as in S except latter have slight dark 

 shade above anal angle. Secondaries pale smoky, darker outwardly. Beneath 

 primaries smoky with palish costo-apical patch ; secondaries creamy with small 

 discal dash. Expanse 28 mm.
