258 AMERICAN LEPIDOPTERA. 



thorax grayish. Primaries with ornamentation well defined. Costal 

 area paler to the reniform ; sub-costal whitish to the orbicular. Basal 

 line marked by geminate blackish marks on costa and in the sub- median 

 interspace ; a narrow blackish iine connecting the lower spots with the 

 t. a. line. T. a. line geminate, blackish, defined only in the sub- 

 median interspace. T. p. line marked by geminate spots on costa 

 above reniform, outcurved closely over this spot, then rather evenly 

 oblique, single, broken, to the inner margin. S. t. line pale, powdery, 

 irregular, broken, emphasized by the series of preceding black spots, 

 some of which are sagittate ; outwardly a little indented on veins 3 and 

 4, and a little less on veins 6 and 7. A narrow, black, slightly lunate 

 terminal line, followed by a yellow line at base of fringes. Claviform 

 a little darker than ground, black edged, extending across the median 

 space and touching the t. p. line. Cell around and between the ordi- 

 nary spots a little darker. Orbicular oblong, open to the costa, drawn 

 to an angle posteriorly, paler than ground, a whitish line within the 

 black defining edge. Reniform narrow, kidney-shaped, the inner 

 edge drawn out into a little tooth or angle toward the outward angle 

 of orbicular, narrowly black-ringed, within this a somewhat diffuse 

 whitish shade ; centre a little paler than ground, with a rusty yellowish 

 outer line. Veins 3, 4, 6 and 7 are dark marked and a little rayed in 

 appearance. Secondaries smoky, veins a little darker, fringes white. 

 Beneath white ; primaries smoky on disk, else coarsely powdered with 

 blackish ; veins dusky and a dusky discal lunule ; secondaries pow- 

 dery along costa, with an extra-median powdery line and a small discal 

 spot. 



Expands, 1.50 inches = 37 mm. 



Hab. — Colorado (Bruce). 



A single good female specimen from the Bruce collection. 

 It is another one of those forms easily confused with brevi- 

 pemiis, but not so robust, and with proportionately smaller 

 body and more ample wings. The form of the ordinary 

 spots is characteristic and unlike that of any other species 

 known to me. 



Euxoa ponclia n. sp. 



Ground color a very pale whitish }'ellow, tending to creamy. Head 

 with a blackish transverse line inferiorly, palpi dusky at sides. Head 

 and thorax otherwise without maculation. Primaries with all the 

 maculation broken and marked by dusky powderings, more complete 

 in the female than in the male. Basal line geminate, marked on costa 

 and below median vein only. T. a. line geminate, the parts about 

 equally developed, upright as a whole, slightly outcurved in the inter- 

 spaces. T. p. line geminate, parallel with outer margin, almost rigid;
