not appear to have been reached by this butterfly. — sthenelus Me. L. (= pictus Fruhst.). The cell of the forewing sthenelus. 
above with a large constricted transverse patch, which is as broad posteriorly as anteriorly. The posterior discal 
spots of the forewing and the band of the hindwing broader than in sthenelinus. The young larva black, without 
saddle-spot; the later stages lighter; the full-grown larva green, with rows of orange dots and above the legs 
a white longitudinal stripe, the abdominal legs whitish. On Citrus and other plants. The butterfly in open 
country, especially in lucerne and clover fields; North-West Australia, Queensland, southwards to Sydney; 
the specimens from the islands in the Torres Straits probably belong here. This form is also common on Sumba 
Island, to the south of Flores; specimens from there cannot be distinguished from Australian ones. Fruh- 
STOREER gave them a name, erroneously comparing them with sthenelinus instead of sthenelus. The Sumba Lepi- 
doptera are usually very specialised; it may therefore be assumed that sthenelus has only recently immigrated . 
there. — novoguineensis Rothsch. Very similar to the preceding form; the cell-patch of the forewing more deeply neensD 
incised, the posterior discal spots smaller, the penultimate more deeply incised distally and anteriorly very dis¬ 
tinctly sinuous; the black markings on the underside of the hindwing larger and the basal area shaded with 
yellow at the black transverse band. Mathew found egg and larva on Salvia, both similar to those of sthenelus, 
the nuchal fork of the larva salmon-coloured. The butterfly on bare slopes on the south coast of British New 
Guinea: Port Moresby, Redscar Bay, lower course of the Aroa River. 
P. euchenor. Body beneath pale yellow. forewing above with a large spot at the apex of 
the cell, to wTiich is joined a discal band consisting of 5 large spots, often a few small spots distally to 
the end of the cell, a subapical band of at least three small spots; hindwing with very large central 
area which extends from the costal almost to the hindmargin, is cut off straight basally and irregularly 
rounded off distally and incised at the veins; all these markings pale yellow. Under surface as upper, 
but the subapical band of the forewing consisting of more spots, the central area of the hindwing extended 
to the base, and distally to it a row of submarginal lunules, of which the posterior ones and mostly 
also the costal one are ochreous yellow. In the $ the markings are paler and the discal spots of the forewing 
are reduced, the last but one commonly entirely absent. The larva, which was found by Wahnes on Citrus, 
rests on the upperside of a leaf; similar to that of P. gigon-, green, with broad black lateral stripe above the legs 
from the prothorax to the 1. or 2. proleg, a broad belt on the 3. and 4. segment, which is broadly united with 
the lateral stripe, from the middle of the body onwards the brown lateral stripe replaced by an almost white one, 
from which three other brown, oblique belts project upwards; on the pronotum two long, feebly clubbed 
processes, resembling the horns of a slug, in each of the three abdominal belts a couple of long pointed processes. 
The pupa green, head and breast very strongly curved upwards, the thoracic horn very short. The genitalia 
of the butterfly recall those of P. demolion. The butterfly is found in light, sunny woods, especially at water¬ 
courses, and has a swift and agile flight. A true Papuan species, whose area of distribution embraces the Key 
and Aru Islands, the whole of New Guinea together with the small neighbouring islands, and the Bismarck 
Archipelago. From Australia, the Solomon Islands and the Moluccas the butterfly is not known. It is true 
Pag-enstecher reports it from the North Moluccas, but the collection of Lepidoptera in question was bought there 
and the locality is therefore not authentic. — naucles Rothsch., from the Key Islands. <J: the cell-spot of the nancies. 
forewing above reaches to the base of the 1. median or still further basad, there is no black spot before the base 
of that vein. $: the 1. and 2. discal spots of the forewing are not separated, as the vein placed between them is not 
black, the 3. discal spot widely separated from the 2., -the 4. scarcely indicated, the 3, (placed at the hindmargin) 
elongate-triangular; the 1. and 2. projections of the central area of the hindwing above only feebly constricted. — 
obsolescens Rothsch. the cell-spot of the forewing above does not reach the point of origin of the 1. median, obsolescens. 
the 2. and 3. discal spots strongly rounded off basally. $: as naucles, the cell-spot of the forewing posteriorly 
somewhat shorter, the 1. and 2. discal spots separated by a usually very distinct vein-streak; the two anterior 
projections of the central area of the hind wing above more or less strongly constricted, commonly so strongly 
that two spots are separated from the central area; the penultimate discal spot of the forewing not indicated 
either beneath or above. Aru Islands. Not rare, principally in half-dry brooks. —- misolensis Rothsch. Small, misolensis. 
the blue spots wanting on the underside of the hindwing, only the last spot is always (?) indicated by a few blue 
scales. Misol, 4 GG in the Tring Museum, taken by H. Kuhn in January 1898. — euchenor Guer. (= axion Bdv., euclienor. 
lasos Fruhst., scribonius Fruhst., hippotas Fruhst.) (26 a). the subapical spots of the forewing smaller on 
both sides than in naucles and obsolescens, the 2. disca 1 spot not rounded off basalty; the submarginal spots of 
the forewing beneath small or not present, the hindwing always with blue spots. the 3. discal spot of the 
forewing above a -ways placed near to the 2., mostly touching it, the 4. spot always present, the interspace be¬ 
tween the 4. and 5. spots not broader than the latter; the yellow submarginal spots of the hindwing beneath 
very variable, the posterior ones commonly united into rings with the marginal spots, which is also sometimes 
the case in the $. The subapical spots of the forewing in both sexes from German and British New Guinea mostly 
larger than in the specimens from the Arfak Peninsula, but also sometimes smaller. In specimens from 
Waigeu the marginal spots of the hindwing are rather small and the inner margin of the pale yellow area of the 
hindwing above usually crosses the cell at the point of origin of the 2. median, which, however, often occurs
