STERRHA. By L. B. Prout. 
221 
S. humeraria Walk. (= cerussina Bull.) (22 i). Probably related to grisescens. Hindleg similarly formed, humeraria. 
Less glossy, the subterminal dark patches weaker and more separated, characteristic dark shading present at 
the costa of the forewing, especially proximally. N. W. India. 
S. inaudax Prout (22 i). Probably nearest to delicatula Warr. and dilutaria Hbn. (Vol. 4, pi. 4 f), slightly inaudax. 
narrower-winged, the costa of the forewing a little straighter. Hindtarsus of $ almost as long as tibia. Lines 
weaker than in delicatula, the postmedian straighter, minutely dotted on the veins; subterminal and its shades 
much as in dilutaria. Hindwing marked much as in dilutaria, termen less smooth, more as in delicatula. Kumaon 
(loc. typ.) and Dalhousie. 
S. delicatula Warr. (Suppl.-Vol. 4, pi. 6 e). Expanse 19—22 mm. Hindwing with the termen somewhat delicatula. 
sinuate between the radials and again, though very feebly, near the anal angle. Distinguishable form the other 
similar glossy, yellow-whitish Sterrha by tne sinuous band-like shade proximal to the subterminal on both 
wings; though narrow and not very dark, this seems always well developed. Hindtarsus of J little shortened. 
Punjab and Kashmir Valley, the type from Dalhousie. 
S. carpheraria Hmps. (= unipuncta Swinh.) (22 i). Less small, relatively somewhat ampler-winged, hind- carpheraria. 
wing with termen scarcely sinuate. Very distinct in the bright yellow margins, obsolescence of the lines, slen¬ 
derness and indistinctness of the subterminal shade, intensity of the blacK. cell-dots, etc. Distribution simi¬ 
lar; both the types came from Kashmir. — ab. concatenata nov. is a striking and rare form (though recurrent concaienata. 
at Gulmarg) with a distinct, narrow, grey-brown band on both wings, marking the proximal boundary of the 
subterminal. 
S. muricata Hufn. (Vol. 4, pi. 4 b) minor Sterneck (22 i). Generally a good deal smaller than the well- minor. 
known European race, though an occasional aberration can reach the size of that and no other distinction has 
yet been noticed. Inhabits Japan, Ussuri, Corea and a considerable part of China, perhaps also Saghalien; 
chiefly Palaeaarctic, but its occurence in Szechuan makes it desirable to notice it in the present volume. 
S. sinicata Walk. (22 i). Apparently a rare or much overlooked species. $ hindleg slender, not long, sinicata. 
tarsus almost as long as tibia. Smaller and narrower winged than muricata and not so bright; broader than 
marcidaria (22 k), less glossy, the yellow brighter, the pink markings far more extended, the subterminal band 
near the termen, sharply contrasting with the clean yellow border. S. E. China and Formosa, the type from 
Foochow, Fokien. 
S. flavisinuata Warr. (22 i). Colours about as in muricata , shape entirely different, yellow border of flavisinuala. 
forewing strongly sinuous-edged proximally: <$ more pinkish, $ (except where the ground-colour meets the 
yellow border) much darker, purple. Hindleg of less slender than that of muricata but with similar proportions 
(tarsus not abbreviated). Khasis. 
S. roseolimbata Pouj. (Vol. 4, pi. 5 d). Another brightly coloured species but larger, the ground-colour roseolimhata. 
stramineous, the distal area rose-pink, with interrupted subterminal of the ground-colour; costal margin of 
forewing rosy, with some dark irroration. Hindtarsus not abbreviated. W. China. 
S. impexa Bull. (Vol. 4, pi. 7 c). A small, glossy relative of jakima (see below), the lines and cell-dots impcxa. 
always weak or wanting, a narrow dark submarginal band always developed, on the hindwing close to (com¬ 
monly reaching) the termen, on the fore wing receding a little from the termen in its anterior half, so as to leave 
a very narrow terminal half-band of the ground-colour. Hindtibia of the rather long, clothed with hair, tarsus 
shortened. Described from Japan and cniefly Palaearctic; known, however, from Ningpo and Szechuan, 
paraula Prout (22 i), from Formosa, is perhaps merely a race of impexa , though I noted the <$ hindleg as “longer- paraula. 
haired”. Hindwing perhaps not cpiite so fully rounded. Both wings with markings less obsolete, somewhat 
more reddish or purplish, distal band not quite so near termen. Joannis records it from Tonkin. 
S. jakima Bull. (Vol. 4, pi. 5 b). Markings somewhat as in roseolimbata, colouring much duller; ground- jaldma. 
colour more brownish, borders rarely with any definite pinkish tinge, that of the forewing usually clouded with 
fuscous in its posterior part and often narrowly so nearly to costa, the rest of the anterior part remaining of the 
ground-colour. Postmedian line conspicuous, median often conspicuous, on forewing, but quite slender, generally 
strengthened at costa. Hindleg not hairy, tarsus not shortened. Range about as that of muricata minor. — ab. 
obliterata Leech lacks the lines of the upperside and has the dark border weakened. obliterata. 
S. parallela Wile.ni. & South. (22 i). Closely similar to jakima, but with the hindwing reproducing the parallcla. 
distal markings of the forewing . Antennal ciliation of the much shorter, hindtibia dilated, with long pencil, 
tarsus about y 2 . Formosa. 
S. charitotes Prout (22 k). Colouring of parallela, forewing with termen more oblique, hindwing rela- char notes. 
tively smaller, more weakly marked; postmedian line of forewing less sinuous. Antennal ciliation of the S 
simple; hindtarsus slender, not shortened. Khasis. Possibly a subspecies of the following.
