234 STERRHA. By L. B. Prout. 
is probably nothing more than an aberration of triangularis $, virtually unicolorous; possibly, however, the 
$ to deleta. 
delete.. S. deleta Wileman, only known in 2 not very fresh <$<$, is very close to unmarked triangularis, with the 
same glittering scaling beneath and on the fringes, but with the hindwing less produced to tornus. here appar¬ 
ently less tufted. Formosa: Ivanshirei (type) and Taiko. 
S. phoenicoptera Hmps. Areole very small. Hindwing of the £ even more acutely produced posteriorly 
than in triangularis, termen from 1st radial hindward folded over beneath. Coloration more reddish. Ceylon 
(loc. typ.) and Bombay. Hindleg not quite so heavily clothed as in opsitelea. The name-typical race has the 
pale bands quite narrow. — tuita subsp. nov. (23 li) lias the bands broader, the outer one, at least, almost twice 
as broad as in ph. phoenicoptera. Knala Lumpur (H. M. Pendlebury), both sexes taken at light, besides 1 $ 
on Bukit Kutu. 3500 feet; type in the British Museum. A similar in the Tring Museum from Trettes, E. Java. 
opsitelea. S. opsitelea Front (23 h). Hindleg of $ very heavily tufted, tarsus weak, curved. Colour somewhat 
variable, the $ paler, notably in a band between the median and postmedian lines, which is sharply contrasted 
with the band-like antemedian suffusion. The q is coarsely scaled and less clearly marked, but with the 3 buff 
costal streaks more conspicuous; readily distinguished from phoenicoptera by the shape, the abdominal region 
of the hindwing folded, with a fringe of hair. Malay Peninsula: Kedah Peak. Subsequently taken in the Larut 
monodia. Hills, Perak. - monodia subsp. nov. is apparently a separable race, duller and more uniform in aspect and less 
variable, the dark antemedian band and costal commencement of postmedian less strongly developed. $$ are 
not rare in the Khasis, but the only $ yet known (collected with 1 9) is from E. Pegu (Doherty); I therefore 
make this the type locality. 
ziczaccita. S. ziczacata Warr. (23 h). The type of a superfluous genus Thysanotricha Warr. . which was merely 
diagnosed thus: “The hindwing of the $ lias the abdominal margin thickened and contorted, slightly swollen 
at middle; from near the base of the wing rises a pencil of hairs, contorted parallel to the margin, under the 
fold of which they are sometimes hidden/'" The midlegs are lost in the only known $ and will perhaps prove 
to be hairy (sect. Xenocentris ); hindleg of $ slender, tarsus aborted, antenna with moderately long and even fas¬ 
cicles of cilia. A simple little white species, the 3 dark lines strengthened by vein-dots. Ysabel Island. 
purpurea. S. purpurea Hmps. (23 h). the type of a “genus ” Lophophleps, has approximately the coloration and 
pale bands of triangularis and numerous other Sterrha. but is unmistakable in the $ by reason of the posteriorly 
strongly lobed distal area of the forewing and the curled and roughly clothed apical region of the hindwing, which 
wing, in this sex only, has the costal vein anastomosing to near the end of the cell. The $ resembles 
a small dark triangularis but is somewhat rounder-winged; lines of foreAving broadened costally. Known 
from Ceylon. India. Selangor and Formosa, the type from the Nilgiris. 
andamanica. S. andamanica sp. n. (23h). In the absence of the the position of this little species is somewhat 
uncertain, but I judge from its small size (ca. 17 mm) and dark colour that it is probably related to purpurea 
(very likely a race) rather than to triangularis-, colour still deeper, outer band broader, pale spots close to termen 
developed. S. Andamans: Mt. Harriet, etc., at light. 4 $$ in my collection and that of the Agricultural Research 
Institute, Pusa. 
trypheropa. S. trypheropa Meyr. (o - floccosa Pagenst., $ = angustipennis Warr.) (23 h $). Again a potential 
genotype. Meyrick having proposed for it the name Mnesterodes. Avhich has been adopted by Turner. Hind- 
Aving of o “with a large glandular swelling beneath in middle of disc and a long extensile pencil of hairs from 
base of costa above”; the foreAAdng beneath has a glittering, scaleless area to accommodate this pencil. Midleg 
simple, hindtarsus of S much shortened. Fore wing Avitli all the subcosta Is stalked beyond the areole. Sexual 
dimorphism strong. Apparently a much more extreme development from the Cacorista stock (see Vol. 16. 
p. 80, S. amputata). Distributed from N. Australia and Timor to the Bismarck group ; the 3 named types respect¬ 
ively from Port Moresby, N. Queensland and New Britain. 
robusta. S. robusta Warr. (23 1). $ antenna dentate, AA'ith long fascicles; midtibia somewhat hairy, liindtibia 
with strong, predominantly dark pencils, the tarsus much as in the actiosaria group or carnearia. The distal 
margin of the hindwing is rather strongly convex, though not ventricose as in carnearia. Seems to link that 
group with "Xenocentris'’, but is still little known; Philippines: Negros, only the type. 
trisetata. S. trisetata Prout (Suppl.-Vol. 4, pi. 6 d). This and the folloAving species (as far as villitibia) perhaps 
form a natural group ( Xenocentris Meyr.), characterized by the hairy midleg of the <§. often correlated with 
highly specialized scaling on the hindwing beneath, trisetata, which was described from Japan, suggests a 
miniature biselata Hufn. or invalida Butl. of the Palaearctic Region, but is slightly narrower-winged and with 
plioenico- 
ptera. 
tuita.
