neo, being found in the woods of the plains both in the north and south. The $ can be easily distinguished 
from the Javanese name-type by the greater extent of the yellow colouring on the inner angle of the hind- 
wings, and the much reduced ocelli. — A form has been described as depupillata Fruhst. in which the apical depupillalu. 
ocelli on the hindwing are entirely wanting. 
13. Genus: Tlutlirisi Moore (= Morphindra Rob.) 
The sole species of this remarkable genus was formerly united with TJiaumantis, until Moore separated 
it in 1895. The subcostal Avith five branches as in TJiaumantis, but all free to the apex. Abdomen characterized 
by its compressed form, and the lateral hair tufts an the apical segments, reminding of Amathusia ; $ with large, 
coarse, androconial patch' before and in the cell, which it almost fills, and two brush-like tufts, one before 
the subcostal, the larger in the apical part of the cell. The hairs of both tufts are curved backwards so as 
almost to cover the scent scales. There is another smaller tuft on the bare membrane on the internal nervure 
upon the anal lobe of the wing which enfolds the abdomen. Among the forms of the only known species, one race 
includes the largest butterflies of the inclian region. Habitat; all Further India, and the northern half of the 
macromalayan region. 
T. 
ty, aliris of which four local races are known, has ahvays a white band on the forewings, varying in 
breadth, and large golden-velloAV distal spots on the black-brown ground of the hindwing. Underside of the 
hindwing with two handsome variegated eye-spots, somewhat resembling the ocelli of the larger Brassolidae. 
Antennae still lighter red-brown than in Thaumantis. — lathyi Fruhst. (102 b $ instead of $) the most latliyi. 
eastern representative of the species, had not been reported from Tonkin previous to my travels in East Asia. 
It is smaller and darker in colour than its nearest connection, intermedia from Burma, the apical spots on the 
forewing are bluish instead of white, and the transverse band of the fore wings is narrower. On the hindwings 
the ochre-yellow suffusion on the apical and anal portions is reduced, Avhile the black-brown basal region is 
further extended. The brown median band on the underside of the hindwings is deeply indented, whereas 
in intermedia it is almost straight. All ocelli are larger, and the anterior eye-spot is bounded internally by a 
more yellowish band. $ decidedly larger than the rf, the blue bands and spots on all Avings more extended. 
lathyi stands close to the boundary of specific rank, for the long hairtufts in the cell on the upper surface 
of the hindwing are Avanting, although peculiar to the other subspecies of aliris. I first had the pleasure of 
taking lathyi in the ravines among the limestone hills of the Than-Moi range in North Tonkin in June, and later, in 
September at the military post of Cao-Kien near Chiem-Hoa, in Central Tonkin, on gneiss, at about 300 m, but 
ahvays in the densest AVoods and only shortly before sunset, Avhen the creatures appeared ghostlike out of the 
Ioav thickets, and fluttered around for a moment, timid and awkward, rather after the fashion of Melanitis. 
In company with them were the Satyrids Erites pseudofalcata (p. 303) Ragadia crisilda (p. 360, PI. 90 e), Pharia 
thalia Leech (Vol. I, p. 295, PL 29 a), Coelites sylvarum (p. 329, PI. 94 b). If one pursues Thauria lathyi , it hides 
in the thicket with folded wings, and, in consequence of the indeterminate colouring of the underside, it is 
very difficult to find, intermedia Crow, first discovered in Lower Burma by Colonel Bingham; the species Avas intermedia. 
on the wing in October and again in April in the Donat ranges, later it Avas found by Doherty in the Karen 
Hills in March and April, so that it is almost certain this species is double brooded; it is rare in Lower Tenasserim. 
As compared with lathyi one notices especially the fiery red-brown of the more extended anal suffusion on the 
upper side of the $, the lighter grey basal portion of the underside of the hindwings, and the more sharply 
defined, milky white instead of yellow-white oblique band on the underside of the forewings. — In pseudaliris pseudaliris. 
Btlr. the darkening has gone further, and, according to Distant’s figure, the yellowish white band on the fore- 
Avings is reduced to a narroAV point in the anal angle. The $ is yet undescribed, and the is rare. It occurs 
from Malacca and Perak on the Malay Peninsula, and the Siamese island of SalangR, north of the Straits of Malacca. 
— aliris Westiv. the most splendid form, apparently not uncommon on south-east Borneo. Waterstradt aliris. 
also discovered it later in the alluvial lands of Brunei in North Borneo, whence I have 2 3U and a gigan¬ 
tic ad remarkable for a transverse band on the fore wing, of thumb-breadth, edged Avith light bluish Avhite, 
distally and proximally deeply indented. The brown-black median part of the hindwing is more uniform in 
breadth than in the continental representatives, and on the underside of the hindwing the anterior ocellus is 
more fully developed than the posterior. The median area on the underside of the hindwings is dark brown, 
in place of yelloAV-broAVn.
