" Larva cylindrical, spiny ; the spines on all the segments about equal in length. Pupa 

 elongate ovate, constricted, spiny." (Doubleday, I.e.) 



Aiella is a genus of rather small extent, occurring in Africa, throughout India and thence 

 through the Malay archipelago. Two of the Indian species occur in the hills up to 7,000 feet, 

 and are to be met with also in the lower valleys and the plains. A. phalanla (the only species 

 I have seen on the wing) loves the sun, is very active in flight, but settles frequently on 

 flowers. 



Zey to the Indian species of Atella. 



A. Hindwing witll a distinct tail at the end of the third median nervule.

serim, Malay Peninsula, Sumatra. 



B. Hindwing with its outer margin rounded ; no tail. 



a. The cell of the forewing crossed by two irregular black bars besides the two which 

 enclose the disco-cellular nervules. 



314. A. PH4LANTA, India, Malayana, China. 



h. The cell of the forewing crossed by four black lines in addition to the two which enclose 

 the disco-cellular nervules. 



315. A. ALCIPPE, Sikkim, Sylhet, Mergui, Malay peninsula, Andaman and 



Nicobar Isles. 



The first species, A. j/«^^,appears to be at least subgenerically separable from the typical 

 species A. phalanta, not only on account of the very different shape of the hindwing, but 

 also in the shape of thg discoidal cells in both wings, these being in A. sinha much more 

 obtuse at the apex, and in the hindwing ending distinctly short of the origin of the second 

 median nervule, while in A. phalanta the apex is slightly beyond it. The style of marking 

 too is very different, ^. />/ia/(Z«/(i closely resembling an Argynnis ox 3. Melidca on the upper- 

 side, while A. sinha more nearly resembles a Cynthia.

Description : " Male. Upperside, forewing ochraceous ; a dark waved fascia commenc- 

 ing at costa beyond end of cell, concavely extending to third median nervule, and then 

 obliquely deflexed beneath cell to near inner margin ; within the fascia the colour is 

 brownish, the cell being crossed by four narrow black fasciae ; the apex more or less suffused 

 with blackish, either totally and enclosing some ochraceous spots, or exhibiting two modera- 

 tely well-defined oblique fascise ; outer margin broadly blackish, preceded by a narrow 

 submarginal line of the same colour, and with four small blackish spots, of which three — 

 always visible — are placed two above and one beneath the second median nervule, and the 

 fourth — sometimes fused in the apical colouration — situated between the discoidal nervules. 

 Hindwing of the same hue as the forewing, but with the outer third brownish, inwardly 

 marked by a series of small dark spots placed between the nervules, and with broad 

 marginal and submarginal dark fasciae, between which the colour is narrowly pale ochraceous. 

 UtiDKKSiDE., forewing w\i\i the basal dark colouration more violaceous, the cell pale, but dark 

 between the narrow black fascice, all the dark markings much paler, being browni-^h or 

 violaceous, and with a series of distinct pale lunulate spots crossing the wing before the dark 

 spots. HinJu)ing more or less violaceous, crossed by two medial and much-waved narrow and 

 darker fasciae, between the upper portions of which the colour is pale ochraceous, and both of 

 which are more or less outwardly margined with pearly greyish ; a greyish subquadrate spot 

 in cell margined on three of its sides with dark violaceous, the outer discal spots margined 

 with rufous, but with the one above the third median nervule obsolete j outer margins pale,
