cell. Palpus moderately long, with small, oval terminal joint. Vein 6 of the forewing arises near vein 5 
and appears to spring from the apex of the cell, as the upper discocellular vein is very long and forms 
a continuation of the anterior margin of the cell. Hindwing with small, distally curved precostal vein. 
The genus is represented both in West and South Africa and also in East Africa. 
The species may be divided into three groups. 
Synopsis of the Groups. 
I. Wings densely scaled, with orange-red ground-colour. Forewing above very broadly black at the apex, 
with white subapical band. Both wings beneath with white marginal spots. First Group. 
II. Forewing above without white subapical band. Wings beneath Avithout white marginal spots. 
x4. Wings not semitransparent, ground-colour red-yellow to whitish. Forewing nearly always with a round¬ 
ed, free black dot at the end of the cell or, if this dot is absent, beneath with large black mar¬ 
ginal dots. Second Group. 
B. Wings short and broad, semitransparent with white ground-colour, at the distal margin more or less 
blackish, but always without marginal, submarginal and discal dots. Forewing also always without 
free round dot on the transverse vein. Third Group. 
First Group. 
Only a single species, which approximates in colour and markings to Cooksomia and Telipna. 
P. hiendlmayeri Dew. (61 e). Both wings orange-red; apical half of the forewing as far as the hinder 
angle and the middle of the costal margin black with narrow white subapical band and beneath in addition 
with white marginal spots. Hindwing with black marginal band only 1.5 mm. in breadth, which is unspotted 
above, but has white spots beneath. Congo region: Mukenge and Ikelemba. 
Second Group. 
This group embraces the typical Pentila species, whose pattern consists of black or blackish spots, usually 
free but sometimes more or less confluent, on a light ground. These spots are most distinct and best separa¬ 
ted on the under surface and, when complete, consists of: 1. Basal dots in the cells and at the base of cel¬ 
lules lb, 2, 9 and 10 of the fore wing and 1 c, 2 and 7 of the hindwing; 2. A median dot at the end of 
the cell; 3. Discal dots in cellules 2—6 and 9 of the forewing and I b—7 of the hindwing; 4. Submarginal dots 
in cellules 1 b—6 and 8 of the forewing and 1 c—6 of the hindwing; 5. Marginal dots at the extremities of 
the veins. These dots are thus arranged almost exactly as in Pardopsis punctatissima (53 a). 
Synopsis of the Species. 
I. Wings above with red-yellow, orange-yellow or ochre-yellow ground-colour. 
A. Hindwing above with black or black-grey marginal band or at least with large, black, contiguous mar¬ 
ginal spots. 
a. Both wings beneath with rounded, free discal and submarginal dots or at least with the latter or 
instead with thick black streaks at the distal margin on the interneural folds. 
*. Wings beneath at the distal margin without black longitudinal streaks on the interneural folds. 
§. The black marginal band on the upper surface is very broad and covers also the discal dots, 
which are closely approximated to the submarginal spots. In cellule 2 of the forewing 
the discal dot is placed much nearer to the submarginal than to the basal dot. 
0. The black tip of the forewing above is very broad, reaches the apex of the cell and entirely 
or almost entirely covers the base of cellules 5 and 6. Ground-colour of the upper sur¬ 
face red-yellow. P. nero.
