forest and had been rolling in the sand of the river; the enormous hole resulting therefrom l could only explain, 
when I noticed the dried-up droppings almost equal in size to a wagon-wheel that had been deposited on the 
sand by the frolicking animals. — The larva is purplish-black, with dorsal and lateral rows of branching, blue 
spines and a median row of white spots. The pupa is reddish-purple, with numerous black dots. Also Moore 
reports that the imago is rare, being found as a rule at elevations of from 2000—4000 ft., occasionally also 
on the roads leading through the forest-covered low-lands. - andamanensis Fruhst. (= andamanica Moore). 
The d is above of bright red-brown colour, the ? has, compared with the ? of ceylonica, much broader yellow 
bands, placed on the f. w. in horizontal direction. Both sexes are distinguished by the conspicuous white 
double spots on the f. w. Occurs in the Andaman Islands, according to Moore also in the Nicobars. — mariae 
Fruhst. (113 a) is the first of the series of Macromalayan forms. The d is smaller than ceylonica-d, having 
the f. w. dark tan-coloured, with short, broad, subapical bands, sligthly irrorated with reddish The ? resembles 
the figure, always with a black discal spot which is distaily never united with the black apical border. The 
under surface of the dd invariably follows the f. argyroides. Of the ¥¥ specimens only one resembles a dried 
leaf, whereas live others have both wings spotted with white at the base. The larva is always found on 
Graptophyllum hortense, an ornamental shrub much used by the Malays for the decoration of their graves; 
generally one finds several dozens together. It is black with steel-blue head; each segment carries eight long 
steel-blue spines, which do not branch, but are covered with short bristles. Dorsally and laterally it is striped 
with white. Above each leg is a brick-red spot. The pupa is light brown with dark brown spots; it takes from 
8—10 days to develop the imago. Martin relates that the ?? are often found resting on the woodwork of old 
bridges in the woods and even alight upon ox-carts; the larva lives also on Artocarpus integrifolia, the Jack- 
fruit-tree. Valve with nearly circular median disc, ventrally provided with a projecting, distaily somewhat 
curved ledge. Uncus long, stout, in-curved at the end. Penis long, membranous, basally ending in a fine tube, 
niasica Btlr. somewhat inferior in size to mariae; the dd are, in consequence of their insular character, rather 
darker; the same may be said of the deeper brown-green upper surface of the h. w. of the ??. The yellow- 
brown spot on the f. w. of the dd is still shorter than in mariae ; in the ? the median portion of the f. w. 
is of a paler yellow colour; the under surface is remarkably light yellow, the ocelli are pupilled with fulvous 
Also in the d the subapical portions are irrorated with yellowish. From the island of Nias, also from Engano 
and Mentawej: in the latter two islands very scarce. — surculus subsp. nov. (112 c), a dwarfed form, distinguished 
beneath by the presence in the dd of a whitish, rather broap, anal border on the h. w., occurring also in 
the ¥¥, although not so distinct. All the dd specimens taken between July and September belong to the f. 
argyroides. From the island of Bawean; not rare. — pratipa FI dr. inhabits the Malay Peninsula. In the d. 
the wings are strongly curved, with far-projecting, not rounded apex and with a long, thin, anal tail on the 
h. w.; its colour is a deeper red-brown than is seen in mariae dd from western Sumatra. The ¥ occasionally 
corresponds to the ? of mariae, although some specimens are rather smaller in size, with a broad black band 
crossing the f. w. Not very abundant. — borneensis Fruhst. (= borneensis Moore 1900) is the darkest among 
the Macromalayan insular forms and very constant. It is easily distinguished from pratipa by the roundish 
contour of the f. w. and the unusually broad, black, apical border. The ' d is also remarkable for an 
intraradial yellowish spot, located, as in philippensis, beyond the transverse band on the f. w. The ? is 
in the median region somewhat lighter-coloured. In the d the colour of the under surface is rather uniform; 
the ?? which follow the type of argyroides , are dark tan-coloured. North and South-Borneo. —- bisaltide Cr. 
is, in contradistinction to the preceding form, exceedingly variable, occurring in Java in two forms which, 
although not influenced by the locality, vary to such an extent that they have always been treated as tw r o 
distinct species. The dd with silvery spots on the under surface seem to be in the majority; this spotting is 
most strongly developed in the larger specimens from eastern Java. Above they may either resemble thecfcT 
of surculus (112 c) or be marked, analogous to celebensis, with a wreath of white dots (coronata form. nov). All 
the dd specimens from eastern Java contained in my coll, have the median area of the f. w. red-brown 
throughout, whereas in some others from western Java it is anteriorly yellowish in colour (exornans form. nov). 
1 have dd with leaf-like under surface from western Java, which show the wreath of white dots, whereas 
those from eastern Java do not possess it. The large-sized ¥¥ from those localities most probably belong to 
the monsoon period; they always display the white dots. This ? form I name polibetina form. nov. because it 
had previously been classed with the Amboina-form polibete and forms the greatest imaginable contrast with 
the ¥-f. bisaltide Cr., which is most likely peculiar to the dry-season; this view is supported by the presence 
of the pale yellow, median zone which reminds us of mariae Fruhst. from Sumatra, and the equally light yellow, 
transverse band on the f. w., both of which are on the under surface accompanied by light yellow or red-brown 
markings. From eastern Java 1 possess also three dd, belonging to the fa. basalis a id resembling above the 
dark, white-dotted cf-form. The imago is found throughout Java up to 2500 ft. of alt,., generally at the edge 
of the woods, in plantations and fruit-orchards. The larva I repeatedly encountered in the hotel gardens at 
Malang in eastern Java; according to Dr. Piepers it feeds on Acanthaceae and Euphorbiaceae; it is most gaudily 
coloured, resembling that of philippensis, but according to Semper greatly differing from that of ceylonica Fruhst. It. 
is black, with five white longitud. stripes; above the prolegs are found red wartshaped projections, connected with 
one another by double white lines. The dd I took in Lombok follow the type argyroides and are, analogous to sur¬ 
culus, without the frontal wreath, but with a yellowish intraradial patch on the f. w. The ¥ is very large, not quite 
so pale yellow as bisaltide 6V.-¥, otherwise quite identical with it. Four dd have the under surface red, five ¥¥
