Hab. Laggan. British Col., Agnes Lake 6700 feet, Aug. 19, 

 1891, Mr. Thos. E. Bean, Nos. 458, 491, and 9. 



Oncocnemis Colorado n. sp. PI. vi, fig. 5. Resembles chandleri \n color 

 and appearance, and differs from it in color characters mainly in the less 

 contrasting maculation, the very indistinct spots preceding the vague s. t. 

 line, and in that the t. p. line is even and not lunulate. The sexual char- 

 acters are like those of augiistiis, and not like those of chandleri. Ex- 

 pands 34 mm.; 1.35 inches. 



Hab. Park County, Col. Bruce. 



Types are in the United States National Museum, in Mr. Neu- 

 moegen's collection and in the Rutger's College collection. The 

 species seems not uncommon, and it is quite likely that it has 

 been confused with chandleri. Indeed, I have so named it my- 

 self, at first considering the ornamental characters as merely 

 varietal. 



Mamestra languida n. sp. PI. vi, fig. 6. Resembles a small purpnrissata, 

 in general appearance. Differs in the absence of the t. a. line, by having 

 the t. p. line even, rather than lunulate, by the darker shade extending 

 over the costal region and through the median cell to the t. p. line, and, 

 finally, by the whitish secondaries. Expands 37.5 mm.; 1.50 inches. 



Hab. Colorado. Bruce, No. 261. 



The resemblance to purpnrissata extends to the antennal struc- 

 ture and to the relative proportion of thorax and abdomen. In 

 ornamentation the resemblance becomes less striking on critical 

 comparison. 



Mamestra segregata n. sp. PI. vi, fig. n. Very dark purplish brown, 

 verging on blackish; a more reddish shade through the centre of the 

 wing, the lighter regions relieved by gray povvderings. Transverse lines. 

 all present, black or blackish, geminate, gray filled. Median lines ap- 

 proximate in the submedian interspace, connected by a black streak from 

 the end of the claviform. Ordinary spots large, gray powdered, orbicular 

 oblique, sometimes incomplete above. S. t. line yellowish sinuate, de- 

 fined by black scales. Secondaries deep smoky-brown. Expands 36 

 mm.; 1.43 inches. 



Hab: Laggan, British Col., at light, May i3th and lyth. 

 Bean, Nos. 447, 531, S and 9. 



Differs frpm all the described species by the combination of 

 very dark brown color, connected median lines and even s. t. 

 line. 



Agrotiphila maculata n. sp. PI. vi, fig. 7. Black and whitish gray, the 

 markings contrasting. The patagiae are gray margined, and the dorsum
