is more oblique ; the costal fold is also decidedly darker 

 than in that species. 



Padisca albiguttana, Zell. 

 N. Carolina. 



Pcedisca mornsoni, n. s, (PI. IV., fig. 8). 

 Palpi white, the short apical joint quite concealed in the closely- 

 packed projecting scales of the 2nd joint. Head white, thickly 

 clothed with raised and projecting scales above and in front. 

 Antennae white. Thorax white, a pale fawn-coloured line dividing 

 it along the middle. Patagia fawn-coloured. Fore wuigs (with 

 the costa slightly arched, the apex acute, apical margin oblique 

 and slightly concave) pale fawn-colour, with waved longitudinal 

 streaks of silvery white, without dark margms, which may be 

 divided into costal, median, and submedian. The costal streak runs 

 narrowly along the costal margin nearly to the middle, whence it 

 is deflected and dilated, assuming the form of more or less con- 

 fluent short costal dashes, the first three tending obliquely outwards, 

 the last two meeting them in the opposite direction before the apex. 

 The median streak extends from the base of the wing to the end of 

 the cell dilated outwardly for the first half of its length, where it is 

 suddenly contracted, on its upper edge, by an angulated break, 

 thence tapering to a sharp point which almost reaches a short 

 detached waved longitudinal streak which lies between it and the 

 lower half of the apical margin, and is itself somewhat connected 

 by detached spots at each of its ends with the middle and end of 

 the waved submedian streak. This submedian streak arises below 

 the fold, not reaching the base, and is deflected to the dorsal mar- 

 gin before the middle following it thence nearly to the anal angle. 

 A detached white spot lies near the base of the dorsal margin. 

 Along the upper edge of the outer half of the median streak, and 

 continued more conspiciiously between the confluent costal dashes 

 and the waved detached ultra-median streak nearly to the apical 

 margin, is a curious wedge-shaped dash of pale fawn-coloured scales, 

 each distinctly barred transversely with deep black. A line of 

 similar scales runs along the apical margin at the base of the cilia, 

 and is faintly reduplicated in the cilia themselves below the apex. 

 Hind wings rather shining fawn-grey. CiUa slightly paler. Expanse, 

 20 mm. 



One female. Montana. 



There is a worn specimen of this species in Mr.Grote's 

 collection at the British Museum, placed under the name 

 Gra'pliolitha striatana, Clem., together with others which 

 are correctly referred to that species.
