BYTHARIA. By L. B. Prout. 
glareosa. wings thickened and much darkened. glareosa Warr., from New Guinea, described as a separate species, 
may be a race, but I can find no definite difference and shall not be surprised if it has to be treated as a 
fuscisecta. synonym. Median shade (or line) on the whole slenderer, underside possibly rather cleaner. — ab. fuscisecta 
Warr., taken at Biagi with the holotype of glareosa, is almost exactly like ab. mediusta only with the deep- 
brown median line a little less thick, and even this distinction does not hold for a fuscisecta from the Upper 
Aroa River. 
porphyropis. A. porphyropis Meyr. Intermediate in colour between the yellower and the more cinnamon species 
of the group — nondescript light-brown with grey irroration. Palpus extremely long, perhaps even more so, 
at least in the $, than in denticulata, but very similar. The ordinary lines generally weak; cell-ring of hindwing 
moderate, blackish, commonly surrounded with cinnamon-buff suffusion, its centre whitish or slightly purple. 
Meyrick chose as his type (probably because the most strongly-marked known to him, but unfortunately 
by no means the commonest) the form with some blackish subterminal spots and with a subquadrate blackish 
patch at the tornus of the hindwing (compare palirrhoea (19 d) or — as with the corresponding ab. maculata 
of flavirubra — a cluster of spots. Not rare in parts of New South Wales (the originals from Sydney — holo- 
simplex. type — and Newcastle) and of Queensland at least as far northward as the Cairns district. — ab. simplex nov. 
(19 g), described by Meyrick as “var. a” and characterized as having “all blackish dots changed to fuscous, 
indistinct; all blackish spots absent", is the commonest form. Type from Newcastle; we figure a $ from 
mediusta. Illawarra. — ab. mediusta nov., 2 $$ from Kuranda (ex coll. OberthItr), collected with the two preceding 
forms, is almost exactly like denticulata ab. mediusta except in the somewhat less yellow ground-colour. - 
meniscata. meniscata subsp. (? sp.) nov. Slightly broader-winged and more warmly coloured, in both these respects some¬ 
what intermediate towards flavirubra , but without the noticeable central toth on the margin of the hindwing. 
Both the white, narrowly black-edged cell-marks crescentic or comma-shaped. Cedar Bay, S. of Cooktown 
(A. S. Meek), 1 <$ in the Tring Museum. The hindlegs are somewhat damaged, but I do not think they can 
ever have been so densely clothed as those of porphyropis E; if not, my suspicion (derived from the shape 
and facies) that this is a distinct species, is confirmed. 
microsticta. A. microsticta Turn. Expanse 34 mm. Palpus 4 times as long as diameter of eye, terminal joint 
Y 2 second joint. Forewing with apex acute, slightly produced; ochreous whitish, with very sparse irroration; 
a postmedian series of minute vein-clots; a terminal series between the veins. Hindwing with termen slightly 
bowed; markings the same. Underside as upper, but slightly tinged with rosy, the dots paler than above. 
Lowe Howe Island, 1 $. Unkown to me; as Turner says, it is “impossible to be certain of the genus” (sub¬ 
genus) in the absence of the <$; he writes “ Br achy cola ?” but I suspect it is an Eremocentra near porphyropis. 
20. Genus: VBylliarisi Walk. 
Palpus rather long and slender, with smooth, exposed 3rd joint. Antenna in the <$ pectinate, but 
rather shortly. Hindtibia in both sexes with terminal spurs only. Forewing with simple areole, 5th subcostal 
from near its apex, 1st—4th long-stalked from its apex, 1st median arising far from 3rd radial (as also on hind¬ 
wing). Hinclwing with termen almost smooth. Notwitstanding its entirely changed pattern, certainly an off¬ 
shoot of Anisodes; the genitalia confirm the relationship indicated by other characters. Exclusively Indo- 
Australian. 
uniformis, B. uniformis Swinh. (= baletensis Schultze) (15 i). The only Malaysian species (or race), recognizable 
by its narrow dark borders; the yellow ground-colour inclines to become whitish on meeting the distal border. 
Sumatra (type), Java, Borneo, Luzon and Celebes. Schultze, who treated his Luzon capture as a new genus 
(Silvaspica) and species, reports it as flying in large numbers during the whole day. 
marginata. B. marginata Walk., from Ceram, has the borders broad. I measured them in Walker's type $, 
as there was at one time some confusion about the synonymy. That of the forewing is 8 V 2 mm at the 5th 
subcostal, 6 at the 1st radial, 4 at the 3rd, thence (and on hindwing) approximately 3 mm, weakly subcrenu- 
atrimargo. late throughout. - atrimargo Warr. ( latimargo Warr.) (15 i), the Papuan race, has the borders about 
1 mm wider. The type of atrimargo, from Fergusson Island, and that of latimargo, from Etna Bay, are not 
racially separable. 
lucida. B. lucida Warr. (15 i) represents marginata on New Hanover and it is very doubtful whether it should 
be regarded as anything more than a race. The breadth of the borders is nearly as in m. marginata, in the 
$ a little broader than in the <$; but on the forewing their shape is different, so that they meet at almost a 
circumducta. right-angle. circumducta Pagenst. (= circumdata Swinh.) is larger and less deeply coloured, the border 
of the hindwing in the (type) $ not broadened, those of the forewing a little more rounded where they meet.
