26 APOSTATES —SYMMACRA. By L. B. Prout. 
and more tremulous, the median line sinuous; 2nd subcostal of the forewing much more shortly stalked than 
any bisinuata which I have examined, but this character may be inconstant. 
Note. — “ Phyletis" monbeigi Obth. is a Heterolocha and will be discussed by Wehrt.i later. 
2. Genus: Apostates Wan. 
A. soUtaria Christ. (Vol. 4, pi. 7 a) I have seen several further specimens, from various parts of the 
Transcaspian Province, but am still unacquainted with the 3, which has probably some different habits or 
times of flight. To the localities given in Vol. 4 should be added Bokhara. The peculiar subcostal venation is 
evidently constant. 
3. Genus: Taiiaotrichia Wan. 
No new Palaearctic species of this genus has yet been discovered; that orientis Prout (Vol. 4, p. 44, 
pi. 7 a) has no close relationship to Ph. bisinuata (4 b) will be seen from the notes and figure now given of 
the latter. 
4. Genus: Dlscoglyplia Wan. 
An Indian genus, or perhaps subgenus of Organopoda Hmps., with most of the characters of Somatina, 
but with more Rhodostrophia- like genitalia (a long club-heacled uncus, gnathos present, no true mappa, etc.) 
and Organopoda-\ike $ hindleg (the tibia with strong pencil and one or two spurs or spur-like processes, the 
tarsus proximally swollen and hairy). From Organopoda it differs in the rather short palpus, though with rela¬ 
tively well-developed 3rd joint, and in having the 2nd subcostal of the forewing (dividing-wall of areole) stalked 
with the 3rd—5th. “ Organopoda ” atrisparsaria Wehrli should be referred here rather than to Organopoda. 
D. atrisparsaria Wehrli (= brunnearia Ob., nec Leech) (4 b). Recognizable at once by its ground-colour, 
the black costal suffusion of the forewing, strong blackish median shade of both wings, etc. Described from 
E. China, it has since been taken in Szechuan (Kwanhsien and Omei-shan). 
5. Genus: Somatina Gwen. 
Although this genus shows some characters in common with the Rhodostrophia group, it is probably 
misplaced here, and comes nearer to Scopula except in that the areole is generally double; in particular the 
<$ genitalia show a well-developed mappa, though not the cerata of Scopula (see Vol. 4, p. 51). It can scar¬ 
cely be regarded as Palaearctic and I know of no Palaearctic additions since the appearance of that volume. Even 
the little-known centrojasciaria Leech (Vol. 4, pi. 5f) may well prove to be a Discoglypha , related to atrisparsaria. 
6. Genus: Craspediopsis Wan. 
This is also shown by the genitalia, as well as by the facies, to be nearer to Scopula than to Rhodo - 
strophia. Both the mappa and the cerata are developed, there is no gnathos and only the uncus and its ar¬ 
mature suggest that it may be a derivative of the Rhodostrophia group. 
7. Genus: l>ltlieco«les Wan. 
(see Vol. 4, p. 46; Vol. 16, p. 49.) 
D. pseudacidalia Sterneck (= pseudoacidalia Sterneck) (4 b). I have not seen the 2 of this species, for 
which its author suggested the provisional subgeneric name of Pseudacidalia (nom. praeocc., 1894), chiefly 
on account of its yellowish-white, not green, ground-colour and its altogether Scopula- like facies. $ antenna 
with rather long fascicles of cilia, hindtibia with a very strong brown-red hair-pencil. Forewing with 2nd sub¬ 
costal arising from very near (or at) apex of areole. “Expanse 26 mm. Aspect of the nigropunctata group 
of Scopula , but with scarcely bent margin of hindwing.” W. China, the type from Ta-tsien-lu. 
D. erasa Wan. (= vacua Swinh.) (4 b). A few further examples of this are now known and the syno¬ 
nymy is confirmed. 
8. Genus: Syminacra Wan. 
Characters nearly as in Dithecodes but with the areole simple; here, however, it is small and the first 
four subcostals are long-stalked beyond it, as in the Cosymbia group. Typically the hindtibia has 2 spurs, 
but in solidaria only one is developed. A small Indo-Australian genus. 
S. solidaria Guen. (4 b), one of the most widely distributed Indo-Australian Geometridae, will be dealt 
with in Vol. 12. —- sinensis subsp. nov. (4 b). All the Chinese specimens yet known to me are considerably larger 
than the typical forms (Ceylon, India, etc.) and in general still more weakly marked. Large forms occur again
