CYRESTIS. By H. Fruhstoreer. 
On the under surface the f. w. are plain gray-white, whereas in coresia they have a purplish irridescence; 
The bands in the cell are brownish-violet, not pale blue as in coresia. The under surface is further distinguished 
by the larger brown spots in the anal region of the f. w. and a very distinct row of dark brown submar¬ 
ginal spots on the h. w. which are in the Javan form violet and but faintly indicated. Expanse, <$ 52—59 mm, 
Icannegieteri . $ 53 mm. Island of Nias, apparently very scarce. — kamiegieteri Fruhst. has on the f. w. not even a trace 
of a white oblicpie band. In the $$ the marginal area of the h. w. is light blue occasionally sprinkled wdth 
whitish near the black submarginal spots. When flying they resemble Euthalia ; it is not easy to obtain 
specimens that are not mutilated. Western Sumatra, from the foot-hills to the table-land of Battak (Mar- 
coresia . tin). — coresia Hbn. is among all forms most richly adorned with white. In the three rows of white dots 
are still more distinct than in rothschildi ; on the h. w. the anal border is broadly sprinkled with white, but 
not cpiite so much as in subucula, the black submarginal spots are more prominent than in the forms from 
Nias and Sumatra. In the $ the h. w. is pure white in the outer half which is proximally bordered by a 
light sky-blue band growing broader towards the anal angle. The under surface shows in both sexes a pure 
white conspicuous oblicpie band on the f.w., and on the h. w. a white terminal border which extends beyond 
the submarginal spots, coresia is always found together with Amnosia decora; like this it is confined to western 
Java, where I observed it only on the volcano Gede at elevations of from 4—5000 ft., in the forest-clad gorges 
whose cpiiet was only broken by the roar of the water rushing over the rocks. The butterflies sat with expand¬ 
ed wings on the clayey wet ground fully displaying their gorgeous azure-blue, feasting of the excrements 
of the Luak, and were so absorbed that I could stoop down and take them up with my fingers. All the spe¬ 
cies of Stibochiona, although not endowed with rapid flight, flutter wildly when in the net making it almost 
impossible to obtain any faultless specimens. 
schoenberg i. St. schoenbergi Honr. (= persephone Stgr. 1892) (115 e). larger than coresia-<$, f. w. black with 
a white subapical spot and the fringe checkered white and black. The $ has 011 the upper surface the 
distal half flesh-coloured, bordered with reddish ochre-yellow and enclosing pale blue-violet ocelli. Under 
surface chiefly brown like the upper surface; with three minute white dots below the costal spot; in the 
$ the marginal border is uniform pale fulvous, on the h. w. the six intranerval ocelli of the upper surface reappear, 
but are smaller and darker. Kina-Balu district; rare. Although so far Stibochiona has not been found in the 
Malay Peninsula, it seems highly probable that some form allied to S. nicea occurs there in the higher mountains. 
Tribus Marpesiidae. 
Genus: Clyrestis Bsd. (recte Marpesia Hbn.). 
The oldest name of this bicontinental genus is Marpesia Hbn. (1816), being based upon the same species 
(thyonneus Cr.) as the much younger but better known genus Cyrestis Bscl. (1832). Westwood was the first 
who in 1850 gave us an exact and scientific diagnosis of the genus, after Doubleday had in 1844 transferred 
the name Marpesia to a Neotropical species of the genus Megalura Blanch, established four years later. If 
I do not use here the name Marpesia , it is because it would conflict with Vol. I as well as with the head¬ 
lines on the plates of Vol. IX. which had been printed a year before I had established the priority. Hueb- 
ner wisely recognized the relationship of Cyrestis with the present genus Megalura uniting all species in question 
under the name of Marpesia', and indeed the two genera, although found in opposite parts of the globe, are so 
closely allied that one must assume that they belong together. In their chief characteristics they agree 
with Limenitis , but deviate from that group in the lack of the median spur and in that the fourth subcostal 
branch instead of the third runs to the apex of the wings; thus it was with some reserve, that Dr. Schatz placed 
them with that group. It was therefore a happy thought, when Aurivillius introduced the name Marpesiidi 
for the group in question, of which in Africa only the genus Azania Mart., in the Neotropica Region the genus 
Megalura Blanch, are known, whereas in southern Asia two sharply separated genera exist ( Marpesia and Cher- 
sonesia). 
The striking external aspect of Cyrestis alone would suffice to characterize it as a distinct genus. Its 
entire appearance, the more broad than elongate forewings, the hindwings which are broadly produced at the 
inner angle, the short tail at the third median nervule (by which Huebner characterized this genus, analogous 
to the longer tail of Megalura ) and the fine striated markings preclude the possibility of mistaking Cyrestis 
for any other Nymphalid genus. Moreover it is distinguished by the uncommonly long beak-shaped palpi, 
which are in front covered with short, closely appressed hair, whereas the middle joint is provided with a crest 
of stiff bristles; the upper joint which is larger in £ than in $ is almost % as long as the middle one. An-
