NO. 1283. REVISION GF SOME NOCTUID MOTHS-SMITTL 199 



I ciui not place the variety te.vana Morrison. I have nothino- so small 

 as :^!t mm. in expanse, and nothino- in which the lines on- the collar ai-e 

 not at least traceable. The essential differences as pointed out by Mr. 

 Morrison are: "They expand only 2!t mm.; the collar lacks the bhick 

 trans\'(>rse line of the typical form; the oround color is clear and 

 whitish, not becoming- suffused with reddish or dark ochreous before 

 the terminal space.'' 



Mr. Grote in describing- ll<jat<( refers to this variety as if he thought 

 Mr. Morrison might have had such a form as his new species before 

 him, but this seems hardly credible. 



LEUCANIA IMPERFECTA Smith. 

 Leucania imperfecta S.mitii, Trans. Am. Eiit. Soc, XXI, 1894, p. 76. 



Ground color a dull luteous, shaded with smoky or blackish. The 

 head may be of the pale ground or of the smoky tint. Collar with three 

 purplish black transverse lines; patagia? blackish at base of primaries, 

 tending to the pale ground on the disk. Primaries darker over the 

 costa, through the middle of the wing, along the inner margin, and in 

 the terminal space before the apex. This leaves the pale ground as a 

 long shade through the cell from base to apex and through the sub- 

 median interspace from base to the transverse posterior line. The 

 shadings are all quite even and not obviously strigate. Median vein 

 accompanied b}^ a blackish streak which may or may not darken it to 

 the end. At the branching there is always the angular white spot, 

 emphasized by a preceding black dot. In one specimen the vein is 

 narrowly white throughout. The other veins may or may not be 

 partly white marked. There may be a series of small black terminal 

 dots and a yellowish line at the base of the fringes. 



Secondaries, transparent, somewhat pearly white at base, the veins 

 smoky or blackish; a somewhat diffuse, smoky margin, variable in 

 width. Fringes with a yellowish line at base. Beneath, primaries 

 gray, powdery, the disk tending to and sometimes all blackish. Sec- 

 ondaries white, powder}" over the costal and apical area.

 cahua Mountains, Arizona, June 26 (Hubbard); Wilgus, Cochise 

 County, Huachuca Mountains, and southern Arizona (Barnes). 



Seven examples from so many localities in Arizona indicate that it 

 is not really a rare species. There seems to be little variation except 

 in size, and that is not sexual, since the largest and smallest examples 

 are both males. 



In the uiale the sexual tuftings are not very prominent. On the 

 anterior legs thefenjora have a moderate scale fringing at base, becom- 

 ing shorter toward tip; the tibia is a little scale thickened outwardly. 

 On the middle leg the femoral fringe is a little longer, the tibia is
