median area of the forewing restricted and ill-defined (partially obscured by irregular dark irroration) and 
generally some slight grey suffusion in the abdominal region of the hindwing in addition to the constant, though 
small, basal shading. It is this form which, in Vol. 4 (p. 204) I considered to bear “an extraordinary resem¬ 
blance" to the Sikkim Amnesicoma bicolor Warr. The two are certainly very similar, but perhaps I over-em¬ 
phasized the likeness; bicolor, which is not unlikely to be found in W. China, is on an average smaller, its hind¬ 
wing with broader border, darker and more extended suffusion at the base above, some basal suffu¬ 
sion also beneath (tonchignearia here remains white to the base) and a larger white subapical spot 
on each wing beneath. ab. albiplaga nov. (Vol. 4, pi. 6 1, as bicolor ) may denote the form of tonchignearia (in 
my experience quite frequent) in which the white median patch of the forewing above is clean and well-defined, 
comparable to that of typical dejeani (Vol. 4, pi. 6 1). Type a $ from Che-tou in the Tring Mus. 
49. Genus: Amnesicoma Warr. 
(See Vol. 4, p. 204.) 
In the Tring Museum I merged this so-called genus in Photoscotosia as section A (without the <§ hair- 
pencil), although the few known species evidently diverged therefrom at different points, so that neither as 
section nor as genus can it be regarded as a perfectly natural group. For provisional taxonomic purposes its 
continued conservation is convenient. 
A. simplex Warr. (lOe), the genotype, calls for mention here, as the original series came from Goorais 
Valley, though not exactly localized in the published description. It is unmistakable, being the only yellow¬ 
hindwinged Amnesicoma yet known and bearing some resemblance to Ph. miniosata , to which (quite inexcusably, 
however) Hampson has sunk it. 
A. vacuimargo Prout (10 e). Overlooking the expanded costa of the hindwing, I described this as an 
Ortholitha “in some respects intermediate’’ between pulchrata (Vol. 4, pi. 8 c) and adornata (7 k) and thus mis¬ 
sed its true affinities. Palpus short. Very similar to Ph. achrolopha (Vol. 4, pi. 5 h) but without the hair-pencil, 
forewing paler, without cell-dot. distal area very weakly marked, hindwing white. Sinin Alps, Tibet. The 
specimen figxned as oberthuri (Vol. 4, pi. 5 k) is quite evidently a slight aberration of vacuimargo. 
50. Genus: Teleiiomeuta Warr. 
(See Vol. 4, p. 206.) 
T. punctimarginaria Leech (= inconspicua Bastelb., as Triphosa ) (Vol. 4, pi. 11 h). I was not aware 
of the synonymy when Vol. 4 was published, but a manuscript description and figure made by Warren from 
Bastelberger's Formosan type sxxbseqxxently directed my attention to it. The geographical distribution extends 
to W. China. 
51. Genus: Hysterura Warr. 
(See Vol. 4, p. 206.) 
.S’ 
The particular^ previously given require some emendation. Warren erected two genera simultaneously, 
Hysterura for multifaria Swinh. and Lygridopsis for cervinaria Moore, the former having page-priority and 
showing the special characteristics in the highest degree of development: forewing beneath in the with a bed 
of pale hair at hindmargin, reaching almost to the anal angle and to the 2nd median vein; hindwing in the 
with an angle or small tail between the 3rd radial and 1st median and with the abdominal margin tufted with 
coarse dark hair. Lygridopsis ( cervinaria only) was differentiated by the simpler shape of the hindwing (“some¬ 
what undulate”, Vol. 4) and the smaller pencil of hair on the forewing beneath (about as in Lygris). Actually, 
however, each of the species known to me has its own $ characters; as regards the pencil of hair I can now say 
that it is wanting in literataria, also in the related form from Yulongkong described belcw. Two Indian species, 
moreover, have been confused under multifaria and it is probable that declinans Stgr. (the type of yet another 
generic name, Eulygris Stgr., based on the same characters as Hysterura) may represent a third. 
H. multifaria Swinh. (Vol. 4, pi. 12 a). Our figure well represents the except that it does not show 
the pronounced angulation of the hindwing. As I now think the sinking of declinans highly improbable, I 
know only one Palaearctic specimen of multifilaria, a $ from Gulmarg, Kashmir; in this sex the hindwing is 
not angled and is usually paler than in the <$. Sterneck records (without detail as to structure) one example 
of “ multifaria" from Ta-tsien-lu. 
H. declinans Stgr. Smaller, length of $ forewing 14 mm, antemedian acutely exangled in cell, post- 
median oblique inward at costa, subterminal spots small. Sutschan, l tf, still unknown to me. 
H. hypischyra syt.n. (10 e). Larger than literataria (Vol. 4, pi. 13 n), hindwing distinctly elbowed at 
1st median (though much less than in multifaria Swinh. <$), a strong tuft of spreading hair on abdominal margin
