the which is wholly ochreous, not (as in semisericea and actiosaria) largely mixed with fuscous. Lines 
rather thick, both the ante- and the postmedian of the forewing darkened at costa and hindmargin. Warren 
further notes that the terminal dots are placed on the wing-margin, not, as in most Sterrha, on the fringe 
close to its base; strictly speaking, they encroach slightly on to the base of the fringe, but the differentiation 
is interesting and valuable. Ceylon. — trettesensis subsp. nov. Less glossy, with increased (though minute) 
dark irroration; lines moderate to rather strong, the postmedian slightly angulated outward at 1st radial 
and sinuate between the radials. Trettes, E. Java, 3000 feet, May 1932 (J. P. A. Kalis), 4 <3$, 1 $ in the 
Tring Museum. Possibly a separate species. —• neanica subsp. nov. (23 c). Also less glossy than the name-type, 
but in addition so different in colour that it may well be another species; the $ (here figured) is perhaps even 
more reddish than profanaria and rubellata and the Jrf, although not cpiite so extreme, approach that tone. 
The abdominal margin of the hindwing is perhaps a little less elongate than in c. comparanda. North Borneo: 
Tenom (E. Wahr), 2 JJ, 1 $ hi the Tring Museum. —- Single specimens of comparanda (sens, lat.) from Sam¬ 
ba wa and Luzon, both discoloured or worn, show that the assemblage has a wider range, but are not fit for 
describing. 
S. plioenicoglauca Hmps., a $ from Maskeliya, Ceylon, looks like an almost melanic aberration of one 
of this group, rather dark brownish drab, only the distal margin and fringes and a slight subterminal line 
pale; fringe-dots placed as in actiosaria, otherwise the shape and the strong gloss would make one think of 
comparanda. 
S. themeropis West (23 d). Colouring about as in actiosaria or slightly less yellow-brownish (more 
grey-brown), more sharply marked, both above and beneath. Apparently variable; median line slender, 
postmedian slightly curved and subcrenulate, in the unique type (a $ from Haight’s Place, Pauai, Benguet, 
Luzon) developed into a very narrow band, appreciably pale-edged distally. — ethima form. nov. (22 m) is 
the ordinary form from the type locality, large, with the lines almost equal in expression, subterminal shades 
appreciable. The hindleg seems still more heavily tufted than that of actiosaria. As it is not absolutely 
certain that it is conspecific with West’s type, 1 have given it a name which it can in any case retain. Type 
series in the Tring Museum. — obrepta subsp. nov. As large as ethima and with the same hindleg structure and 
broadish forewing, but with more of the brown tone of actiosaria ; cell-dots relatively large. Postmedian line 
generally the strongest, but a rare aberration has a strong median line, recalling that of obliquilinea. Kinabalu, 
recorded by me as themeropis. 
S. indeprensa Prout (23 d). Ciliation of antenna about as in the actiosaria group. Hindtibia of the <$ 
dilated, with strong, pale hair-pencils, the tarsus minute. Forewing with termen straightish; areole moderate, 
the 1st subcostal stalked just beyond it; hindwing strongly convex, rather prominent about the 3nd radial 
and 1st median. The pale ground-colour mostly with greyer suffusion, the band between median and post¬ 
median remaining clear; distal area relatively dark, suggesting that of palniensis. Underside of fore wing with 
the contrasts still stronger. Darjiling, not uncommon. 
S. palniensis Prout (23 d). Hindleg of not unlike that of indeprensa ; antenna with the joints tri¬ 
angularly projecting, ciliation nearly 2. A greyer, rougher-looking insect, occasionally more brownish. Palni 
Hills. 
S. marmorata Hmps. (23 d) more recalls, in its mottled wings and the shape of the subterminal line, 
a rather long-winged member of the eburnata group of the Palaearctic and African Regions, but has a some¬ 
what smoother wing-texture and a much specialized hindleg; the tarsus is modified into a (stridulating ?) process, 
with the tibial pencils on two sides of it. Described from Cuddapali; since received from Pusa and from Mughal 
Sarai, Benares. Probably rather strongly variable. 
S. aequisinuata Warr. (23 d). Another strongly glossy species; easily distinguished by the conspicuous 
strengthening of the subterminal shading at the hindmargin, where it forms a dark spot, followed by a smaller 
one at the termen; the lines on the forewing arise from dark costal marks. Costal edge of forewing and a great 
part of the fringes (both wings) more tinged with ochreous. Structure about as in actiosaria. Kliasis; once or 
twice also in Bhotan and N. Burma. 
S. decidua Warr. (= holosericeata Butl., err. det.) (Suppl.-Vol. 4, pi. 6 e). Similar to the Palaearctic 
biselata extincta, but smaller and with the hair-pencil of the hindtibia a good deal less strongly developed, 
brighter ochreous. Colour lighter, with scarcely any dark irroration, markings weak, excepting the cell-dots; 
even the dots at the base of the fringes very small and weak. N. W. Himalayas, the type from Dharmsala. 
S. denudaria Prout (= nudaria Pung., err. det.) (Suppl.-Vol. 4, pi. 6e). Somewhat narrower-winged 
than decidua ; whitish ochreous, the cell-dots and dots at base of fringe very small or wanting, lines very slender, 
commonly obsolete, in which case the wings are almost unicolorous, only the forewing with the costal margin 
more definitely ochreous. Leg-structure much as in decidua. Distributed in China, the types from Ningpo. 
Possibly a race of decidua.
