it from Ichraria by the relatively broad clear median area of the forewing; evidently also the postmedian 
and subterminal lines are less angular. Dr. Wehrli tells me the serration and ciliation of the antenna are some¬ 
what less strong and the face browner, less whitish (but perhaps damaged). 
D. tchraria Oberth. (Vol. 4, pi. 8 d). Dr. Wehrli (in litt.) tells me that 1 was probably correct in sepa¬ 
rating accentuata as a subspecies from this, of which he has 3 36 from Ta-tsien-lu. He has 2 very weakly 
marked 33 from Koko-nor which may probably represent a race deviating in the reverse direction, 
accentuata Prout (16 e). The original series consisted of 4 from Pu-tsu-fong and 1 from Chow-pin-sa; Wehrli 
adds 2 36 from Siao-lu, variable in that one has the blackening of the ante- and postmedian almost con¬ 
tinuous, while in the other it is interrupted behind the middle, the latter being the nearer to the typical tch¬ 
raria: structure the same. We figure the type 3 °f accentuata. 
I), conisaria Hmps. hypoconia subsp. nov. (1 G f). The topotypical conisaria , from Yatong, Tibet, and 
tire Sikkim specimens, so far as known, are somewhat variable, but strongly black-dusted and the Koko-nor 
species mentioned on p. 270 of Vol. 4 is not conspecific (see inefficax above). We are left with the Kashmir 
form to which I have given the name of hypoconia; paler than the name-type, the irroration being less 
black. Although I know at present only the type 9 (from Rala, Me Arthur, in the British Museum) and 
the Kashmir Valley $ here figured. I suspect they represent a good local race. 
D. phasma Btlr. (Vol. 4. pi. 13 m). Although the discocellulars of the hindwing are sometimes scarcely 
biangulate, I still think the present is the correct generic position. Corea is to be added to its range. 
D. biangulata Sterneck is unknown to me, but it is suggested that it might be placed next to phasma. 
The discocellulars, however, deviate from the normal in the opposite direction, being biangulate in the 
forewing also, a character which is sometimes regarded as generic. 3 antenna almost simple, only mi¬ 
nutely pubescent. Size of a large V. cambrica. Whitish, dulled with a sprinkling of brownish scales. Fore¬ 
wing with 2 faint basal lines; antemedian somewhat dentate on the veins, arising from a rather large red- 
brown costal spot; postmedian slightly curved outward on the 3rd—4th subcostal, thence almost straight, 
strong and black as far as the 2nd median, thence only traceable as a quite slender line; a rather broad red¬ 
dish brown line accompanying the postmedian, on the 1st radial with an acute projection, at the 1st median 
joined to the postmedian line by a dark brown spot; subterminal bordered by grey shades, which arise from 
small red-brown costal spots. Hindwing distinctly, though weakly, angled at the 3rd radial; 4 slender lines, 
the first crossing the cell-dot. Ta-tsien-lu, 2 33. 
D. apicistrigaria Djakonov, only known from a single, rather worn 9> agrees with biangulata in the 
unusual venation, but is much smaller (length of a forewing scarcely 12 mm). Palpus very short and slender, 
curved. Somewhat recalls Hydrelia testaceata , but is much narrower winged, with termen much more oblique; 
white, with copious black irroration; lines of forewing apparently very weak, but all strengthened at the costa; 
proximal lines merely indicated, incomplete, the 3rd one somewhat better developed, parallel with antemedian, 
ending in a small black spot at hindmargin; median area not darkened, of equal breadth throughout, its boun¬ 
dary-lines brown, thick anteriorly, slender behind, the postmedian (much as in testaceata) on the veins some¬ 
what dentate outward and blackened, its projections at, and concavity between, radials 1 and 3 distinct but 
not extreme; cell-dot of forewing small but distinct, of hindwing indistinct; the latter wing is, as in so many 
of the group, weaker-marked proximally than distally. S. Kansu: Kung-ta in Ka-tien-kou, at ca. 2850 m, 
18 July 1930. 4 99 from Yunnan (Mekong-Yangtse Divide, S. E. of Atuntza, 12000 feet, 20 Jidy 1922, Prof. 
J. W. Gregory), all extremely worn, may belong here, though the hindwing looks darker, etc. 
D. pallidaria Hmps. (16 f), founded on a single 3 , in poor condition, from Thundiani, has since been 
obtained from some localities in Kashmir; Prof. T. B. Fletcher collected a good series at Gulmarg in July 1931. 
Very distinct in its pale yellowish colour; median area of forewing narrow, its boundary-lines not much angled, 
the postmedian often forming a small spot at the base of 3rd radial and 1st median. Variable, the markings 
at times very weak, even in fresh specimens; least weak at costa; we figure an unusually strongly marked 3 
in order to show their arrangement. Antennal ciliation minute; discocellulars of hindwing well biangulate. 
D. albinea sp. n. (16 f). Expanse 23— 27 mm. Palpus and antennal ciliation extremely short. Recogni¬ 
zable at once by its clean white ground-colour and by the form of the double (on the forewing somewhat band¬ 
like shaded) postmedian and of the subterminal, both of which strongly recall those of the larger and much 
yellower A. chrysidia Btlr. (Vol. 4, pi. 10h) but without the longitudinal streak; antemedian of forewing much 
closer to the (minute) cell-dot than in that, not angled, generally weaker; terminal dots minute, sometimes 
quite weak. Underside, at least of the hindwing, very weakly marked; forewing sometimes with the anterior 
half of the postmedian rather strong. Punjab: Khyra Gully, road to Rawalpindi (H. Roberts) 4 33 • 5 9 $
