scarcely raised; palpi oblique, thickened with scales, the end joint

Black, the fringe of both wings white. Beneath, the tongue, basal 

 joint of palpi, base of fore wing running along costa and basal half of 

 costa of hind wing bright orange yellow; fringe as above. Expanse, 

 43 mm.

 ber, 1909 (R. Miiller). 



Mr. Schaus kindly compared this species in London and labeled it 

 "Arctiid, quite new;" but it seems to me to be rather a noctuid, as 

 vein 8 of the hind wings makes only a short anastomosis with the 

 cell. 



Genus GERRA Walker. 



GERRA SOPHOCLES, new species. 



Fore wing brown with a white oblique costal shade before apex; 

 reniform and orbicular Ughter brown; inner and outer lines very faint, 

 dark; a light reddish submarginal row of joined spots bordered within 

 with red-brown. Hind wing and abdomen dull gray-black, the 

 fringe white. Beneath shining leaden black, the veins black; fringe 

 of fore wing partly white; bases of both wings, tongue and base of 

 palpi bright orange yellow. Expanse, 34 mm.

GERRODES MINAT.a;A, new species. 



Thorax and fore wing leaden gray, with brown streaks; an oblique 

 whitish shading from before apex into cell, crossed by the brown 

 streaks; a brown outer line parallel to outer margin above curves in 

 below cell and jouis the other streaks; closely following it a fine white 

 line also curves inward and becomes a broad white band below cell, 

 not reaching base ; a slender whitish Hne beyond in the gray terminal 

 space; a leaden Hne before the fringe. Abdomen yellow with a 

 dark dorsal stripe. Hind wing orange-yellow with a rather narrow 

 brown-black border; fringe whitish. Beneath both wings yellow 

 with gray borders becoming black inwardly, the fore wing with an 

 irregular discal mark. Expanse, 53 mm. 



Type.—Usle, No. 13913, U.S.N.M., Zacualpan, Mexico, June, 1910 

 (R. Miiller). 



Allied to Gerrodes longipes Druce, but differing in the presence of 

 the white bar and in the outer line, which is erect and not followed 

 by a distinct second line.
