ATELLA. By Dr. C. Attrivillitts. 
at vein 4. Vein 11 of the forewing from the apex of the cell; veins 3 and 4 short-stalked-or from the same 
point. Sexes differently marked above and the <$ with a large pilose spot before the apex of the hindwing. 
In the $ the wings have on the upperside a distinct dark dentate median line, which separates the darker 
basal half from the lighter distal half; in the A this median line is entirely absent or is only developed 
between the costal margin and vein 4 of the forewing and the basal part is not darker than the distal. In the dis¬ 
tal part of the hindwing there is in both sexes a transverse row of rounded black discal spots and before the 
distal margin three dentate or strongly undulate black lines, of which the proximal one in the is often in¬ 
distinct and the distal occasionally joined to the dark distal margin itself, and on the forewing three such 
transverse lines, of which in the the proximal is broken up into free spots or dots and the distal almost 
fused with the distal margin. On the under surface these markings are light brown to yellow-brown (only 
in cellules 1 a and 1 b of the forewing blackish) and the discal spots of the hindwing developed into eye-spots; 
the median line is here distinct in both sexes and on the hindwing distally accompanied by white or sil¬ 
very spots. The early stages are unknown. 
iole. L. sole F. (52 f). A'- both wings above uniform orange-yellow; the forewing without black markings 
at the costal margin between the base and the submarginal dots; the under surface with dull, ochre-yellow 
ground-colour. wings above in the basal half dull yellow-brown, in the distal half light yellowish, beneaths 
hecataea. lighter than in the <$. Sierra Leone to the Congo and Ruwenzori. $-ab. hecataea Hew. differs from the type- 
form in having the ground-colour of the wings above blackish in the basal half and white in the distal. — ab. 
afzclii. afzelii Auriv. has t he ground-colour beneath darker, inclining to violet, and at least in the distal half of the hind¬ 
wing with mother-of-pearl gloss. Sierra Leone. 
ayresi. L. ayresi Trim, is possibly only the southern and eastern race of iole. The hindwing is distinctly angled 
at the extremity of vein 4 and the pilose spot of the <$ is smaller than in iole. In the the fore wing has 
above a black dot at the anterior margin of the cell and shortly behind the cell a thick, obliquely placed black 
transverse streak from the middle of the costal margin to vein 4 and midway between this transverse streak 
and the submarginal dots is placed another black costal spot, which, however, only reaches vein 6; the proxi¬ 
mal black marginal line of the forewing shows a distinct tendency to thickening at veins 4 and 5, occasionally 
forming a large black spot. The $ is unknown to me; according to Trimen’s description it scarcely differs 
above from the $ of the type-form, but is said to be very light grey-yellow beneath, with bronze-green 
dbbotti. reflection. Natal to British East Africa. — $-ab. abbotti Hall, has a violet gloss on the under surface. German 
East Africa. 
3. Genus: Atella DU. 
Atella nearly approaches the preceding genus, only differing in the characters given in the synopsi 
and in the rounded hindwing. 
The species are nearly allied and all have the ground-colour above orange-yellow or brown-yellow, 
with the following black markings: a fine line, usually thickened at the extremities of the veins, at the distal 
margin itself; two lines before the distal margin, the outer one on the forewing sometimes fused with the distal 
margin; a row of rounded submarginal dots, five (in 1 b—5) on the forewing and four (in 2, 3, 5 and 6) on 
the hindwing; a median line composed of streaks or lunules, but usually only present in cellules 4—6 and 8 of 
the forewing; 5 or 6 discal dots on the forewing, placed at the base of cellules 1 b—6 and finally two trans¬ 
verse streaks at the end and two in the middle of the cell on the forewing. On the under surface these markings 
are more indistinct and for the most part brown or yellowish; the median line is completely developed and the 
submarginal dots changed into eye-spots. The larva is armed with spines; the head, however, without spines. 
Pupa nearly straight with obtusely rounded head and two conical protuberances on each segment of the tho¬ 
rax and the abdomen. 
The genus is also widely distributed in the Indo-Australian Region. Cf. vol. I, p. 243, pi. 71 d and vol. 
IX, p. 470. 
cohimbina. A. colutnbma Cr. (52f). Distal margin of the hindwing distinctly angled at vein 4; the black markings 
of the upper surface more strongly developed than in phalantha; the marginal line on the upperside of the 
forewing continuous; the proximal submarginal line of the forewing usually forms in 4 a long, sharp angle 
proximad, which nearly reaches the submarginal dot; the submarginal dots on the underside of the hindwing 
large and black with brown rings; the discal spots of the forewing beneath scarcely noticeable. Sierra Leone 
ynicrops. to Natal, British East Africa and Uganda. ■— - microps Rothsch. & Jord. only differs in having the base of the 
wings above darkened, olive-brown. Somaliland and Abyssinia. 
philiberti. A. philibertl Joannis closely approaches the preceding species and, like it, has the hindwing distinctly 
angled at vein 4. From the other species it differs in having the median line of the upper surface completely 
developed; this is broken up into spots on the forewing, but on the hindwing it is continuous and borders the 
darker, olivaceous basal half; on the forewing only the basal third is darkened. Seychelles. 
A. phalantha Drury. The type-form only occurs in Asia (vol. I, p. 243, 471). — aethiopica Rothsch. &
