only a smoky median shade, which is brightest on the costa, is bent at the end of the 

 cell and is a little emphasized by a short blackish dash in the submedian interspace. 

 In the best marked specimen the ground color is a little brighter. T. a. line is 

 traceable, very narrow, black, irregular, strongly bent outward, so that at the sub- 

 median interspace it forms a sharp tooth whose apex is about at the middle of the 

 wing. Above that point it is outcurved between the veins ; below that point it makes 

 a long inward angulation and is hardly traceable below the internal vein : a few 

 whitish scales may emphasize this blackish line. The t. p. line is brownish, very 

 slender, barely traceable over the cell where it is crenulate, a little better marked 

 below that point, becoming black in the submedian interspace where a short black 

 dash connects it with the t. a. line. The median shade is broad on the costa filling 

 the outer part of the median space, narrowing toward the middle of the wing and less 

 evident toward the inner margin. The s. t. line is marked by two triangular dusky 

 shades, the first of which leaves the apex clear, and has its point at a black spot 

 which almost touches the t. p. line between veins 4 and 5. The second of these 

 comes to a point at a blackish spot which is just below vein 2. The ordinary spots 

 are just traceable, the orbicular is elongate, oval, of the gray ground color, vaguely 

 outlined in brown. The reniform is upright, rather narrow, with a blackish point 

 inferiorly, the outline a trifle paler than the surrounding tint. The fringes have a 

 pale interline. Secondaries a somewhat silky brownish gray, the veins a trifle more 

 dusky and a vaguely marked discal spot. There is a smoky terminal line at the base 

 of the whitish fringes. Beneath, smoky gray, powdery, the secondaries with a small 

 discal spot. Expanse, 1. 40 to 1.50 inches = 35 to 37 mm. 



Habitat: Colorado, Bruce. Glenwood Springs, Col., April 

 30th. Dr. Barnes. 



There are two female specimens before me at this time ; but I 

 have seen others that are like them. The specimen from Mr. Bruce 

 has the markings indicated just sufficiently to enable them to be de- 

 scribed. The specinien from Dr. Barnes, though good, is a little 

 flown and only the dusky median shade seems apparent. The sec- 

 ondaries have a distinct excavation on the outer margin below the apex. 

 Eucalyptera pectinicornis, sp. nov. 



Ground color a dirty clay yellow, more or less powdered with black. Head and 

 thorax without markings, the sides of the palpi more brownish. Primaries with the 

 median space a little more heavily powdered than the rest of the wing, giving it a 

 darker shade. No trace of a basal line is observed in the specimens before me. T. 

 a. line single, blackish, rather close to the base, a little irregular ; but as a whole 

 with an even outcurve. It is rather well defined inwardly ; but tends to become dif- 

 fuse outwardly. T. p. line single, blackish, tolerably well defined outwardly, a little 

 diffuse inwardly. It is oblique to the subcostal, then bends rather abruptly outward 

 over the cell and is afterward a little incurved ; but as a whole nearly oblique to the 

 inner margin. It is followed by a series of lunules of the ground color which are 

 almost indistinguishable, except for the fact that their points indent the t. p. line, the 

 lunules being outcurved. From this point the s. t. space becomes black powdered to
