AMERICAN LEPIDOPTERA. 73 



Acoiitia schwarzii n. sp. 



Head, thorax and abdonieu white. Primaries white and gray mottled in the 

 basal space; the t. a. line white, indented in the subniediau interspace, gray 

 margined. Beyond this the white shade extends below the median vein, to the 

 middle of the median space; above, it extends to the middle of the s. t. space 

 where it is abruptly and squarely cut off. A gray cloud, indicating the median 

 shade on the costa, tends to cut off a quadrate ante-apical patch. The inner por- 

 tion of the gray shading tends to brown, a rather feebly defined band indicating 

 the median shade. The s. t. line is traceable as a slender, irregularly denticu- 

 late blue line. Apex brown. S. t. line unusually close to the outer margin, 

 marked by a few black and white scales toward apex ; white and sinuate below 

 middle. Fringes white, interlined with black toward apex. Orbicular wanting. 

 Reniform an oval gray spot. Secondaries white, with a variably broad outer 

 margin, darker in the female. Beneath, primaries black, margins narrowly 

 white, fringes white. Secondaries white, with a narrow dark outer margin. 



Expands 25-26 mm. = 1.00-1.05 inches.

One male and one female are at hand and resemble each other 

 generally. The variation is in the amount of the gray shading in 

 the wings The primaries are moderate or rather broad. Sec- 

 ondaries with vein 5 weaker than the others, from a spur at the 

 end of the cell. Veins 3 and 4 branch just beyond the end of 

 the cell. 



Acoiitia arida n. sp. 



Head and thorax white or creamy ; abdomen a little yellow tinged. Primaries 

 white or creamy from base to near the middle of median space, then obliquely 

 curved toward costa to the middle of the median cell, thence outward, nearly 

 parallel with the costa to the middle of the s. t. space and there abruptly termi- 

 nating against the dark olivaceous apical space. The basal space is variably gray 

 clouded. T. a. line gray marked on the costa, then by an incurved yellow cres- 

 cent in the middle of the wing. The lower outer portion of median space, ex- 

 tending outward to s. t. line and curved upward toward apex, is leaden gray, 

 yellow or olivaceous shaded outwardly, the apex brown tinged. A broad gray 

 or olivaceous shade extends from costa above the reniform toward the gray por- 

 tion of the median space, cutting off, in whole or in part, a quadrate white patch 

 on the costa before the apex. T. p. line irregular, denticulate, blue, slender, 

 more or less obviously geminate. S. t. space more or less l)rown tinged. S. t. 

 line violet through apical patcii, yellow or whitish and broadening inferiorly, 

 inwardly and upwardly augulate opposite the hind angle so as to reach almost to 

 the end of the median vein. The usual series of black terminal dots or marks is 

 wanting, and there is a paler line not quite terminal. Fringes olivaceous or vio- 

 laceous at hind angle and at apical third, else whitish or yellowish. Orbicular 

 wanting. Reniform an obscure leaden gray, somewhat oval spot. Secondaries 

 in the male soiled white, a little darker outwardly ; in the female smoky, a little
