the inner, these lines are but feebly developped in typical specimens from Treasury Island, but reach their 
highest development in those from Ysabel and New Georgia. On the upper surface of the h. w. the two middle 
ocelli often show a tendency to run together in consequence of the yellow border having disappeared. —

the median band broadest at the costa of the f. w., whence it gradually tapers to a rather sharp 
point at the anal angle of the h. w. Whereas in both types the median band is strongly laved with yellow, this 
colour is only just indicated in the specimens contained in the Tring Museum; thus it appears that also in this 
species yellowish and white specimens exist, just as we have seen in thyodamas, lutea and the subspecies of strigata. 
The ocellate chains are complete having on the h. w. an uncommonly broad yellow border distally nearly twice 
as broad as proximally. On the h. w. the pale line flanking the inner edge of the row of ocelli stops precisely 
at the 4. ocellus counted from the anal angle, whereas in nitida it reaches the 5. or 6. ocellus. The anal ocellus 
is round, reversed ocellus distinct. In his original description Mathews does not lay sufficient stress upon 
the nature of the median band, and all the specimens passing in Germany under the name of salomonis surely 
belong to nitida. The island of Ugi, on which the type of salomonis was found, belongs to the very large island 
of San Christobal at the eastern extremity of the entire Archipelago, on which undoubtedly also salomonis 
occurs. A prolonged stay on the island of San Christobal seems to be, just as in Bougainville and Choiseul, 
next to impossible on account of the hostile character of the natives (Martin). — ulawarsa Mart., from the ulawana. 
island of Ulawa in the Solomon Archipelago, described from 2 (Woodford) in the British Museum. It occu¬ 
pies a position cpiite by itself, by virtue of its narrow white median band beginning in a sharp point below 
the subcostal vein on the f. w. and ending in the same manner at the anal angle of the h. w.; at the point 
of its greatest width it is not any broader than in strigata. Anal ocellus round, reversed ocellus distinct. Ground¬ 
colour lighter than in nitida. The ocelli in the middle of the chain on the h. w. have on the upper surface the ten¬ 
dency to flow together. 
C. eximia Oberth. from the Sangir Islands, is a good name for this extraordinary and completely isolated eximia. 
species or form. The white median band is not parallel to the body or the outer margin of the wings, but turns 
on the f. w. from the brown-bordered costa obliquely toward the outer margin; at the point of intersection 
with the second median it turns in the direction of the inner margin as far as the third median, whence it con¬ 
tinues in the shape of a yellow undulate line that reaches the margin. On the under surface the band is more 
fully developped continuing distinctly white, though very narrow, to the inner margin. At the apex of the 
f. w. is placed a striking white spot. The h. w. is, aside from a little whitish spot in the middle of the costa, 
entirely brown. Whereas on the h. w. the row of ocelli is complete, on the f. w. only the three anal ocelli are de¬ 
velopped, those nearer the costa being quite indistinct. — dola Fruhst. from Fergusson, deviates from acilia iota. 
in the darker ground-colour, the white cliscal band which tapers towards costa and anal angle and the more 
rounded short-tailed wings. On both wings the black-brown basal region is much broader and distally 
more sharply defined. The colouring of the h. w. is not so faded as in acilia; on the under surface all the 
brown bands are more straight, much broader and darker brown and have on both wings the chain-pattern 
much larger, more uniform and complete. — tervisia subsp. nov. is a somewhat darker form from the main tervisia. 
island of New Guinea, distinguished from the form from Waigeu in having on the upper surface the white 
median band distinctly narrower, and on the h.w. the yellow anal area much wider, encroaching upon the white 
median area. Type from Dutch New Guinea, Sorong. from the German and British parts of the island 
have the longitudinal stripes on the upper surface not so close together. •— bassara Fruhst. lately discovered bassara. 
in Matty Island to the north of Berlinhafen, is a small delicate form intermediate between acilia, tervisia and 
ribbei Mart, from Neu Mecklenburg; it has the markings and bands of ribbei, whereas in its dull brown-gray 
colouring it approaches tervisia. Fruhst. 
Genus: C'hersoiBcsia Dist. 
All Chersonesia have a rich yellow or orange ground-colour, darkest in the eastern species; the markings 
are black, consisting in the three well-known meridional stripes of which the basal and middle one are always 
double, whereas the third one, which is nearest the margin, is generally single (only two species having it double), 
not clearly defined and often widening out to a band; the other markings are a submarginal band formed 
of three components and adorned on the h. w. either by a blue ornamental line or in the majority of cases with 
a distinct ocellate chain, and finally a delicate marginal line. Both the anal projection and the tail at the apex 
of the third median are always present, although in a few species greatly reduced or cpiite rudimentary. The anal 
ocellus is double, representing two links in the row of ocelli. The f. w. has in the western species the apex di¬ 
stinctly falcate, whereas the anal angle of the f. w. and the apex of the h.w. are shortened in the same manner as in 
Cyrestis. Chersonnesia inhabits the southern part of the continent of Asia ranging along the southern slope of the
