spot. Expanse of wings: $ 58 mm; unknown. Ecuador. 
P. brumalis Schs. (166 b). Dark greyish brown, a white line along the median vein from the base bends brumalis. 
upwards at the cell-end, extends to the costal margin and bifurcates in the upper half; from the apex a white 
submarginal line extends at first along the margin, then to the middle of the inner margin; the costal-marginal 
area is darker mouse-coloured, the distal area greyish brown; the median line is edged with reddish bronze. 
Expanse of wings: A 23—35, $ 35—43 mm. Brazil. 
P. chica Jones differs from brumalis merely in its very light yellowish ochreous colouring and may be chica. 
only a differently coloured form of brumalis. Expanse of wings: <$ 25—30 mm; $ unknown. Paraguay, Brazil. 
P. cicur Schs. (166 b) is still lighter than chica, the white lines and the more variegated ground-colour cicur. 
quite indistinct, the reddish ochreous ground exhibits only the brown borders of the light lines. Expanse of 
wings: A 30 mm; $ unknown. Brazil (Rio de Janeiro). 
P. burchelli Dyar. The white line along the median vein bends up to the apex and is not forked, the burchelli. 
costal area is red-brown, the inner-marginal area excepting the base blackish grey. Expanse of wings: 31 mm; 
$ unknown. Brazil (Goyaz; Lassance, Minas Geraes, im November 1919, Coll. Cornell University). 
P. prosper Dyar (166 b). Forewing white, suffused with olive brown, leaving free a broad white sub- prosper. 
marginal band with irregular margins; strewn with white around the cell and at the margin; a dark dot in the
