Smoky black, superior part of basal space and a lar^e irrc<;iilar and 

 ill-detined costal patch over t. p. lino carneous or rather pale red brown ; 

 ordinary spors Avith a similar tin<;e and narrow annnU of same color. 

 Cell of a dee|)er black. Lines geminate, basal line distinct; t. a. line 

 twice outwardly curved, oblique; t. p. line rather even, illy defined 

 parallel with outer mar<;in; s. t. line pale, punctiform or lunate, very 

 regular; (^lavifona wanting; renilbrm rather narrow, somewhat irregu- 

 lar, elongate; orbicular narrow, oblique, oblong. Secondaries smoky 

 fuscous. Beneath smoky, with a blackish comiiu)n line; secondaries 

 paler toward base, powdery, discal lunule present. Collar brown, 

 thorax mixed with red brown. 



Expands 37-41"""; 1.5-l.Go inches. 



Habitat — United States, east of the Rocky Mountains. 



A very well marked species, easily recognizable by the dark color 

 and the contrasting red brown blotches. The primaries are unusually 

 obtuse. 



The initial black patches of s. t. line are, owing to the dark ground 

 color of wing, rather less distinct than usual, but yet always evident.

" S. Allied to ^. hicarnea Gn., smaller and distinguishable by the 

 evenness of the t. p. line. Fore wings dead brownish black. T. a. 

 line rigidly oblicpie to siibmedian fold, not rounded as in its all\ , and 

 with a less prominent tooth on internal margin. A very faint yellowish 

 shading to the line an<l also on the costa at the inception of t. p. line, 

 where ^1. hiainwa is strongly marked witli carneous. T. ]). line sha[)ed 

 as in its ally, but even, geminate, the inner line not scalloiied ; the coin- 

 l)onent lines include a pale shading. Disc velvety black between the 

 narrow stigmata, which are concolorous with the dead black of the wing. 

 A black shade at base below the median vein. All the transverse lines 

 geminate; the inner of the basal and t. p., and the outer line of the t. a., 

 marked with velvety black. In one specimen there is an absence of the 

 velvety black shades; this one is in iini)erfect condition and allows of 

 no certain description, llind wings yellowish gray, paler than in hicarnea, 

 with a noticeable terminal darker shading. Beneath witli common line 

 and strong lunule on secondaries. Head dark brown on vertex, with 

 pale marginal lines; terminal palpal joints pale; collar brown, with a
