ACRONYCTA LITURATA, new species. 

 (Plates XIII. fig. 8, female adult; XXI, fig. 21, male geuitalia.) 



Ground color a pale powdery ash gray, more or less suffused with 

 smoky. Head with a brown line below and another above the anten- 

 nae; a blackish line crosses the middle of the collar, and the edges of 

 the patagiae are more or less black marked. The primaries have all 

 the markings traceable, but rather obscured. Basal line is geminate, 

 brown or black marked on the costa only. The transverse anterior 

 line is geminate, brown or black, outwardly oblique, irregular between 

 the veins. The median shade is narrow, obscure outwardly; oblique 

 from the costa through the reniform and then irregular, obliquely 

 inward to the hind margin. Transverse posterior line geminate, brown 

 or black, the inner portion of the line less defined, the included space 

 white 01- nearly so, the outer line slender and denticulate on the veins. 

 The subteimiual line is white or nearly so, very strongly dentated, 

 interrupted opposite the cell and in the submedian interspace. The 

 terminal space has, in the interspaces, blackish markings, more or less 

 evident, and a series of black terminal lunules, beyond which the 

 fringes are cut with black or brown. There is a more or less distinct 

 basal black streak which extends through the transverse anterior line 

 and almost to the middle of the wing. It is accompanied by a more 

 or less obvious blackish shade which continues through the submedian 

 interspace to the outer margin. It is sometimes sharply interrupted at 

 the median line, leaving the space between it and the transverse pos- 

 terior line of the paler ground color. There is also a blackish streak 

 from the reniform outwardly, which becomes broader and more difiuse 

 on the margin. In a vague sort of way the middle of the wing between 

 the ordinary spots and to the longitudinal shade is also a little more 

 dusky, l^he ordinary spots are traceable; the orbicular being rather 

 distinct, white, outlined in black and centered with brown ; the reni- 

 form may or may not be outlined by black scales, and there is usually 

 a blackish lunule in the center. Secondaries white in the male, a little 

 soiled at the edges ; in the female the soiling extends farther toward 

 the base of the wing. Beneath, more or less powdery; the primaries 

 sometimes smoky, the ordinary outer lines and discal spots variably 

 evident. 



Expanse, 1.60 to 1.68 inches (40 to 42 mm.).
