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. 

 Ejrp. al., 20 mm. IL'iidtctnys pale fawn-grey ; cilia whitish. 

 Abdomen and Leys 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 Conchy Us, 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
