GROTE ON NOCTUID MOTHS FROM COLORADO. 119 



Sadena diversiUneata n. s. 



Female. — This species is well sized, with naked eyes and unarmed 

 tibise. It is purplish gray, and resembles the species of Apatela in that 

 there is a short, black dash crossing the median shade and transverse 

 posterior line (which are very near each other) on submedian space. 

 It resembles the Californian olorina in the shape of the sabterminal 

 line ; this is followed by a blackish shade following its indentations and 

 rendering the usual W-mark apparent. Lines blackish. A short basal 

 dash. T. a. line slightly waved, a little outwardly oblique. Orbicular 

 very small and pale. Eeniform, large or well sized, outwardly indented, 

 pale, shaded with rufous. Median shade strongly angulated ; com- 

 mencing at costa between the stigmata and appearing at the outer and 

 lower extremity of the reniform, thence, approximate to the t. p. line, 

 to internal margin. T. p. line a little notched, nearly even, followed by 

 a, pale gray shade. Hind wings whitish, with a central line and gray 

 borders. Collar with a faint line. Thorax gray : abdomen pale gray, 

 with a black basal tuft. Beneath, whitish gray, with obliterate mark- 

 ings. One specimen expanding 42 mil., ticketed "Manitou, at light, 

 July 14". The species bears a certain resemblance in color to Apatela 

 alharufa Grote. 

 HeliopMla prcegracilis n. s. 



The most slender species of the genus. Eyes hairy. Smaller and 

 slighter than lyallens. Yellow-white, not buff as in pallens, absolutely 

 immaculate. Head and thorax more yellowish. Length of primary 12 

 mil. One specimen, Idaho, "July 0". This species seems slighter than 

 Scuta defecta Grote. 

 Flusia simplex Guenee. 



One specimen. "Arapahoe, 11-12,000 ft. elevation.-' Does not dif- 

 fer from eastern specimens. 

 A7iarta sp. 



One specimen. "Pike's Peak, 13,000 feet, July 12, Packard." The 

 specimen is too much injured to describe. It has a greater admixture 

 of pale, whitish hair, than in any species known to me. The eyes are 

 hairy; ocelli present. The latter character should be observed, since it 

 distinguishes the Heliothid genera from Breplios and allies. 

 Lygrantlicecia jaguarina Guenee.
