new species of North American Tortricidse. 503 
along the dorsal margin ; there is an elongate spot in the base of 
the cilia immediately below the apex, and a larger and more 
conspicuous one scarcely below the middle of the apical margin, 
the latter plainly visible on the underside ; cilia white, tipped at 
the apex with greyish fuscous. Exjy. al., 26 mm. Hinchoinga 
white, with a slight smoky brown shade, especially on their outer 
half ; cilia shining white. A bdomen white. Legs white, with a 
slight brownish tinge. 
Type. Mus. Wlsm. 
Hah. Colorado — Loveland. A single specimen of this 
very distinct species received from Mr. W. G. Smith 
in 1891. 
Psedisca ragonoti, sp. n. (PL XII. fig. 9.) 
A ntennce very slightly pubescent rather than ciliate ; white, 
slenderly annulated with mouse-grey. Palpi white, tinged with 
mouse-grey at the outer sides ; densely clothed to the apex. 
Head creamy white. Thorax white, slightly grey shaded. 
Forewings pale mouse-grey, with shining white blotches ; the 
extreme base narrowly shining white, as also the extreme edge of 
the dorsal margin near the base ; a pair of large irregular shining 
white spots on the basal third, obliquely placed, the first on the 
middle of the wing reaching to the lower edge of the costal fold, 
the second beyond and below it touching the dorsal margin ; a 
very oblique shining white band from below the costa, before the 
middle, crosses the wing obliquely, and is bent back at its outer 
extremity to the middle of the dorsal margin ; from near its outer 
angle a curved shining white streak bends outwards, reverting to 
the anal angle and throwing out a branch to the apical margin 
below the apex ; above this curved streak, on the outer half of the 
wing, is a quadrate subcostal shining white patch, branching 
obliquely outward to the costal cilia, a short shining white apical 
streak beyond it ; cilia white, with a mouse-grey shade running 
through them at the apex, and below the middle of the apical 
margin. Underside smoky grey, with three white costal spots 
towards the apex. Exp. al., 23 mm. Hindvnngs pale fawn-grey ; 
cilia white, with a grey shade along their base. Abdomen fawn-
