44 AMERICAN LEPIDOPTERA. 



gray and black, especially black along the edges. Before the middle spot the 

 outer half of the dark basal area is similarly dotted with black. The costa is 

 marked with fine white lines its extire length, there are six in the basal area, 

 four over the middle dorsal white spot, beyond these are four pairs of geminate 

 white lines, becoming shining gray below costa and obliquely extending to the 

 upper edges of the two outer dark and white dorsal patches, the gray streaks are 

 on an obscure dark brown ground. The geminate streaks are separated by clear 

 brown wedge-shaped streaks, the widest separating the outer geminate lines from 

 a brown lunate apical spot, the latter is separated by the outer end of a costal 

 line, with a similar brown streak between ocellic spot and termen. Cilia white 

 at angle, with a fine marginal gray and brown line, which increases above middle 

 and overspreads the cilia, becoming smoky black at apex. 



Hind wing: light shining fuscous, cilia paler; underside the same on lower 

 half, becoming much darker above. 



Underside forewing: smoky brown, with white geminate costal spots.

Tliiodia daracana sp. nov. 



Expanse 16-18 mm. 



Head : blackish-brown over eyes, cinereous above and in front ; palpi grayish- 

 brown ; antenna and thorax fuscous; abdomen fuscous, anal tuft yellowish ; legs 

 brownish-white, dusted and banded with shades of darker brown. 



Forewing: fuscous, heavily overlaid with white, giving a gray appearance. The 

 white scales are closer together, forming an obscure fascia on lower half of wing 

 beyond middle. The ocellic spot is white, with shining white scales on side, 

 and two short superimposed horizontal black lines. Between middle and apex 

 the costa is marked with five pairs of (geminate) lines, the three outer pairs run 

 together beneath the subapical spot, sending a spur into termen beneath apex, 

 below the costa these lines are slightly irridescent. The geminate lines are sepa- 

 rated by darker fuscous-brown spots on costa, and there is a small triangular 

 patch of the ground color, nearly free from white scale on dorsum below ocellus. 

 (Jilia gray, speckled with fuscous and with a narrow white outer line. 



Hindwing: smoky brown, lighter above dorsal margin; underside grayish, 

 fuscous, with a purplish reflection. 



Underside forewing: fuscous, paler below. 



Ten specimens : Placer Co., Cal, April 20th to May 1st, A. H.

Thiodia raracaiia sp. nov. 



Expanse 11-14 mm. 



Head : cream-white, shaded with light brown on tufts above eyes; palpi cream- 

 white, with a dot of fuscous at base and one at middle of second joint outside; 

 antenna cream-white, shaded with fuscous in front; thorax salmon-pink, ochre- 

 ous in front; abdomen fuscous, anal tuft pink ; legs whitish, banded and dusted 

 with brown and black. 



Forewing: light reddish-ochreous in the brightest specimens to a reddish-fus- 

 cous in the darkest. The color is darker in the middle of the wing and palest 

 below costa before middle and at apex. The ocellus is the most consi)icuous 

 marking, it reaches to middle of wing, and is as broad as high, cream-white in 

 the middle, with vertical side bars shining white, on the dull white are two hori-
