to depend somewhat upon locality, the palest specimens coining- from 

 northern ^e\v York, while the darkest forms are confined to the Pacific 

 Coast. 



The structural features of the species have been previously referred 

 to and need not be again rehearsed here. 



Hypena decorata, Siiiith. 

 1884. 8iiiitli, liiill. Hklu. Eutoinoloj;ical Soc, VII, 4, Hijpcna. 



Ground color a rich red brown with bluish gray relieving scales. 

 Head and thorax concolorous, the latter speckled Avith blue scales in 

 the female. Abdomen like the secondaries. Primaries quite mark- 

 edly transversely strigate, many of the strigic contiiuied almost 

 entirely across the wing. The subterminal space is quite contrast- 

 ingly blue gray just beyond the transverse posterior line; but becomes 

 of the brown base before the subterminal line. Transverse anterior 

 line pale, outwardly marked with brown, with an acute outward tooth 

 on the median vein. Transverse posterior line pale, preceded by black, 

 very even, obli({ue, a little sinuated, with a marked outward bend in 

 the submedian interspace and a well-marked inward tooth on the inter- 

 nal vein. Subterminal line punctiform, the spots black, followed by 

 white scales, as a whole a little sinuate. A lunate blackish terminal 

 line preceded by whitish scales. Beneath the pale apex is a distinct 

 deep brown oblique shade, extending nearly half way through the 

 subterminal space. Orbicular a round patcli of elevated black scales, 

 lieniform a lunule of elevated scales. A distinct black line sur- 

 mounted by a paler shade nearly connecting tlie two spots. Second- 

 aries yellowish fuscous, even, with a brown terminal line and paler 

 yellow fringes. Beneath, powdery yellowish, the apices brow^n, both 

 wings with a brown extra-median line; primaries with an incomplete 

 subterminal line, which is white dotted near the costa; secondaries 

 with a discal spot. 



Expanse of wings, 31 to 34 mm. = 1.25 to 1.35 inches.

This si)ecies was collected by Mr. Ily. Edwards, ;ind 1 have seen no 



specimens other than those from which I originally described. Only 



tlie female is before me at present, but the male differs only in the 



more even color of the primaries, the contrasts being less marked. 



The character of the subterminal line further relates this species with 



H. hiimiiU, while in. the very distinctly scalloped fringes the species is 



unicpie, differing from all others of our forms. There is little chance 



of mistaking it. 



Hypena californica, Uthr. 



1870. Belli", Trans. Am. Entomological Soc, III, 23, Hjipenu. 



Ground color a somewhat pale yellow, more or less shot with red 

 brown, varying somewhat in shade. Head and thorax concolorous, 

 the latter with the disk often darker. Abdomen concolorous with the 

 secontlaries. Primaries with the i)ale color predominating in the 

 female, the brown markings contrasting. In the male the wing is
