oval, oblique; wings broad, maculation clear and distinct atlantica.

 orous desperata. 



Wings narrower; fuscous brown; orbicular moderate, transverse lines more 



distinct canadensis.

Mamestra farnhami Grt. 



187,5. Grt., Buff. Bull., i, 103, PI. 3, f. 2; Maviestra. 



Fuscous brown, basal and s. t. spaces with a distinct violet shade. 

 Lines black, geminate, included space paler. Basal line present. T. 

 a. line upright, angulate between veins. T. p. line forming an obtuse 

 augle opposite the reniform, then scarcely lunulated in an almost rigid 

 oblique line to the margin. S. t. line narrow, yellow, distinct, arising 

 from the pale apical patch, running thence obliquely to hind margin, 

 iaterrupted on veins 3 and 4 by prominent sharp teeth, which touch 

 the outer margin and form a prominent, sharply cut W. Terminal space 

 somewhat darker ; apical pale patch and s. t. line preceded by black, 

 sagittate dashes. Claviform concolorous, large, black-margined. Ordi- 

 nary spots rather narrow, concolorous, black lined, and with an inner 

 pale annulus. Surmounting the claviform, and from the lower portion 

 of the orbicular, is an oblique, pale, creamy, yellow shade, similar to 

 that in Prodenia. There is a row of terminal black lunules. Second- 

 aries fuscous, towards base paler; a dusky, discal lunule, and row of 

 blackish terminal lunules. Beneath, powdery, purplish, with exterior 

 common line and discal dot. Head and thorax purplish violet, the 

 latter with distinct fore and aft tuftings. Abdomen fuscous, basally 

 tufted. 



Expands 37-42'"'" (1.50 to 1.G8 inches). 



Habitat. — Colorado. 



This uniquely marked species has a strong resemblance to Eupsepho- 

 pccctes and Prodenia. Its bright colors and unique maculation make it 

 easily recognizable. I have seen only a single female (type) specimen 

 from Mr. Hy. Edwards's collection. Mr. Grote, who had both sexes 

 before him, says the male anteunjc are simple, very shortly ciliate 

 beneath. In his specimens the ground color seems to have deeper 

 " blackish, with a dark-green cast," while the violet shadings Mr. Grote 

 calls " purplish."
