Chiomhas Ivallda, Mead, Cau. Ent., X., p. 196, 1878. 



Male. — Expands from 1.8 to 2.-3 inches. 



Ujiper side of primaries blackisli-brown, varying in individuals from dark to 

 pale ; the costal margins finely and transversely streaked gray and brown ; the 

 hind margins narrowly edged with brown ; on the lower side of cell and partly 

 within it a black sexual band, sometimes obsolescent; between the nervules a 

 series of elongated gray-ochraceous spots, nearly or quite filling the inter- 

 spaces, usually six in number ; but sometimes the uppermost one is wanting ; 

 in one example examined there is no trace of these spots (Fig. 5) ; on the second 

 spot from costa is a black ocellus, always small, sometimes minute, with white 

 pupil ; and in about one fourth the examples there is a minute spot on the 

 lower median interspace, rai-ely large enough to admit a pupil. 



Secondaries gray-ochraceous, edged with brown; in submedian interspace is 

 usually a small pupilled ocellus ; fringes bi'own at the ends of the nervules, white 

 in the interspaces. 



Under side of primaries gray-ochraceous, the costa black and white ; the upper 

 part of cell streaked transversely with brown, — sometimes the entire cell ; about 

 three fifths the distance from base to arc some of these streaks become confluent 

 and form a sinuous bar ; the disk is crossed by a brown stripe, which projects^ a 

 long tooth upon upper branch of median ; below this the stripe is twice roundly 

 incised, and sometimes projects a spur along the sub-median interspace nearly or 

 quite to the hind margin ; the apical area finely streaked with brown on white 

 ground; the ocelli repeated. 



Under side of secondaries whitish, with an ochraceous tint over the disk and 

 marginal area ; much covered with dark brown abbreviated streaks, which at 

 base and on middle of disk are largely confluent ; the wing crossed by a broad 

 mesial band, the edges of which are dark, the outer ii-regularly crenated or
