 Reniform distinct, round, white centered; outer dark margin broad; base 



white or creamy only to the t. a. line or a little beyond. ..teiiuicola. 

 Reniform as before, dark shade forming only a large quadrate patch on the 



inner margin, else luteous or olivaceous, except at base libedis. 



24. The dusky shade is smooth, glossy and extends to the apex 25. 



25. Secondaries white or nearly so; outer dusky baud of primaries narrow and 



broken iieomexiciiiiia. 



Secondaries more or less smoky, with white fringes; altogether darker; outer

Head, thorax and abdomen white, with a faint yellowish tinge, which is best 

 marked on the abdomen. Palpi short and weak, hardly exceeding the front of 

 the head. Primaries creamy white at base: below median vein this is bounded 

 by a broad black median shade, which is upright and conspicuous from median 

 vein to inne rmargin : above this the creamy shade extends into the s. t. space, 

 though irregularly and not definitely bounded anywhere. T. p. line fragmen- 

 tary, deeply sinuate, mostly olivaceous, partly black marked. S. t. line white, 

 broad, very irregular, sending a long spur into the submedian interspace. This 

 line is partly preceded by luteous brown, and in the lower half of wing by irregu- 

 lar bluish and gray mottlings. Terminal space mottled with leaden gray, or 

 ochreous and white, the apex always dark. A broken black terminal line. 

 Fringes mostly dark, with a prominent white patch below the middle. Orbicular 

 black, punctiform, always present. Reniform upright, oval, incompletely out- 

 lined in black, followed by a rather prominent black spot which rests ou the t. 

 p. line. Secondaries smoky or paler, glistening; fringes white. Beneath, pri- 

 maries smoky to blackish, irregularly paler along the outer and costal margins. 

 Secondaries white or faintly yellowish, the outer margin dusky, a dusky half 

 band from costa, and a small discal lunule.

Twenty two example.s are before me, and no two are alike. The 

 tendency is, primarily, to soft, silver gray shadings in the pale basal 

 space, which may become so complete that only a pale t. a. line is
