new species of North American Tortricidse. 505 
commences at the base below the costa, dilated outwards and bent 
downwards at one-third, terminating in an acute point about the 
middle of the wing, at its base it is diffused downwards across the 
fold, almost blending with a sinuous band of the same colour, 
commencing near the middle of the dorsal margin, thence looped 
outwards and upwards, reverting nearly to the anal angle and 
deflected towards the apex parallel with the apical margin ; on the 
outer half of the costal margin are two short shining white 
festooned bands, the first deflected obliquely outward, the 
second equidistant between it and the apex ; the apex, apical 
margin, and cilia are white, thickly speckled with grey scales. 
Underside with three or four pale costal spots beyond the middle. 
E^rjj. al, 20 mm. Hinchvings pale fawn-grey ; cilia whitish. 
Abdomen and Legs creamy whitish.

This appears to be a convenient opportunity for 
noticing a remarkable and very distinct species originally 
described by Guenee, who supposed that it had been 
collected in Lapland. M. Ragonot has recently re- 
described it from a North American specimen in his own 
collection which I have had the opportunity of examining. 
The precise locality is still unknown. It is undoubtedly 
a Psedisca with normal neuration and a distinct brown 
costal fold, and therefore, inadvertently placed by 
Ragonot in the genus Conchylis, although vein 2 of the 
forewings may be said to come from the commencement 
of the outer third of the cell. Its position would appear
