S. testacea Swinh. (23 i). In this species and those which follow (as far as macrospila) the areole is 
wanting, all the 5 subcostals stalked together. This specialization has clearly arisen independently, but there 
may be some practical convenience in grouping then together. The $ type of testacea, from Poona, has the 
dots of the postmedian, also the median shade of the hindwing, rather stronger than in the topotype here figured, 
but otherwise agrees. A diminutive form form Sokotra is also a good match, especially one of the the $ 
which apparently belongs to them has unfortunately lost its hindlegs. 
S. egenaria Walk. (23 1). Very like gemmaria (23 f), the shape on the whole not quite so extreme, 
the colouring not quite so variegated. The typical form is smaller, but this is not a constant distinction. Nearly 
always it can be separated by the absence of the areole, but I find that even this is not absolutely constant, 
out of 5 specimens collected together at Klondyke, Luzon, one shows on both forewings a very small, very nar¬ 
row areole, of which I have seen no remnant in any other example. Hindleg of the $ dilated and heavily 
clothed, with the exposed (smooth) part of the tarsus extremely short. Borneo (type from Sarawak), Luzon 
and Formosa; variable. 
S. pulchrifascia Hmps. (23 k), founded on a $ from “Sikkim”, 1800 feet, has not been since matched, 
but may possibly be a local form of egenaria. Rather large and variegated, the bands narrow, their edges more 
fuscous than red; the median of the hindwing is more definitely a line than in any other of the group. A $ 
from Muang Awm, Laos (900 m) which is probably conspecific, has the cell-spot of the forewing better developed, 
the half-band broader, its proximal part forming a sinus between 2nd radial and 2nd median; the hindwing 
with cell-spot and hind median spot large, cinnamon, the postmedian heavily dark-clouded from costa about 
to 2nd radial. 
S. onchnophora sp. n. (23 1). Wings somewhat narrower and more pointed than in the allies, the cell- 
spots standing out conspicuously, that of the hindwing elongate, tapering proximally. Red-brown suffusions 
ample, on the hindwing extending nearly to the base, on the forewing showing some extensions from the (proxi¬ 
mally ill-defined) “half-band” into the apical region. India: Pusa, 23 March 1916 (FT. Bahadar), type $ in my 
collection; ? Travancore (Place), a much damaged <$ in the Tring Museum, probably (by its narrowed wings 
and extension of the red-brown cloudings) the same species, but impossible, to identify certainly. 
S. craspedota Prout ( = marginata Swinh., nom. praeocc.) (23 k). A neat little species, nearest like proxi- 
maria Leech (Vol. 4, pi. 7 c) but considerably smaller and easily distinguished by the absence of the areole. 
Filiation of the antenna about as long as diameter of shaft, hindleg with the tarsus enlarged into a strong, 
clubbed process. Assam (type from Cherrapunji), Tonkin, the Andamans, Malaysia and Bali. There may be 
some slight geographical variation. 
S. celativestis Prout. At first sight scarcely distinguishable from craspedota. Venation the same. Hind- 
femur more swollen, purple-reddish. Forewing with a pronounced costal spot (sometimes well developed, 
however, in craspedota also), beneath as far as the postmedian strongly suffused with reddish grey. Hindwing 
beneath with an extended fringe of long hair from just behind the median vein and the base of its 2nd branch, 
directed hindward and outward so as to cover most of the hind area of the wing except the tornus. Bukit Kutu, 
Selangor, 3500 feet, only the type known. 
S. chrysocilia Hmps. (23 1). A very distinct species, with nearly the shape of a “ Janarda” (compare 
acuminata), the forewing venation of the present assemblage, “the costa clothed with rough hair” and the 
coloration reminiscent of such species as flavisinuata Warr., etc., the straight dark line on forewing distinctive. 
Antenna of $ serrate-fasciculate, hindleg much reduced, with strong hair-tufts, hindwing with 3rd radial and 
1st median shortly stalked. Nilgiris, only the type S known. 
S. macrospila Prout (23 k). A very small, but attractive species, very easily recognizable from the 
figure. The variegated and in part metallic colouring of the postmedian patches suggest a possible relation to 
gemmaria or egenaria pulchrifascia. In addition to the loss of the areole, it shares with chrysocilia the stalking 
of the 1st median of the hindwing. Filiation of the shortish-moderate, hindleg weak, strongly tufted. Bombay 
(type), Foimbatore and the Andamans. 
S. micra Hmps. (23 k). Flearly related to macrospila, venation of hindwing the same, but the forewing 
has retained the areole. The different disposal of the dark markings makes confusion impossible. Hitherto 
only known from Feylon. 
S. bilinea Swinh. (23 k). Small and exceptionally narrow-winged, this is at present the only Indian 
l’epresentative of the lilliputaria group of Africa (see Vol. 16, p. 81 and pi. 7). Their most noteworthy features 
are the long cell of the forewing and the strong anastomosis of the costal vein of the hindwing with the cell 
and although this latter has not proceeded quite as far in bilinea as in its African relatives it is usually quite
