Botis plumbosignalis, n. sp. 



Expanse of wing, 21 mm. Head and palpi yellowish white above, pure white 

 beneath. Labial palpi fawn colored on the outside. Thorax and fore wings sulphur 

 yellow, the former with a rust-colored stripe on the sides from the eyes to the wings 

 and extending a short distance on the costa. The orbicular spot on the middle ot 

 the cell is small and round, of a dark rust red color and overlaid with lead colored 

 scales. The reniform spot on the end of the cell is similarly colored and extends 

 across more than the width of the cell. A stripe of the same width and color as the 

 reniform but forming an obtuse angle with it, extends across to the hinder margin of 

 the wing, and another extends from where this joins the reniform obliquely up to 

 near the apex, the whole forming a Y-shaped mark. These stripes are somewhat 

 diffuse on the outside, and the outer transverse line is distinct only between the upper 

 parts of the Y. The inner transverse line extends obliquely out and down from the 

 costa to the median vein, where it forms an angle, and then extends to the hinder 

 margin, forming another angle on vem one. Another similar line runs parallel but 

 outside of it, from the median vein to the hinder margin, forming a lunule between 

 the veins and these two lines together give the appearance of the figure 8 beneath the 

 orbicular spot. The fore wings are rather narrow and slightly falcate. The hind wings 

 are white, slightly tinged with sulphur yellow on the outer margin, and there is a 

 minute brown spot on the anal angle with traces of one or two more on the surface 

 of the wing, an indication of a transverse line. The underside of the wings is whitish 

 with the markings of the upperside reproduced in brown. 

 Described from three examples from Colorado. 



Lipocosma fuliginosalis, n. sp. 



Expanse of wings, from 13 to 15 mm. Head, thorax and fore wings, snow 

 white ; the latter overlaid, except on the base, at the apex and narrowly along the 

 costa, with dark brown or soot color. The outer crosshne which is darker than the 

 wing starts from the outer fourth ot the costa, makes an outward angle at first, then 

 curves outwardly beyond the end of the cell, then makes another outward curve and 

 ends at the outer fourth of the hinder margin. There is a faint trace of another line 

 crossing the middle of the wing. The outer margin has a row of black dots. The 

 fringe is sordid and cut with whitish. The hind wings are whitish on the costal half, 

 and discolored more or less on the rest of the surface with soot-color which forms a 

 line across this part of the wing beyond the middle. On the inside of this line above 

 the anal angle there is a white spot and a tuft of black scales on the innerside of the 

 spot. The basal joint of the abdomen is white and the rest sooty-brown. The 

 markings of the upperside are repeated and there is a plain discal spot on each of 

 the wings. 



Described from four examples, from Maine, Ontario and Illinois. 



Hydrocampa proprialis, n. sp. 



Expanse of wings, 10 to 19 mm. Head, thorax and fore wings, dark brown. 

 The reniform spot at the end of the cell of the fore wing is while, and ihere is a more 

 or less prominent white spot on the costa above it. The inner transverse line is
