paler than the ground color, but in some cases there is very little or no differ- 

 ence. Secondaries white, black powdered, with a vague outer transverse line 

 and a distinct, marginal line. Beneath white, powdery, both wings with a 

 blackish discal spot. Expands 30-35 mm. ; 1.20-1.40 inches. 



Hah. — Glenwood Springs, Colo., September and October, Barnes ; 

 ten specimens. 



In the series before me very little variation is observable, except 

 in the somewhat lighter or darker ground color, and the relatively 

 more or less distinct ornamentation. None of the specimens are 

 ])erfect, and all of them bear the ear marks of electric light cap- 

 tures. The males at first sight have quite a strong habital resem- 

 blance to Charadra jyalata Grt. 



C'liytoiiix coniiefta n. sp. (PI. iv, fig. 2) — Ground color a dull luteo-fus- 

 cous, powdery. Head and thorax concolorous, immaculate. Primaries with the 

 basal space and the median space below the dash connecting the median lines, 

 dark smoky brown. Basal lino single, black, distinct, extending to the short 

 basal black dash. T. a. line black, single, a little outwardly oblique, even to the 

 median vein, then dentate to the hind margin. T. p. line single, black, rather 

 slender toward the costa, slightly irregular, forming one distinct angle opposite 

 the median vein : below this point a distinct white line follows the black, and 

 there is a somewhat diffuse powdering beyond that point. The s. t. line is frag- 

 mentary, very irregular, marked toward the apex by white scales, hardly dis- 

 tinguishable below that point. There is a narrow lunulate terminal line. A 

 fine brown median line is fairly well marked, and makes a long outward angle 

 below the reniform. A narrow black line connects the median lines, defined 

 rather strongly by the contrast between the dark shade below it and the unusually 

 light yellowish tinged space above. In this pale shade the large ordinary spots 

 are evident, though by no means well defined. The orbicular is round, incom- 

 pletely outlined by brown scales. The reniform is yet less well defined, and is 

 kiduey-shaj)ed. Between veins 4 and 5, a black line extends from the cell to the 

 outer margin. Thesubterminal space is more or less powdered with white scales, 

 and similar scales are less abundantly scattered in other parts of the wing. Sec- 

 ondaries smoky brown with greenish white blotches toward the outer margin ; the 

 fringes being of tlie same pale shade, but based by a series of blackish lunules 

 Beneath brownish gray, powdery, primaries with an outer transverse dark line 

 and a pale discal lunule; secondaries wiih a broad subbasal line, an extraniedian 

 denticulated line, a submargiual broad dusky shade, and a narrow broken ter- 

 minal liiie Expands 37 mm. ; 1.50 inches. 



Hub. — Texas, Graef. 



A single female specimen only. The species is rather closely al- 

 lied in appearance to C. soisilis Grote, but differs markedly in de- 

 tail.-^. There will be no difficulty in recognizing it, I think. 



Set;igi*olis tierrifica n. sp. (PI. ii, fig. 2) — Ground color of head, thorax 

 and ju'lmaries :i dirty pale luteous, with a more or less prominent admixture of 

 whitish scales; collar with a rather vague brownish transverse line, else thorax
