terminal line pale, of the usual irregular shape, preceded opposite the cell by 

 cuneiform brown marks ; fringes concolorous. Hind wings fuscous in both 

 sexes with paler fringes and paler at the base with an indistinct median line. 

 Thorax and abdomen strongly tufted ; the former concolorous with primaries, 

 the tegulae blackish. Underneath paler, the hind^wings with a distinct discal 

 mark.

 mens with the numbers 10 and 20 on red labels). 



Hadeua albiua Orote. 



? . — Two specimens of a species closely allied to H. castanea, similarly sized 

 and diflFering as follows : The ground color of the wing is paler, somewhat 

 ocherous and this tint obtains especially on the subterminal space. The orbic- 

 ular is larger and open to costa ; the reniform is washed with pure white cen- 

 trally and the claviform is larger. The terminal space is marked with the paler 

 tint on each side of the veins, interrupting vividly the fringes. The disc of 

 the thorax and the tufts are also quite pale ; the hind wings are paler and more 

 yellowish with the median line more distinct. Beneath paler, with a more red- 

 dish tint and with the discal spot less evident than in H. castanea. The tufts 

 on the abdomen are equally prominent with those of II. castanea, &nd the color 

 has the reddish staining of its ally. 



Exjjanse, 46 m. m. Hahitat, California (Mr. Behrens, No. 78, 

 Sauzalito, May 15). 



Hadena curYata Grote. 



S 9 . — Two thirds the size of the preceding species, but allied by the strongly 

 tufted thorax and abdomen. The usual depression of the external margin of 

 the hind wings opposite the cell is here exaggerated, and forms a strong spe- 

 cific character to judge by its perfect uniformity in the four specimens before 

 me. Blackish wood brown, very dark. Basal and t. a. lines distinct, black, 

 geminate with included pale shade ; t. a. line a little jagged superiorly, arcuate 

 in its general course. Extra basal space shaded with deep black. Orbicular 

 concolorous, blacK ringed, moderate. Keniform usually concolorous, sometimes 

 shaded with ochery brown which always stains the approximate t. p. line op- 

 posite the spot, and this stain may be mistaken for the reniform itself. Sub- 

 terminal line with the usual indentations, well removed from the margin, pale. 

 Veins marked with deep black terminally and more or less distinctly. A ter- 

 minal pale line before an even dark one at the base of the dark obsoletely pale 

 dotted fringes. Hind wings blackish fuscous, silky, paler at base with pale, 

 somewhat ruddy interlined fringes and a faint transverse line. Beneath pale 

 with a purply or ruddy hue, coarsely irrorate with black and with a common 

 line and black discal spots. Beneath body and legs like tho wings ; a stigma- 

 tal black abdominal line. Above head and thorax like primaries, touched with 

 brown and with obsolete black lines on the tegulae and collar.
