line outlines the white streak below, and a less well defined one above. 

 The inner half of costa is minutely dotted with brown. The dorsal margin 

 from inner fourth to anal angle is distinctly, marked with seven or eight 

 equally spaced black dots. Ocellic spot, a broad horizontal white bar, 

 with a luteous-white spot above and below it at each end ; above and 

 below the bar is a narrow, short black line, and beyond the two outer 

 spots, two or three black dots. The outer two-fifths of costal margin 

 covering a quarter of the width of wing is a beautiful scroll-work of 

 geminate white lines, edged niternally with black and enclosing three 

 small spots of ground colour ; the outer spot double the width of the 

 middle one and the inner one but little more than an oblique streak. The 

 inner ])air of lines from costa just beyond middle, obliquely to and 

 almost touching oceHic spot, the second pair are shorter and curve around 

 parallel to costal, enclosing middle ground colour spot and joining third 

 pair ; the latter entirely enclose the large outer ground colour spot, and 

 the lower line of this pair separates from its companion and dips down 

 beyond and defining the ocellic spot, thence curves upward into apex, 

 forming a white apical dash. Cilia long, whitish, finely speckled with gray 

 inwardly, followed two narrow fuscous lines. 



Hind wing : Dark smoky-brown, cilia gray, with a darker basal 

 line. Abdomen above and tuft gray, below and legs whitish, tarsi shaded 

 with brown.

Allied to striatana, Clem., spiculana^ Zell., arge7iticostana, Wlsm., 

 and clavana. Fern. Without any other characters a very easy means of 

 distinguishing these species may be found in the scroll-work on costa 

 before apex, which I purpose using later in synoptic tables : the species, 

 all of which have the white or pale median streak, can readily be separated 

 as follows: The white sub-apical streaks o( siriatana are broad, oblique and 

 nearly straight, the inner and apical are geminated, the middle pair entirely 

 separate. In spiculana the white costal streak runs into the inner pair, 

 and there is only one broad white apical dash. The costal streak in argenti- 

 costatia continues clear to the apex as a narrow line, the, streaks are 

 almost obsolete. Clavana, I have not seen, the description only says
