Al. ant. long., o’', 28 mm. Al. ant. lat.. «1, 11 mm. Marg. ext., o, 
14 mm. 
Habitat. — Fort Crampel, French Congo. One male in coll. B. Preston 
Clark, received from Messrs. Luck and Gehlen. 
In form nearest to P. retusus, but a complete contrast in point of color. 
Palpi pink beneath, brown along the eyes. Antennae light brown. Head, 
thorax and abdomen above light pink, unicolorous. Beneath, dull pink, 
irrorated with brown scales. 
Fore wing above light pink, shaded with deeper pink. Three trans- 
verse lines cross the wing from costal to inner margin. The inner, a me- 
dian line, runs in a wavy S from a point midway of the costal margin to a 
point 8 mm. distant from the hinder angle. The second, a postmedian line, 
runs parallel to the median, 5 mm. distant. The area between these two 
lines makes a darker pink band. The third, an undulate submarginal line, 
runs from a point 3 mm. distant from the hinder angle obliquely to SC5, 
being at that point 6 mm. distant from the distal margin; thence it is 
angled sharply basad to the costal margin. This line is of slightly deeper 
tint on the veins. A large pink stigma on the cell, with light centre. An 
undulate subbasal line runs transversely from a point distant 5 mm. from 
the base of the costal margin, becoming faint toward the inner margin. A 
line of faint vein dots midway between the submarginal line and the distal 
margin, terminating in a subapical spot 5 mm. from the apex. Cilia brown. 
Hind wing light pink, darker toward anal angle. Dark pink elongate 
patch on SM2, midway of abdominal margin, 5 mm. in length. Subanal 
dot dark pink. Cilia pink, except at anal angle where they are brown. 
Both wings beneath pink, light at base of inner margin of fore wing, and 
at anal margin of hind wing. Fore wing crossed by three faint undulate 
lines, the inner duplicating the line of the first postdiscal line above, the 
outer duplicating that of the line of submarginal dots above, and the middle 
one that of the posterior postdiscal line, save that it curves evenly, and is 
not sharply angled at SM5. Cilia dark. Hind wing crossed by three faint 
lines: The inner one, median, obscure; the middle one, postmedian, runs 
from the anal angle at first straight, and then curving basad, to the costal 
margin; the outer one from a point just proximal of the anal angle in a 
direction parallel to the distal margin, but drawing gradually away from 
it basad, to the inner margin. Cilia dark with light tips, except entirely 
dark at anal angle.
