SMITH, NEW NOCTUID^ 99 



Habitat: Palmerly, Cochise County, Arizona, July and August. 



Eight examples, mostly in good condition, all very much alike and all 

 females. The reference to Euxoa is in the sense in which that genus is used 

 by Hampson. The frontal structure in this species is as in Chorizagrotis, 

 but the body is not depressed. As there are no males, the antennal struc- 

 ture of that sex cannot be used as a guide, and the generic reference must be 

 provisional. The species is altogether unlike any other form known to me 

 from our fauna, and the peculiar course of the median lines should serve as 

 a means of recognition. 



Ufeus electra nov. sp. 



Ground-color dull chocolate-brown. Head and thorax with dark hair inter- 

 mingled. Primaries so densely set with long black hair as to give the whole a 

 blackish appearance. A black basal streak in the sub-median interspace extends 

 almost to the middle of the wing. Another streak extends, with little interruption, 

 through the cell and beyond it to the outer margin. T.a. line lost. T.p. line 

 outwardly bent from costa, obscure, blackish, with small outward extensions on 

 the veins. A series of black inter-spatial marks at base of fringes, becoming longer 

 toward the apex. Secondaries dull yellowish, smoky, with an overlay of black hair; 

 a distinct discal lunule and a well-marked extra-median shade line. Beneath, 

 reddish gray, powdery, darker at the margins on primaries; secondaries with an 

 obvious extra-median line and a distinct discal lunule. 



Expands 1.55-1.65 in. = 39-41 mm. 



Habitat: Oregon. 



Two female examples, without date or name of sender. Evidently 

 they are electric-light captures, and more or less defective ; but their differ- 

 ence from the allied forms is obvious. The species is nearest to plicatus 

 in type of maculation, and it is quite probable that in some specimens, traces 

 of the discal spots will occur. 



TJfeus hulstii nov. sp. 



Ground-color rather hght red-brown. Head and thorax without markings. 

 Primaries with fine black hair, the veins a little darker. T.a. line distinct, single, 

 blackish, outwardly oblique, with three distinct outward angulations, — one on the 

 sub-costa, one below the median and the other on vein 1. T.p. line single, black, 

 followed by a slightly paler shade, evenly and moderately outcurved, with short 

 outward spurs on the veins. A series of small black terminal dots. Fringes cut 

 with yellowish. Secondaries silky gray with a reddish tinge. Beneath, very pale 

 pinkish gray, immaculate. 



Expands 1.38-1.42 in. = 34-35 mm. 



Habitat: Black Hills, Wyo. ; Stockton, Utah, July 22. 



Two male examples. One of them is from the Hulst Collection, with-
