cuts through to the 3rd postmedian, as also in obliquisigna (Vol. 4, pi. 13 f, as marmoraria). — marmoraria marmoraria. 
Leech (16 e) is a small, heavily marked race (or perhaps aberration) with darker hindwing. As our first figure 
(cited above) represents a Yatung obliquisigna, which Hampson in error had determined as marmoraria, 
we now figure the unique type. — ilara subsp. nov. is another small form (26 mm), similar to marmoraria, ilura. 
less dark (especially the hindwing, median area broader, reddish apical suffusion duller (more as in C. laria), 
postmedian of hindwing much less sinuous; cell-mark of forewing small. Honzawa, Japan, 26 July 1916, 1 
in the British Museum collection. 
D. blomeri Curt. (Vol. 4, pi. 10 g, h). Statjdinger's record of Japan as a habitat (copied by me blomeri. 
in Vol. 4, p. 271) may probably have rested upon Leech's misidentification of semistrigata, which I men¬ 
tioned under the latter. — ab. debrunneata Heydemann. Apical red-brown patch undeveloped. Founded on a debrunneata. 
Dresden $. — szechuanensis Wehrli (14 e). A well differentiated race from W. China (Ta-tsien-lu and Kunkala- szechuanen- 
shan) and Tse-ku. Larger than the European, colour violet-grey rather than white; face lighter than in b. bio- SIS - 
meri; proximal boundary-line of the apical patch red-brown, not deep black; the red colouring of the apical 
spot much reduced. 
D. syngenes Wehrli (14 e). Very similar in habitus to b. scechuanensis but distinguishable at a glance syngenes. 
by the long, prominent, black central streak, the considerably more strongly excurved postmedian and the 
white hindwing, with differently placed cell-streak. Face light yellow-brown (not dark-grey, as in nigrifurca). 
Founded on 1 from (Chinese) Tibet. 
D. nigrifurca Prout (16 e), founded on a few specimens from Hpimaw Fort, Kachin Hils, is recorded nigrifurca. 
by Wehrli from Siao-lu, one example. Much less wdiite than the preceding, cell-mark of forewing continued to 
costa, postmedian much less strongly and sharply outbent, etc. 
I), lilacina Warr. meianograrnma Wehrli (1 4 f) is a small form (25—26 mm against 27 — 32) of a melanogram- 
high-altitude Sikkim species, less reddish (more grey-violet), the lines dark grey to black instead of red-grey, the ma ' 
hindwing above with a more distinct postmedian, a visible (though faint) cell-dot. and 2 visible subterminal 
lines, the fringes beneath more distinctly divided, with only the outer half whitish. Ta-tsien-lu, a series; 
also 1 C from Kunkala-Shan. - rala subsp. nov. is much nearer to meianograrnma than to lilacina in co- rala. 
louring, but is larger (31 mm) the black of the costal part of the lines of the forewing more intense, the hind¬ 
wing without cell-dot, the fringes whitish throughout, only with very faint and strongly interrupted traces 
of a fine grey dividing-line. Kashmir: Rala (Me Arthur) type $ in the British Museum; Kashmir Valley 
(Colonel Ward), an identical 2 in the Tring Museum. 
D. violettaria Wehrli (14 e). At once distinguishable from the otherwise similar meianograrnma by violettaria. 
the much narrower median area and the slenderly black postmedian line not prominently thickened in the 
costal half. Palpus somewhat longer. Antennal ciliation shorter. 1 from Ta-tsien-lu. kukunoora Wehrli kukunoora. 
is smaller, the forewing less strongly suffused with violet, lighter (especially in basal and subbasal part), 
postmedian more weakly excurved, hindwing whitish, almost without markings. Koko-nor, 2 Co-

examples from Ta-tsien-lu, the principal habitat of kioudjrouaria Oberth. With examples of both before me, 
I cannot substantiate the difference of shape (see Vol. 4, p. 271), which I assumed from Oberthur's figure. 
The other distinctions, however, usually suffice and if eucosma is really a form of kioudjrouaria it is a very 
pronounced dimorph, deserving of a separate name. Djakonov adds S. Kansu to its known range. 
D. inefficax sp. n. (16 e). Very similar to kioudjrouaria, of which it may well be a subspecies, al- inefficax. 
though the termen of the hindwing is a trifle more produced; forewing much paler, the irroration on the white 
ground-colour being less dense and less dark, the lines, especially the thick postmedian one, less dark, the 
dots on the veins much less conspicuous, the dashes on the postmedian shortened; terminal dashes narrower. 
Hindwing more weakly marked, especially in its proximal part, the cell-dot. almost or quite invisible. Fringes

identified as phasma; but only the following yet. known to me: type $ in the British Museum; 2 CS ’ n the 
Tring Museum, one an aberration with the brown patch between the proximal parts of the 2rd radial and 
1st median developed, though not intense (wanting in the other examples of which I have any information): 
1 C and 1 $ in the Wehrli collection, the latter considerably the more strongly marked (but partly because 
the $ is not very fresh). 1 was mistaken in assuming (Vol. 4, p. 270) that this was a possible race of conisaria. 
D. naparia Oberth. (Vol. 4, pi. 8 d). As will be seen from a comparison of our figure (copied from Ober- naparia. 
thur) with that of Atopophysa indistincta (Vol. 4, pi. 13 e) there is no near resemblance between the two and 
Leech’s incorrect synonymy (Vol. 4, p. 267) must be deleted. “Certainly no Atopophysa; palpus much shorter; 
fovea wanting; antenna slightly serrate, with ciliation about 1” (Wehrli, in litt.). Oberthur distinguishes
