this, as well as from our description in Vol. 4, p. 127, it will be seen that our original figure (pi. 7 d) was based 
on a misidentification. 
S. delicatula Warr. (6 e) has no very close relationship to decidua Warr. The antennal joints project delicatula. 
less and the hindtibial pencils are white and less strong, the tarsus less shortened. Larger and much better 
marked; the broad, sinuous subterminal is markedly thickened between the radials and near the anal angle, 
its proximal shade strong (much as in bisela ta), its distal weaker, more recalling trigeminata. Punjab and Kashmir. 
S. denudaria Front (6 e). Here again, as with decidua, our original figure (Vol. 4, pi. 7 a) is altogether denudaria. 
at variance with the description and the specimens on which it was founded. We therefore substitute a $ from 
Ningpo, April 1886, which, though more ochreous-tinged than usual, is in better condition than most captured 
specimens of this obscure little Sterrha. It seems to be widely distributed in China. 
S. osthelderi Wehrli (6 c). Suggestive in shape of ossiculata (Vol. 4, pi. 4b), but much smaller; in struc- osthelderi. 
ture, colour and markings nearer dilutaria (Vol. 4, pl.4f), though slightly greyer. Ciliation of o antenna rather 
longer (a little over diameter of shaft); hindtibia spurless, not thickened and without pencil, tarsus 4 / 5 tibia, 
thus shorter than in dilutaria. Lines indistinct, straighter than in dilutaria. Marasch, N. Syria, May and June. 
S. dilutaria Hb. ab. anastomosaria Preissecker (Vol. 4, pi. 4 f) is not yet known from Denmark; Klocker's dilutaria. 
dilutaria is juscovenosa. — Antemedian and median lines of the forewing more or less joined together. The anasioni g C ' ir i a 
type was from Lower Austria. 
S. juscovenosa Goeze ab. anastomosaria Preissecker. The corresponding form to that noted under dilu- anastomo- 
taria and others to which Preissecker hasapplied this “collective name”. Also from Lower Austria. — corsula , saria - 
x x corsula . 
Schawerda. Described as a race from Corsica, smaller than the type, grey-yellow rather than brown-yellow, 
the markings weaker. Schawerda expects it to occur also on Sardinia, but the Tring Museum examples 
from that island scarcely bear this out, wdiile some from St. Baume (S. France) seem to be virtually cor¬ 
sula. Perhaps an aberration rather than a race. 
S. nitidata H.-Sch. (= tectaria Leech, nec Walk., nitidulata Stgr., nec H.-Sch .) (Vol. 4, pi. 4f). A re- nitidata. 
markable deviation from the normal forewing venation of Sterrha has not, I think, been hitherto pointed out, 
but is constant throughout the wide range of nitidata: one of the subcostals is always wanting, the 1st and 2nd 
being apparently coincident, rather remote from the costal; usually the 5th subcostal separates, beyond 
this co-incident vein, occasionally just before it (in one examined Ussuri <$ well before it). Lord Rothschild's 
Herkulesbad $, recorded in Dr. Rebel's faunistic list (“cj” is a misprint) is an error of determination, as is 
shown not only by the venation but also by the cell-dots and other details; probably it is a curious aberration 
of deversaria. 
S. promiscuaria Leech (6 b) is not, as I suggested, a discoloured specimen of nitidata but a good spe- promiscua- 
cies, with normal Sterrha venation. I still know only Leech’s $ type, but Dr. Sterneck has seen 3 from ria 
Pekin, taken in June, and confirms its validity. 
S. argilata Guen. (7 b). The original $ (see Vol. 4, p. 115), which we now figure, remains unique. Dr. argilata. 
W EHRLi has re-examined it and provisionally shares the opinion of Staudinger and others that it is a good 
species. On account of its acknowledged similarity to nitidata, from which it is distinguishable chiefly by its 
d arker, browne r colour and straighter, less dentate lines, I suggested that he should 
investigate the subcostal venation; he reports that all the veins are present, their arrangement not exactly as 
in typical deversaria, which, however, varies in detail. Underside almost exactly like that of a lighter and some- 
wdiat larger Pekin nitidata with which he has compared it. Culot's figure makes the lines of the upperside appear 
somewhat too thin and sharp, the ground-colour a trifle too light. 
S. degeneraria Him. ab. affumigata Dannehl (= affumicata Dannehl). Lines more blackened than in the affumigata. 
normal form, median area more heavily powdered.'with blackish. Tyrol and Karawanken; probably, however, 
quite widely distributed. — Hubner’s degeneraria (type figure) approaches this, but is not very satisfactorily degeneraria. 
executed, the postmedian and both subterminal lines almost certainly drawn too black; its ground-colour is 
flushed with reddish, yet not so red as in the floridaria forms. Probably it is copied from a large 2nd-brood 
example, in which case “var. (gen. II) aestiva” A. Fuchs is synonymous. -— That author emphasizes as distinc¬ 
tive between the two generations, in addition to the larger size of gen. I (length of a forewing about 13 mm, 
as against 11 mm in gen. II), its greenish grey-yellow tone and blackish brown median band, and proposes 
a provisional name: var. (May-generation) vernalis A. Fuchs. As his conclusions are approximately corroborated vemalis. 
by most Central-European material, they may be accepted, although (as has been pointed out in Vol. 4) the 
variation is considerable and, especially in S. Europe and N. Africa, very complicated. — meridiaria Mill., meridiaria. 
which retains in general an olivaceous tinge in the light grey ground-colour but has the band lighter and 
redder than the name-type, can hardly be united with either of the foregoing forms. — alticolaria Schawerda alticolaria. 
(= altivolaria Schawerda , nec Reisser), from the mountains of Corsica, is said to be much smaller than the coastal 
forms (which include a large percentage of ab. floridaria) and with very slight or weak markings; ground-colour
